Technical Problem

[0003]当前,SLM技术领域采用的是固定式的光学系统,在超大幅面的多振镜系统的设备应用中,需要配合更多的激光和扫描振镜来增加打印幅面,这会面临多激光相互干涉的风场问题,影响成形效率和质量,并且采用过多的振镜会带来一定的技术上的复杂性和经济上的不友好

Benefits of technology

[0025]本发明提出了一种光学模块运动控制方法,该方法顺应了增材制造设备日益大型化的发展趋势,通过可移动光学系统实现激光束的自由移动。这一创新打破了传统SLM技术在幅面方面的限制,使得更大尺寸的零件打印成为可能。相较于传统打印方法,此控制方法用更少的光学模块打印更大尺寸的零件,显著提高了设备的打印效率,同时降低了设备成本。同时,本发明所提供的光学模块运动控制方法采用了独特的光学模块排列方式,例如3×2阵列或3×3阵列,利用该阵列方式,光学模块可以根据扫描截面出光打印,以最后列为主,当最后列出光结束矩阵式光学模块前进,同时根据其他列光学模块打印结果判断前进距离,实现激光束位置、角度和出光时间的灵活调整。这种出光和前进方式使得激光扫描效率更高,进而提高了零件的打印速度和加工效率。
