Building complex 3D micro parts
Currently, the mass manufacture of non-silicon micro devices cannot produce very complicated 3D parts and is not suitable for inorganic materials such as ceramics and metals. A mass market solution is required for producing very complex multifunctional 3D parts made from ceramics. Fulfilling this need was the aim of the 'Rolled multi material layered 3D shaping technology' (MULTILAYER) project, funded by the EU. This project used the concept of tape casting combined with advanced printing techniques for the mass fabrication of micro devices. The project developed a solution that involves cutting the design of the micro device into several different layers, which are individually structured and treated before being assembled. This technology places no limitation on the complexity of the part to be designed, which is important for the miniaturisation of micro-structured parts. In an effort to provide a reliable set of technologies, MULTILAYER first developed the technology platform needed for several fabrication routes. This novel platform was then evaluated for making different kinds of 3D multi-material products. A set of six demonstrators was then produced to showcase various applications and to validate the MULTILAYER platform. These were used to demonstrate the potential to address already existing and new markets, offering new products at extremely reduced costs. Now complete, the MULTILAYER project has resulted in a novel approach to the manufacture of microsystems in Europe, which also has the potential to open up new market sectors. Consequently, it will increase job opportunities in existing European companies while promoting the set-up of new high-tech firms.
