517 The Application of Brazing Process in Selective Laser Sintering Fabricated Part

概要

論文の詳細を見る
Selective Laser Sintering is one of the rapid prototyping technologies in the market. It was attracted much attention and interest since the introduction of metal object fabrication by metal layer sintering. The success of this technology mainly lies on its ability to fabricate complicated shape object in shorter time and cheaper cost. However the complexity of new metal object design has reached to a level that some special shape objects could not be fabricated without post infiltration joining works due to its process limitation. This paper has studied the feasibility of using brazing process in joining the sintered parts fabricated by selective laser sintering method. Suitable brazing metal were chosen by wettability test and the application example of the new model heat exchanger fabrication was discussed in this paper.
