Compressive Behaviour of Additively Manufactured Lattice Structures: A Review

Additive manufacturing (AM) technology has undergone an evolutionary process from fabricating test products and prototypes to end-user products—a major contributing factor this is the continuing research development in area. AM offers unique opportunity fabricate complex structures with intricate geometry such as lattice structures. These are made up of struts, unit cells, nodes, being used not only aerospace industry, but also sports owing their superior mechanical properties performance. This paper provides a comprehensive review performance both metallic non-metallic structures, focusing on compressive behaviour. In particular, optimisation techniques utilised optimise examined, well primary factors influencing lattices, failure mechanisms/modes. Important limitations regarding structure fabrication identified review, while paucity literature material extruded metal-based discussed.
