Non-resin 3D printers and materials

[MetalMachine]

SLA and DLP printers using resins are the most common types in dental laboratories. I bet only a few labs have SLS, SLM, BJ or other printers but I'm curious to hear experiences anyway. Or if you outsource printed e.g. titanium bridges, partial framework, sleeping devices I would love to hear if you are happy with the quality, fittings and materials. I remember some metal prints had quality issues few years back in Europe. Does anyone provide printed zirkonium oxide or other ceramics yet?

If you aren't familiar with terms:

1. Stereolithography (SLA)
2. Digital Light Processing (DLP)
3. Fused deposition Modeling (FDM)
4. Selective Laser Sintering (SLS)
5. Selective Laser Melting (SLM)
6. Electronic Beam Melting (EBM)
7. Laminated Object Manufacturing (LOM)
8. Binder Jetting (BJ)
9. Material Jetting (MJ)
