My library has a Prusa derivative and several Dremel commercial machines, all running PLA filament. The Dremels are not bad for FDM machines, but the RFID-equipped proprietary spools are not ideal IMHO. On one hand, they tell the machine what it is using so it can auto-adjust its settings and simplify setup. The quality seems good, too. On the other hand, you're locked into a proprietary supply chain.
