In the course of this project, authors have developed an additive manufacturing technique firmly rooted in the Powder Bed Fusion methodology, specifically designed to address the challenge of Off-Earth Manufacturing. The unique aspect of the technology lies in the utilization of a specialized feedstock material in form of a colloidal mixture. This material has the remarkable capability to create a rigid and stable powder bed, making it exceptionally well-suited for operation in zero-gravity conditions. While this novel technique certainly comes with its own set of challenges, the project's outcomes demonstrate its capacity to successfully fuse titanium alloy powder in layer-by-layer manner. Furthermore, the specific feeding mechanism designed for this unique feedstock enables consistent and stable powder deposition, showcasing its feasibility for practical applications in zero-G conditions.
