With drying and annealing functions, the Sunlu E2 filament dryer prepares filaments for 3D printing and can improve the mechanical properties of printed models. Annealing reduces internal stresses created during printing, and the maximum operating temperature reaches 110 °C. The 500 W PTC heater reaches 50 °C in approximately 20 minutes and 70 °C in approximately 30 minutes.

The sealed chamber with silicone gaskets and magnetic closure, together with double insulation, helps maintain a stable temperature. It supports 1.75 mm and 2.85 mm diameter filaments, including PLA, PETG, TPU, ABS, ASA, PC, and PA. Safety features include temperature control, automatic shutdown in case of overheating, and warning alarms.
