Use it as a quick planning tool before long prints and reduce the risk of running out of filament mid-job.

Filament Remaining Calculator

How It Works

The calculator estimates remaining filament by subtracting the empty spool weight from the total spool weight. It then uses filament diameter and material density to estimate how many meters of filament remain.

This is an estimate, not an exact measurement, but it is often accurate enough to help plan your next print.

How to Find Empty Filament Spool Weight

To calculate how much filament remains on a spool, you first need to know the weight of the empty spool itself. This is one of the biggest variables in any filament remaining calculator, as spool weights differ between manufacturers, spool sizes, and materials.

For example, a cardboard spool used by eco-focused brands may weigh significantly less than a reusable plastic spool. Some refill systems can also use heavier reusable spools that may affect your calculation if not accounted for correctly.

Here are the easiest ways to find your empty spool weight:

If you do not already have kitchen scales at home, a basic digital scale can make weighing filament spools much easier. Most 1kg filament spools fit comfortably on standard kitchen scales, and they can also be useful for resin, mixing materials, and general workshop tasks.

Recommended: Digital Kitchen 5kg/0.1g Scale on Amazon

• Check the filament label or packaging – some brands list empty spool weight
• Visit the manufacturer’s website or product page
• Search Google for “[Brand Name] empty spool weight” — Google AI may surface quick answers, but verify the result if possible
• Weigh an empty spool yourself using kitchen scales
• Use average spool weight estimates if no exact data is available

If you regularly print with the same brand, it may be worth saving empty spool weights in a simple note for future reference.

Typical Empty Filament Spool Weight Examples

These are rough averages based on common 1kg filament spools:

• Cardboard spool: approximately 120g–250g
• Plastic spool: approximately 200g–300g
• Reusable refill spool systems: approximately 250g–500g+
• Mini spools: vary heavily depending on brand and filament amount

To provide examples, we weighed several empty filament spool types used in our workshop. Your results may vary by brand, but these examples show how dramatically spool weights can differ.

Community contribution: Big thanks to Scuk for starting a catalog of more than 200 weighed empty filament spools on Printables. It’s a very helpful resource if you need a specific brand or spool type.

What to Print with a Nearly Empty Filament Spool

As mentioned earlier, lightweight prints are a great way to use up leftover filament. Models like Flexi Rex helped popularize the wave of articulated prints years ago, and today there are countless similar flexi models available across MakerWorld, Printables, and other STL platforms. Many of these designs require relatively small amounts of filament and are ideal when you are trying to finish a partially used spool.

Kit card models can be an even better option. These flat-packed designs are often extremely lightweight, quick to print, and easy to gift. Some are slim enough to fit inside a standard envelope, making them popular for events, giveaways, and seasonal gifts.

If you are looking for more ideas, explore our seasonal 3D printing guides in the 3D print ideas area, where we regularly feature lightweight gift ideas, decorations, and quick projects that work well with leftover filament.

Filament Connector

If your spool is running very low but still has usable filament left, filament splicing tools on Amazon can help combine leftover pieces instead of wasting them. This can be particularly useful for smaller prints, test models, or finishing nearly empty spools. We covered this topic in more detail in our Filament Connector: Filament Splicing Made Easy guide.

Common Mistakes When Estimating Remaining Filament

The most common mistake is forgetting to subtract the empty spool weight from the total spool weight. This can instantly throw off your estimate by 150–300g, depending on the brand and spool material. Another frequent issue is selecting the wrong filament diameter. While most hobby printers use 1.75mm filament, some machines still rely on 2.85mm material, and choosing the wrong option can significantly affect the estimated filament length.

It is also worth remembering that not all filament brands use identical spool designs. Cardboard spools, reusable refill systems, and heavier plastic reels can all produce different results. Even if your calculation looks accurate, avoid starting very large or multi-day prints with very little filament left. Your slicer remains the best source for exact filament usage estimates, so use this calculator as a planning tool rather than a guarantee.

If you are close to running out, consider switching to a fresh spool or enabling filament runout sensors if your printer supports them. It is far better to swap filament early than lose a long print near completion.

Why Filament Type Affects Your Results

Different filament materials have different densities, which means the same spool weight can translate into different filament lengths. This is why our calculator asks you to select a material type before generating an estimate. A 200g remainder of PLA may not provide the exact same number of printable meters as 200g of ABS, TPU, PETG, or Nylon.

PLA and PETG are among the most commonly used materials for everyday prints, while TPU is often used for flexible parts and Nylon is typically chosen for more demanding functional applications. ABS remains popular for certain workshop and engineering projects. Because each material behaves differently in both weight and print settings, your slicer may still show slightly different filament usage depending on layer height, infill percentage, wall thickness, and support structures.

For the most accurate planning, use this calculator as a quick estimate and then confirm the final filament requirement inside your slicer before starting longer prints.

What are Creality M1 and R1?

The system consists of two separate units that work together. The Shredder R1 is designed to process properly prepared 3D printing waste into reusable material. The Filament Maker M1 then mixes, extrudes, and spools filament for future use.

Rather than presenting this as a fully automated one-click recycling solution, the idea seems to be much more hands-on. Creality is positioning the setup as a compact desktop workflow for users who want to experiment, refine materials, and better understand what goes into filament production.

How the System Works

In simple terms, the R1 handles waste preparation, while the M1 focuses on filament creation. Together, they bring several normally separate steps of material reuse into a more compact maker-oriented setup.

