The Properties of Parts Produced by Additive Manufacturing

This chapter addresses the question of characterization test specimens, whose orientation with respect to the build direction and any post-treatments applied is essential, before characterizing the properties obtained. It describes a certain number of properties by comparing them, when possible, with those obtained from more conventional processes: static properties, resistance to fatigue, creep and corrosion. The chapter focuses on architectured materials that require special treatment and offers a wide range of properties. As with any manufacturing process, the characterization of the mechanical properties obtained in additive manufacturing requires the use of “representative” test specimens of the final process used for the target part, including any post-processing. The chapter presents the protocols generally implemented in the literature in order to define the batches of specimens to be tested in the case of the powder bed fusion and laser metal deposition processes.
