Additive manufacturing has gained substantial public attention through 3D printing while its 2D counterpart is already an established large scale industrial production process for certain printable electronics including organic light emitting diode displays and flexible photovoltaics. Printable electronics for applications with moderate integration densities are consistently evolving through new printing process flows but first and foremost through the development of new functional inks for conductors, semiconductors, insulators and advanced functionalities. The aim of this project is to design and to build a modular roll-2-roll printing setup that allows for the integration of different electronic functions for applications in flexible electronics such as smart tags or wearables. These electronics functions will comprise a battery, an RF antenna, some logic and non-volatile resistive RAM. In order to conceive a prototype, a modular design also able to accommodate third party solutions is suggested that includes the complete fabrication process from the surface modification for adapted wettability, the transfer of ink itself including an optical controlled alignment unit in feedback mode, several options for sintering and a lamination unit to protect the device structure against mechanical wear. The project relies on the competence of the industrial partner in the design and construction of deposition technique with existing experience in roll-2-roll processing and the experience of the academic partner who has demonstrated the first fully ink-jet printed non-volatile resistive random access memory. Both partners have already successfully collaborated on various occasions and have external collaborators from Saskatchewan and Germany to assist with dedicated aspects of printing processes and the structural and chemical characterization of the printed structures.

增材制造通过3D打印获得了大量的公众关注，而其2D对应物已经是某些可打印电子产品（包括有机发光二极管显示器和柔性光电子产品）的既定大规模工业生产工艺。用于中等集成密度应用的可印刷电子产品通过新的印刷工艺流程不断发展，但首先是通过开发用于导体，半导体，绝缘体和高级功能的新功能油墨。 该项目的目的是设计和构建一个模块化的卷对卷打印设置，允许在智能标签或可穿戴设备等柔性电子产品中集成不同的电子功能。这些电子功能将包括电池、RF天线、一些逻辑和非易失性电阻RAM。为了构思原型，提出了也能够容纳第三方解决方案的模块化设计，其包括从用于适应润湿性的表面改性的完整制造过程、油墨本身的转移（包括反馈模式中的光学控制对准单元）、用于烧结的若干选项以及用于保护装置结构免受机械磨损的层压单元。 该项目依赖于工业合作伙伴在设计和建造沉积技术方面的能力，以及在卷对卷处理方面的现有经验和学术合作伙伴的经验，他们展示了第一个完全喷墨打印的非易失性电阻随机存取存储器。这两个合作伙伴已经在各种场合成功合作，并有来自萨斯喀彻温省和德国的外部合作者，以协助印刷工艺的专门方面和印刷结构的结构和化学表征。
