Abstract

Additive manufacturing (AM) has enabled designers and engineers to produce increasingly complex geometries and components. Selective laser melting (SLM) manufacturing has been particularly instrumental in this. Through careful control of the processing parameters and build angles and supports structures, manufacturers can now realise their theoretical design concepts more readily and produce complex structures such as lattices. Lattice structures have the capacity to generate unique mechanical, electrical, thermal and acoustic properties. There has been a large amount of information published relating to the mechanical properties of these structures. Generally, the mechanical testing of SLM lattices has been performed under compression. This report addresses a specimen design and testing approach for the measurement of the tensile mechanical properties of lattice structures.
