Process and building material technology consulting, support during planning and execution, building inspectorate approvals. (lecture only accessible in German)

3D printing or additive manufacturing is a new construction technology that makes it possible to manufacture components or structures (made of concrete) in a layered construction process. In addition to the high degree of automation, this construction method is characterized by the fact that no formwork is required and a greater freedom of form and design is possible than with conventional construction methods. However, there are usually no technical construction regulations and no recognized rules of technology for the construction product, the construction method and the types of construction produced.

Therefore, we offer the following services, among others:

General advice on process technology (e.g. selection of a suitable pressure process from the depositing and particle bed-based techniques)
Concrete / material technology consulting (e.g. selection / development of suitable concretes for 3D printing)
Planning and preparation of test concepts to determine characteristic material and component properties
Advice on planning and execution (e.g. design proposals according to the partly direction-dependent material properties of 3D-printed components, support during execution)
Expert advice and support for building authority approvals as well as development of the corresponding concepts.
Prof. Dr.-Ing. Prof. h.c. Christoph Gehlen (54) is a materials scientist and professor of materials and materials testing in construction at the Technical University of Munich (TUM). His book on the design of the service life of reinforced concrete structures is considered a standard work. Together with his team, he was responsible for consulting, expert opinions and construction supervision of the two houses built so far in Germany using 3D concrete printing. Gehlen is dean of the engineering faculty Bau Geo Umwelt as well as visiting professor in Beijing (China).
