摘　　要：为避免传统雕刻式金属浮雕加工过程中的材料浪费,实现金属浮雕的快速制造,提出了一种基于选区激光熔化(SLM)的从图像直接制造金属浮雕的方法.针对现有浮雕设计软件对SLM支持不足的缺点,利用可视化工具包(VTK)和扫描路径生成库(SPGL)开发了用于SLM的浮雕设计制造软件.该软件具有3D浮雕建模、浮雕模型切片、扫描路径生成和加工代码生成等主要功能,能够将图像直接转化成用于SLM设备的加工代码.为利用SLM分层制造的优点,减少材料消耗,文中还探讨了空心浮雕的直接制造过程.最后用316L不锈钢粉在SLM设备上进行了金属浮雕的加工实验.结果表明,文中方法是可行的.In order to avoid the waste of materials in the traditional manufacturing of metal bas-reliefs via carving and to implement rapid manufacturing,a method of directly manufacturing metal bas-reliefs from images is proposed based on the selective laser melting（SLM）.As the current bas-relief design software is insufficient for SLM,software is programmed by using the Visualization Toolkit（VTK） and the Scanning Path Generation Library（SPGL）,which has such main functions as 3D bas-relief modeling,bas-relief model slicing,scanning path generating and processing code generating,and can generate the processing codes of a SLM device from images directly.More-over,a direct manufacturing process of hollow bas-relief is investigated to reduce the material consumption and take advantage of the layered manufacturing of SLM.Experimental results on a SLM device using 316L stainless steel powder show that the proposed method is feasible.
