I recently had the opportunity to test multiple 3D printed shoes at a major international trade show, including fully printed lattice designs worn for extended hours on hard exhibition floors. Beyond simply trying them on, I stress-tested comfort, breathability, durability, and practicality while also speaking directly with industry leaders developing the next generation of 3D printed footwear.

This guide breaks down what 3D printed shoes actually are, how lattice structures work, which brands are leading the space, and whether fully printed footwear delivers real advantages over hybrid designs. If you are wondering whether 3D printed shoes are comfortable, durable, sustainable, or even possible to print at home, this in-depth overview will give you clear, experience-based answers.

Why 3D Printed Shoes Matter Now

3D printed shoes have moved beyond experimental concept pieces and into real products that people can actually wear. What started as futuristic lattice prototypes is now evolving into fully printed footwear systems that challenge traditional manufacturing, materials, and even brand models. The conversation is no longer about whether 3D printing can produce shoes, but whether it can improve how shoes are designed, customized, and distributed.

With major brands exploring lattice midsoles and emerging companies producing fully 3D printed structures, the footwear industry is quietly entering a digital manufacturing shift. For makers, designers, and technology enthusiasts, this is more than a trend. It represents a potential rethinking of production, ownership, and personalization in one of the world’s largest consumer product categories.

What Are 3D Printed Shoes?

3D printed shoes fall into two main categories. One approach uses 3D printing to produce a lattice midsole while the rest of the shoe, including the upper, remains traditionally manufactured. These lattice structures are designed to provide tuned cushioning, energy return, and visual impact, but they represent a hybrid model rather than a fully printed product.

Fully 3D printed shoes take a different approach by producing the entire structure as a single printed form. Instead of combining printed and conventional components, the whole shoe is manufactured through additive processes. This removes tooling and assembly steps and opens the door to digital customization, but it also introduces new questions around comfort, durability, and scalability.

The Technology Behind 3D Printed Footwear

At the core of most 3D printed footwear is lattice geometry. Instead of solid foam, these shoes use engineered cellular structures that can be tuned for cushioning, flexibility, and energy return. By adjusting the size, density, and orientation of the lattice, designers can control stiffness in specific zones of the sole, directly influencing comfort and durability.

Materials play an equally important role. Most 3D printed shoes rely on elastomer-based materials such as TPU or flexible polymers that combine resilience with fatigue resistance. Industrial systems often use advanced nylons or performance elastomers, while makers experimenting at home typically rely on flexible TPU filaments. The material choice determines not only comfort but also lifespan and structural integrity.

From a manufacturing perspective, selective laser sintering has become the dominant process for functional footwear due to its ability to produce strong, flexible lattice structures without support material. Resin-based systems can achieve fine detail and consistent elasticity, while FDM printing remains more accessible but limited in long-term wear performance. Hybrid models combine printed components with traditional uppers, bridging digital and conventional production.

Beyond hardware, 3D printed footwear introduces a different design workflow. Digital modeling, foot scanning, and iterative prototyping allow for rapid refinement without tooling changes. While true mass personalization is still evolving, the shift toward scan-to-production pipelines signals a future where fit and structure can be digitally optimized before a shoe is ever manufactured.

Major Brands & Players in 3D Printed Shoes

Zellerfeld

Zellerfeld represents one of the boldest interpretations of fully 3D printed footwear. Unlike hybrid shoes that combine traditional uppers with printed midsoles, Zellerfeld produces shoes as a single 3D printed structure, removing conventional tooling, glue, and multi-material assembly from the equation.

What makes their shoes particularly interesting is not only the manufacturing approach, but the business structure behind it. Designers and creators are reportedly granted up to 60 percent backend royalties per shoe sold rather than receiving a traditional affiliate commission. This shifts the relationship from promotion-based income to product ownership, giving creators long-term participation in the product’s success.

The brand has already attracted high-profile collaborations, including celebrities such as Justin Bieber. In one notable example, Bieber teamed up with Zellerfeld to 6080电影 a fully 3D printed soccer-inspired sneaker for his SKYLRK brand, further pushing 3D printed footwear into mainstream culture and fashion discussion.

In the 3D printing world, David Tobin (Executive Producer at 3D Printing Nerd Channel) also surprised the community with the release of the JoelBot D7, a limited edition version of his original D7 shoes. The short 3DPrintingNerd’s video highlights a customized D7 sole design featuring a textured outsole with a distinctive JoelBot character pattern integrated directly into the tread. This personalized detail reinforces the creator-driven approach behind the collaboration and shows how fully 3D printed footwear allows branding and design elements to become part of the structure itself.

Foot scanning is becoming a key part of the 3D printed footwear workflow. Instead of relying solely on traditional sizing charts, some brands use browser-based scanning systems that allow customers to capture the shape of their feet using a smartphone camera. This digital input can then be used to adjust fit and structure before production, moving closer to true mass customization rather than standardized sizing.

Adidas 4D and the “Lattice Midsole” Era

Adidas helped push 3D printed footwear into mainstream visibility with its 4D series developed together with Carbon. Today, a number of Adidas 4D derivatives are available for both men and women, combining traditional sneaker construction with a visually distinctive 3D printed lattice midsole. When I briefly checked current pricing in the US, some models were already available from around $100 with discounts applied.

In the Adidas 4D approach, the lattice midsole is the 3D printed component, while the upper part of the shoe remains traditionally manufactured. This hybrid construction allowed brands to introduce additive manufacturing into existing footwear production workflows without fully redesigning the entire shoe around 3D printing.

This approach likely scaled first because it focuses on one of the most important functional areas of footwear: cushioning and energy return. The lattice structure also became a strong visual signature, helping consumers immediately recognize that the shoe contains a 3D printed element.

From my perspective, Adidas 4D played an important role in normalizing 3D printed footwear for mainstream audiences. At the same time, it still represents a hybrid product rather than a fully 3D printed shoe. While the lattice sole demonstrates the advantages of additive manufacturing, the upper remains tied to conventional production methods.

Carbon played a major role in this movement by developing the Digital Light Synthesis (DLS) technology used to manufacture the lattice midsoles. Their partnership with Adidas became one of the earliest large-scale examples of 3D printing entering commercial footwear production. Special thanks to Andrew Sink for the walkthrough and discussions at the Carbon booth during Formnext.

Fully FDM 3D Printed at Home – Challenges

Now and then on social media, it is possible to spot fully 3D printed shoes made from TPU using large volume desktop FDM 3D printers. I personally did not have the chance to print and wear a full pair yet, but I had a great opportunity to speak with people who successfully printed and tested such shoes in everyday conditions.

