Selective laser sintering (hereinafter referred to as SLS) technology was first introduced by United States Carl ckard of the University of Texas at Austin in 1989, put forward in his master's thesis. Hou United States DTM in 1992, the company introduced the technology commercialization of Sinter Sation of production equipment. For decades, Austin and DTM companies do a lot of research work in the areas of SLS, in equipment and technology, materials development, and achieved fruitful results. Germany's EOS company also did a lot of research in this area, and a corresponding series of molding equipment.
Home also has a number of units SLS-related research, such as XI ' an Jiaotong University School of mechanical, National Engineering Research Center for rapid prototyping, rapid prototyping Engineering Research Center of the Ministry of education, North, Northwestern Polytechnical University, Huazhong University of science, Nanjing Aeronautics and Astronautics University University and Beijing long Yuan automated fabrication company, has also made a number of significant results, such as Nanjing Aeronautics and Astronautics University development RAP-I of laser sintering rapid prototyping system, Beijing long Yuan automated fabrication of limited development commercialization of AFS 1300 laser rapid prototyping equipment.
