多材料面曝光增材制造方法与加工工艺研究

摘要

零件的多材料组成可改变其机械性能,并增加其他附属功能.通过搭建一种分区旋转槽多材料面曝光增材制造系统,验证了多材料光固化成形工艺,完成了含有两种树脂材料的复杂结构零件的加工.分析了零件的加工质量和加工精度,并进行了多材料界面结合的抗拉和抗剪性能测试.结果表明:所加工的多材料界面在拉应力和剪应力的作用下结合良好.%The multi-material composition of the parts can change its mechanical properties and add other subsidiary functions. The hardware and software designs of the customized multi-material stereolithography (MMSL) were introduced,and the processing of MMSL was verified. Two resins were employed to test the fabrication ability of the system. The quality and accuracy of the parts were analyzed,and the tensile and shear tests of the multi-material interfaces were carried out. The results showed that the multi-material interface were well bonded.
