Nowadays, Industrial competition power is depended on that rapidly produce the customized products. Therefor, it is necessary to reduce period of product development. Thus, concurrent engineering that work many process at a time was appeared and Rapid prototyping was appeared, it is method that rapidly produce the prototype. If the graphic model was made by CAD, the prototype can be made in short term. That provide what the part was directly tested by the worker. It provide a worker with believable data. We study on the influence of surface roughness on injection interval and part angle at FDM.
FDM에서 곡면부의 접선기울기가 제품의 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 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
