Abstract Scope |
3D printing is a promising technique to develop nuclear fuel with complex geometry without the need for post-processing such as drilling or machining. A key issue with many current 3D printing techniques is their relatively low green body densities. This study utilizes a novel technique using sparking plasma sintering (SPS) to highly densify 3D printed green body ceramic particles suspended in a polymer binding. Cylindrical samples with no holes were densified as well as cylindrical samples with 7 channels while maintaining geometry. An important aspect of this densification is the mechanical strength of the green body parts to ensure geometry is maintained throughout sintering. This work advances techniques which can be used to design nuclear fuels using surrogate materials, and allows for both ceramic composites, as well as one-component ceramics. |
