As such, the primary objectives for this project were: (1) synthesis of mayenite electride feedstock for additive manufacturing, (2) development of a binder jet additive manufacturing (BJAM) platform for ceramic materials, and (3) exploration of improvements to BJAM to enable high-density ceramic components. To achieve these objectives, the approach was to pursue six major milestones: (1) synthesis and characterization of mayenite and mayenite electride ceramics, (2) fabrication of a powder spreading testbed, (3) exploration of powder feedstock and powder spreading parameters on powder bed layer density, (4) fabrication of a binder jet additive manufacturing testbed, (5) development of custom binder synthesis process for BJAM, and (6) exploration of reactive binder jet additive manufacturing for densification control of ceramics. A summary of each milestone, including accomplishments, contributions to state of the art, and transitions are provided below.
