A substitute for ivory has been engineered by researchers at Austria's Technical University of Wien (TU Wien) and three-dimensional (3D) printing spinoff Cubicure, in cooperation with the Archdiocese of Vienna's Department for the Care of Art and Monuments and Addison Restoration.

The substance called "Digory" combines synthetic resin and calcium phosphate particles, processed in a hot, liquid state and cured layer by layer in a 3D printer with ultraviolet light.

After printing, the object can be polished and color-matched to give the material an authentic ivory appearance.

Cubicure's Konstanze Seidler said, "It is further proof of how diverse the possible applications of stereolithography are."
