"Additive Manufacturing (AM) techniques are seeing increasing use for the fabrication and repair of commercial engineered components, and could offer significant advantages over traditional manufacturing methods for defence use. However, the field of AM is broad, and it can be difficult for the non-expert to separate the hype from reality. Parts used for defence applications are often critical and operate in demanding environments, and so knowledge of AM capabilities is necessary in order to choose the best option. This Scientific Report summarizes the current state of the art of commercially available AM techniques, focusing on their applicability and usage in defence structural applications. Particular attention is paid to the variety of material feedstocks available and the resulting mechanical properties, anisotropy, residual stresses, and fatigue and fracture performance of each technique. The relative pros and cons of each technique from a defence standpoint are also addressed. This report thus offers useful guidance to the novice and expert alike when considering AM for defence structural components"--Abstract.
