No More Wet Filament! Top Filament Dryers from Sunlu, Creality, Bambu Lab & More

The Sunlu FilaDryer E2 is a pioneering dryer designed for engineering-grade materials, reaching temperatures up to 110°C, which is the highest in the desktop class. This makes it ideal for demanding filaments like PA-CF, PA-GF, and PC. The 500W PTC heating system reaches 70°C in 30 minutes and features 360° hot air circulation for even drying.

In addition to high-heat, what makes the E2 unique is its annealing capability, enabling you to heat-treat finished prints to improve their mechanical strength. The dual-chamber insulation keeps the exterior cool (below 60°C) even at maximum temperature. It holds two 1kg spools or one 3kg spool (up to Ø250mm×153mm) and includes built-in preset settings for common materials. The sealed design with silicone gaskets and magnetic closures prevents moisture reabsorption. Compatible with 1.75mm and 2.85mm filaments, the E2 includes intelligent protection with automatic shutdown if overheating occurs.

Sunlu also offers the FilaDryer S2, a more affordable option also with 360° heating, temperatures from 35-70°C, and a large touchscreen with preset drying parameters for common materials. It accommodates spools up to 210 x 85 mm.

Many hobbyists will be perfectly happy with the S2, while the E2 is better suited to users who already experiment with engineering‑grade plastics.

Creality’s Space Pi X4 is a four‑spool “command center” for filament, with two independent heated chambers that can dry and feed up to four spools at once. Each chamber has its own 200W PTC heater (400W total), reaching temperatures up to 85°C, so hot enough for engineering filaments like PA-CF and PAHT, the company says. The dryer reaches 50°C in about 7 minutes. It is aimed at multi‑printer or multi‑material setups rather than a single desktop machine.

The SpacePi X4 isn’t listed down below with the material stations from Bambu Lab and other because it isn’t tied to a specific printer brand and has controls right on the unit. In other words, you can use it as a stand-alone dryer, but when it comes to the filament feeding system via PTFE tube, it may require that your printer supports a standard filament feed path, which some non-Creality printers do.

The Creality also offers a single-spool ($60) and double-spool ($80) version of the Space Pi dryer that also get up to a toasty 70 ºC.

Polymaker’s PolyDryer pairs a heated base (“dock”) with a sealed storage box that can be stacked or used as a passive container. The idea is to dry filament on the dock, then leave it in the same box for low‑humidity storage and direct feeding to the printer.

It targets the mainstream range (PLA, PETG, ABS, ASA, PA, TPU, PC) according to PolyMaker, rather than extreme‑temperature filaments, and is especially attractive for users already invested in Polymaker materials who like the idea of matched profiles and always‑ready spools.

Rather than setting a specific temperature, the 360° airflow system has three power levels. What sets it apart is exceptional sealing, Polymaker’s tests show less than 5% humidity change over 30 days, and claims to be 1.5 times better than DIY solutions. Each box comes with moisture-absorbing desiccant. When you notice the most of desiccant has changed color from orange to dark green, then the desiccant has absorbed enough moisture and must be dried in a oven or microwave.

The new eSun eBox Pro features 360° surround heating using a “PI heating film”, turbo fan, and metal heat conduction plates for uniform drying. It reaches a maximum of 70°C with drying times up to 99 hours, suitable for engineering materials like PA, PC, and TPU. The large color LCD touchscreen displays real-time temperature, humidity, and remaining time, with intelligent recommendations for different materials.

The unit accommodates 0.5kg to 1kg spools and works with 1.75 mm, 2.85 mm, and 3.0mm filaments. You can print directly from the dryer through silicone-plugged output holes. The curved heating plate ensures even heat distribution, while insulation and flame-retardant materials provide safety. The turbo fan operates quietly while maintaining efficient drying.

Although the eBox Pro was launched in June, it is not yet widely available with some store saying it should be in stock by April 2026.

eSun’s eBox Pro is a new upgrade to the actually available eBox Lite, a more economical version ( that removes the weighing function while keeping essential drying capabilities. It features a maximum temperature of 50 ºC, only bottom heating, and fewer features, but comes at a lower price ($40) for budget-conscious users.

The Chitu Systems FilaPartner E1 is a modular, dual-chamber filament dryer and storage system that can dry up to four filament spools at once. Each chamber features independent temperature control (adjustable up to ~70 °C) and built-in airflow, which ensures rapid and even moisture removal so filaments remain dry and print-ready, the company says.

The E1 automatically monitors humidity and can be set to “auto-dry” mode, which triggers drying when humidity rises above a threshold and stops once optimal dryness is reached, helping prevent moisture-related print defects like bubbling, stringing, and weak layer adhesion. Because each chamber is removable and stackable, the system is flexible enough to handle multiple filament types or feed multiple printers — all while preserving spool quality and reducing waste over time.

You can print directly from the E1 storage boxes depending on your printer type.

Announced in July, the E1, unfortunately, is still listed by Chitu at for “pre-order”.

Sovol offers three dryers at various prices. The SH01 is the budget entry, holding two 1kg spools with temperatures of 40-50°C. It has a 2-inch LCD screen, silicone gaskets for sealing, and four outlet holes for flexible filament routing. Simple and affordable, but limited to basic materials.

