dc.description.abstractBinder Jetting Additive Manufacturing is renowned for its high powder reusability ratio, reaching near 100 % for certain alloys. This technology offers an advantage over thermal-based methods, such as laser or electron beams, which can degrade or sinter the surrounding powder particles, diminishing the reusability ratio. However, during the setup and production of parts, defects may occur, leading to the direct rejection of certain printed components. The objective of this work is to investigate the feasibility and impact of reusing powder from rejected parts, aiming to achieve zero waste and maximize the utilization of metallic powders. To accomplish this, the rejected parts underwent a series of processes including debinding, sieving, characterization, and subsequent mixing with virgin powder at various proportions. The goal was to identify suitable mixing ranges that would enable the production of high-quality material. The study focused specifically on the 17-4PH alloy and confirmed that employing separate debinding and sintering processes facilitates the complete recirculation of all used powder, thus achieving zero waste. This finding highlights the potential for implementing a closed-loop system that maximizes powder reusability and minimizes material waste in the Binder Jetting Additive Manufacturing process.en
