Development of metal selective laser melting (3D printing) technology for microgravity environment with colloid-like feedstock

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.
