Rapid Prototyping and Manufacturing of Refractory Metal Parts Based on SLS Technique

摘要：

A novel preparation of polymer-coated Mo powder and its selective laser sintering rapid prototyping technique are introduced in this text, which can be used to manufacturing refractory metal parts. The laser sintering experiments of polymer-coated Mo powder was conducted in the self-developed laser sintering machine, and optimized parameters have been acquired. At last, the post treatment process of laser sintered parts has been developed and refractory metal parts of Mo/Cu composites are gained. The post treatment process includes debinding, high temperature sintering and melting infiltration, which is sintering framework-Mo by high temperature combining with Cu impregnation method. It is found that the mechanical properties of parts have been greatly improved after the post treatment process.