According to the press release and demo video from YouTube, the workflow is intended to support material reuse, small-batch production, color and additive experimentation, and greater control over print outcomes. That makes it less about mass production and more about giving advanced users a chance to test, tweak, and good电影在线观看 filament in-house.

Why It Is Interesting

What makes this launch stand out is not just the hardware itself, but the direction behind it. Desktop 3D printing has become more accessible over the years, but filament itself has remained mostly fixed as a bought-in material. Creality is now exploring the next step, where users do not just print objects, but also shape the material they print with.

For makers, schools, labs, and workshops, this could open up several interesting possibilities. It may help reduce material waste, lower long-term filament costs in some scenarios, and encourage more experimentation with blends, colors, and additives. It also adds an educational angle, as users can better understand the full material cycle behind desktop 3D printing.

Who It May Suit

At this stage, Creality M1 and R1 look most relevant to hands-on users who enjoy testing new workflows, rather than to those looking for the simplest plug-and-play setup. This could include experienced makers, educational environments, small workshops, content creators, and anyone interested in recycling and material development within desktop 3D printing.

It will also likely appeal to users who already generate a lot of printing waste and want to explore whether part of that material can be reused in a practical way. As with many first-generation systems, the real value will probably come from experimentation, process refinement, and seeing how well the workflow performs in everyday use.

About Creality

Creality is one of the best-known brands in desktop 3D printing, with a product range that now stretches far beyond entry-level machines. Over the years, the company has expanded into resin 3D printers, laser engraving systems, scanners, and broader maker-focused tools, building an ecosystem that serves hobbyists, educators, and more advanced users alike. Its products are widely recognised for making digital manufacturing more accessible to a wider audience.

Creality products can also be seen regularly at major industry events, either on the company’s own stand or through local resellers and distribution partners. The Filament Maker M1, for example, was already being shown at TCT Asia 2026, suggesting that this new recycling system is already part of Creality’s wider product tour and public showcase strategy.

Many makers will know Creality through products such as the Ender 3 series and the CR-30 belt printer, both of which helped push new ideas into the desktop 3D printing space. On good电影在线观看, we have hands-on tested and featured many Creality products over the years, from printers to 3D scanners and laser cutters. You can browse more of our Creality coverage here: Creality articles on good电影在线观看.

Launch and Availability

Creality has launched the Filament Maker M1 and Shredder R1 through an Indiegogo campaign, with early access pricing mentioned for first backers. As this is intended to be an evergreen launch article, this section can be updated later with retail pricing, shipping progress, hands-on testing, or newer versions such as M2 or R2.

Creality Filament Maker M1 and Shredder R1 on Indiegogo

Final Thoughts

With M1 and R1, Creality is entering a part of the 3D printing workflow that has often been discussed but rarely packaged for desktop users in such a direct way. Instead of focusing only on faster printing or larger build volume, this launch shifts attention toward material reuse, experimentation, and control.

If Creality continues building this category in the future, this could become more than a one-off launch. It may grow into a wider ecosystem around desktop filament production and recycling, giving makers new ways to reduce waste and get more involved in the materials behind their prints.

Jayo FilaDryer J1 Specifications

What’s in the Box

J1 FilaDryer Set: The standard package includes the drying chamber, heating base, desiccant pack, desiccant container, bottom rollers, bottom bearings, filament holder, sealing footpads, a 1 m PTFE tube, user manual, and power cable.

J1 FilaDryer Bundle Set: The bundle version includes the drying chamber, desiccant pack, desiccant container, bottom rollers, bottom bearings, filament holder, sealing footpads, PTFE tube, and user manual.

Initial Overview

One of the standout aspects of the Jayo J1 FilaDryer is its thoughtful, modular design. Each drying chamber is fully stackable, allowing users to expand their setup as their filament collection grows. Whether you are running a print farm or simply juggling multiple materials at home, the ability to build upward instead of outward keeps your workspace clean and efficient.

Despite its compact footprint, the J1 supports a wide range of spool sizes, from lightweight 0.25 kg spools to standard 0.5 kg and 1.1 kg rolls, including paper-core spools. A cross-axis support system keeps the spool stable, while the integrated hygrometer provides a quick visual check of humidity inside the chamber.

Drying performance is handled by a 150 W PTC heating system that can reach up to 70°C, targeting consistent heat delivery for a broad range of filaments. An internal hygrometer helps you track humidity during a drying cycle, and the storage mode is designed to keep filament protected between prints.

Setup Process

The Jayo J1 FilaDryer arrives with everything you need to get started. Inside the box, you will find the main drying unit, a storage chamber, a combined hygrometer and desiccant module, and a small set of parts for the spool rollers.

Begin by assembling the two bottom rollers and their bearings. Slide a bearing onto each end of the rollers, then seat the rollers into the lower section of the storage unit.

Next, insert the hygrometer module into the front of the storage box (the section with the clear display window). It slides into place and also houses the desiccant container.

Place the desiccant pack into its container. The included desiccant changes colour as it absorbs moisture, which makes it easy to see when it has been working and when it may need recharging or replacement.

Finally, install the filament holder into the centre section of the unit so the spool is supported correctly during drying and printing.

Once assembled, the dryer can be used as a standalone drying station or as a feed-through dryer while printing. The heating base houses the controls for temperature and timer settings.

In everyday use, the controls are simple and responsive, making it easy to dial in the right drying settings without overthinking the process. It is a straightforward system that does exactly what it is designed to do.

Stackable Storage Capabilities

One of the most useful aspects of the Jayo J1 FilaDryer is its stackable storage design. Each unit is shaped to sit neatly on top of another, allowing you to expand capacity without taking up extra bench space. Jayo recommends stacking up to three units high, which is ideal for anyone managing multiple filament types or running several printers at once.

