FDM에서 곡면부의 접선기울기가 제품의 표면에 미치는 영향

Abstract

Fused deposition modelling(FDM) is a rapid prototyping(RP) process that fabricates part layer by layer by deposition of molten thermoplastic material extruded from a nozzle. RP system has many benefits. One of the benefits would be the ability to experiment with physical objects of any complexity in a relatively short period of time. But it has a problem of surface roughness and geometric accuracy. We study on influence of tangent line angle on surface roughness of curved prototype at fused deposition
