3D打印多色打印方法分析

Analysis on 3D Multi-Color Printing Methods

3D打印技术根据所用材料的状态及成形方法不同可以分为多个种类,其中,熔融沉积成形技术(FDM)应用最广泛。通过多年的3D打印经验以及3D打印技术在多色打印方面的发展,对采用熔融沉积成形技术(FDM)的3D打印机多色打印方法进行研究,得出这种打印机实现多色打印的四种方法,通过分析,总结出每种打印方法的优点和缺点,希望能为从事3D打印的工作人员起到一定指导作用。

Depending on the material status and forming method used for 3D printing, 3D printing technology can be divided into several types, among which Fused Deposition Forming Technology （FDM） is the most widely used. With years of experience in 3D printing and the development of multi-color printing, 3D printing methods using Fused Deposition Forming （FDM） technology are studied, and four multi-color printing methods by such printers are obtained. By analysis, advantages and disadvantages of each printing method are summarized, in the hope of playing a guiding role for those engaged in 3D printing.
