Abstract
An additive manufacturing device includes at least one liquefier assembly that receives filament material from at least one feedstock and extrudes the material in a flowable form. A thermal drying system removes water vapor and heats compressed air to a preselected temperature set point to form conditioned air. At least one enclosed filament path houses and guides the filament material from a supply to the at least one liquefier assembly. The enclosed filament path is exposed to the conditioned air from the thermal drying system so as to keep the filament material dry as it is fed to the at least one liquefier assembly.
