Additive manufacturing (AM) encompasses a range of processes, each capable of producing near-net-shape 3D components by accumulating discrete 2D layers. AM has received a rising interest from various industries who look to benefit from the many advantages that AM can offer, including geometrical optimisation, decreased material wastage and shorter lead times over traditional methods. In metallic AM systems, microstructure and subsequent mechanical properties of builds are dependent on the process parameters, as well as geometrical factors such as component height, giving a locational dependency. Therefore, variation in properties throughout an AM component can render conventional mechanical testing unsuitable. Small Punch (SP) testing is a small-scale mechanical test methodology capable of producing a tensile, creep or fatigue-like response. The ability to extract small-volume samples from distinct locations makes this test technique ideal for AM-materials. This paper will validate the use of SP testing in estimating the mechanical response of AM-materials.
