摘　　要：选择性激光烧结技术是RP&M(Rapid Prototyping&Manufacturing)技术中发展最快和应用最广的技术之一,是一种基于离散—堆积原理的快速成型技术。它选材广泛,操作简单,产品的复杂程度不会对其产生影响,可以直接烧结成件,广泛应用于制造业,选择性激光烧结技术的发展受到越来越广泛的重视。如果突破瓶颈,有望在未来一段时间内得到普及。未来随着SLS技术的快速发展,将会对设备的研发、技术的应用、新工艺和材料的研发产生更为积极的影响,对传统制造业迈向环保、节能、高效发展提供了巨大的推动力。介绍了选择性激光烧结技术的成型原理和特点,概括阐述了SLS技术中应用较多的原材料的研究现状和应用,分析SLS技术产业化存在的问题及可能解决的途径。Selective laser sintering is one of the fastest growing and most widely used technologies in RP & M( Rapid Prototyping & Manufacturing) technology,a rapid prototyping technology based on the discrete-stacking principle. It is widely selected,easy to operate,the complexity of the product will not have an impact on it,which can be directly sintered parts,widely used in manufacturing,and selective laser sintering technology has received more and more attention. It is expected to be popularized in the next period of time if we want to break through the bottleneck. In the future,with the rapid development of SLS technology,it will have a more positive impact on R & D of equipment,application of technology,research and development of new processes and materials,and provide a huge impetus to the traditional manufacturing industry towards environmental protection,energy saving and efficient development force.Introduced the forming principle and characteristics of selective laser sintering technology,summarized the application of SLS technology were introduced and more research situation and application of raw materials,analyzes the problems existing in the industrialization of SLS technology and possible solutions.
