Mechanical behavior of steel scaffolds made by selective laser melting
Résumé
A mechanical analysis of different architectures of scaffolds processed by selective laser melting (SLM) of 316L stainless steel powder is proposed. Experimental compression tests of scaffolds obtained with different SLM parameters are compared with FEM computations. Identification of the mechanical behavior law parameters of the constitutive material of the scaffolds is made. It is shown that for non post heat treated scaffolds, the identified parameters on a specific architecture are not transferable to predict the compression behavior of an other architecture.