From those conversations, it became clear that while printing wearable footwear at home is absolutely possible, it still comes with challenges around sizing, print time, flexibility, durability, and long-term comfort. Material choice also plays a major role, with softer TPU blends behaving very differently from more rigid formulations.

Nevertheless, despite all these obstacles, fully 3D printed shoes continue gaining popularity within the maker community. More users are printing wearable footwear at home and sharing valuable feedback about comfort, durability, sizing, and material behavior. Collections of shoe models on MakerWorld keep growing with increasingly impressive and experimental designs. Use a quick ‘Shoes’ or ‘TPU Shoes’ in search.

Apart from the very popular Whaleberry design by Cloudberry shown in the image, I also liked the CityStep – Casual, Everyday Sneaker by DjangoCashflow. It is especially helpful to read user opinions and browse shared test prints in the profile and comment sections of these shoe models.

Comfort, Durability Testing

To test long-term comfort and durability, I wore the same pair of Flux shoes at the Formnext trade show in Frankfurt. Two full days of walking across multiple exhibition halls turned into an excellent field test. The shoes handled the event surprisingly well: no noticeable deformation, a good grip on polished floors, and consistent cushioning throughout. Honestly, I expected blisters; I got some when I was wearing standard shoes at events a few years ago, but this time it never happened.

This is also where I tested them with Formnext-branded high socks. High socks are almost inevitable in winter in northern countries to keep the cold out.

I am not the only one who tested 3D Printed shoes on the trade flor. At 3d printing or Am related tradeshow it is a high chance to meet a both representative or even visitors who wear them – stop and talk about their shoes I am shure they will have insignfull stores about their 3D printed shoes.

I am not the only one who tested 3D printed shoes on the trade show floor. At 3D printing or additive manufacturing related trade shows, there is a high chance of meeting both representatives and visitors wearing them. Stop and ask about their shoes, I am sure they will have insightful stories and experiences to share about their 3D printed footwear.

Who Should Consider 3D Printed Shoes?

As 3D printed shoes become more accessible, I would not necessarily recommend buying a budget FDM or desktop resin 3D printer solely for printing footwear at home. Between printer cost, materials, maintenance, space requirements, print failures, and the experience needed to produce wearable results, it may currently be easier and more practical for many users to purchase an existing model in the around-$100 category.

At the same time, for makers who already own a larger-volume printer and enjoy experimenting with functional TPU prints, 3D printed footwear can become a very exciting direction to explore. Beyond personal projects, the growing interest around customized footwear and printable shoe models may even open opportunities for small-scale business ideas and local customization services in the future.

Final Verdict: Are 3D Printed Shoes Ready?

3D printed shoes are no longer just futuristic concepts. From mainstream lattice midsoles to fully 3D printed footwear and home TPU experiments, the technology is already becoming part of real everyday use. While the space still feels early in some areas around fit, durability, and long-term comfort, the progress is happening fast. After testing multiple pairs and speaking with people actively wearing them, I genuinely believe 3D printed footwear is moving in the right direction and will continue evolving rapidly over the next few years.

3D printing has already transformed prototyping, manufacturing, and even home décor, and now it’s stepping confidently into footwear. For me, as someone who has spent more than a decade surrounded by additive manufacturing, trying a fully 3D printed pair of shoes feels both exciting and strangely personal. PollyFab’s lattice shoes are a great example of how advanced 3D printing can meet everyday fashion in a practical, wearable form. I tested them over several weeks, including a real-world “torture test” at the Formnext trade show in Germany, to see how they perform in terms of comfort, design, and day-to-day usability.

Design and Lattice Structure

PollyFab’s shoes are made entirely through 3D printing, using a flexible lattice geometry that replaces the need for traditional soles, insoles, and stitching.
The open mesh pattern allows air circulation and gives the shoes a springy, cushioned feel. Available in black, white and orange, they arrive neatly boxed with stuffed interiors to maintain shape.

I was especially impressed with the black Flux from the beginning. I originally asked for the striking orange version, but it was unavailable. When the black pair arrived, I liked the look almost instantly. The design clearly says that it is 3D printed, and after more than ten years in this industry, that alone gives me a real dopamine kick. It even reminds me of the feeling I had as a kid when I saw the black Knight Rider car. The shoes have a similar cool and futuristic vibe that feels strongly connected to additive manufacturing.

Bare Feet or Socks?

To understand how these shoes behave in real daily wear, I tested them both barefoot and with different socks. I was curious to see how much the look, comfort and fit would change, especially with the open lattice structure.

Bare feet, of course, make these shoes look the coolest, but I tried them with both high socks and low socks as well. I have a few pairs of Union Jack low socks in different designs, and they all work surprisingly well with these shoes.

I asked my wife to try the white Aero shoes that were delivered in her size. When we tested them, it turned out the pair was slightly larger than her actual foot length. Nevertheless, the shoes still looked very good on her and the overall design suited her well.

Comfort and Fit

At first wear, the shoes feel surprisingly light and flexible. The lattice compresses naturally underfoot, adjusting to pressure points. While they lack a conventional arch, they remain comfortable for light walking and indoor use. I was initially surprised not to see any arch support, but even after stress-testing them for two days in a row at Formnext, I didn’t feel any related discomfort. The soft front section of the shoe absorbs most of the impact, which helps reduce fatigue.

After a 40-minute session on the cross trainer, I did notice a light imprint on my upper sole through the socks. I suspect that after one or two hours of this kind of training, when the whole body weight is concentrated on the upper sole, I might feel some numbness. This is where I should wear socks with extra padding.

Formnext Real-World Test

To test long-term comfort and durability, I wore the same pair of Flux shoes at the Formnext trade show in Frankfurt. Two full days of walking across multiple exhibition halls turned into an excellent field test. The shoes handled the event surprisingly well: no noticeable deformation, a good grip on polished floors, and consistent cushioning throughout. Honestly, I expected blisters; I got some when I was wearing standard shoes at events a few years ago, but this time it never happened.

This is also where I tested them with Formnext-branded high socks. High socks are almost inevitable in winter in northern countries to keep the cold out.

Another surprise was the temperature. I expected the open lattice structure to feel cold inside the trade show halls, but no, the temperature at Formnext was ideal, and I didn’t feel cold at all. Outdoors, in wet and cold weather, it is a different story. A five-minute walk from the hotel to the venue was okay as long as every puddle was carefully avoided. Step into one, and yes, the feet will get wet instantly.

