Where to find information on 'fast' or 'professional' 3D printers? I work for a company that makes items from plastics.
Many or our current runs are between 500 and 5000 copies, but knowing the company, if we find a good method to do smaller runs, they are willing to see if it is a good commercial option.

At the moment we do use several different methods but the technical people are not yet looking into 3D printing.

While I am not sure printing is the right option just yet, I would be surprised if it will not be in the future.

At this time I am interested in finding information to convince the tech people to look into the abilities of printers and what would impress them to look further would be printers that can produce in short times or at multiple stations so the overall run will be relatively short term.
Our current items are mostly simple in shape, (disks with relief print) and small in size (no bigger than a 2 pound coin).

Do you know an online magazine where the tech people can look or can you suggest a (few) printer(s) to look at right now?
Links to online general information or names to search for will be great.

Knowing our current bunch of tech people they will likely prefer commercial available printers but proven 'home build technology' might be useful as well.
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

If you have any questions and/or I got anything wrong, please notify me.
