Models made out of ceramics are constructed from alumina silica ceramic powder and sealed with porcelain and silica. The glaze that is applied after printing is a lead free, non-toxic gloss. The material is heat resistant (up to 600°C), recyclable, and currently the only food safe 3D printing material. All of this makes it the perfect material for home decor stuff and table ware, especially when food and beverages get involved.
