The utility model discloses a multi-nozzle printer, which comprises a printing device and a rack. The printing device comprises a carrier plate, a proximal motor, a proximal nozzle and at least one distal nozzle. The proximal nozzle is provided with a proximal wire, and the distal nozzle is provided with a distal wire. The proximal motor, a proximal nozzle and a distal nozzle are fixed on the carrier plate, and the output end of the proximal motor is near to the proximal nozzle. The end motor drives the wire in the proximal nozzle to move; the frame is equipped with a distal motor, which clamps the distal wire to transport to the distal nozzle. By installing a proximal motor on the printing device, the printer can print at the proximal end to complete the base printing of the printed parts. At the same time, a plurality of distal motors are set on the rack, so that when the printing device can achieve multi-line synchronous printing, the printing time is greatly shortened, without changing the wire, the weight of the printing device is not increased, and the load of the displacement mechanism is not increased, thus ensuring the printing. Printing speed and service life of displacement mechanism.

一种多喷头打印机
本技术涉及3D打印机,具体为一种多喷头打印机。
技术介绍
目前,在3D打印机中,线材的输送方式通常有2种:第一种是在打印装置上设置挤出电机,通过挤出电机夹取以滚轮带动线材进入到喷嘴内,这种线材的输送方式可以称为近端送线,即挤出电机是位于打印装置上,能够带动多种线材(即使是软料线材,如热塑性聚氨酯弹性体PTU等),打印精度较高,其缺点是挤出电机固定在打印装置上,打印装置的负重较高,则带动打印装置移动的位移机构则要承担更大的载荷,位移机构容易损坏;若是需要多个喷嘴进行同时打印,则需要在打印装置上设置于喷嘴数量对应的挤出电机,导致打印装置负重过大,位移机构运动缓慢且容易损坏。第二种是将挤出电机设置在打印机机架上,通过挤出电机带动线材移动进入到喷嘴内,使得挤出电机远离打印装置,这种打印方式称为远端送线,打印装置整体重量下降很多,降低了位移机构的负重,以延长整机的使用寿命降低损坏几率;但是同样带来一系列问题:由于挤出电机外装,导致挤出的线材与所要到达的喷嘴之间行程较长,柔软的线材是难以对准喷嘴的,必须是具有一定硬度的线材,因此对于线材的材料是有限定的,无法 ...
