Benchmark Study on Mechanical Properties of Rapid Prototypes
쾌속 조형품의 기계적물성치 비교에 관한 연구
Abstract
In these days, various kinds of rapid prototyping processes are available, such as stereo-lithography apparatus(SLA), fused deposition modeling(FDM), selective laser sintering(SLS), 3 dimensional printing(3DP), and laminated object manufacturing(LOM). For detailed informations about mechanical properties of those parts, benchmark tests are carried out. SLS and EOS part has an advantage in compressive strength, SLA has in hardness, FDM part has in impact strength, and LOM part has an advantage in tensile strength and heat resistance. The change of building direction in layered manufacturing processes of FDM and LOM severely weakens the tensile and impact strength.
