Abstract
A 3D printing head having a carrier, a pair of nozzle assemblies, a swing arm and a driving mechanism is provided. The nozzle assemblies are arranged on the carrier. Each nozzle assembly has a nozzle and a reset elastic member. Each nozzle is connected to the carrier and up-down movable relative to the carrier. The reset elastic members are connected between the carrier and the respective corresponding nozzles. The swing arm is pivoted on the carrier and able to swing one end thereof between the nozzles to selectively press one of the nozzles down. The driving mechanism is connected with the swing arm to rotate the swing arm. The swing arm can be rotated by the driving mechanism to press the operated nozzle down for printing, and a height difference between the nozzles is thereby formed to prevent the product from being scratched by the idle nozzle when printing.
