Recent research work has been focused on direct laser sintering of metal or ceramic materials for functional parts, as well as tooling. In this paper, a process for direct laser sintering of a copper-based alloy is presented. The sintering process was conducted on a specially developed high temperature laser manufacturing system (HTLMS). The effect of the process parameters on the properties of the laser-sintered parts was studied. The mechanism of the direct laser sintering of the copper-based alloy was investigated. The density, surface roughness and mechanical properties of laser-sintered parts were measured and analysed. The optimised process parameter setting achieved from the experimental study has been successfully applied to build a pair of copper-based injection mold inserts.||Source Title:||Materials Science Forum||URI:||http://scholarbank.nus.edu.sg/handle/10635/73481||ISSN:||02555476|
