Design and mechanical failure analysis of Ti6Al4V alloy thin-walled parts by selective laser melting(SLM) manufacture

Abstract

Abstract There is a growing interest in using additive manufacturing to produce smart structures, which have the capability to respond to thermal and mechanical stimulation. In this report, Selective Laser Melting (SLM) is used to build a thin-walled titanium alloy structure. The part creating a ultra lightweight is 2.15g, while its strenght achieve at 132.4MPa. The stages of compression process was analyzed in detail, meanwhile the deformation and failure mechanism of the thin-walled part was described.
