I studied drafting and design when hobby printers were just getting started, and most machines were industrial-grade. As a librarian, I've worked with Dremel's machines. They've all been FDM with filament spools, and I have no experience with resin. My issues most recently have been with failures in the hot end assembly. I'm willing to answer questions if you have any. Are you just printing from Thingiverse, or starting to work on 3D design yourself?
