Several high-tech products are reaching their operational limits. For example, the microelectronics industry is facing a growing demand for compact 3D architectures and reduced power consumption, while the aerospace industry is looking for lighter, more rigid and electrically conductive materials to lighten its devices. A very promising solution is to capitalize on the incredible properties of certain micro or nanoscopic materials (1 billionth of a meter) and incorporate them into plastics to form significantly improved composites. Additive manufacturing, or three-dimensional (3D) printing, of composites is a grouping of different shaping processes that allows the fabrication of structures through robotic deposition of material by means of a computer model. This technology is a very promising avenue for the implementation of many mechanical and aerospace systems. My work focuses on the development of advanced composite materials offering multiple functionalities (where multiple properties are desired for a given application) for additive manufacturing. On the manufacturing side, I will continue my original work on the printing of complex freeform 3D structures (without support material) and develop a multi-material printing platform compatible with my different composites of various properties (mechanical resistance, electrical conductivity, piezoelectricity: generation of electric charges when deformed, etc.). On the material side, I will create new types of composites that offer innovative features while remaining compatible with efficient green processes. Numerical simulation tools will also be developed to predict the properties of not only the composites, but also of the printed parts. My research pushes the boundaries of additive manufacturing and allows the creation of systems with properties and geometries that are not achievable with even the most advanced commercial 3D printers on the market. The expected benefits are (1) the complete development of a 3D freeform manufacturing method compatible with a wide variety of materials and applications, (2) the printing of a new type of fully printable sensor made of material composites for mobile devices where electrical energy is restricted (cell phone, smart clothing), (3) the creation of green materials and processes that are less polluting and innovative. These discoveries will benefit several academic collaborators for future projects, and industrial partners mainly working in the aerospace, microelectronics and biomedical fields.

几种高科技产品正在达到其运营限制。例如，微电子行业面临着对紧凑型3D体系结构的需求不断增长，而动力消耗降低，而航空航天行业正在寻找更轻，更刚性和导电的材料来减轻其设备。一个非常有前途的解决方案是利用某些微型或纳米镜材料的令人难以置信的特性（10亿米中的十亿个），并将其纳入塑料中，以形成显着改善的复合材料。复合材料的添加剂制造或三维（3D）打印是由不同塑料过程组成的分组，可以通过计算机模型通过机器人沉积来制造结构。这项技术是实施许多机械和航空航天系统的非常有希望的途径。我的工作着重于用于增材制造的高级复合材料的开发（提供多个功能（在给定应用程序中需要多个属性）。在制造方面，我将继续我的原始工作，以打印复杂的Freeform 3D结构（没有支持材料），并与我的各种特性的不同复合材料（机械电阻，电导率，压电性：变形时的电荷产生）相兼容的多物质打印平台。在材料方面，我将创建新型的复合材料，这些复合材料提供创新功能，同时与有效的绿色过程兼容。还将开发数值模拟工具，以预测复合材料的属性，还可以预测印刷部分的属性。我的研究推动了增材制造的界限，并允许创建具有属性和几何形状的系统，这些系统甚至是市场上最先进的商业3D打印机也无法实现的。预期的好处是（1）与多种材料和应用兼容的3D自由形式制造方法的完整开发，（2）印刷一种新型的完全可打印的传感器，该传感器是由限制电能的移动设备材料复合材料制成的（手机，智能服装），（3）绿色材料和工艺的创建和创新和创新。这些发现将使几个学术合作者在未来的项目中受益，而工业合作伙伴主要在航空航天，微电子和生物医学领域工作。
