Printed electronics based on graphene and related 2D materials (GRM) is a key research field with immediate application in flexible electronics, photonics, composites and rapid manufacturing. Printed and flexible GRM field effect transistors with mobility superior to flexible TFTs based on organic electronics, printed photodetectors with photoresponsivity in the range of 0.2mA/W , highly conductive (up to106 S/m) flexible electrodes have demonstrated the realistic potential of this technology. However, the control of reproducibility, large-scale printing as well as the research for new unexplored applications stimulates large part of research in this field.  In this talk I will overview the fundamental of graphene inks formulation focusing on the and the portfolio of reproducible and scalable manufacturability processes enabling future GRM-based printable and flexible (opto)electronic devices and composites. I will demonstrate cost-effective, up-scalable production of high concentration graphene inks with tailored properties (on-demand size, shape, number of layers and concentration). I will discuss realistic pathways to commercialization of GRM inks and demonstrate prototypes such as: inkjet-printed graphene thin-film transistors, flexible transparent touch pads and photodetectors. Finally, I will present my vision on manufacturability of flexible and wearable electronic and optoelectronic devices embedding the optical, electronic, mechanical and thermal functionalities of graphene, 2d crystals and their hybrid hetero-structures.
