Enclosed Qidi Tech Plus 4 3D printer has a silver and black exterior. This unit features a 305 x 305 x 280 mm build volume with a heated print bed. It includes a front-mounted touchscreen control panel, a fully enclosed chamber with a clear top and front door, and a rear-mounted filament spool holder. I barely used this printer, because I have a Creality multi color printer, and I just bought a Snapmaker U1so I’m getting raid of this. It work perfectly fine. No issues. I’m down to negotiate.
