We have seen 3D printing via robotic arm before. The 3D printing material is a type of mineral foam made from recycled materials. The design required 12 different shapes and 24 individual elements. The foam parts can be left in or removed at the end of the process. The resulting structure is strong but lighter than a conventional concrete structure. The foam elements go in a conventional wood form and are cast as usual with - in this case - high-performance fiber-reinforced concrete. Using a robotic-arm 3D print technique, the researchers can lay out prefabricated blocks of foam that create forms with highly complex shapes. However, if you can create complex shapes you can easily put material where it adds strength and omit material where it doesn’t carry load. That’s easy to do, but hard to make complex shapes. Typical concrete work relies on a form often made with wood, steel, or plastic. You can see a video about the process, below. It also offers improved insulation properties. That’s according to a team at ETH Zurich who claims that construction with foam forms cuts concrete usage up to 70%. The latest 3D printing application? Forming concrete.
