一种新型多色3D打印机结构及其控制系统设计

Mechanical Design and Control of a New Multicolor 3D Printer

目前FDM 3D打印机存在成型件颜色单一的缺陷,为了解决这一问题,设计了一种多色打印机换丝机构,并对标准G代码指令进行了修改,通过三进一出挤出方式实现单喷嘴彩色丝料的挤出打印成型。通过打印实验,验证了所设计的多色打印机换丝机构及控制系统的有效性。

At present,FDM 3D printer has the defect of single color of printed parts.In order to solve this problem,the paper designs a multi-color printer wire changing mechanism,modifies the standard G code instruction,and realizes the extrusion printing molding of single nozzle color silk through three in one out extrusion.Through printing experiments,the effectiveness of the multi-color printer wire changing mechanism and software system designed in this paper is verified.
