In this paper are presented some researches concerning the recycling process of Co-Cr powders that is used by the sintering process DMLS. Direct Metal Laser Sintering process is an additive laser manufacturing technology and is used in different domains like tooling, aerospace, medicine and auto. In the tooling domain, Co-Cr alloy powder is sintered by DMLS process, using a Phenix Systems machine, for obtain different mold prototypes. Co-Cr alloy powder presents good mechanical and corrosion properties. The SEM an...

In this paper were realized some researches concerning the grinding process of plates used by the sintering process DMLS. This plates are used in Direct Metal Laser Sintering process like support necessary for the powder deposing and for the final pieces realized by sintered process. The material used in DMLS process necessary for dental crowns manufacturing is a Co-Cr alloy. Co-Cr alloy is a super stainless steel with good mechanical and corrosion resistance. The material used for plates is a Fe-15%Cr martensitic...
