Novel 3D printer

The invention relates to the field of printers, in particular to a novel printer. A novel printer comprises a printer bottom plate, a wire winding device is installed on the printer bottom plate, a wire stroking device is installed on the wire winding device, a wire winder is nested below the wire stroking device, an inner rotating shaft is connected to the wire winder, a wire fixing groove is formed beside the inner rotating shaft, a wire clamping device is connected beside the wire fixing groove, and a wire clamping device cylinder is arranged in the wire clamping device. A plurality of wire clamping shafts are installed on the wire clamping device cylinder, and a plurality of wire clamping objects are installed on the wire clamping shafts. According to the invention, a wire winder in the wire winding device is matched with a wire stroking device to straighten consumables and then feed the consumables into the extruder, so that the phenomenon that the consumables cannot be fed into the extruder because the
