Warping Distortion Defect of Selective Laser Sintering Rapid Prototyping Work Pieces

Qin Lanyun

Abstract

The warping distortion defect of work pieces formed by selective laser sintering process has a great influence on forming accuracy.Experiments on HRPS-ⅢA form machine on rapid prototyping were conducted to find out the root reasons of warping distortion.The influence of technological parameters of the laser scanning rate、laser power and the powder preheated temperature on the rule of warping distortion were obtained and effective measures of reducing warping distortion were proposed.