Looking forward to trying these shoes again at other trade shows. And by the way, they are a fantastic conversation starter. It worked very well for me.

Airpuff One and Airpuff One Pro NEW

Airpuff One and Airpuff One Pro feel more like slipper-style shoes. They are very easy to put on without any assistance, which makes them convenient for quick outdoor use. The lightweight lattice structure gives them a soft and flexible feel straight away.

I gave the Airpuff One Pro a proper test when the weather finally cooperated. We walked to the park, had a BBQ, and continued on a small adventure walk all the way to the ice cream kiosk. Overall, it was a fun experience. The shoes felt very light and puffy, and to my surprise, I did not need to clean the lattice after walking over grass.

While having a BBQ in the garden without socks, everything felt great. On a longer walk, after about 30 minutes, I started to feel that I might need a plaster or two at some point.

How PollyFab Shoes Are Made

PollyFab’s lattice shoes are produced through advanced additive manufacturing using a custom, bio-based elastomer called ELASTO 1000 BIO, designed for high elasticity, resilience, and long-lasting flexibility. This specially engineered material allows the lattice structure to bend, compress, and rebound with each step, giving the shoes a springy, adaptive feel that would be difficult to achieve with traditional materials.

Rather than stitching or gluing parts together, the entire shoe, sole and upper included, is built as one continuous piece from digital design files. This lets PollyFab 6080电影 lightweight, breathable cushioning and complex lattice geometry in ways that conventional footwear manufacturing cannot easily replicate. For more details on the technology and philosophy behind the design, see the official PollyFab website.

Conclusion and Pros & Cons

Aero: Official Website
Flux: Official Website
Airpuff One Official Website
Airpuff One Pro Official Website

Another reason I enjoy these shoes so much is that they feel like a real glimpse into the future. Wearing fully 3D printed footwear makes me think about how quickly things are progressing. One day soon, we’ll scan our feet, drop a file into a home 3D printer, and produce shoes perfectly tailored to our own geometry. Whether the structure is lattice or something entirely new, the concept of a fully printed, custom-fit shoe feels incredibly close. Shoes like the PollyFab Flux and Aero act as a reminder that this future is not far away; it’s already partially here.

In the past, I looked skeptically at ‘3D printed’ shoes from major brands. Yes, their lattice midsoles are amazing, but the upper is still made with a different, inaccessible technology; it breaks the magic. For me, fully 3D printed footwear carries a completely different meaning. It’s authentic, maker-friendly, and aligned with the spirit of the open, experimental 3D printing community. With fully printed shoes like PollyFab, we’re getting closer to the moment when printing similar shoes at home becomes not only possible, but practical. Files will become more available, scanners will become simpler, and fully printed, customizable footwear will be within reach of anyone with a 3D printer.

Pros:
Lightweight and breathable
Visually striking lattice design
Comfortable for short-term wear and low-impact activity

Cons:
Some may prefer arch support
Not ideal for rough/wet outdoor use

Why Use Engineering-Grade Filaments?

When strength, durability, and thermal resistance matter, standard PLA and PETG just won’t cut it. That’s where engineering-grade filaments come in. These advanced materials — including Nylon, Polycarbonate (PC), and carbon-fiber-infused blends — are designed for real-world functional applications, from automotive parts to industrial prototypes.

In this guide, we’ll explore the most common types of engineering-grade filaments, what sets them apart, and how to print them successfully on compatible FDM 3D printers. Whether you’re working with carbon-fiber-filled Nylon or heat-resistant PC-ABS, understanding the properties and requirements of each material is key to getting professional-grade results.

Printer and Drying Equipment Requirements

Before we proceed to the engineering-grade materials, it’s important to highlight that in most cases, specific 3D printer capabilities and proper filament drying are essential for successful prints. These requirements will be mentioned again for each filament type individually, but here are the most critical hardware considerations:

• Enclosure: A fully enclosed printer is often necessary to prevent warping. A heated chamber is ideal for materials like PC or Nylon, CF.
• Heated Bed: The bed should reach temperatures up to 110°C for proper adhesion with some of the engineering filaments.
• Reinforced Nozzle: Materials like carbon-fiber-reinforced Nylon are extremely abrasive. Hardened steel, ruby-tipped, or nozzles made from tungsten carbide are recommended to avoid rapid wear.

Printer examples that meet these requirements include the Creality K2 Plus and the QIDI Plus4, both of which feature enclosed chambers and all-metal hotends.

Another essential piece of hardware is a filament dryer. Engineering materials are highly hygroscopic and absorb moisture quickly, which can ruin print quality. For best results, use a dryer capable of maintaining elevated temperatures over long periods. High-performance options like the SUNLU E2 are well-suited for Nylon and PC filaments that require higher drying temperatures.

Top Engineering-Grade Filaments

This guide is intended to remain evergreen and will be updated regularly as we test new materials and use cases on this website. So far, we’ve worked with several engineering-grade filaments, including PA6-CF (carbon fiber-reinforced Nylon PA6), PA12-CF (carbon fiber-reinforced Nylon PA12), PC-ABS in white (a blend offering strength and heat resistance), and Nylon PA6/66 (a durable copolymer blend). Each of these materials offers unique properties suited for demanding applications, and more will be added as we continue hands-on testing.

PC-ABS Print Examples

Use Case Examples & Tips:
While testing engineering-grade materials, one of our functional prints — a 3D printed roof window handle extension — failed after 1–2 years of daily use. It was originally made from PLA and couldn’t withstand the constant stress from frequently opening roof windows. Since I had a spool of Inslogic PC-ABS on hand (in white), I decided to reprint the part using that. After a few tuning attempts to get the bed adhesion right, the result was solid and functional.

As we continue testing and publishing more real-world use cases, this example shows how engineering-grade materials like PC-ABS can offer both strength and a clean visual finish. It’s a great reminder that with the right hardware and settings, these advanced filaments can deliver reliable results for demanding everyday applications.

PA6-CF – Carbon Fiber Nylon Print Examples

Use Case Examples & Tips:
To test PA6-CF, I chose to print components for a DeathRacer RC model. After seeing all the fun DeathRacer 6080电影网 organized by @TheRealSamPrentice at various RepRap festivals, I couldn’t resist joining in. While the official instructions suggest that these models can be built in PLA, using PA6-CF might be a bit overkill — but it served my testing purposes perfectly. The distinctive matte finish and textured feel of PA6-CF give the parts a seriously cool and professional look.