Even when stacked, the front-mounted hygrometers remain visible, making it easy to check humidity across chambers at a glance. One downside is that there is no physical latch between units, so you will want to keep the stack on a stable surface.

Safety and Thermal Cutoff

The Jayo J1 includes thermal protection designed to reduce risk during longer drying sessions. The unit incorporates a hardware-level thermal cutoff intended to shut down heating if temperatures exceed safe operating limits, acting independently of the software control system.

Removable Bottom Covers

The J1 uses removable bottom covers for drying and storage modes, each with a rubber seal to help maintain an airtight closure. It is a simple design choice, but it supports the main goal: keeping filament dry during storage, not just during a heated cycle.

Testing (Wood PLA Benchy)

Wood-based PLA blends are extremely prone to absorbing moisture, far more than standard PLA. When they take on water, steam pockets form during extrusion, causing bubbling, stringing, and rough surface texture. Proper drying is the quickest way to bring print quality back under control.

To demonstrate the impact, I printed two identical Benchies using the same gcode. The first print was done straight from the spool without drying. The second was printed after drying the filament for six hours in the Jayo J1, then storing it in the sealed chamber to reduce reabsorption.

Following the six-hour drying cycle, the humidity reading dropped significantly, and the print quality improved with fewer visible artefacts, smoother surfaces, and more consistent extrusion.

Video: JAYO FilaDryer J1 in Action

Alongside this written hands-on review, I also recorded a detailed video showing the JAYO FilaDryer J1 setup, drying process, and real-world testing with filament prints. The video gives a closer look at the unit’s design, controls, and how it performs during everyday use.

Other Filament Dryers

On good电影在线观看, we have a detailed filament dryer comparison guide where products from brands such as EIBOS, Creality, Polymaker, Sovol, and others are listed for price and feature comparisons.

• SUNLU FilaDryer S4 (Review)
• Polymaker PolyDryer (Review)
• SUNLU FilaDryer E2 (Review)

Other filament dryers, such as the SUNLU S1, are built around higher capacity, supporting dual spools or larger 3 kg rolls. In contrast, the Jayo J1 adopts a slimmer, single-spool design with stackable expansion, making it better suited to compact workspaces where footprint matters more than volume.

The Jayo J1 would pair well with the wide range of FDM 3D printers we’ve thoroughly tested over the years, particularly in budget and mid-range categories where filament consistency makes a noticeable difference.

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 亚洲三级+日韩欧美 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.

4) Connect USB-C cables: Plug in the labeled cables — power module to rear, screen module to front, and heating station leads routed through the outer channels.

5) Attach modules: Secure the power module to the rear and the screen module to the front brackets using M3 H10 screws. Confirm no cables are pinched and all connections are firm.

6) Final connections: Complete all USB-C wiring: screens to front, power to rear, and long leads to heating stations.

Acrylic Baffles and Seals

7) Attach rubber feet: Place 4 on the front and 4 on the rear module brackets.

8) Assemble front baffle set: Clip the acrylic parts in this sequence: A (left), B, B (center), C (right).

9) Insert assembled baffles: Fit into their corresponding slots as per diagram.

10) Install middle baffles: Use the acrylic fixings to insert in the order: B, A, B.

11) Secure rear baffles: These lock in the acrylic housing. Fit them gently — do not force.

12) Apply gasket: Add the silicone strip between the upper and lower housing to complete the chamber seal.

The fully assembled unit should now resemble the product demo images, ready for connection to the printer.

Operating the Dryer

– Screen Layout / Settings
The display screen is much like previous Eibos dryer models and is easy to use with the simple layout.

Before powering on, it’s worth checking the voltage label on the back of the unit to ensure it matches your region’s standard safety requirements.

Once connected, a single press of the power button brings the dryer online. You can toggle between drying-only and humidity-controlled modes depending on your needs. There’s also a factory reset option, but I never had to use it.

Filament types, such as PLA, ABS, PETG, and TPU, can be selected via the Option button. Each preset automatically loads the ideal drying parameters, but you can override them if necessary. I liked that the system remembers custom material profiles (M1 and M2), which is useful if you frequently switch between brands or experimental filaments.

Using the Setting button, you can cycle through key parameters:
Drying temperature (20°C – 65°C)
Drying time (30 minutes – 24 hours)
Power level (Low / Medium / High)
An optional humidity threshold if you’re using it in “smart” mode

One handy feature is the Second-Stage Drying Mode. I didn’t use it every time, but when drying filaments that had been sitting unsealed for weeks, it came in useful. It’s activated through the dedicated button and offers the same level of control as the primary cycle.

For me, the screens were responsive and easy to understand. The segmented layout clearly displays set temperature, live temp, humidity, and time remaining — all at a glance.

– Automatic Sealing Cover Operation
During the drying function, the sealing cover will automatically open and remain in an open Position. Once drying is complete, the cover automatically closes and maintains the sealing condition of the chamber. In the event of a sudden power loss or external interference that causes the cover to fall or remain open, you can manually adjust it.

In use Operation

Once the assembly was complete, I mounted the Tetras unit on top of my Bambu Lab X1C, in its usual position. What stood out immediately was how seamlessly it fit in: the overall look and functionality of the setup remained unchanged. I connected the familiar PTFE tube and cables, with the only notable difference being the need for a second power socket. That said, having the ability to actively dry filament during printing is a huge win. It felt like a natural upgrade rather than a workaround.

