Geometry Processing for SLSIHIP

Abstract

SLSIHIP is a new net shape manufacturing method that combines the strengths of direct selective laser sintering and hot isostatic pressing. Direct selective laser sintering is a rapid manufacturing technique that can produce high density metal parts of complex geornetry with an integral, gas iinpenneable skin. These parts can then be directly post-processed by containerless HIP. Sophisticated processing of the part geometry is required to facilitate the desired results from SLSIHIP. This paper presents geometry processing algorithms being developed for in-situ canning of SLSIHIP components. This research is funded by DARPAIONR contract NO00 14-95-C-0 139 titled "Low Cost Metal Processing Using SLSIHIP".
