You ever have one of those spools that has just enough filament left that it’d be a waste to throw away, but not enough to print anything useful? You could start a print, then hang around and pause the printer to swap a roll, but who has time for that? Now there’s another option, the Sunlu FC01! The FC01 heats up to 185º C to fuse your filament together and uses Teflon tubes that go over the filament while heating to make sure the joint is round. Fuse different color filaments to make your own color changing spool for fun!
