单驱动双色3D打印机喷头
本技术属于3D打印
，特别是涉及一种单驱动双色3D打印机喷头。
技术介绍
3D打印机逐渐被人们所认知，并逐步广泛的应用到各个行业。然而，现有的3D打印机基本是单色单电机单喷头，需要打印两色以上时就需要多台打印机互换，很是繁琐，相应的就出现了打印双色3D打印机。但是，现有的双色3D打印机采用双电机双喷头，一个电机对应一个喷头，才能够完成双色打印，而采用双电机则必然增加了喷头的重量，从而导致震动，整体结构的稳定性差，不但影响打印质量，同时打印的速度也会减慢。此外，双喷头3D打印机工作时，每个喷头对应一种颜色的打印材料，打印过程中要变换颜色时，就要切换对应不同颜色的喷头，切换单喷嘴的工序繁琐，效率低。在进行3D打印时，往往一个零件的不同部位，需要的性能不一样，一个零件的不同部位需要的颜色也不一样。目前实现这些要求比较困难，而且现有打印机在双色过渡时还会出现缝隙，导致模型表面精致度不高。
