Direct Metal Laser Sintering Some improvements of the materials and process

摘要

For a comprehensive understanding of the direct metal laser sintering (DMLS) process and for the successful introduction of this technology, some investigations related to the characteristics of the powders and the individual sintered layers were therefore performed. Also possibilities of hard coatings deposition for further improvements the wear and temperature resistance of tool inserts, and investigations particularly focused into the industrial applications of DMLS tooling inserts are presented.
