In this work, a biocompatible powder, 316L stainless steel, is characterized to understand the particle size, distribution, shape and flowability. Examination revealed that the 316L particles are smooth, nearly spherical, their mean diameter is 39.09 μm and just 10\% of them hold a diameter less than 21.18 μm. SLM parameters under consideration include laser power up to 200 W, 250-1500 mm/s scanning speed, 80 μm hatch spacing, 35 μm layer thickness and a preheated platform. The effect of these on processability is evaluated. More than 100 samples are SLM-manufactured with different process parameters. The tensile results show that is possible to raise the ultimate tensile strength up to 840 MPa, adapting the SLM parameters for a stable processability, avoiding the technological defects caused by residual stress. Correlating with other recent studies on SLM technology, the tensile strength is 20\% improved. To validate the SLM parameters and conditions established, complex bioengineering applications such as dental bridges and macro-porous grafts are SLM-processed, demonstrating the potential to manufacture medical products with increased mechanical resistance made of 316L.}, language = {en} } @article{GebhardtHoetterZiebura2014, author = {Gebhardt, Andreas and H{\"o}tter, Jan-Steffen and Ziebura, Dawid}, title = {Impact of SLM build parameters on the surface quality}, series = {RTejournal - Forum f{\"u}r Rapid Technologien}, volume = {11 (2014)}, journal = {RTejournal - Forum f{\"u}r Rapid Technologien}, number = {1}, issn = {1614-0923}, pages = {1 -- 14}, year = {2014}, language = {de} } @article{Gebhardt1989, author = {Gebhardt, Andreas}, title = {H{\"a}rten von Kurbelwellen}, pages = {1 -- 14}, year = {1989}, language = {de} } @article{Gebhardt2008, author = {Gebhardt, Andreas}, title = {Hype um Generative Verfahren.