Over the following days, I ran a range of prints using both new and previously opened filaments. Selecting the correct material profile on the Tetras was quick, and the drying cycles could be adjusted based on condition and time. One standout feature was the option to run just one filament bay at a time, which is perfect for saving power. Whether printing single-color objects or pushing multicolor jobs at high speeds, I noticed a clear boost in print quality. Overall, the Tetras integrated seamlessly into my workflow, making them feel like they had always been part of the AMS.

Sample Projects

Model 1: Happy Sitting Pot Horns
I printed this model in dual color using filament that had been left unsealed for several weeks. A perfect test for the Tetras’ drying capability. I preheated the Series X Tetras for 2 hours before starting the print and kept it running throughout the job, with a total drying time of around 6 hours.

The model I chose was the Happy Sitting Pot Horns Hand by TomoDesigns on MakerWorld. It was printed at 0.2 mm layer height using two color variants. Despite the filament’s exposure to ambient air, the result came out clean and consistent, showing that the drying system really makes a difference.

Model 2: Pencil Holder
This model was preloaded on the SD card of the Bambu Lab X1C, and since my wife needed a pencil holder, it was the perfect choice. I printed it in a single color to see how the Series X Tetras would perform in a basic single-bay scenario. I set the dryer to run for about 6.5 hours to cover the full print duration, and when I checked back, it had shut off exactly as scheduled. Simple, effective, and spot on for everyday use.

Model 3: Rock People by Blob Lab
I printed the Rock People models by Blob Lab, found on Patreon, using multi-color filament. Each one was printed individually due to the nature of the design, and I ended up completing over a dozen of them. In the past, I’ve had issues with damp filament causing failed prints, especially on detailed models like these.

For this run, I used all four filament slots on the Tetras and dried the spools for about six hours before printing. The results were noticeably more consistent.

Temperature Accuracy

I carried out temperature performance tests on each bay to compare the readings from the unit’s display with an external temperature sensor. All readings were within 0.5°C of each other, confirming that the Tetras is delivering consistent heat. You can see an example of this test in the image below.

The temperature ramped up quickly after entering the settings and reached the target range within the expected timeframe. Airflow across the chambers was even and steady, contributing to a reliable drying environment.

Comparison: Other Filament Dryers

On good电影在线观看, we maintain a comprehensive filament dryer comparison guide, covering various models across brands like EIBOS, Creality, SUNLU, Polymaker, and Sovol. These products differ by capacity, drying method, and intended use — from single-spool casual solutions to multi-bay systems for professional workflows.

The EIBOS Series X Tetras stands out by integrating directly with the Bambu Lab AMS, offering active drying across four individual filament bays. Unlike standalone dryers, the Tetras is designed as an upgrade module and doesn’t require additional handling or spool transfer once installed.

Other options such as the EIBOS Polyphemus support two spools or a single 3KG roll.

In summary, while most dryers cater to consumer-level needs, the Tetras is unique in its ability to retrofit and elevate existing multicolor printing systems like the AMS, bridging a gap between convenience and production-grade consistency.

Conclusion and Key Takeaways

The EIBOS Series X Tetras is a well-thought-out upgrade for users already running a Bambu Lab AMS. Instead of adding yet another standalone dryer to your setup, the Tetras integrates directly with your existing system, offering independent drying bays without compromising on space or performance. The kit comes well-packaged with all components neatly labeled, and the step-by-step assembly process is straightforward even for users new to hardware modifications.

What stands out most is the ability to enhance print quality without needing to buy a new filament or overhaul your workflow. Each bay operates independently with its own screen and settings, allowing for efficient filament management across multicolor prints. From setup to performance, the system worked reliably throughout testing. While the current configuration uses four separate control panels, there’s potential for future refinements such as a unified touchscreen interface or smart connectivity.

Pros
• Easy to assemble and operate
• Independent heated chambers for each filament bay
• Strong overall build quality
• Seamless integration with Bambu Lab AMS
• Quick heating response

Cons
• Uses four separate screens — a single touchscreen could reduce clutter and offer future expandability

What’s in the Box

Base + 1 Box Package Includes:
Drying Chamber, Heating Base, Hygrometer, Desiccant, Desiccant Box, Power Cable, Spool Roller, Air Lock x2, PTFE Tube (8cm ×2, 1m ×2), User Manual.

Here is the Base + 1 Box and 1 Box + 2 Spools Package:

My FilaDryer SP2 arrived in a package including one Base, 2× Boxes, and 2× Spools (approximate value: $173). The two filament spools were securely packed in the second box. I’m not sure if this bundle will be available later, but it makes sense and is cost-effective in terms of transportation.

Features & Design

SP2 stands for Smart Printing, 2 for modular design.
SUNLU has followed the trend by releasing their own modular filament dryer. This system not only dries the filament but also serves as effective storage and can be convenient for transportation. I’m not sure if it was intentional, but the ability to stack the boxes on top of each other is also space-saving.

– Airtight. Compared to SUNLU’s other filament dryers, the S2 and FilaDryer S4, the SP2 stands out for being airtight. The top lid closes very securely, and the bottom plugs are lined with rubber around the perimeter to ensure a tight seal.

– Temperature. As promised, it maintains 70°C at the maximum setting. As shown on my infrared camera, the heating element itself reaches around 80°C, while the spools heat up to approximately 70°C. This temperature is sufficient for drying popular materials like PLA and is suitable for storing engineering-grade filaments such as PA (Nylon) and CF (Carbon Fiber blends). For drying and even annealing engineering-grade materials, the FilaDryer E2 is more appropriate, as it can reach temperatures up to 110°C.

