Abstract Scope |
Direct Ink-Writing is an extrusion-based additive manufacturing technique in which viscoelastic inks such as resins, gels, or pastes are deposited onto a translation stage in a pre-defined sequence. Commonly, these materials consist of two or more components that are mixed during the printing process and cured upon deposition1. Careful selection of the curing method, material components, and process parameters allow for fabrication of a wide range of materials with functionalized additives and fillers. Multiple methods of in-situ curing have been developed to address one of the primary challenges of Direct Ink Writing: optimizing the mechanical properties of the material post-extrusion2. Significant investment into the development of this technology for the nuclear enterprise has been made by the NNSA thus far; with mirrored capabilities being implemented at LANL, LLNL, and KCNSC with the intention of increasing the production yields of current weapons components and evaluating the efficacy of new materials for legacy and future systems. Our work presented here aims to provide an overview of the Aerotech 5-axis Direct Ink-Write printer; highlighting its benefits, challenges, and potential as a manufacturing capability at Los Alamos National Laboratory. |
