Influence of tangent line angle on surface roughness at fused deposition

FDM에서 곡면부의 접선기울기가 쾌속조형물의 표면에 미치는 영향

Fused deposition modelling(FDM) is a rapid prototyping(RP) process that fabricates part layer by layer by deposition of molten thermoplastic 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 study on Influence of tangent line angle on surface roughness at fused deposition
