Abstract

Plate lattices are an emerging class of lightweight mechanical metamaterials that exhibit superior mechanical properties. The unique architectures of plate lattice metamaterials are regarded as the origin of achieving such advanced performance, but they lead to the difficulty of powder removal after the powder-bed-based additive manufacturing process. In this chapter, plate lattice metamaterials with half-open-cell topology are proposed and fabricated via the laser powder bed fusion technique. To investigate their mechanical performance ...
