Study of selective laser melting process for cubic models with various porosities

Additive manufacturing (AM) has the advantages of fabricating complex models for application. In this study, cube structure with various porosity is manufactured by AM of selective laser melting (SLM). CAD software is used to create the micro porosity of sample models from 60 %~80 %. The models are printed by Ti-6Al-4V powders. The morphology of the printed porous structures are examined by OM and SEM. Results show that only minor geometric deviation between the designed CAD pattern and the printed samples.
