Where to find information on 'fast' or 'professional' 3D printers?
Since your company specializes in small objects, SLA printers seem to be a good choice, since it has better detail but small printing area. However, SLA printers tend to require lots of post processing.

If you need a printer for rapid prototyping, you should be using FFF or FDM printers which don't need any post processing. At most, you could sand surfaces to have a smoother finish.

If you need fast printers on the other hand, Delta type printers could be something to look at. Kossel or Rostock printers are faster than standard XYZ printers/CoreXY printers.

As for magazines, Make Magazine features 3D printers and 3D prints if that's what you're looking for.

Terms you can look up online (this includes some names of popular printers): FDM printers, SLA printers, Kossel printer, Rostock printer, CoreXY printer, Prusa i3, Formlabs Form 2, Ultimaker
