摘　　要：金属3D打印往往存在设备昂贵、生产研究门槛较高的问题。本研究根据选区激光熔化技术,利用30W小功率光纤激光打标机对金属锡粉进行3D立体打印,探究适用于小功率光纤激光打标机的合适参数。本研究分别以不同参数打印金属线条、金属实心块,研究不同参数下锡粉的成形规律及特点,最后采用堆叠打印,打印出复杂工艺品。实验结果表明,相较于矢量图,位图模式下打标的金属成型效果更好。综上,锡粉3D打印的最佳参数为位图模式下扫描次数3次、扫描速度90mm/s、激光功率80%、焦距145mm、铺粉层数15层。采用本研究方法打印的锡粉3D打印成品呈现金黄色金属光泽,有明显的立体感,成形效果较好,可以作为工艺品展示。Metal 3D printing often has the problems of expensive equipment and high production and research barriers.In this study,based on the selective laser melting technology,the metal tin powder was 3D printed by a 30W low-power fiber laser to study the appropriate parameters suitable for printing tin powder by a low-power fiber laser.Metal lines and solid metal blocks were printed with different parameters,and the forming law and characteristics of tin powder under different parameters were studied.Finally,complex handicrafts were printed in stacks.The experimental results showed that compared with vector graphics,the metal forming effect of bitmap scanning is better.To sum up,the best parameters of tin powder 3D printing are 3 scans in bitmap mode,scanning speed 90mm/s,laser power 80%,focal length 145mm,and 15 powder layers.The tin powder 3D printed by this study method presents a golden yellow metallic luster,has an obvious three-dimensional sense,and a good forming effect,which can be displayed as a handicraft.
