3D Printing: Cellular Composites

Previous Next

Materials scientists at Harvard University have created lightweight cellular composites via 3D printing. These fiber-reinforced epoxy composites mimic the structure and performance of balsa wood. Because the fiber fillers align along the printing direction, their local orientation can be exquisitely controlled. These 3D composites may be useful for wind turbine, automotive and aerospace applications, where high stiffness- and strength-to-weight ratios are needed.
