At present,there are only a handful of processes that can achieve high-precision 3D printing,among which the surface projection micro-stereolithography PμSL process is one of them.This process is represented by Shenzhen Mofang Material Technology Co.,Ltd.,which has developed a variety of models and realized commercial production,providing high-precision machining solutions for many large companies at home and abroad.The picture below shows the magnetic gripper and the magnetic spring array structure processed by the company’s 10um precision equipment nanoArchS140 by doping the high-strength toughness resin with a magnetic powder particle mass ratio of 20%.
目前,能够实现高精度3D打印的工艺屈指可数,其中面投影微立体光刻PμSL工艺是其中之一。该工艺以深圳摩方材料科技有限公司为代表,已经研发出多款型号机型,并且实现商业化生产,为国内外多个大型公司提供高精密加工方案。下图是该公司10um精度设备nanoArchS140通过在高强度韧性树脂中掺杂磁性粉末颗粒质量比20%加工的磁性抓手以及磁性弹簧阵列结构。
