The materials expert Sunlu presents the new FilaDryer E2 filament dryer. This advanced version has been specifically developed for technically savvy users who want to optimize their print results through precise filament drying and additionally experiment with heat treatments (annealing).
The device is securely packaged and comes with a clear scope of delivery. In addition to the FilaDryer E2, it includes a power cord, four PTFE tubes, a heat-resistant tray for heat treatment, and a manual.
Equipped with a powerful 500-watt heating element, the device heats up quickly: it reaches a temperature of 50 °C within 20 minutes, and 70 °C after 30 minutes – perfect for users who want to start printing quickly. Sealing the housing with silicone strips and a magnetic closure system reliably prevents the escape of heat and moisture.
The spacious interior offers room for large filament spools. Up to two 1 or 2 kg spools or one single 3 kg spool can be processed. The dryer is compatible with spool dimensions of up to 250 mm in diameter and 153 mm in width – ideal for versatile applications.
Operating the FilaDryer E2 is particularly user-friendly thanks to pre-set filament profiles for materials such as PLA, PETG, and Nylon. The optimal drying parameters are set with just one click. For specific requirements, the touchscreen controller offers additional adjustment options, allowing the device to be flexibly tailored to individual needs.
SUNLU places great importance on safety: an intelligent protection function automatically interrupts operation in case of over-temperature and resumes it automatically after cooling down. Double insulation ensures that the exterior temperature remains safely below 60 °C, even with an internal heat of 100 °C. Thus, the FilaDryer E2 ensures not only precise drying results but also a high level of safety in daily use.
Heat treatment / Annealing
With a maximum operating temperature of 110 °C, the FilaDryer E2 is suitable not only for filament drying but also for the heat treatment (annealing) of already printed parts. Targeted annealing can significantly improve material properties, leading to increased impact resistance and load-bearing capacity of the models. This function is ideal for high-performance components such as drone parts, helmets, or screws.
The high operating temperature allows for the processing of materials such as ABS, ASA, and PC, as well as glass and carbon fiber reinforced variants like PA6-CF or PA12-CF. As such, the FilaDryer E2 offers a flexible and powerful solution for demanding applications.
