I have the Nobel 1 for over a year. Had some issues it. The file sizes are limited so dont think about making anything large. Also the resins are RFID tagged on the bottles and the software is very closed source. Have not been able to get a separate tray for separate resins from the company. The trays and platform have issues of proper adherence and release for parts. You will mess with it a lot before getting a usable result. For exactness of parts the resins they have compress and shrink. So dont expect exact tolerances. The Formlabs is a lot more community supported and lots of solutions to get the results you want. I wish I had gone the Formlabs route instead of the Nobel 1 in all frankness.
