AI Technical Summary
⚠Technical Problem
During the 3D printing process, if the previous material is not completely withdrawn during material switching, the residue in the pipe will mix with the new material, affecting the printing effect.
⚗Method used
Design an extrusion device comprising a housing and a slidable extrusion assembly including a pusher and a cutter. The extrusion assembly moves to the discharge port to block the feed port, expelling residual material, and switches the feed port at the pusher to prevent material mixing.
🎯Benefits of technology
It effectively prevents material mixing, improves printing results, saves materials, is environmentally friendly and efficient, reduces waste, and increases printing efficiency.

Abstract
The application discloses an extrusion device, a 3D printer and a method for using the extrusion device. The extrusion device can include a housing, a material channel, a discharge port in communication with the material channel, a push port in communication with the material channel, and a plurality of feeding ports in communication with the material channel. Along the length direction of the material channel, the discharge port is located at one end of the material channel, the push port is located at the other end of the material channel, and each feeding port is located between the discharge port and the push port. The extrusion assembly is slidably connected with the housing, so as to be capable of moving in the material channel from the side where the push port is located towards the discharge port, thereby pushing the material in the material channel out of the discharge port and blocking each feeding port. This design solves the problem of mixing of two materials when switching materials.
