Residual stress in selective laser sintering and selective laser melting

Abstract

This paper presents an investigation into residual stresses in- Selective Laser Sintering and Selective Laser Melting. First, the origin of these stresses is explored, and a simple theoretical model is presented to predict the residual stress distribution. Nest, an experimental model is developed, which can be used to actual residual stresses. remaining in the ports produced. A set of test samples is then tested to investigate the influence of the parameters on the residual stresses being developed- At the last some methods to refuce the residual stress are presented .status: publishe
