Artifact test design for improving the performance of the SLM process

Abstract

The work contained in this document consists in optimizing and improving the selective laser melting manufacturing process, this technology which, despite having been studied for more than twenty years, remains not completely controlled, because it sometimes happens that the parts obtained contain defects that qualify them as non-compliant or even machine stops in the middle of manufacturing. These problems are usually due to a design that is not adapted to the process. This work seeks to minimize these stops, to do this, test trays have been printed to evaluate the machine’s performance and study the feasibility of the parts produced by selective laser melting.The work contained in this document consists in optimizing and improving the selective laser melting manufacturing process, this technology which, despite having been studied for more than twenty years, remains not completely controlled, because it sometimes happens that the parts obtained contain defects that qualify them as non-compliant or even machine stops in the middle of manufacturing.
