The UM3 takes "3mm" filament which actually means either 2.85 or 2.9mm nominal diameter filament.
The UM3 prints any brand of PLA, ABS. It prints most filaments as long as they are "3mm". Notice I put that in quotes because it's actually a bit smaller than 3mm.
The bed can just barely get up to 100C and the nozzle can get up to 280C no problem. So any filament that doesn't need hotter than those temperatures will be fine in the UM3.
You can make your own custom temperature settings so they will work. The only thing that will not work is the filament detection systems because the other filaments will probably not have a nfc tag
