[SUNLU FilaDryer E2] The latest 2025 release, designed for engineering materials, assists in seamless creation, drying, and annealing all in one.
[Superior and Efficient Annealing] With a temperature of up to 110 °C, 99.99% of engineering materials on the market can be annealed, allowing materials to reach their full potential and giving your model excellent properties such as exceptional impact resistance and toughness. Suitable for ABS, ABS-CF, ASA, PC, flame-retardant PC, PC-ABS, PC-PBT, CoPA, PA6-GF, PA6-CF, PA12-CF, PA612-CF, PA12, etc...
[Fast and Efficient Drying] 500W PTC ultra-high heating power makes your creation a step faster. It takes only 20 minutes to heat up to 50℃ at room temperature and 30 minutes to heat up to 70℃! The temperature can reach up to 110℃ (when drying at high temperatures, the heat resistance of the filament spool must be considered)
[Excellent Airtightness, Super Insulation Effect] One-piece silicone plug over the wire hole; the cover plate is equipped with sealing silicone strips and a magnetic suction block to isolate water vapor from entering the chamber from the outside. The surrounding dual-chamber design at the top, middle, and bottom allows for a heating temperature of over 100°C. Combined with the innovative locking system, the annealing process is perfected, and the dual requirements of annealing and drying are solved in one machine.
[Extra Large Interior, Super Adaptability]
The maximum compatible spool size is Φ250mm*153mm, which is suitable for most standard spools on the market. Tested, it can hold 2 rolls of regular 1KG spools, 2 rolls of regular 2KG spools, or 1 roll of a regular 3KG spool. (Note that the test spools are SUNLU spools; other brands of spools will have slight differences but are basically compatible; pay attention to the size of the spool when using).
[Strong Compatibility, Adapts to 99% of Application Scenarios]
Can be used for both engineering materials and conventional materials. Built-in preset filament settings, apply the preset with one click. The filament diameter is compatible with most materials on the market (Φ1.75mm, Φ2.85mm), and the included Teflon tube is Φ4*Φ3mm and comes in lengths of 8cm*2 and 1m*2.
[Strong Safety, No More Worries] Intelligent protection system, two-stage temperature control switch, disconnects connection in case of over-temperature, cooling is restored. Double-layer thermal insulation: when the internal temperature is >100℃, the external touch temperature is only <60℃. Fireproof material grade.
[Inspire Engineering Material Potential]
Annealing significantly improves the impact resistance and durability of engineering materials, allowing you to unlock engineering performance in every creation, such as drone accessories, helmets, screws and nuts, blower tubes, etc. Models that must withstand high-intensity impacts and have a long service life.

What is annealing and why is it necessary?
Plastic products are placed in a heated liquid medium or a constant-temperature hot air oven for a certain period and then slowly cooled to room temperature, with the heat accelerating the relaxation of the macromolecules in the plastic, thereby eliminating or reducing the residual stresses in the products after molding.
Elimination of the phenomenon of local stress concentration caused by different cooling rates during the cooling and curing process of plastic products.
This is what the SUNLU FilaDryer E2 offers
- a professional 2-in-1 annealing and drying solution specifically developed for engineering materials.
How is annealing performed?
1. Select the temperature: Determine the correct temperature based on the material.
2. Control heating rate: Ensure that the part is heated evenly.
3. Maintain constant temperature: Adjust the duration according to size and material.
4. Control cooling: Allow for gradual cooling or use controlled cooling to achieve the best results.
Tips for successful annealing!
Test with small models first to reduce trial-and-error costs. Consider shrinkage and adjust your design accordingly.

FAQs
The most important information about the FilaDryer E2 >
The most important information about the FilaDryer E2 >
1. The maximum heating temperature of the SUNLU FilaDryer E2 is up to 110°C. Please carefully ensure that the currently set parameters (such as filament type, heating temperature) are consistent with the actual need to dry the filament, in order to avoid excessively high temperatures that lead to filament deformation (for filament drying temperatures, refer to product manuals or the filament spool data on this product page).
For example, if the device is set to an operating temperature of ≥70°C, the temperature resistance of the spool of the filament you are using should be ≥70°C to avoid deformation of the spool.
2. If the product's set operating temperature is ≥ 80°C, the humidity detection module will be in a protective state (displaying humidity <10%), which is a normal phenomenon. When the drying box temperature is reduced to 70°C for approximately 20 hours, the humidity detection module will automatically restore its original precision.

What do we need to know about how the glow function works?
What do we need to know about how the glow function works?
When using the annealing function (MO2 mode), although some filament annealing temperatures and times are provided in the product manual for reference, it is recommended to use the filament manufacturer's recommended temperatures and times for annealing due to the different characteristics of different manufacturers' filaments.
Can I touch the product while it is operating?
Can I touch the product while it is operating?
Even though the device is protected in many areas, the temperature of the device's outer surface is ≥55℃ when the set operating temperature is ≥80℃. To avoid burns, do not touch the housing or handle the oven while it is in operation (or take appropriate heat protection measures, e.g., wear insulated gloves).
Is there anything else I can do to make the drying process more effective?
Is there anything else I can do to make the drying process more effective?
To ensure the drying effect, please do not open the top cover of the drying box during operation. During the drying process, it is recommended to open the silicone plug of the filament outlet (to allow the internal moisture to escape completely); after the drying process, it is recommended to seal the silicone plug tightly again (to prevent moisture from entering from the outside).

Safety precautions you must observe >
1. Keep this product out of the reach of children. Pay attention to electrical safety during operation. Do not use this product near water, such as in bathrooms, bathtubs, sinks, and other places where water is easily accessible.
2. Please use the original power cord or a power cord that meets safety certification requirements.
3. When the device is not in use, please turn it off to prevent a potential fire.
4. Please do not place the device on temperature-sensitive objects during operation.
5. Do not touch the heater or the fan inside the box while this product is in operation to avoid burns. When drying filaments, the top cover of the drying box should be closed to prevent heat loss.
6. Please do not block the internal air inlets and outlets to avoid abnormal heat buildup.
7. If the device is not working, please turn it off and unplug the power cord from the outlet. Then, contact the customer service team (support@sunlu.com).
