| 摘 要： | 本文分析变长线扫描选择性激光烧结快速成型工艺对点扫描工艺的质量和效率优势.对二者光学系统结构作分析对比,对焦斑和线束上的功率密度作计算对比.变长线扫描系统采用的扫描方式和聚焦元件使线束宽度小且恒定,线束功率密度与点扫描焦斑的相当.变长线扫描选择性激光烧结快速成型工艺的质量优势是明显的,效率比点扫描工艺提高一倍左右.

| Abstract: | This paper analysed the quality and efficiency of alterable laser thread length scanning in SLS RP processing as compared with the spot scanning processing. Analyses and compares the two constructions of their optical systems and the power densities of two focussing beams. Quality advantage of the alterable thread length scanning system is evident. Its efficiency is about two times higher than the spot scanning processing. |
