[QUOTE="Prosthodontics, post: 160381, member: 7077"] Interesting that this is already on the market in the US. I have at my disposal a SLM machine at the University. We are investigating ways to commercial selective metal sintering. I agree the finish of SLM is not as good as milling but I suspect the added roughness is probably good of added retention of porcelain especially in NP cases where oxide formation can be an issue? In the last few years, some good studies have emerged on SLM printed frameworks in terms of physical strength and fit and as alluded by other posters, they are definitely better fitted and also with more uniform grain formation -> increased tensile and flexural strength than traditional casting technique. I will be interested to see how Bego or Argen offers printed HN or N metals. I imagine they may have a few of these printers available for each alloy as cleaning the conduits of the machine from 1 material to another takes 1 whole day. Tonight we are printing an full-arch implant frame and some STL of natural teeth as a trial. Fingers crossed. [/QUOTE]
