摘要： There is disclosed a multi-material extruder and extrusion method for 3D printing, and more particularly to an apparatus and method that is adapted to extrude a wide range of materials for printing 3D structures. In an aspect, the apparatus comprises a frame adapted to receive a removable syringe or cartridge with a depressible piston in an extended position, the syringe or cartridge containing material to be extruded. An extrusion motor is under the control of an extruder logic module to determine how quickly the piston of the syringe or cartridge is to be depressed to achieve a desired rate of extrusion of the material. A flexible length of tubing connects the tip of the syringe or cartridge to an extruder nozzle, which nozzle is mounted to a stylus which may be hand-held or mounted to a chassis of a 3D printing device. A feedback signal is used to provide a feedback signal to the extruder logic module to determine the rate of extrusion of material. The syringe or cartridge may include a label containing information on the type of material in the syringe or cartridge, and one or more extrusion parameters to be used with the material in the syringe or cartridge.
