NON-CONTACT TYPE FUSED DEPOSITION MODELING DEVICE AND FDM HEAD UNIT

摘要

Disclosed are a non-contact type fused deposition modeling (FDM) device and a FDM head unit. The FDM head unit comprises: a body unit; a bobbin unit coupled a rotation shaft to the body unit, and rolled with a polymer filament on the outer circumferential surface; a roller unit for transporting the polymer filament in a downward direction, which is rolled in the bobbin unit by rotary motion engaged two wheels with each other; and a heater unit for heating the polymer filament transported by the roller unit in a non-contact way.
