Abstract
Selective laser melting (SLM) enables the utilization of complicated lattice structures in metallic components. To exploit this capability, it is important to understand the structural properties of these lattices. Topological variations in lattices are diverse, however, only a few are suitable for SLM since some lattices require supports during manufacture while others self-support. Difficulties associated with the removal of these supports and their detrimental effects on surface finish makes the latter group better suited for SLM. In this work, we investigate the structural properties of some self-supporting unit cells via a finite element study and show that the performance of a lattice structure is largely dependent on the topology of the unit cell. Variants of the gyroid and face centred cubic unit cells performed better than body centred cubic cells. This was also observed when lattices, made of repeating unit cells were compared.
