Ivory, a hard, white material consisting mainly of dentine, makes up the tusks of several large animals, such as walruses, narwhals, and elephants. For a long time, the material was highly sought after for use in making artwork, but thankfully the ivory trade was banned internationally in 1989 to protect decreasing elephant populations. However, a lot of this intricate artwork, as well as ivory artifacts, is obviously still out there, and alternate materials, such as bones, plastic, and shells, are used to restore them, with middling results. But a partnership between the Vienna University of Technology (TU Wien) and Cubicure GmbH, the university’s spinoff company, has resulted in a 3D printable, elephant-friendly substitute for ivory that can be used to restore these pieces with high precision.
Through a cooperation with the Archdiocese of Vienna‘s Department for the Care of Art and Monuments and Vienna-based Addison Restoration KG, Cubicure and TU Wien have created Digory, a novel material made of calcium phosphate particles, silicon oxide powder, and synthetic resin. First processed in a hot, liquid state, Digory is hardened into the desired shape using UV rays, and once it’s off the printer, it can be polished and color-matched to a specific
