摘要

从理论和试验两个方面对选择性激光烧结件精度的影响因素进行了研究

验证了激光烧结参数、烧结温度等对制件精度的影响。针对影响烧结金属粉末尺寸精度的工艺参数

以316不锈钢粉末为试验材料

以制件尺寸为测量指标

优化了一组烧结参数:激光功率为83W、扫描速度为16mm/s、烧结间距为0.165mm、单层厚度为0.1mm

精度可达到±0.05mm

用此工艺参数成功地烧制出了金属原型件。

Abstract

Factors influencing precision of selected laser sintered parts were analyzed based on theory and experiment

especially laser sintering parameters and sintering temperature. A set of processing parameters influencing size precision of metal powder were optimized through setting parts size as optimized target using 316 stainless steel as follows: laser power of 83W

scanning velocity of 16 mm/s

scanning spacing of 1/6 mm

thickness of sintering layer of 0.1 mm. Using these optimized sintering parameters

the precision of the part can reach ±0.05 mm

and metal prototype parts were fabricated successfully.
