3D Printer Advice

It really depends on your patience level. There are people who are willing to take the time needed to use open source/DIY printers in a professional setting. The drawback in spending money on personnel to become acquainted with the machines, as opposed to simply buying an office friendly solution from Stratasys or the other AM companies.

That being said, I have had a lot of luck with my Solidoodle 2 pro. It's basically a metal version of the earlier RepRap machines. It took some time to get setup properly, but once it was dialed in it was the best business purchase I've ever made. In fact, I earned back the money I put into it in the first month. It was used extensively to prototype several variations of a (confidential) orthopedic instrument. The resulting prints were even low temp sterilized and used in a surgical setting!

Since then, there have been a glut of other home 3D printers. There are a lot of Chinese knockoffs of successful printers too.

If you are looking for ease of use and low cost, the "Cube" printers from 3D Systems look promising. I haven't used them, so perhaps someone else can confirm. The only hitch is that their filament uses a special cartridge that discourages the use of any brand of filament. On the older Cube machines people found a way to work around it, but I'm not sure if anyone has managed to do that with the new ones.

At my work we use a some Flashforges, a couple of Rigidbots, and a Makergear M2. The Makergear gives the best quality, but was harder to set up. The Flashforge printers are workhorses, but they seem to always need another replacement part. The Rigidbot extruders are not great, but we have gotten some good prints from them. I think if the extruder was replaced with a more reliable one, they would be very good printers. As they are right now they jam a lot.

I've taken a liking to delta style printers, and so am considering the Atom 2 or Royee II, as they are some new and fairly high quality printers. I would probably choose the Atom out of these two, in spite of the fairly limited number of supported materials.

This is probably the best guide that I have seen though: https://www.3dhubs.com/best-3d-printer-guide

3D printer that can manage up to 50 microns should / can be classified as industial 3D Pritners...I guess ts means which 3d printer have most detail prints right?

I use an afinia and a lulzbot Taz 4 at work. Both are great machines. The afinia is by far the easiest desktop printer to use for someone without a lot of tech experience. The software is super easy to use. However, the Taz is much more capable....