A TopDon thermal camera offers a visual view of the overall heat distribution. You can see the thermal camera view in our short YouTube video.

– Touch Screen. The detailed touchscreen allows you to select preset programs for common filaments like PLA, ABS, PETG, and more, with the option to adjust settings as needed. The green LED light strip can also be customized for added visual appeal. It looks spectacular in a dark room.

Testing and Setups

To learn why filament should be dry, how filament dryers help, and to read more about hygroscopicity, check out our detailed guide.

– Teflon Tubes. As the instructions suggest, PTFE tubes should be installed, especially when there’s a sharp curve in the filament path. I used the FilaDryer SP2 while printing DeathRacer side panels on the Snapmaker Artisan, using extra-long PTFE tubes (not the ones included). These tubes were 110 cm in length. The included PTFE tubes are one meter.

This setup worked very well. Humidity remained at 20% even after a few days, when I printed the second side panel. I didn’t need to dismantle the heating base and assemble the bottom plug panels for that lengthy pause. Despite the dryer being positioned some distance away from the printer, there was no noticeable resistance that interfered with printing.

Here’s an example of the SUNLU FilaDryer SP2 feeding filament to the Creality K1 without a PTFE tube. It worked well with PLA, even with a slight curve in the filament path.

– Noise. Here are the decibel meter readings with the lid on and off. Devices like this naturally produce some noise during operation. In comparison to the FilaDryer S4, which measured 59 dB (lid on) and 73 dB (lid off), the SP2 is noticeably quieter, thanks to its airtight design.

– Open/Closed Plugs. Just a quick reminder: when the heating base is ON, it’s important to keep the side filament plugs open to allow warm, humid air to escape. Once drying is complete, close the plugs for storage. This method makes it easy to reach and maintain a humidity level of 15–20%.

Other Filament Dryers

On good电影在线观看, we have a detailed filament dryer comparison guide where products from brands such as EIBOS, Creality, Polymaker, Sovol, and others are listed for price and feature comparisons.

• SUNLU FilaDryer S4 (Review)
• Polymaker PolyDryer (Review)
• SUNLU FilaDryer E2 (Review)

Other filament dryers, such as the EIBOS Polyphemus, are also designed to hold two spools or a single 3KG filament spool. PolyMaker’s PolyDryers also offer an integrated storage solution with their PolyDryer Box. In comparison, the SUNLU FilaDryer SP2 offer airtight modular storage solution for different spool sizes.

In comparison with other SUNLU FilaDryers, S2, S4, and E2. While the S2, S,4 and now SP2 are suitable for consumer-grade filaments, the E2 is designed for engineering-grade filaments and includes an additional annealing function.

Unboxing and Design

My FilaDryer E2 arrived in a bigger box than usual, as it included an extra eight filament spools. I was informed that my device comes with the first batch of machines and that there will be some product optimizations where needed.

– What’s in the Box. The package should include the power cord, PTFE tubes, annealing tray, and heat-resistant gloves. However, the gloves were missing from my batch. I must say that gloves are essential for quickly handling spools and prints without waiting for them to cool down, as some spools become too hot to handle safely.

– Damaged During Handling/Transportation. Upon close inspection, I noticed that my FilaDryer E2 is damaged: one of its feet is pushed in. I have already contacted the SUNLU team to provide feedback, helping them address the issue and add extra protection or reinforcements where necessary.

To ensure that no electronics were damaged, I removed the bottom lid to inspect the device. Given that this is a high-temperature device with sensitive electronics, it’s always better to be cautious. To my relief, the area where the legs were pushed in contained no electronics. If the impact had occurred on the electronics side, there could have been potential rubbing against the wires.

– Design. Like the other devices in the SUNLU FilaDryer family (S4 and S1), the FilaDryer E2 has a sleek, transparent design with a bright green LED indicator that stops moving and lights up once the chamber reaches the assigned temperature.

– Airtight. Compared to the S4 and S1, the E2 is the most airtight, thanks to its rubber plugs and sealed lid. According to the manufacturer, placing a desiccant dehumidifier in the designated area allows it to function as a storage dry box. Another benefit of sealing is that the operating fans are less noisy.

– Touchscreen. The E2 touchscreen may not match the quality of those on newer generation 3D printers. But, it still allows for easy navigation through functions and complements the overall design of the FilaDryer series. All presets and settings were straightforward to adjust using the [SET] button along with the up and down buttons.

– RH 10%. The only aspect I couldn’t understand and wished was more precise is the humidity reader, which was always at RH 10%. However, the SUNLU site provided an explanation: If the product set working temperature ≥ 80 ℃, humidity detection module will be in a protective state (display humidity RH 10%) is a normal phenomenon when the drying box temperature is reduced to 70 ℃, about 20H, humidity detection module automatically restore the original precision.

– Instructions. The included operation instructions are quite handy. I got a quick sneak peek at the annealing mode settings directly from them. They also include helpful tips, such as: ‘For optimal drying, keep the silicone plug open during drying.’

– Safety. Safety is paramount with this 500W heating device, as high temperatures can rise quickly. According to the manufacturer, an alarm will sound, and heating will stop if temperatures become abnormally high. In my own tests outside the enclosure, temperature readings stayed within acceptable ranges. Needless to say, the device is made from fire-resistant materials. While I can’t offer a comprehensive assessment yet, after several hours of use, external temperatures remained within normal limits. See the thermal footage below.

Drying Mode

In our previous guides, we thoroughly explained the importance of keeping filaments dry and using filament dryers. To put it briefly, it’s essential for improving the quality of 3D prints.