PA6-CF is a lovely material to work with when your project demands both strength and aesthetics. For the best results, be sure to check the Inslogic PA6-CF product page for detailed printing and optional annealing settings. These can help fine-tune the part’s mechanical properties even further.

One important consideration with PA6-CF is safe handling: during sanding or prolonged exposure to airborne dust, carbon fiber particles may pose respiratory irritation risks. It’s best to work in a well-ventilated area and use appropriate protection such as a dust mask or respirator when post-processing.

Difference Between PA6-CF and PA12-CF

Before moving on to PA12-CF, it’s worth highlighting the key differences between these two materials. At first, I found it a bit confusing — the names are nearly identical, and even when printed, the parts texture looked quite similar. However, as you’ll see in the table below, there are some important differences in performance, handling, and moisture sensitivity that can affect your print success depending on the application.

PA12-CF

Use Case Examples & Tips:
We’ve begun testing PA12-CF and will be sharing full results shortly. While visually similar to PA6-CF, PA12-CF tends to offer improved dimensional stability and better moisture resistance, making it easier to work with in environments without ideal filament drying setups. This material is especially promising for prints that need long-term accuracy without warping.

Typical use cases for PA12-CF include drone frames, lightweight mechanical housings, automotive clips and fixtures exposed to moderate heat, functional enclosures requiring dimensional stability, wear-resistant jigs and brackets, tooling components, mountings for electronics, durable hinges and latches, and industrial prototypes designed to withstand humid or variable environments. Its combination of stiffness, low moisture absorption, and ease of printing makes PA12-CF suitable for a wide range of functional and semi-structural applications where reliability and consistency matter.

Vase Mode in PA12-CF

Another engineering-grade material tested on the Creality K2 Pro is PA12-CF by Inslogic. It looks nice, and the finish resembles popular galaxy composite filaments. With the default 0.4 mm nozzle, this vase is understandably very fragile.

There is a big collection of anti-sphere vases available on Printables. Marcidi shared this collection on our forum. This is the default size. For functionality, such as a rubbish bin or a vase for dry flowers, I would print it bigger and with a larger nozzle.

Nylon PA6/66

Use Case Examples & Tips:
We’ve recently received a spool of Nylon PA6/66 from Inslogic and will be sharing full testing results soon. This copolymer blend offers a balance between the strength and rigidity of PA6 and the flexibility and improved processability of PA66, making it a versatile engineering-grade material. While it shares some characteristics with carbon fiber-reinforced nylons, PA6/66 typically provides slightly more ductility and can be easier to print under less abrasive conditions.

Typical use cases for Nylon PA6/66 include impact-resistant mechanical parts, snap-fit enclosures, gears and bushings, brackets, fixtures, cable guides, tool holders, and functional prototypes that require both durability and a degree of flexibility. Its balance of mechanical strength and chemical resistance makes it suitable for engineering environments, workshop tools, and end-use components subject to stress and minor deformation. When properly dried and printed with the right hardware setup, PA6/66 can offer excellent performance in both indoor and semi-industrial applications.

Challenges and Safety

Engineering-grade filaments require more attention than standard materials like PLA or PETG. Proper filament drying is especially important — materials such as Nylon and PC-ABS are highly hygroscopic and can absorb moisture quickly, leading to stringing, poor layer adhesion, and weak prints. Using a reliable filament dryer and storing spools in a sealed, low-humidity container is strongly recommended. Additionally, a fully enclosed 3D printer with a heated bed (typically up to 100–110°C) is essential for maintaining consistent print quality and reducing warping, especially when working with high-performance materials like PA6-CF or PC.

– Safety. It’s also important to take safety precautions when printing and handling these filaments. Some materials may emit fumes or fine particles during extrusion, and carbon fiber-filled variants in particular can release airborne fibers during sanding or post-processing. Always work in a well-ventilated area and consider using a HEPA filter or air purifier alongside your printer. When post-processing, wear appropriate personal protective equipment such as a dust mask or respirator. In some cases, even gloves are recommended, as fine particles may cause skin irritation or rub into the skin during handling. Taking these steps ensures you can safely use engineering-grade materials in a home or workshop setting without compromising health.

Conclusion

It’s exciting to see engineering-grade filaments becoming more accessible to a wider audience. Materials like PA6-CF, PA12-CF, PC-ABS, and PA6/66 are no longer limited to industrial use — with the right hardware and preparation, they can now be successfully printed in home and small workshop environments. As long as appropriate safety precautions are followed — especially regarding ventilation, particle exposure, and handling — these advanced materials open the door to durable, functional, and professional-grade results for makers, engineers, and hobbyists alike.

Workshop Visit and Student Project Overview

The visit began with a guided tour of the Engineering Department led by Matteo Cascini, where I had the chance to see the facilities that support the Riviera Racing team’s work. From prototyping labs to electronics and materials workshops, the department offers a hands-on environment that encourages cross-disciplinary collaboration and innovation.

It was also fascinating to explore other parts of the department and get a glimpse of how things operate at the world-renowned University of Cambridge.

Snapmaker in the Workshop

While the boat testing stole the show visually, a quick tour through the department’s workshop revealed some of the tools that made it possible. Among them was the Snapmaker Artisan, a 3-in-1 digital fabrication machine capable of 3D printing, laser engraving, and 6080电影网 carving, as well as the Snapmaker J1s – a high-speed IDEX printer.

The list of 3D printed components featured in the project includes:

• Rear structural clamps (replacing heavy plywood blocks)
• Steering wheel mount, steering cable drum, and dashboard screen casing
• Rear steering bicycle wheel mount
• Propeller cavitation plate mount
• Throttle casing
• Hull conversion project spacers and drilling jigs
• Electronics housing in the battery case
• Propeller prototypes

For part design and preparation, the team primarily used SolidWorks for CAD modeling and Snapmaker Luban as the slicing software for 3D printing workflows.

Although not the only machine in use, the 3D printers played a significant role in creating functional prototypes. According to the team, several boat components were produced using PLA filament, including replacement parts that previously utilized wooden elements, such as bracket holders.

Real-World Prototyping in Student Engineering

The student-led Riviera Racing team is working toward a sustainable maritime future by building a zero-emissions boat, which they plan to enter in the 2025 Monaco Energy Boat Challenge, a major marine engineering competition.

– Under  Pressure. The team faced a slight delay during the lake testing, as the engine initially failed to start. However, through calm and methodical troubleshooting, they managed to resolve the issue and get the boat running smoothly. This moment not only highlighted their technical capability but also their resilience under pressure — a trait as valuable as engineering itself.

