💡 What is a filament dryer used for in 3D printing workflows?

Filament dryers remove moisture from filaments to improve printing consistency and finish. - moisture removal improves layer adhesion and reduces stringing
- even temperature distribution with 3 circulation fans and 350W heater
- supports multiple filament sizes and materials (1.75, 2.85, 3.00 mm)
- reduces print issues with hygroscopic filaments like Nylon, PETG, ABS, and PLA
