Although multiple-material additive manufacturing has progressed rapidly over the last few years, little progress has been made so far on the additive manufacturing of metal/polymer hybrid components due to significantly different material properties. In this study, we investigated the printing of hybrid metal (Cu10Sn) and polymer (PA11) objects through a proprietary multiple-material laser powder bed fusion (LPBF) system. Powder materials were delivered to the build platform through an ultrasonic vibration-assisted dispensing system. Several 2D Cu10Sn/PA11 structures were printed and demonstrated. The scientific mechanism underlying how the interaction between Cu10Sn and PA11 during laser scanning affected printing quality is discussed. In addition, the roughness of the printed Cu10Sn top surface was improved tenfold with the addition of small amount of PA11 powder. Finally, several 3D components consisting of hybrid stainless steel (SS 316 L), copper (Cu10Sn), and polymer (PA11) including entangling structures were printed and discussed. Potential applications of this technology are discussed.

尽管近几年来多种材料的增材制造取得了飞速的发展，但由于材料性能的显着不同，到目前为止，金属/聚合物杂化部件的增材制造进展甚微。在这项研究中，我们研究了通过专有的多材料激光粉末床熔合（LPBF）系统对混合金属（Cu10Sn）和聚合物（PA11）对象的印刷。粉末材料通过超声振动辅助分配系统输送到构建平台。印刷并演示了几种2D Cu10Sn / PA11结构。讨论了在激光扫描过程中Cu10Sn和PA11之间的相互作用如何影响印刷质量的科学机理。此外，通过添加少量的PA11粉末，可将印刷的Cu10Sn顶表面的粗糙度提高十倍。最后，印刷和讨论了由混合不锈钢（SS 316 L），铜（Cu10Sn）和聚合物（PA11）组成的几种3D组件，其中包括缠结结构。讨论了该技术的潜在应用。
