中国航天科技集团公司上海航天技术研究院成功研制出我国首台航天多激光金属3D打印机。这台3D打印机形如一个银灰色柜子,柜子左上侧设置了一个小小的玻璃窗,右上侧设置了电脑及键盘,制作人员在电脑上输入需要打印的模型,放入粉末状的打印材料,按下打印键,就可以从玻璃窗里看到,打印材料被一层层地送入打印区域,从底部向上打印,机器不断循环“送粉—铺粉—激光熔化”过程,粉末每铺一层,激光束 China Aerospace Science and Technology Corporation Shanghai Aerospace Technology Research Institute successfully developed China’s first aerospace and multi-laser metal 3D printer. This 3D printer is shaped like a silver-gray cabinet with a small glass window on the upper left side and a computer and keyboard on the upper right side. The production staff input the model to be printed on the computer, put the printed material in powder form, Press the print button, you can see from the glass window, the print material is layer by layer into the print area, print from the bottom up, the machine constantly circulating “powder - dough - laser melting ” process, Shop a layer of laser beam