One of the main features of the SUNLU FilaDryer E2 is its high-speed heating and higher drying temperature limits. By pressing [SET], you can cycle through the preset filament drying modes, such as PA(Nylon), CF(Carbon Fiber), ABS, and others.

As a quick test, I started a print on the Creality K1 using SUNLU’s Easy PA(Nylon) filament. While the model I chose wasn’t intended for engineering purposes, it produced an interesting result.

I was pleased to see the Creality K1 pull the filament smoothly without extra PTFE tubes despite entering the 3D printer at nearly a horizontal angle.

While the PA(Nylon) setting heated the chamber to 100°C (212°F), readings from an infrared thermometer revealed temperature variations across different areas, as hot air flowed in a counterclockwise loop from right to left.

Another device, a TopDon thermal camera, offered a more visual view of the overall heat distribution. You can see the live thermal camera view in our short YouTube video featuring SUNLU FilaDryers.

The functional, themed sticky note holder printed very well in Easy-PA (Nylon) with a nozzle temperature of 270°C and a heated bed at 80°C. However, upon cooling, the thin wall in the holder area bent quickly. The print would have failed if it hadn’t been placed in the chamber for post-processing in annealing mode. See images below.

Annealing Mode

Annealing in 3D printing means heating a printed part below its melting point to relieve stress, improve stability, and enhance its properties.

I had a great example of a model that printed well in regular and exotic PLAs but showed an interesting bend in the holding area when printed in Easy-PA. I must admit I hadn’t used this material before, so there might be specific cooling settings to avoid this issue. Nevertheless, it was perfect for my task. I tested E2 annealing mode right on this model to see if it could fix the problem.

Annealing mode presets on the E2 range between 2 to 6 hours and temperatures of 80°C (176°F) to 100°C (212°F). In my case, I left my print in the chamber for about 10 minutes, during which it became soft and flexible. I could then carefully ‘massage’ the bent area back into its designed position, significantly improving the bend.

Physically manipulating different types of plastics is possible with a heat gun, but the results are often uneven. One side of the printed part might even get damaged before the other side has fully warmed up. In contrast, an annealing chamber ensures the entire model is heated evenly.

As a fun test, I placed a Benchy printed in white PLA into the chamber, and within about ten minutes, it became soft enough to squeeze with just two fingers. Poor Benchys – I have a feeling many more will become test “victims” of this device!

Importance of the Teflon Tubes and Setups

As instructions suggest, the Teflon tubes should be installed, especially if there is a sharp filament travel curve.

In my previous FilaDryer S4 review, I tested various setups with different printers and positions. However, the PTFE tubes provided with the E2 are quite short. I would recommend that SUNLU include longer PTFE tubes or offer custom-length options as an add-on for a more sustainable solution. For reference, here’s an example of the FilaDryer S4 setup on the Snapmaker Artisan.

The two PTFE tubes feeding filament to the Snapmaker dual extruder are over a meter long. When using such long tubes, it is important to use high-quality filaments with consistent diameters. Additionally, it’s a good practice to check for excessive filament feeding resistance. My XYZ Cube test print was completed without issues, as shown in a short YouTube video.

I like this setup and would love to have custom brackets to hold the S4 on top of the Artisan enclosure. Placing the E2 on the enclosure feels excessive and would complicate the use of the annealing mode.

Other Tests

As my SUNLU FilaDryer E2 testing continues, I’ve geared up with some very interesting engineering-grade filaments from SUNLU, including Easy-PA, PC-ABS, PA6-CF, and PA12-CF. I’ve also prepared filaments from Inslogic, such as ASA, PETG Pro, TPU 95A, and Matte PLA. Additionally, my shelves still hold ABS, PETG, and a variety of PLA. Slowly but steadily, I will cover these materials in various reviews and add the results here. If you’d like me to test annealing or drying with specific materials or prints, please share the details in the comments below. I may speed up the process…

No more invading the kitchen! Using the E2, I dried loose desiccant and sachets for approximately 30 minutes on full power. While it can be done faster in a regular microwave on defrost mode, having the option to do it in the workshop is both convenient and peaceful.

Other Filament Dryers

On good电影在线观看, we have a detailed filament dryer comparison guide where products from brands such as EIBOS, Creality, Eryone, Sovol, and others are listed for price and feature comparisons.

• SUNLU FilaDryer S4 (Review)
• Polymaker PolyDryer (Review)
• Filament Drying Solutions for Snapmaker 3D Printers (Guide)

Other filament dryers, such as the EIBOS Polyphemus and FIXDRY, are also designed to hold two spools or a single 3KG filament spool. PolyMaker’s PolyDryers offer a convenient, integrated storage solution with their PolyDryer Box.

In comparison, the SUNLU FilaDryer E2 belongs to a different, engineering-grade category, standing out as a two-in-one device that combines a high-temperature airtight filament dryer with an annealing feature.

The comparison with other SUNLU FilaDryers, S2 and S4, is covered in detail in this guide. While the S2 and S4 are suitable for consumer-grade filaments, the E2 is designed for engineering-grade filaments and includes an additional annealing function.

To evaluate this filament, I chose to print large and challenging models. When using rainbow filaments, achieving the desired colour transition greatly depends on the model’s size. I printed three models in varying sizes. As you can observe, smaller objects show minimal colour transition, whereas larger objects display the full spectrum of the transition more prominently.

The Moon City model by Kijai Designs turned out exceptionally well with this filament. The filament’s qualities perfectly complement the striking design of the model. The model looks stunning in silk PLA, and I believe it would also look equally impressive in matte PLA. This particular print was made on the Creality K1 Max.

