使用阿基米德排水法,测试样品的密度,分别测试激光功率(160-240W),扫描速度(300-700mm/s),扫描间距(0.04-0.08mm)和粉层厚度(0.03mm)下的密度,其中最佳的工艺参数为200W,500mm/s,0.05mm和0.03mm下LPBF样品的密度最高,达到7.292g/cm3
The Archimedes method was used to test the density of the sample, and the laser power (160-240W), the scanning speed (300-700mm/s), the hatching spacing (0.04-0.08mm) and the layer thickness (0.03mm) were tested respectively. The optimum process parameters were 200W, 500mm/s, 0.05mm and 0.03mm, and the highest density of LPBF sample was 7.292g/cm3
