The utility model discloses a 3D printer head and a 3D printer, which comprises a nozzle, a feeding channel, a heating iron core, a heat insulation layer, a high frequency induction coil and a high frequency AC power supply, and the inside of the heating iron core is provided with a material outlet, and the nozzle is connected with the outlet channel; the heating iron core is covered with the heating core. The outer surface of the heat insulation layer is provided with a high-frequency induction coil, and the two ends of the high-frequency induction coil are electrically connected with the high-frequency alternating current power supply. The utility model uses a high frequency induction coil to heat the core of the heated iron. By heating the induction heating principle, the surface temperature of the heating iron core is higher than the existing resistance rod heating temperature, which makes the material selection of the printer material enlarging, and can select the printing material with higher melting point, and solve the heating of the FDM3D printer head. The temperature is not enough, the printing material selection scope is small.

一种3D打印机头及3D打印机
本技术涉及打印机领域,尤其涉及一种3D打印机头及3D打印机。
技术介绍
随着技术发展,FDM(FusedDepositionModeling,熔融沉积成型)3D打印机向着低成本的方向发展,步进电机控制技术与传感器技术,实现打印机喷头的精确运动与温度控制,可将丝状的热熔性材料进行加热融化,通过带有细微喷嘴的挤出机将材料挤出来。熔融的丝材被挤出后随即会和前一层材料粘合,一层材料沉积后工作台将按预定的增量下降一个厚度,然后重复以上的步骤直至工件完全成型。当前FDM3D打印机的打印材料主要为PLA(PolylacticAcid,聚乳酸)和ABS(Acrylonitrile–butadiene–styrenecopolymer,丙烯腈-丁二烯-苯乙烯共聚物)塑料,这是因为打印机内通过电阻棒进行加热,受限于现有技术中电阻棒的温度,使得打印材料的选择被限制在熔点在230度以内的材料,因此导致了FDM3D打印机头加热温度不够,打印材料选材范围小的技术问题。
