Manufacture of Co-Cr dental crowns and bridges by selective laser Melting technology This paper presents the successful application of the selective laser melting technology in dental frameworks manufacturing from Co-Cr alloy using Phenix PM 100T Dental Machine over a production period of 14 months

Currently, one of the most important applications of the Selective Laser Melting (SLM) process is dental frameworks manufacturing. The objective of the present study is to analyse mechanical and microstructural properties of dental crowns and bridges manufactured by SLM technology from Co-Cr alloy using a Phenix PM 100T Dental Machine over a production period of 14 months. The obtained results show clearly a successful application of the SLM technology to the design and manufacture of dental crowns and bridges. Dental parts with adequate density, geometrical accuracy, mechanical properties, and microstructure have been produced. Based on regular analyses results, of initial Co-Cr powder materials and final crowns properties characteristics, one can conclude that the Selective Laser Melting Process is adapted to the manufacturing of dental parts in correlation with the required traditional standards. The good repeatability of the SLM process has been demonstrated.
