Alumina microlattices with solid struts and different topologies were fabricated by the stereolithography 3D printing method. Mechanical analysis shows that specific stiffness and strength were highest for Simple Cubic lattices, followed by Octet Truss, then Kelvin Cell lattices. The mechanical prop...
