Resumo
This chapter seeks to compare the properties of samples manufactured by additive
manufacturing (AM) by the selective laser melting (SLM) technology and compare with
the precision casting (PC) processes using the Co-Cr-Mo (ASTM F75) alloy to manufacture
of dental prosthesis. This AM process can be manufactured three-dimensional
models by means of a laser beam that completely melts particles of powder deposited
layer by layer. However, it is still relevant to know the properties of: performance,
dimensional, mechanical and microstructural of this laser melting process and compare
with a convencional process. The results of mechanical evaluation showed that the SLM
technique provides superior mechanical properties compared to those obtained by the
PC technique. It is possible to verify that the consolidation by SLM technique results
in lower presence of porosity than PC technique. In addition, PC samples presented
a gross dendritic microstructure of casting process. Microstructural analysis of SLM
samples results in a characteristic morphology of layer manufacturing with ultrafine
grains and a high chemical homogeneity. In this way, the development of the present
study evidenced to improve the manufacture of customized components (copings)
using the SLM technology.
