INFLUENCE OF BASIC PROCESS PARAMETERS ON MECHANICAL AND INTERNAL PROPERTIES OF 316L STEEL IN SLM PROCESS FOR RENISHAW AM400

Abstract

The paper deals with the study and experimental evaluation of the influence of process parameters determining the resulting mechanical properties of the components after additive production using the 1.4404 (316L) stainless steel SLM method. The determining process parameters that have been investigated are laser power, scanning speed and layer creation strategy. These parameters fundamentally affect the microstructure and macrostructure of components created by the SLM method, therefore, they have been subjected to closer examination. The results then determined the ideal set of parameters according to the assessment criteria - tensile test, porosity and roughness of the surface. Experiments were performed on the Renishaw AM400 and therefore the results and recommendations are directly related to this particular machine.
