Beschreibung
Zusammenfassung:	A single-motor extrusion head using double materials for extrusion comprises a single-motor extrusion device. A double-head heating device is arranged below the front end of the single-motor extrusion device, and a movement device is connected below the rear end of the single-motor extrusion device. One end of each of two printing wire rods symmetrically penetrates into the single-motor extrusion device and the two sides in the double-head heating device from the two sides of the top end of the single-motor extrusion device, and the movement device is connected to a guide rail of a printer. One-way needle bearings in different directions are mounted on a driven gear set in the single-motor extrusion device, so that the extrusion head can use one extrusion motor, two materials can be selectively extruded by changing the rotating direction, a 3D target is constructed layer by layer, the overall size and mass of the extrusion head are reduced through the single extrusion motor, the inertia force of movement of t
