I avoid buying 2d printers because they are so maintenance heavy... I use a 3D printer in a shared makerspace, where whoever has the most avialability takes on maintenance issues when they arise.

The Prusa mk4's we use are extremely reliable; most problems come down to users doing dumb stuff... or at least, doing risky stuff and not monitoring the print.

I find that I usually have some /kind/ of print I'm making (say, very hollow terrain pieces for tabletop wargames) get my printer settings dialed in over the course of a few failed prints, and then can print more of that kind of thing very reliably. In other words, good printer settings are project dependent, but can usually transfer reliably across simlar projects. And then I don't have to think much about the printer - it just does its thing.
