Heat treatment of AM parts produced by various printing technologies
The article describes the results of the heat treatment of additively manufactured (AM) parts made of AISI H13 tool steel. Powder Bed Fusion (PBF), Direct metal Deposition (DED) and Metal Jet Printing (MJP) technologies were used for printing. Due to the different printing technology, the properties and microstructure of the parts also differ, which also affects the choice of heat treatment parameters. The results show a great sensitivity of quenching and tempering temperatures. Also, the differences in the final properties of parts produced by various AM technologies differ, both in terms of properties (hardness, wear resistance) and structure. This can have a significant effect on the performance of the molds and parts produced in this way.