The Riviera Racing team is composed of dedicated students specializing in various aspects of the project. In the group photo, from left to right:

• Karthik Nachippan (Software and Propulsion Engineer)
• Max Funkner (I wish I were a part of the team)
• Harsh Sinha (Co-captain and Director of Operations)
• Matteo Cascini (Body & Structures Lead)
• Sanadi Ilandaridewa (Deputy Chief Engineer: Electrical)
• Oliver Flavin (Pilot and Propulsion Lead)
• Gereon Leckebusch (Propulsion Lead)
• Henry Means (Body & Structures Engineer)
• Max Weston (Deputy Chief Engineer: Mechanical)

Many of the Riviera Racing team members are also active on LinkedIn, making it easy to follow their ongoing projects and professional journeys beyond this initiative.

Riviera Racing’s approach blends academic engineering with real-world design constraints. Seeing a boat transition from CAD to water, with students responsible for everything from electronics to propulsion, showcased the strength of project-based learning.

The project also demonstrated how affordable digital fabrication tools, like those offered by Snapmaker, can empower student teams to iterate quickly and test efficiently.

2025 Year’s Goals

The Riviera Racing team continues to push boundaries with ambitious goals for the current development cycle. Among the key focuses are reducing the boat’s overall weight and improving efficiency through emerging technologies.

They are already exploring the use of hydrofoils, hydrogen fuel cells, and computer vision powered by AI to enhance future designs. Lightweight, custom 3D printed components are expected to play an even greater role as the team works toward optimizing structure and performance.

The team is aiming to conduct two to three additional testing sessions before the competition in Monaco, all while balancing final exams and academic commitments. The Monaco trip itself spans up to seven days, marking a major milestone in their calendar as they prepare to represent Cambridge on an international stage.

This official video from the Riviera Racing team offers a closer look at their goals, engineering process, and testing experience.

Update: Monaco Competition

In July 2025, the Riviera Racing team successfully made it to the prestigious Monaco Energy Boat Challenge, competing among 20 international teams. Despite an unfortunate electrical failure caused by salt corrosion that prevented them from entering the final race, the team still achieved an impressive 10th place overall. Their preparation, adaptability, and enthusiasm on-site were evident throughout the event. The experience not only marked a major milestone in their journey but also strengthened their resolve for future races, including a planned return in Sardinia this October.

Handle Extenders and Helpers

If someone asks me what is the most used object that I have ever 3D printed, I would answer that it is a roof window handle extension – a customized tool that helps me and my family to open and close windows in a bathroom and bedroom that are too high to reach.

3D Printed Tools & Tool Holders

Functional Wrench

One of the most well-known objects in functional 3D printing is the wrench by Daniel Noree. Daniel is famous for his OpenRC models which are all functional. They say that if you manage to successfully print his wrench and make it work after removing the supports, then your 3D printer is calibrated well and the slicer settings are correct. We have to admit that our first attempt failed, but we got it right in the end. This model is very popular and was featured a lot in 3D printing related media.

Thorn Remover

Unique 3d printed tools can be used for such simple tasks as a rose thorn removing for example. Professional florists use thorns removers quite often. This could be a nice present for a gardener.

Tool Holder

For standard and 3D printable tools, it is possible to design and 3D print highly customizable holders just for specific cases. Elegoo added a nice test print file with their Neptune 3 Pro printers and it is one of the best examples. The full set of Allen keys fit perfectly into the tool holder, and the entire unit attaches snugly to the printer. Read the full review of the machine here.

3D Printer Toolheads

Check the two blogs by Andrew Sink who turned his 3D printers into food 3D printer and 2D printer pen plotter with printed at home toolheads respectively.

Fixes and Replacements

Do you have an office chair that keeps sinking under you? Chances are, you’ve got a failing gas lift cylinder on your hands. If you are the owner of a 3D printer, you can permanently fix your chair to the desired height with a simple 3D print job.

Recently functional 3d printing helped us to avoid a wardrobe disaster. One of the brackets holding a hanging rail broke sending all dresses down in a messy pile. We figured that it would be possible to design and 3D print the bracket. It took us 30 min to design and 2 hours to print the replacement in rigid.ink ABS.

While being designed, the brackets actually got upgraded, acquiring more strength and depth to support the rail. Disaster averted – the dresses are neatly placed back and waiting for their turn to go out

Brackets

This functional 3D printed item greatly helps to organize any 3D printing workspace as it holds a lot of filament spools. Joel Telling’s spool mounting bracket has been showcased and torture-tested in his popular videos. In addition, a themed 3D printing competition has been held on MyMiniFactory.

It is a popular trend in the 3D printing community to 3D print needed brackets for the filament shelves. My filament shelf story is not that peachy but with a happy end. PLA brackets broke after 3 years in service. Initially, they were wrongly printed as well, namely with no perimeter shells but only 20% infill. Look how the perimeter shells got split on one of the images. New reinforced ABS and PETG 100% infill brackets (plus one extra) are in place now.

It is important to keep in mind that not all materials are suitable for supporting heavy loads, and over time, plastic qualities might deteriorate. PLA, for example, may become brittle after a couple of years. ABS, PETG, and other stronger materials are much more suitable for such tasks. Also, it is recommended to print such an object solid with a 100% infill rate.

Holders

Pencil Holders

The majority of useful 3D models on STL sharing websites are different kinds of holders, equipment stands and mounts. We have printed an SD card holder, a mobile stand, a wine bottle holder and various accessories. Our very first functional 3d printing item was an Artichoke Pen Holder. It took us 20+ hours to print and it does the job very well.

Functional Mounts

Wall Mounts

An extra or replacement spool holder is frequently needed as well. We are very proud of our themed design – a 3D Printing Guardian spool holder as now we can replace a filament spool in seconds.

Bookshelf, Table Mounts

When we occasionally make a YouTube video, we use the headphones, but 99% of the time its wires lay around occupying space in the work area. Monster Headphone Holder by philbarrenger greatly helped to organize our workplace better.

Customized Nozzles

Of course, we tried to design something functional ourselves. Here is our simplistic model. There is a lot of dust collecting in hard-to-reach places around the house, for example, behind the radiators. This is probably a concern in many households. Our vacuum cleaner Henry didn’t have a suitable nozzle to get through narrow spaces. Therefore, we designed a customized nozzle in TinkerCAD. It consists of several parts and is easy to print.

Mobile Phone Cases

Another popular useful 3D print is a mobile phone case. There are many 3D printable files available on specialized platforms. These models are easy to customize further. Mobile phone cases are great as protection from breakage. For our mobile case, we used a beautiful orange flexible filament that has a nice rubbery non-slip surface.

