As an inline system, the dryer dries only the part of the filament used for printing during the 3D printing process, not the entire spool. With conventional methods, drying the wet filament can take up to 48 hours and damage the filament spool and/or the filament itself. The filament drying process is pre-calibrated and tailored to each material type, eliminating... the guesswork required when using conventional drying methods.