Next, I printed a Voronoi Skull by Joker3D on MakerWorld, which also turned out great. Printing in Voronoi style is challenging for both the filament and the printer due to the complex design. Printing models in this style involve numerous retractions, extensive bridging, and precise cooling, all of which challenge the capabilities of desktop 3D printers.

The last object I printed with this filament is the ‘Print in Place Helicopter Toy’ by Triple G Workshop, available on Printables. As I mentioned before, the colour transition is not noticeable due to the model’s small size. This is an interesting model that is printed upside down. The model came out very well, without stringing or other issues, on the Creality K1 Max.

Conjure Matte Rainbow PLA and Test Prints

Amazon

Official Website

Like any other rainbow filament, Matte Rainbow PLA filament is made to good电影在线观看 colourful transitions. Conjure’s Matte Rainbow PLA filament consists of gorgeous pastel shades. This filament can be used for both large prints to see the transitions more prominently or for small objects separately. 3D prints almost always look great in pastel colours.

As you can see, the T-Rex Skull by STLFlix features color-rich transitions. Thanks to the design and printing requirements, the area where the skull connects has the same, light blue matte color shade. Have a look at the stand; it also came out well and showcases the color transition. T-Rex Skull printed on the Creality Ender-3 V3 Plus that I recently reviewed.

The popular flexible articulated Pokémon Charizard model by IXPatch is another challenging model that both the filament and 3D printer handle well. All flexible articulated models require special attention to bed adhesion, retraction, and cooling settings. Few budget 3D printers can do it right without extra 3D printer tuning. This model came out well on my Creality Ender 3 V3 Plus.

Other Conjure Filaments

Here are other Conjure filaments I would recommend investigating.

Conjure Chameleon

Amazon

Official Website

This filament is supposed to change shade with light and angle. Upon closer examination of other people’s makes, it resembles sparkly PLA. It’s made with a similar concept to Marble PLA, galaxy blue or black PLA.

Conjure High-Speed PLA+:

Amazon

Official Website

High-Speed PLA+ is an innovative addition tailored for those prioritising efficiency and speed. This filament is designed to withstand higher printing speeds without compromising the quality of the print. High-Speed PLA+ ensures that time efficiency matches top-notch print fidelity, making it a go-to choice for businesses and fast-paced creators.

Here is the print in Conjure High-Speed PLA+ that was earlier featured on this website. Max batch printed Post-It Note Holders when reviewing the Elegoo Neptune Max 4. High-speed PLA is becoming the new normal, a standard, as most printers have become faster.

Max also printed a Redwood Giant Tree Trunk Vase in Spiralize Outer Contour mode to showcase the machine’s large build volume. This is an example of the other filament colors and shades that Chitu Systems offers with its Conjure filament brand.

Conclusion and Pros & Cons

PROS:

Quality
CONS:
Spools made of plastics for some of the filaments

I hope my guide has demonstrated the possibilities when printing with high-quality Conjure filaments. Beyond maintaining and updating their CHITUBOX slicer software, Chitu Systems has excelled in supplying top-notch resin and FDM 3D printing materials. Additionally, the pricing is quite attractive. The resin and filament can be affordably purchased through their website and Amazon pages.

Why are Filament Dryers Needed?

Until now, we used to keep all filaments in sealed plastic bags with a piece of a desiccant dehumidifier and were generally happy about it. Of course, in a few years, filament quality in some spools became degraded due to general mishandling. Plastic bags either didn’t get sealed properly, were micro-pierced by a sharp filament end, or the silica gel stopped working, and we had no idea about it.

In extreme cases, our filament made a popping noise during extrusion, and some visible evaporation occurred. This is the source of uneven surfaces on the prints. When the water is heated, it boils and evaporates, leaving micro craters on the extruded filament and printed surfaces.

The opportunity to reverse the process and get the quality of the material back is very welcoming. This is where filament dryers may come to the rescue.

Moisture Absorption – Hygroscopicity

In our previous article, “How to Revert Filament Moisture Absorption,” Curry Lin explained how it works in detail. He even featured a chart showcasing how some filaments are more hygroscopic than others.

He also listed filament drying methods and differences, including using desiccant dehumidifiers only, PI heating pads, and enclosed filament dryers, and he listed the pros and cons of each technique.

The Best Filament Dryers

Here, we will list the best filament dryers available on the consumer market for FDM 3D printers. Some are more expensive and sophisticated, while others are best for space and budget.

SUNLU S2 Filament Dryer

Price: $44-54
Product links:
Amazon | AliExpress | Official Website

This is the second filament dryer from SUNLU, the S2, which stands out with its futuristic look. It has a compact build and a large touchscreen display, and it presents many metrics, including temperature, moisture, target temperature, timer, and material type. The settings are easy to see and use. With a maximum temperature that can be increased up to 70°C, the S2 can now dry a wider range of materials, such as PLA, ABS, Nylon, and more.

This build enables the filament to be fed to our Creality 3D printers. For the Ender 3 V2 Neo, the filament feed is straightforward and even safer than using the original spool holder on the top. It eliminates the risk of brittle filament snapping. The Ender 5 S1 also works well with this setup, even though its filament feeding mechanism is slightly unusual. Refer to the Ender 5 S1 review article for more details.

360° Heating: The heating element now wraps around the spool much more evenly, unlike the previous version, which covered only around half of the spool area. As the SUNLU S2 is designed as an active heated filament dryer rather than an airtight dry storage box, it does not include a dedicated desiccant compartment. This keeps the setup simple, with no desiccant bags to monitor or replace. However, for longer-term storage after drying, an airtight storage box with dessicant bags or vacuum-sealed storage bags is still recommended.