Useful Noise Dampers

For some 3D printers, like Original Prusa, we would recommend printing additional accessories, for instance, noise dampers by Hofftari. These dampers significantly reduced the noise that made it possible to work overnight without disturbing anyone.

Useful Stoppers and Blockers

Useful 3D prints must not be labeled as boring. A good example is a Hodor Door Stop by fixers who were inspired by the famous episode from the Game of Thrones. There is a massive collection out there in the jungle of file 6080电影网站. Very easy to design and modify the way you want. PTT teaches his students to design such objects in week 1 of the Blender 3D design for 3D printing course.

Here is another easy design that appears to be very functional and even money-saving: Temporary Flap Vent Blocker. As the winter temperature greatly plummeted and the heating bill skyrocketed, I checked for solutions to decrease drafts around the house. As a temporary solution, I decided to block my Ducting Air Vent for a short duration with a simple design.

The model can be found on Cults. The model is easily adjustable according to the measurements between the screws and has a simple feature to grab with the nail for removing it from the flap vent.

3D Printing Functional Lamp Shades

There are a lot of STL models for free and a small fee on file 6080电影网站 that would give you original ideas on how to upgrade the interior with gorgeous 3D printed lamp shades and light systems. Initially, we looked at this trend with a bit of skepticism as weren’t sure about the fire safety. Check out our blog on 3D printed lamp shades.

Disclaimer: We can’t stress enough that every electrical appliance is a potential fire hazard if treated/maintained inappropriately. Therefore, extra care has to be taken while undertaking any 3D printing DIY project that involves 6080电影网站.

Pots and Planters

File 6080电影网站 offer a vast collection of plant pots or planters that can be 3D printed. Vases and pots usually are desktop 3D printer-friendly and any filament can handle the task.

Recommended material for the pots and planters is PETG as it is more waterproof and less biodegradable than PLA.

Disclaimer. The object described in this article is only an idea with an example STL file. The design is in testing and we won’t bear any responsibility for any accidental damage to the property if such occurs.

Disclaimer. Before printing this item, make sure the measurements match your specific window handle.

Telescopic Poles and Adapters

There are an official pole and adapters available for a particular window type usually found in lofts or attics. These would work in most cases, especially with the higher-positioned windows. But, when a roof window is used daily, our custom handle extension solution may be worth looking at. As a bonus, there is no need for a long pole that takes extra space to keep.

Before going further, there is one thing that is important to mention in any case. Maintain your windows by applying some lubricant solution to the hinges once in a while.

Designed in Blender

Once I started exploring Blender, I prefer to stay on it as it is a sandbox and has it all. As usual, it all started with the cube which got expanded, sides and faces extruded into a lever-looking object. The top part was measured to fit the original window handle and the rest of the object was stretched to fit the Snapmaker A350T build platform diagonally. The final object is 380mm (15 inches) long.

The Subdivision Surface modifier helped to smooth the sharp corners of the handle, while the Edge Crease option made sure the base of the object was flat and printable.

I think it is possible to make this object a bit fancier by adding a curve, for example, or applying some texture. As this object is still in the testing phase I left it as it is.

Material of Choice

For the testing purposes, I used the material I had. And below are the results. Please mind that we open our windows a few times per day.

Handle One
Material – PLA Plus. Environment – bathroom. I knew from the beginning that PLA will struggle to last long in a room with high humidity levels. So, the toughest I had was reinforced Black PLA Plus by SUNLU. This filament produces strings, requires higher temperatures, and has poor bed adhesion. Generally, the qualities are similar to PETG. Result – still works after 2 years (some visible cracks but still works).

Handle Two
Material: Wood PLA – failed after 9 months. Then print in ordinary PLA failed after 1.5 years.

Update: Engineering Grade Materials

While testing engineering-grade materials, one of our functional prints — a 3D printed roof window handle extension — failed after 1.5 years of daily use. It was originally made from PLA and couldn’t withstand the constant stress from frequently opening roof windows. Since I had a spool of Inslogic PC-ABS on hand (in white), I decided to reprint the part using that. After a few tuning attempts to get the bed adhesion right, the result was solid and functional.



These roof handles are definitely heavy-use, day-to-day functional parts — you can see them in action in this short video. Now that the design is printed in a much more reinforced filament, there’s hope it will last significantly longer. However, engineering-grade materials come with their own set of challenges: they require specific machines with reinforced nozzles, enclosures, heated beds up to 110°C, filament dryers, and proper bed adhesion solutions. If you’re interested in learning more about how to work with these advanced filaments, check out our full guide on Engineering-Grade Filaments, complete with settings, tips, and use case examples.

How to Print – Slicer Settings

FDM 3D printing has some weaknesses that should be addressed when slicing an object that will have to resist certain forces. Our extension handle should be printed horizontally only with many perimeter shells.

Excessive perimeter shells (wall line count) and high percentage infill add to the object weight and printing time. When I was tuning the slicing settings, I focused on the area where M3 40mm screw and M3n locking nut will sit. To make sure the plastic will be consistent there to melt properly and withstand certain forces.

3D Printer of Choice

As I mentioned before, the roof window extension handle was scaled to fit the print bed. Initially, it was the Snapmaker A350T 3D printer that the object had to fit. Snapmaker with the enclosed chamber can be good for printing such items in materials like ABS or Carbon Fibre-type filaments, for example. The controlled environment in the enclosed chamber helps against warping.

The second printer of choice was Elegoo Neptune 3 Plus. Luckily, the same STL, without scaling a model, fit the print bed diagonally.

On large print beds like on Elegoo Neptune 4 Max (420 x 420 x 480mm), Anycubic Kobra Max (400 x 400 x 450mm) such a tool could be made even longer, approximately up to 500mm (19.6 inches) long.

There are 3D printers that are initially designed to print objects that are long but low. Such printers are highly likely to be custom-built, rare, and therefore be much more expensive than the sub-$500 3D printers I featured above. Belt 3D printers are suitable for printing such objects, but the resulting print will be very weak and might break quickly. The fusion between the layers will be much weaker compared to that when printing horizontally with the continuous flow.

3D Printing 520mm (20.5 inches) Handle with Elegoo Neptune 4 Max

My roof window handle, 3D printed on the Elegoo Neptune 4 Max, came out to be 520mm (20.5 inches) long, which is 140mm longer than what I printed on the Neptune 3 Plus. This time, to reduce the weight of the object, I printed it partially hollow. Check my hollow settings here. Let’s see if there will be any issues. Still testing…

Just a quick note, for my continuous testing, this object is printed in PLA, but I would recommend printing such heavy-use objects in PETG or other stronger materials instead.

