摘　　要：针对目前桌面级3D打印机普遍仅支持单色打印的问题,在熔融挤压堆积成型(Fused Deposition Modeling,FDM)并联臂单色3D打印机的基础上通过改进喷头结构、编写上位机控制软件,实现了一种无需更换喷头、耗材,无需后处理,可一次成型多色、渐变色的3D打印方案。将单进料—单挤出喷头改进为双进料—单挤出结构,通过上位机软件设置2种不同颜色耗材的送料比例,不同颜色和比例的耗材在加热块内熔融后再通过单喷头挤出便可打印出不同的颜色。上位机控制软件还具有自定义混色方案、混色效果预览的功能。As the current desktop 3D printer is generally monochrome,a kind of color mixing FDM（ Fused Deposition Modeling） 3D printer is designed with the improved hot-end nozzle and color mixing control software based on Lab VIEW. The color mixing 3D printer could achieve once printing of multicolor or gradient color 3D model without replacing the hot-end nozzle or supplies and without any post processing. The single in-single out hot-end nozzle is changed into dual in-single out hot-end nozzle,implementing the ratio setting and controlling of two color printing material by software. Then the multicolor could be generated by mixing two colors in different ratios. Besides, the software provides customized color mixing scheme and color mixing printing effect preview.