The SH02 is the performance model with 150W PTC heating reaching 50°C in 7 minutes and 70°C in 25 minutes. Temperature range of 40-70°C handles materials like ABS, TPU, PETG, PA, and PC. The 3.9-inch touchscreen has one-key presets for nine filament types. Triple sealing rings provide better moisture protection than the SH01, and safety features include PTC overheat protection (cuts off at 130°C) and fan monitoring. Holds two 1kg spools.

The SH04 takes a different approach: maximum simplicity with capacity for four spools. With 690W power from dual heating bars, it reaches 50°C in 13 minutes—58% faster than the SH01. The one-knob control is simple: set drying time (up to 120 minutes) or turn to “Stay On” for continuous operation. Temperature is fixed at 50°C (maintained between 45-55°C), which works for most common materials including PLA, PETG, ABS, and TPU. Great for multi-color printing or running multiple printers.

The PrintDry PRO 3 uses closed-loop temperature control with six preset levels: 35°C, 45°C, 55°C, 65°C, 75°C, and 85°C. The built-in timer runs up to 48 hours with auto shut-off. Air circulation moves heat throughout the double-wall insulated chamber. The base model holds two spools up to 200 mm diameter.

What makes the PRO 3 stand out is expandability. The optional Large Spool Kit handles spools up to 5kg and 300mm (12″) diameter. The Additional Chamber Kit expands capacity to four total spools. This stackable, modular design lets you customize based on your needs. You can print directly from the dryer while maintaining optimal conditions. At 245W power consumption, it’s suitable for everything from PLA to engineering materials like Nylon and PC. It’s ETL certified for North America and CE/TUV certified for Europe.

The Eibos Tetras is a specialized upgrade for Bambu Lab AMS 1 systems (not compatible with AMS 2), transforming them into active drying systems. Currently on pre-order, it ships starting in 2026 if you were to order now. Each of the four independent chambers has its own control screen with temperatures from 20-65°C, drying times from 30 minutes to 24 hours, and three power levels.

External air circulation forces dry air into each sealed chamber while evacuating moisture. Two-stage drying first removes moisture aggressively, then applies gentle heat to maintain consistent feeding. After drying, it automatically switches to Smart Storage Mode, monitoring humidity and restarting if moisture rises above your set threshold. Installation takes 10-20 minutes—just replace the AMS top cover (4 screws) and install new foot pads. No firmware modifications needed; it runs on its own power and control system.

Eibos also makes the Polyphemus, a dual-spool dryer with unique 360° automatic rotation driven by a motor. With 130W power and temperatures from 30-70°C, it holds two 1kg spools or one larger spool (expandable to Ø250×170mm). The rotation ensures only 1°C temperature difference across the spool versus 36°C for static heating. It has eight filament outlet holes for flexible routing and built-in parameters for nine materials plus three custom slots.

The company’s most economical solution is the single-spool Easydry that gets up to 65 ºC with hot air circulation heating.

If you own a Bambu Lab 3D printer, the company debuted it’s first filament dryer this year, as an upgrade to its multi-material handling system, the AMS. Bambu Lab’s AMS 2 Prois a multi-filament system that combines airtight spool storage with active drying to keep filament in optimal condition. Unfortunately, you can’t print using the AMS while the dryer is running.

AMS 2 Pro uses active air venting and controlled heat up to about 65 °C to remove moisture from up to four spools at once, helping prevent moisture-related printing issues like poor extrusion or nozzle clogs.

The system also regularly rotates spools during drying for more even dehumidification and monitors internal temperature and humidity to support reliable moisture control. Its drying functions are integrated with sealed storage and RFID tracking, making it a convenient solution for maintaining filament readiness and consistent print quality if you have a Bambu Lab 3D printer.

Unlike the Creality multi-spool dryer, the Bambu Lab AMS Pro and HT do have their own controls on the unit and can only be controlled through (and when hooked up to) a Bambu Lab 3D printer. This unit is compatible with the H2 Series and X1, P1, and A1 series with and upgrade kit.

Bambu Lab notes that the AMS 2 Pro doesn’t get hot enough to full dry certain materials, like ABS, ASA, PA, PC, PP and carbon-fiber filled materials. For those, the company recently launched a high-temperature (HT) unit called the Bambu Lab AMS HT ($139), which has all the drying features of he AMS 2 Pro but is a single-spool dryer that can get up to 85 ºC. The HT is also only controlable via Bambu Lab printer software and does not support printing while drying.

Anycubic ACE Pro is a multi-filament hub designed for multi-color and multi-material printing that also actively dries filament to keep it ready for use. On its official product page, Anycubic highlights that the ACE Pro “dries while it prints in multi-color” — meaning filament undergoes active drying even during a print job.

Inside the ACE Pro there’s a dual PTC heating system (supported by airflow) which warms the filament chamber to up to ≈ 55 °C, helping remove absorbed moisture and prevent moisture-related print issues like poor extrusion or nozzle clogs.

Like the Bambu Lab, the Anycubic ACE Pro is not a stand-alone unit, it is controlled by the Kobra 3.

The Qidi Box is a multi-filament management system that doubles as an active filament dryer. It maintains a sealed internal chamber and heaters that raise the temperature to as much as 65 °C, continuously drying spools — even while printing — so hygroscopic and moisture-sensitive filaments stay ready for quality extrusion. The system monitors temperature and humidity in real time, rotates the spools periodically to ensure uniform drying, and offers sealed storage to prevent re-absorption of moisture.

Qidi Box is compatible with the Qidi Plus4 and only controllable via the Qidi software suite.
