Abstract

Using additive manufacturing (AM) techniques for end user parts is quite attractive for performance enhancement and product customisation since designs are less constrained via this technique. The extent to which this could influence design is still to be determined. An interesting way to exploit AM capabilities for mechanical components is to embed lattice structures in such components. However, constraints inherent on some AM machines might limit the range of suitable lattices. For selective laser melting (SLM), supports are needed for features inclined at an angle lower than 45∘. This does imply that lattices without such features are better suited for SLM. Despite this constraint, a number of lattices can be made via the SLM technique. In this paper, we determine the structural properties of four of these self-supporting lattices via non-linear contact analysis. A minimal surface lattice show superior properties to those of the other three strut based lattices.
