Research of Metallic Part Fabrication by Selective Laser Melting

Article Preview

Abstract:

The primary goal of this research is the fabrication and measure of metal part made by SLM (selective laser melting) system. The SLM system is separated into two sections which are hard system and software system. The hard system is consisted of an Yb-fiber laser, an optical scanner, a powder coating device, a gas purification system and a CNC system; the software system is mainly consisted of CAD model display module, slicing and path layout module and processing control module. A removable partial denture framework was fabricated by this SLM system using stainless steel. A method of metal part precision with complex shape is that using reverse engineering and the average tolerance of metal part fabricated by SLM is ±0.172mm by using this method. The experimental results showed that SLM system developed by us can settle for the need of laser rapid prototyping in metal part fabrication.