Roof Window Handle Extension Assembly

== DO NOT OVERTIGHT ==
The assembly is straightforward. I would recommend putting the nut in place before attaching the extension to the handle as it will be trickier to do afterward.

These are spare M3 bolts and nuts from my previous Prusa MK2 3D printer. Amazon’s equivalent: of the bolts and nuts.

Conclusion and Files

This is an object that I use on a daily basis. I am very proud of this model and the idea, and that I had a chance to bring my design and 3D printing skills to something useful at home. In the comments below, please let me know if there is a possibility to improve such a model.

3D printed prosthetics for animals is one of the areas where 3D printing can be invaluable in producing customized ingenious contraptions. This 3D printing application has been pulling them back to their active lifestyles or being used as part of the treatment. We have been witnessing the continued adoption of this technology in various spheres of our lives, with some amazing success and even life-saving stories.

This guide covers:

• 3D Printed Prosthetics
• Customized at the Right Time
• Amy’s Story – Special Needs Dogs
• Horses and Customized Horseshoes

3D Printed Prosthetics for Animals

3D printed prosthetics is featured frequently in the media. We also mentioned it in our 3D printing in the medicine guide. But here we will cover some remarkable stories when 3D printed prosthetics helps animals in need. In the following article, you will find the images and the case studies with dogs, birds, goats, and even a turtle. As we aim to keep updating this article, more stories will be added in due course. If you want a particular story to be featured here, please contact us.

Customized at the Right Time

There are plenty of professional prosthetics services and, in many cases, the solutions they provide are better than those 3D printed at home. But as training the animals to get used to the prosthetic device should start as early as possible, especially for the fast-growing youngsters, 3D printed at home customized devices can be really helpful and cost-cutting in the near term.

Dogs with Special Needs – Amy’s Story

Recently, Anycubic 6080yy a heart-warming story about dogs with special needs. Amy Jo Martin shared their story of how Mega X and Vyper 3D printers helped them to 6080电影 safety and mobility-enabling devices. With various levels of disability, these dogs had their lives improved.

With special needs dogs, partially because of their friendly and adaptive nature, such structures can greatly benefit them and help to live their lives in full. Usually, such structures are carts with wheels, that assist with the movement. Apart from the carts and movement helping structures, Amy 3D printed a helm for her little dog Jett who had neurological issues. As the result, Jett received both a quad cart wheelchair and a helmet.

Customized Horseshoes

Most of the stories we’ve heard in connection to using 3D printing in helping horses were about the hooves. As large animals, they need to protect their hooves from damage and general wear and tear. Traditional horseshoes require nails to be put into the hooves, and if a hoof is damaged or has inflammation, this turns into a painful procedure. Some horse carers called upon the vets together with 3D designers, 3D printing service agencies, or the machine manufacturers to find a solution.

Quite a few success stories came out of this practice. In one case, horses have been aided with customized horseshoes that could be easily changeable for the use on either harder or softer surfaces. In another case, the new flexible 3D designed and customized horseshoes allowed them to keep finding the right balance between the different parts of the hoof. This decreased pain and rebalanced the weight.

Birds with Damaged Beaks

There are a few remarkable stories out there about how 3D printing helped to re6080电影 the damaged beaks of the birds.
– Tieta the Toucan. The female bird had her beak restored. A detailed story was covered on BBC.
– Beauty the Bold Eagle. A story when the 3D printing technology helped to restore Eagle’s beak which was lost after a hunting incident.

Helms – Not Only for Rams

For humans, there are plenty of head protectors, segmented by standard sizes. When the animals are concerned, such items must be customized, and producing them in high volumes can be costly. We have been seeing helms 3D printed for goats and dogs successfully. Such safety features could be added for other animals who have scull vulnerabilities.

Sea Life – 3D Printed Shells, Reefs and Homes

Apart from prosthetics, it is worth mentioning that 3D printing helps to restore the ecosystem of coral reefs. A part of this are the new 3D printed shells for shellfish, and it is handy for saving some endangered species.

– Dolphin with an Artificial Fin. 3D printed artificial limb case. Fuji lost 75% of his fin due to a necrotic disease. A replacement fin for Fuji was made out of silicone, cushioned with foamed rubber, and reinforced with carbon fiber.

Conclusion

It is clear that with the 3D printing capabilities, the wide choice of materials, and customized designs, the lives of both animals and humans can be vastly improved. We’ve seen many attempts to 6080电影 3D printed prosthetics at home, which has been tested and improved with time. The technology is becoming more effective for these purposes, and we are sure to see other applications in the near future.

What is a 3D Printer, Anyway?

Before we talk about printing food, we should take a step back and define a few things. A typical FFF (Fused Filament Fabrication) or 3D printer is generally thought about as a 6080电影网 (Computer Numerical Control) programmable machine with three axes of motion and an extruder that deposits material in layers which fuse together to form a completed object. With that knowledge in mind, it’s easy to see how simple it is to convert a standard FDM 3D printer into a printer capable of extruding food. To 6080电影 my food printer, I used the Mingda D2 as a base.

The D2 has many features that work in its favor for this sort of experimentation: silent stepper drivers, a rigid frame and gantry, and an easily-accessible touchscreen make the D2 an easy choice. To convert this printer into a food printer, the only hardware change that needs to be made is to replace the heated extruder module that is designed for printing plastic with a system that is capable of extruding a paste.

Building the Paste Extruder Tool Head

After watching a video in which YouTuber constantjin shared his design process for creating a paste extruder, I decided it was finally time to give it a try myself. The overall motion system is fairly simple, with a threaded lead screw attached with a coupler to a stepper motor acting as the drive mechanism. A standard 60 ml syringe is attached to the body of the extruder and the plunger is replaced by a printed component with a rubber seal. When the stepper motor turns, the leadscrew rotates and causes the plunger mechanism to drop into the syringe, extruding the contents through the nozzle. In the video, constantjin did an excellent job of demonstrating the mechanical system, and I highly recommend watching it if you are interested in building one of his paste extruders for yourself. The frame of the paste extruder includes a 3×3 bolt pattern to attach to a mounting bracket, which I designed to attach to the Mingda D2. The stepper motors on the D2 proved easily capable of extruding peanut butter (a relatively thick paste), and I have no doubt that even thicker materials could have been used.

