Abstract

<p>In this paper, the deformation prediction caused by condition change with Finite Element Analysis is performed for SLM (Selective Laser Melting) modeling. Various methods for predicting thermal strain have been proposed. In this study, finite element analysis is applied to SLM for the purpose of investigating the features and advantages of full thermal analysis and inherent strain method respectively. We verified the modeling method in each method with a very small laminated thickness of several tens of micrometers.</p>
