The Bundesanstalt für Materialforschung und -prüfung (BAM) will present 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. Prototypes of various 3D-printed components will be on display for those attending the trade fair.
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 customised products or even small batches of concrete components in an efficient manner. This is where BAM’s research steps in. 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 utilised 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."
BAM is also involved with the AMITIE EU project (Additive Manufacturing Initiative for Transnational Innovation in Europe). Within the scope of AMITIE, BAM scientists are cooperating with Desamanera, an Italian start-up. Together, they want to optimise 3D printing for very large, complex concrete and mortar components.
Where to find BAM at the Hannover Messe 2019
The main theme of BAM’s exhibition this year is additive manufacturing. Under the slogan "We add Safety to Additive Manufacturing" visitors will be able to gain insight into BAM's research in this area. BAM is also presenting its commitment to promoting spin-offs (stand C51 in the Research & Technology area in hall 2).
BAM will provide information on the quality assurance of offshore wind turbines in the same hall at the BMWi trade fair stand (hall 2, stand C28).
The publication "Additive Manufacturing at BAM - Safety in Focus" provides an overview of the wide range of our research in this area: www.bam.de/am-broschuere
