Study of a change of Surface roughness of sphere by adjustment of extrusion at fused deposition

FDM 장치에서 주사량 조정에 대한 구면체의 표면정도 변화에 관한 연구

Fused deposition modelling(FDM) is a rapid prototyping(RP) process that fabricates part layer by layer by deposition of molten thennoplastic material extrude from a nozzle. RP system has many benefit. One of the benefit would be the ability to experiment with physical objects of any complexity in a relatively short period of time. But it has a matter of surface roughness and geometric accuracy. We research into a change of Surface roughness making the sphere by adjustment of extrusion in FDM.
