| Abstract Scope |
This study investigates the rheological, chemical, and mechanical properties of Black Hills-sourced Fuson Shale for use in ceramic additive manufacturing (AM). The local clay was processed and evaluated alongside a commercial stoneware clay. Shear and compressional rheology tests characterized viscoelastic behavior relevant to extrusion. Both clays were 3D printed and sintered at 998°C, 1222°C, and 1285°C. X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses identified phase changes, vitrification, and densification patterns. Mechanical performance was measured using ASTM C1161 3-point bend testing. Fuson Shale achieved higher flexural strength than the commercial clay, with a peak median value of 36 MPa at 1222°C. Results demonstrate the viability of local clays in ceramic AM and support future use in remote or off-Earth manufacturing applications. |
