详细讨论了表面张力、粘度、颗粒尺寸及其分布和吸收率/反射率等材料特性以及激光参数、铺粉厚度、保护气氛、粉床预热温度和烧结辅助材料等工艺参数对成形质量的影响;

• The material properties such as surface tension, viscosity, particle size and its distribution, and absorbance/ reflectivity together with the processing variables such as laser parameters, layering thickness of powders, atmospheric control, bed pre-heating temperature, and sintering assisted material, which affect sintering and densification of DMLS-processed parts, were discussed.