Generating Printable Patterns for 3D Printing Food

The first paste I used on the Mingda D2 food printer was frosting. It flows easily, holds its shape well, and is easily compressed into the syringe. I bought a few boxes of sugar cookies to test, and I was really happy with the results! Because I was printing directly onto these cookies; I needed to determine a few measurements so I could make sure my CAD file would be properly calibrated. I measured a dozen of the cookies and calculated the average diameter and thickness of the set, and used that as my starting point. To compensate for the thickness of the cookies, I set the Z-offset in PrusaSlicer by the measurement amount, which causes the toolpath to begin in mid-air. The diameter measurement was used to 6080电影 a single-layer cylinder with a 4mm thickness. By altering the infill patterns of this layer, I was able to 6080电影 several different shapes and styles of frosting on the cookie.

Printing a Peanut Butter and Jelly Sandwich

I’ve talked about printing a peanut butter and jelly sandwich for a long time, and having this paste extruder functioning finally allowed me to make this dream into a reality. Before printing, I expected the jelly to print without any issues while the peanut butter might be a challenge to extrude. I was really surprised with just how easy the peanut butter was to print; it flowed effortlessly and 6080电影d an even, consistent toolpath. Because I packed the peanut butter slowly into the syringe, I didn’t have a lot of air pockets and the toolpath was largely consistent.

Printing the jelly was a completely different story; it is so light and delicate that the slightest movement of the syringe caused it to eject from the nozzle, which makes packing the syringe and printing a challenge. To make the sandwich, I swapped between syringes and replaced the bread, creating two identical halves that could be folded together.

MP4: Andrew Sink

3D Printing Food in the Kitchen

Overall, the process of creating a syringe extruder for a 3D printer and making food has never been easier from a feasibility standpoint, and I think that it will likely become more commonplace in bakeries and kitchens to replace monotonous, repetitive tasks that could be performed by a robot or mechanical system. However, it is still an inherently messy and imprecise process when done with a homemade machine and I did run into issues with the toolhead not being aligned with the food it was supposed to be extruding onto. I only printed frosting, peanut butter, and jelly, but I believe that any food that can be squeezed through a nozzle is potentially a good candidate for being used in a 3D printing process.

If you’re interested in learning more, you can watch my 3D printed food video on YouTube to see my printer in action and see if this is a project that you want to replicate.

An Extra Toohead for 3D Printers

The pltr v1 was designed to work with the Anet ET4X and ET4. The Anet ET4X is a low-cost DIY kit printer that is ideal for modifying and the pltr v1 can be installed in under 10 minutes. I’m planning on creating more versions of the pltr in the future, including a version that can mount to the Creality Ender 3, the Creality CR-10, and others.

Pen Plotter – 10-min Installation

The installation process is quick, easy, and 100% reversible. To install the pltr, the hot end module is removed from the ET4X, the filament run-out sensor is disconnected, and the wiring harness is disconnected. Once they have been removed, the pltr can be installed using three flathead bolts. Calibrating the pltr is also quick and straight-forward, and involves moving the build surface with the pen attached to ensure the ink is distributed evenly across the writing surface.

DIY Kit and Fully Assembled Versions (Retired)

Currently, there are two versions of pltr v1 available on tindie: the Print-It-Yourself DIY kit and the Fully Assembled version. The DIY kit includes all of the mounting hardware as well as the printable files and is perfect for someone interested in printing the plotter bracket themselves to better understand the mechanical mechanism. The Fully Assembled version includes a printed and assembled plotter toolhead, all mounting hardware, and the printable files. This version is ideal for anyone who wants a more plug-and-play experience and wants to be plotting as soon as the pltr is out of the box!

pltr V2 Toolhead on GitHub

Originally launched as a product on Tindie, I’ve since decided to release all files for free on GitHub! If you still want to support this project, you can buy me a coffee on Ko-Fi!

Inkscape – Software for the Pen Plotter Art and Images

The software toolchain can be complex, and converting a raster image into something that can be plotted can require multiple software packages. Using Inkscape, I’ve been able to produce high quality plotted images from SVG files generated from within Inkscape as well as imported from other programs. Inkscape is an Open Source program with many plug-ins available that make plotting an easy process, and I highly recommend it when using the pltr.

3D Printed in GreenGate3D PETG

The pltr v1 is made using GreenGate3D ‘Slice Orange’ recycled PETG, which is a tough material that is ideal for functional mechanical parts like this spring-loaded bracket. GreenGate3D makes reliable, durable, and inexpensive material that is easy to use with a direct-drive printer such as the Prusa MK3S, which this plotter toolhead is printed on.

During designing stage, the bracket received an upgrade, acquiring more strength and depth to support the rail. What could be a wardrobe-replacement scenario ended up as a temporary inconvenience. All dresses were soon back in the wardrobe, neatly hanging and waiting for their turn to go out.

3D Printed Bracket for Wardrobe Rail

We had a lot of positive feedback on social media in regards to this quick fix. One 3D printing community follower on Facebook even asked for an STL file. At first, we thought that publishing an STL file would be pointless as this model was customized specifically for our wardrobe. However, after given it some thought, we decided to 6080电影 the instructions for its design and to publish it here.

Step 1: Measurements

Caliper: Of course, the first thing we did was take the measurements of the broken piece. By the way, calipher is one of the essential tools for both designing and 3D printing. Check the full list of essential, safety and optional 3D printing tools.

Step 2: 3D Designing in Tinkercad

It could be quite a lengthy exercise to describe every step in detail. Instead, we have put together a short video where the model is constructed out of basic blocks. Please pause when necessary. There was no need for a sketch prior to designing as the broken piece was right in front of us.

Step 3: Positioning in Simplify3D and PrusaSlicer

Simplify3D has an awesome function “Place Surface On Bed” (Place on Face in PrusaSlicer) that helped us to put the object on its side. We altered a few automatically generated supports to make sure there would be no problem with support removing and post-processing. Why should it be printed in this position?

Our model must be able to hold a massive weight, with the main tension directed at the side of the bracket. If printed upright, the layers would be placed in the same direction as the main tension from the rail. The end result can be prone to breaking. When the bracket is 3D printed on the side, with the layers placed continually in the direction, opposite to the tension point, it will strengthen the model.

We chose to print in rigid.ink ABS as ABS filament is stronger than PLA and this object has a serious task – to hold all valuables on the rail. In particularly this case, however, we think that PLA could work as well. Our item is twice bigger than the original and is quite strong. Even though an experienced eye may notice a low-poly texture of the object, the carefully chosen colour makes the end result look authentic.
