Design and 3D printing of bioinspired composite materials Inspired by the toughness of the scales of the Polypterus Senegalus, we aim to produce multilayered multimaterial composites through 3D Printing. The aim is to design new inks for Direct Write with different mechanical properties. The superposition of inks with different properties allow for structure with superior resistance to concentrated loads. Y. Abderrafai |
