Substitute materials are often used for restoring ivory artifacts because of the ethical implications surrounding the use of ivory. Researchers led by Vienna University of Technology and 3D printing company Cubicure GmbH developed a new material using stereolithography that they say can serve as an aesthetically and mechanically high-quality ivory substitute.

Many companies creating 3D-printed homes rely on using concrete or synthetic materials like plastic, materials not always readily available in all parts of the world. In Italy, Mario Cucinella Architects and 3D printer manufacturer WASP are collaborating to design a 3D printing process for homes that uses local soil.
