Abstract

Additive manufacturing refers to the group of new manufacturing methods where parts are built layer by layer starting from a digital file. Using these technologies, it is possible to produce parts with an incomparable design freedom with, potentially, any material. The quality of the built products depend mainly on the machine capabilities, the quality and type of metal powder used, and the choice of process parameters. The paper presents aims to study the origin of defects that appear on the polished surface of the metal additive manufactured parts using selective laser melting of maraging steel grade 300 and how they can be reduced. The main purpose is to understand how these defects can influence the quality of the injection moulded products, when additive manufacturing is used to produce the moulds.
