3D-Printing Bricks From Discarded Eggshells

Mexican multidisciplinary design studio MANUFACTURA devised a new way to create building materials from discarded eggshells. The team used locally-sourced food waste (collected from donations and nearby restaurants) that, when combined with bio-binders, became a thick material compatible with 3D printers. The eco-friendly method then merged digital manufacturing and computational design to create an eggshell brick, from which a wall can be formed (composed of 105 different blocks) or a column (from 26 pieces). The initiative, dubbed the Eggshell Project, tackles not only the unsustainable methods of the construction industry, but also excessive food waste in Mexico.
