The Bundesanstalt für Materialforschung und -prüfung (BAM) presented its research on additive manufacturing methods for complex concrete components at the Hannover Messe 2019. These methods could be used to produce tailor-made components for sewage systems quickly and economically in the future.
Traditionally, concrete component manufacturing is arduous and design possibilities are limited by the formwork. Should infrastructural elements require replacement due to damage, this repair work is often costly. Additive manufacturing opens up new possibilities to manufacture customized products or even small batches of concrete components in an efficient manner. Together with Clausthal University of Technology, BAM is working on laser-based additive manufacturing of alkali-activated concrete. Not only does this have a higher chemical resistance, but in combination with 3D printing technology, it could also provide unique possibilities for industrial applications. "Additive manufacturing is already being utilized for plastics and metals with great success," explains Prof. Dr Jens Günster, project leader and head of the Ceramic Processing and Biomaterials division at BAM. "We want to further develop the manufacturing process so that it can also be safely applied in the construction materials sector."
