Adaptation of novel 3D printing technologies with embedded printed electronics is a potentially transformative opportunity in the development of multifunctional 3D structures. The printing of conductive interconnects, passive and active components, sensors, actuators, batteries and antennas within 3D-printed structures has been a growing focus of the additive manufacturing sector. The University of Calgary team has recently developed a unique hybrid conductive ink that can be easily printed during the 3D printing process by a pause and deposit process. New hybrid conductive inks with proprietary additives that possess self-healing characteristics when exposed to intense pulsed light (IPL) or internal joule heating will be investigated. This new approach can transform the manufacturing of smart devices that can change themselves. The system will sense and adapt to various stimuli, respond, and then revert to its original state when the stimulus is addressed or removed. Smart functional materials and devices have many advantages, including selectively tunable functionalities, their ability to simultaneously act as sensors and actuators, their flexibility to adapt to environmental conditions, their potential for miniaturization, and their ability to be controlled. Early warning of problems will be possible, as will adaptive responses to intelligently address unforeseen circumstances. Enhancements to many products can produce better performance of their functions through better control and improved accuracy and by enabling preventative system maintenance prior to catastrophic failures. By exploring a rapid but precise integrated 3D printing technology, we can fully utilize multifunctional aspects of 3D systems. This would enable new commercialization opportunities for a variety of applications. The research will benefit Alberta and Canada by providing economic, social, and environmental benefits and will facilitate training of HQP with a variety of professional and technical skills.

将新型3D打印技术与嵌入式印刷电子产品相结合是多功能3D结构开发的潜在变革机会。在3D打印结构中打印导电互连、无源和有源组件、传感器、致动器、电池和天线一直是增材制造领域日益关注的焦点。卡尔加里大学的团队最近开发了一种独特的混合导电墨水，可以在3D打印过程中通过暂停和存款过程轻松打印。新的混合导电油墨与专有添加剂，具有自我修复的特性，当暴露于强脉冲光（IPL）或内部焦耳加热将被调查。 这种新方法可以改变可以改变自己的智能设备的制造。该系统将感知和适应各种刺激，做出反应，然后在刺激被处理或移除时恢复到其原始状态。智能功能材料和器件具有许多优点，包括选择性可调的功能，它们同时充当传感器和致动器的能力，它们适应环境条件的灵活性，它们的小型化潜力以及它们的控制能力。问题的早期预警将成为可能，智能地应对不可预见情况的适应性反应也将成为可能。许多产品的增强功能可以通过更好的控制和提高的准确性以及在灾难性故障之前进行预防性系统维护来实现更好的功能性能。 通过探索快速但精确的集成3D打印技术，我们可以充分利用3D系统的多功能方面。这将为各种应用提供新的商业化机会。这项研究将使阿尔伯塔省和加拿大受益，提供经济、社会和环境效益，并将促进HQP的培训，使其具备各种专业和技术技能。
