EXPERIMENTAL VERIFICATION OF PROCESS PARAMETERS INFLUENCING THE MECHANICAL PROPERTIES OF M300 IN THE SLM PROCESS

Abstract

The main goal of this paper is to present the results of experimental verification of process parameters affecting mechanical properties of M300 material in the Selective Laser Melting (SLM) process. To obtain the values of mechanical properties, the samples were subjected to tensile testing, where the force, and elongation values were obtained. Therefore, from these values, the values of yield strength, elastic modulus, force and stress at the interface, tensile strength were then derived. It was also possible to construct tensile test F - ∆L: force-elongation diagrams for all specimens, and to construct an R – Ɛ: stress-strain dependency diagram using the calculation of the original area and original length of the specimen. As a result of this work, mechanical property diagram was produced as a function of the process parameters used, showing which parameters most appropriate for the desired properties on the Renishaw AM400 printer.
