Ceramic dental crowns have a low risk of metallic allergies and are esthetically pleasing and so are actively investigated and developed in worldwide medical industries. In this study, three-dimensional dental-crown models composed of alumina and glass composite were fabricated successfully by using stereolithography. These precursors were dewaxed and sintered in air. Alumina bending test specimens of 1.2×4×20 mm in dimensions were fabricated by using the similar materials and processes. The highest bending strength of alumina ceramics with La₂O₃-B₂O₃-Al₂O₃-SiO₂ glasses was about 400 MPa. These glass components were coated on the alumina specimens to close micro cracks on the surface
