Representing Joris Laarman’s exploration of 3D-printed furniture, the Microstructures, aluminium gradient chair is printed in aluminium using a computer algorithm which modifies the material’s printed cellular structure, thickness, density and pattern according to the structural requirements of the chair. Similar to the actions of bones and plants, at times when strength is required the cells that make up the chair tighten to become solid metal, and at other times open up to reduce the chair’s weight. Using geometry in this way allows Laarman to harness the technology of 3D printing to optimise the structures of objects according to their function.
