Unipor prints custom-shaped bricks

German brick manufacturer Unipor is working on the product range of the future: 3D printing technology should allow the production of custom shapes at significantly lower costs than before. The technical basis for this is a robot developed specifically for the purpose.

Working with the Technical University of Darmstadt, Unipor wants to take the benefits of 3D printing and bring them to brickmaking . The first results of the collaboration will be presented by the company during the BAU trade fair in Munich from January 14 to 19, 2019. The main focus will be on cost-effectively manufacturing custom shapes, which is not possible with conventional mass production. Examples given by the Unipor Group include custom shapes that make it easier to fit windows or attach facades to masonry.

The core of the brick printer is a special robot that processes the raw material based on a precise digital image. Additive manufacturing not only allows the construction of completely new geometric structures that are not feasible with conventional methods, but also ensures optimized use of materials and improves the physical properties of the brick. At the Technische Universität Darmstadt, the project is part of larger research plans. Researchers here are working on the use of additive manufacturing in combination with a wide range of different materials to open up new opportunities for the construction industry .
