The Fila Dryer S1 is designed to help you protect PLA, PETG, TPU, and ABS filaments from moisture, dust, and other environmental factors. By maintaining a constant, optimal temperature inside the box, the Fila Dryer S1 ensures that your filament is kept at a suitable temperature for printing, ensuring that your print results can remain more consistent, especially for larger projects. Additionally, the built-in timer function allows you to preheat the filament so it's ready to go when you are. The box's seal also comes with an opening so the filament can be safely fed out without altering the interior temperature.
