Laser Powder Bed Fusion of Co-Cr: A Material Comparison
Laser Powder Bed Fusion (LPBF) of cobalt-chrome (Co-Cr) alloys has been recognized for producing parts exhibiting the strength and being devoid of defects typically associated with cast Co-Cr alloys. Therefore, such parts are considered safe and comparable to cast Co-Cr alloys for intraoral use. Sin...

Summary: | Laser Powder Bed Fusion (LPBF) of cobalt-chrome (Co-Cr) alloys has been recognized for producing parts exhibiting the strength and being devoid of defects typically associated with cast Co-Cr alloys. Therefore, such parts are considered safe and comparable to cast Co-Cr alloys for intraoral use. Since additive manufacturing offers the advantage of creating complex geometries, the use of this thermo-physical process in a controlled manner allows for the homogenous production of the complex geometries typically required for dental products. This paper compares the mechanical properties claimed to be achievable through LPBF by the powder supplier against real world mechanical properties as used in dental applications. This comparison will serve as a baseline from which the mechanical properties achieved can be further enhanced to suit other possible applications of Co-Cr. |
