Interest in Zircaloy-4 scrap recycling has increased in recent years. Zircaloy-4’s high melting temperature and powder reactivitypose significant challenges for metal additive manufacturing (MAM). In this study, Zircaloy-4 parts were built usinglaser powder bed fusion MAM for the first time. The reactivity of the Zircaloy-4 powder was successfully suppressed duringthe entire manufacturing process. The mechanical properties of the printed Zircaloy-4 were evaluated at room temperatureand reactor operating temperature of 316 °C. Remarkable yield strengths at both temperatures were obtained. This studywill serve as a starting point for safe Zircaloy-4 additive manufacturing.
