The wide-use of advanced ceramic-based materials depends on the availability of industrial processing routes to fabricate parts with required geometries. Owing to the inability of current technology related methods to produce complex-shaped ceramic parts with the desired microstructures and properties, Additive Manufacturing (AM) is becoming increasingly important approach. The mechanical properties of the materials fabricated by AM techniques in many cases are similar to the corresponding properties for commercially available ceramic-based materials fabricated by other methods. AM technologies can create parts using advanced materials superior to traditional ones. Layer-wise fabrication of the parts by AM techniques, however, can lead to unsatisfactory surface roughness. In order to improve the surface finish different methods have been studied. Dense ceramic-based composites with complex geometry have been fabricated via different AM processing routes. Microstructure and mechanical properties of the fabricated composites have been investigated.
