翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Selective laser sintering ： ウィキペディア英語版 Selective laser sintering Selective Laser Sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power source to sinter powdered material (typically metal), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure. It is similar to direct metal laser sintering (DMLS); the two are instantiations of the same concept but differ in technical details. Selective laser melting (SLM) uses a comparable concept, but in SLM the material is fully melted rather than sintered,〔(【引用サイトリンク】url=https://thre3d.com/how-it-works/powder-bed-fusion/selective-laser-sintering-sls )〕 allowing different properties (crystal structure, porosity, and so on). SLS (as well as the other mentioned AM techniques) is a relatively new technology that so far has mainly been used for rapid prototyping and for low-volume production of component parts. Production roles are expanding as the commercialization of AM technology improves. ==History== Selective laser sintering (SLS) was developed and patented by Dr. Carl Deckard and academic adviser, Dr. Joe Beaman at the University of Texas at Austin in the mid-1980s, under sponsorship of DARPA.〔Deckard, C., "Method and apparatus for producing parts by selective sintering", , filed October 17, 1986, published September 5, 1989.〕 Deckard and Beaman were involved in the resulting start up company DTM, established to design and build the SLS machines. In 2001, 3D Systems the biggest competitor of DTM and SLS technology acquired DTM.〔Lou, Alex and Grosvenor, Carol "(Selective Laser Sintering, Birth of an Industry )", ''The University of Texas'', December 07, 2012. Retrieved on March 22, 2013.〕 The most recent patent regarding Deckard's SLS technology was issued 28 January 1997 and expired 28 Jan 2014.〔(US5597589 )〕 A similar process was patented without being commercialized by R. F. Housholder in 1979.〔Housholder, R., "Molding Process", , filed December 3, 1979, published January 27, 1981.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Selective laser sintering」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