SUNLU, a well-established name in the 3D printing industry, has expanded its lineup with the FilaDryer SP2. It’s an airtight, modular system designed to store and dry filament more efficiently, capable of accommodating two 1kg spools, or one 2kg or 3kg spool.

The FilaDryer SP2 is SUNLU’s answer to a modular, airtight storage and drying solution. I’ve used the device extensively and have been pleased with its performance. The storage boxes are relatively large – designed to accommodate spools up to 3 kg, as well as standard 1 kg spools. Any remaining space can be effectively used for extra desiccant bags to enhance drying and humidity control.

SUNLU keeps bringing filament maintenance solutions to the market. Their latest product, the SUNLU FilaDryer S4 filament dryer, can accommodate and dry up to four 1kg spools at once.

Generally, I am pleased to have FilaDryer along with my FDM 3D Printers. Over the years, I’ve accumulated a lot of half-empty spools that have lost their quality due to humidity. Now I can refresh them four spools at once. It is definitely a good device for FDM 3D printer workshops. Also, it can be a fancy alternative to a filament storage box for casual 3D printer users as well.

Polymaker’s PolyDryer was co-developed and beta-tested with the help of some members of the 3D printing community.

I was impressed by the PolyDryer and would not hesitate to recommend it as a useful tool that can pay for itself quickly. The PolyDryer is an easy purchase to justify for print farms as well as hobbyists who just want to prepare their material immediately before printing. The modular PolyDryer Box system can be used to store material between uses, and the visual indicator of the hygrometer on the front of the unit gives an at-a-glance status update on the condition of the material.

I especially appreciated the airtight separate chambers. As shown in the image, one chamber can dry PLA at 50 °C while another handles TPU at 60 °C, each tailored to the material’s needs. What’s more, the system allows you to leave filaments inside and check the humidity levels the next time before starting a new print. This adds both reliability and convenience for anyone working with sensitive engineering-grade filaments.

The Jayo J1 FilaDryer delivers an impressive balance of performance and affordability, coming from $59.99. For a dryer at this price point, it offers a surprisingly capable feature set. It handles all the usual suspects, including PLA, PETG, ABS/ASA, and TPU, and even takes on moisture-sensitive materials like PVA and nylon, which is where many budget dryers start to struggle.

The Jayo J1 FilaDryer is a practical and effective solution for makers who want consistent filament performance without spending a fortune.

Sovol SH01 Filament Dryer Box

Price: $37-59
Product links:
Amazon | AliExpress | Official Website

FDM 3D printer manufacturer Sovol offered their own version of a filament dryer. This product can hold two spools at a time and displays both temperature and humidity levels. The simplistically designed box is easy to use and has a good seal, keeping the box tightly closed. It is shipped as an upgraded version with an improved fan.

Eryone M1, M2 – Dryer Box Snail

Price: $38-59
Product links:
Amazon | AliExpress | Official Website

Eryone M1 has a slim, snail-like design that has surprisingly many functions. It combines drying with the help of desiccant dehumidifiers and a heating option.

It was delivered in a box slightly bigger than a 1kg filament spool. It is designed to hold the standard 750g-1000g spools, but when I tested a smaller spool, it also worked. The smooth metal base surface and relatively light weight of the spool allowed it to roll in the box.

It took us about one day to decrease humidity from 46% to 24%. We had to switch the heating function back on several times because it stays on for four hours. The Bowden extruder-setup 3D printer, like Neptune 3, worked well.

Filament dryers with such a compact design could be the best solution for those with a limited budget and space.

DIY Solutions and Innovations

Even though many 3D printing-related brands launched filament drying products, many DIY solutions and tutorials are available online. These may look less appealing, but they are sometimes as effective as the commercial versions. Also, cost-wise, these are much cheaper to build, and volume-wise, they are more productive.

– IKEA Storage Box. Following one of the first results in a Google search, we found a video on how to turn an IKEA storage box into an effective dry box. Generally, many storage boxes and food containers that can be turned into dry boxes can be found online.

– High-Temperature and Annealing. High-temperature filament dryers enable the maintenance of advanced engineering-grade materials like PA-Nylon, PC-ABS, ASA, and CF-Carbon Fiber blends. The annealing post-processing feature allowing users to experiment and post-process filaments and prints in a controlled environment.

No more invading the kitchen! Using the FilaDryer E2, for example, it is possible to dry loose desiccant and sachets in approximately 30 minutes on full power. While this can be done faster in a regular microwave on defrost mode, having the option to do it in the workshop is highly convenient.

– RepBox System. This system was initially designed to protect multiple filament spools, such as dust, from the environment. It also helps arrange multiple spools for multi-material 3D printing. Another great benefit of this product is that it can be installed on the wall and, therefore, saves space on the table. According to the manufacturer, it does provide some protection from moisture if desiccant dehumidifier packets are added. Check RepBox products at Repkord.

Filament Storage Bags with Electric Pumps
Storage bags are a popular method for keeping filament dry, and even simple food bags with a few desiccants can work in the short term. But over time, mishandling, weak seals, or unnoticed desiccant failure can compromise spool quality.

Conclusion

Filament dryers can help both casual and professional 3D printer users, especially in situations with high air humidity. I would keep one of these machines handy to maintain and keep filaments in the best shape. I also added a filament dryer as an optional tool for FDM 3D printers to the ever-expanding list.
