Additive manufacturing for electronics is one of the world's fastest growing technologies in recent years. This new and upcoming technology has facilitated many innovative applications and high commercialization of metallic nanoparticle inks. A robust and novel induction sintering technique is proposed to solve the major challenges faced by the current existing sintering techniques in sintering metallic nanoparticle inks. The induction sintering process is a noncontact selective sintering process, in which only electrically conductive presintered printed patterns are heated up by alternating electromagnetic field through eddy current losses. It is also more energy‐efficient and effective as compared to thermal sintering since the induction sintering process only heats the electrically conductive printed patterns rather than the entire substrate. The electrical resistivity of the induction‐sintered printed pattern is measured to be 1.98 × 10−8 Ω m, which is ≈81% bulk conductivity of silver. This research breakthrough hence has the potential to overcome the challenges faced in additive manufacturing for electronics, in which printed patterns with high electrical conductivity can be fabricated on flexible substrates.

聚酰亚胺基底上银纳米粒子油墨的感应烧结
电子增材制造是近年来世界上增长最快的技术之一。这项新的和即将到来的技术促进了金属纳米粒子墨水的许多创新应用和高度商业化。为了解决当前烧结金属纳米颗粒油墨中现有的烧结技术所面临的主要挑战，提出了一种鲁棒且新颖的感应烧结技术。感应烧结过程是一种非接触式选择性烧结过程，其中只有导电的预烧结印刷图案通过涡流损耗引起的交变电磁场被加热。与热烧结相比，它还具有更高的能源效率和效率，因为感应烧结过程仅加热导电的印刷图案，而不是整个基板。感应烧结印刷图案的电阻率经测量为1.98×10-8 Ω米，这是银的≈81％体积电导率。因此，这项研究突破具有克服电子增材制造所面临的挑战的潜力，在电子增材制造中，可以在柔性基板上制造具有高电导率的印刷图案。
