Abstract
- In this work we demonstrate the feasibility of fabricating textured alumina employing a lithography-based ceramic manufacturing process. The combination of vat rotation and platform immersion contributes to the alignment of alumina templates during printing. Templated Grain Growth during sintering provides a high degree of texture (Lotgering Factor ~ 0.80) with relatively low porosity (approx. 7%). A comparable characteristic biaxial strength of 640 MPa and 570 MPa was measured for textured and equiaxed alumina samples, opening the path for 3D printing textured ceramics of complex architectures for structural and functional applications.
