摘要
基于短波长(532 nm)纳秒脉冲激光器,探索了若干脉冲激光加工参数(如:峰值功率、单脉冲能量、搭接率、扫描角度)对金属材料3D打印技术成型工艺的影响,并初步探索了基于脉冲激光实现多元材料涂覆的工艺方法。研究发现:相较于连续激光金属3D打印,此次试验发现通过脉冲激光的激波现象,可显著改善3D打印成型件的组织形貌;通过在基材表面激光刻蚀微纳结构,可实现多元材料的结合。
Based on the short-wave(532 nm) nanosecond pulse laser, this article explores the influence of several pulse laser processing parameters(such as peak power, single pulse energy, overlap rate, scanning angle) on the molding process of metal 3 D printing technology, and preliminarily studies the process method of multi-material coating based on pulse laser. Compared with continuous laser metal 3 D printing, this research finds that the shock wave phenomenon of pulse laser can significantly improve the structure morphology of 3 D printing parts;It can realize bonding of multiple materials by versus of laser etching the micro-nano structure on the substrate surface.
