The most modern way to build houses is to print them. Whereas in traditional construction, shapes that deviate from the cuboid of the building blocks used are built using complex and expensive moulds for concrete casting, with 3D printing these can be realized at no extra cost. Topo is a design, analysis and manufacturing process for additively manufactured solid building blocks. The architect is given complete freedom in designing the shape of each individual brick. This enables the simple, cost-effective and material-saving realization of individual building façades.
