摘要
分析FDM技术原理的3D打印机的工作原理及技术特点,选定XYZ型3D打印机作为本文研究的实验样机。探究实验样机中Z轴传动原理,确定直线光轴在其轴向起到传动导轨的作用。通过直线光轴与Z轴打印平台的几何关系,分析在极值层厚下光轴直线度误差对于Z轴定位精度的影响,通过计算并最终得出结论。
The working principle and technical characteristics of 3D printer for analyzing FDM technology principle are ana- lyzed, and XYZ type 3D printer is selected as the experimental prototype of this paper. The principle of Z shaft transmission in experimental prototype is explored, and the role of linear optical axis in the axial direction is determined. Through the geometric relationship between the linear optical axis and the Z axis printing platform, the influence of the linear degree error of the opti- cal axis on the positioning accuracy of the Z axis under the extreme thickness is analyzed and the conclusion is finally obtained.
