增材制造电子产品，也称为印刷电子产品，对于预期的物联网（IoT）变得越来越重要。这就要求制造技术能够将各种纯功能材料和器件集成到不同的柔性和刚性表面上。然而，目前的油墨技术受到复杂和昂贵的油墨配方，油墨相关污染（添加剂/溶剂）和印刷材料来源有限的影响。因此，打印无污染和多材料的结构和设备是具有挑战性的。在这里，展示了一种利用纳米和微尺度定向激光沉积的多材料添加剂纳米制造（M-ANM）技术，允许打印横向和垂直混合结构和设备。这种M-ANM技术包括脉冲激光烧蚀放置在打印机头内的目标转盘上的固体目标，以原位生成无污染纳米颗粒，然后通过载气引导这些纳米颗粒流向喷嘴并到达基板表面，在那里它们被第二束激光实时烧结和打印。目标旋转装置以预定的顺序将特定目标与烧蚀激光束结合，在单个过程中打印多种材料，包括金属，半导体和绝缘体。利用这种M-ANM技术，可以印刷和表征各种多材料器件，如银/氧化锌（Ag/ZnO）光电探测器和银/氧化铝（Ag/Al2O3）混合电路。我们的M-ANM技术的质量和多功能性为新兴物联网提供了潜在的制造选择。
Additively manufactured electronics, also known as printed electronics, are becoming increasingly important for the anticipated Internet of Things (IoT). This requires manufacturing technologies that allow the integration of various pure functional materials and devices onto different flexible and rigid surfaces. However, the current ink-based technologies suffer from complex and expensive ink formulation, ink-associated contaminations (additives/solvents), and limited sources of printing materials. Thus, printing contamination-free and multimaterial structures and devices is challenging. Here, a multimaterial additive nanomanufacturing (M-ANM) technique utilizing directed laser deposition at the nano- and microscale is demonstrated, allowing the printing of lateral and vertical hybrid structures and devices. This M-ANM technique involves pulsed laser ablation of solid targets placed on a target carousel inside the printer head for in situ generation of contamination-free nanoparticles, which are then guided via a carrier gas toward the nozzle and onto the surface of the substrate, where they are sintered and printed in real-time by a second laser. The target carousel brings a particular target in engagement with the ablation laser beam in predetermined sequences to print multiple materials, including metals, semiconductors, and insulators, in a single process. Using this M-ANM technique, various multimaterial devices such as silver/zinc oxide (Ag/ZnO) photodetectors and hybrid silver/aluminum oxide (Ag/Al2O3) circuits are printed and characterized. The quality and versatility of our M-ANM technique offer a potential manufacturing option for emerging IoT.
