绘图仪式高速激光树脂3D打印设备研制

摘要

In order to further explore the realization method of 3D printing, and to get a promotion in the precision and efficiency, based on the structure of the plotter, combined with the stereolithography (SLA) technology, a new stereolithography plotter ( SLP) design was presented for 3D printing with photosensitive resin. Its movement structure was similar with the plotter, and laser focus part did xy two-dimensional motion directly. Its focus length was much shorter than that of SLA, so its power requirement of light source was lower. Compared to the SLA and digital light processing ( DLP), its work field can be extended more easily.%为了进一步探索3D打印实现方法,提高精度和效率,在绘图仪的结构基础上,结合光固化立体打印技术(SLA)的原理,设计了一种用于树脂材料的绘图仪式3D打印设备(SLP),它拥有绘图仪式的运动结构,激光及聚焦部分可直接做xy二维运动. 相对于SLA技术,SLP大幅减小了焦距,所以对光源的要求更低. 相比SLA和数字光处理技术(DLP),SLP加工幅面更容易扩大.
