Additive manufacturing is becoming increasingly popular for the fabrication of complex metallic components. However, many of the forming processes result in unused material of an unknown quality for recycling in future use. Material properties, surface properties, and particle geometric characteristics of recycled powders are important considerations in determining whether powders can be reused. In this study, we examine the particle size and shape distribution development of recycled powder product through successive build/recycle cycles. The particle size and shape distribution is evaluated using computed tomography X-ray (CT) scanning and conventional scanning electron microscopy techniques. Finally, components manufactured during each cycle are evaluated to determine whether their mechanical properties change over successive cycles given a fixed set of processing conditions. Testing and evaluation is performed on two metals with different oxidation propensity to evaluate the effect of particle surface changes on mechanical properties.
