Losing the edge

Losing the edge is a series of stackable 3D printed object realized in geopolymer.

Geopolymers are inorganic solid materials that are formed by the chemical reaction of a powder rich in silicon oxide and aluminium oxide with a liquid alkaline activator. When properly mixed with other materials, such as clay or bentonite, they form a viscous fluid that can be 3D printed with LDM printing technique.

The geopolymer reacts at room temperature, without requiring a heat treatment as  clays do. The final material is a solid with properties similar to the concrete ones but with a higher resistance to heat and flames. Furthermore, they have a less severe environmental impact than cement paste and it is possible to substitute some of the starting reagents with materials coming from industrial wastes or renewable resources.
