摘要

激光增材制造技术主要包括粉末床熔融(PBF)和定向能量沉积(DED),粉末床熔融指的是激光选区熔化(SLM),定向能量沉积指的是激光近净成形(LENS)。伴随着这些技术"诞生"了相应的激光增材制造设备。以华南理工大学相应设备研发为例,介绍了相关技术设备现状,并展望了激光增材制造设备未来的发展。

Abstract

Laser additive manufacturing technology mainly includes powder bed melting（PBF） and directed energy deposition（DED）. In this paper,powder bed melting refers to laser selective melting（SLM）,and directed energy deposition refers to laser near-net shaping（LENS）. Along with these technologies came the corresponding laser additive manufacturing equipment.Taking the research and development of corresponding equip-ment in South China University of Technology as an example,this paper introduces the present situation of relevant technical equipment,and looks forward to the future development of laser additive manufacturing equipment.
