3D PRINTING OF CONCRETE

SINTEF & Partners

HINDCON, “Hybrid INDustrial CONstrucion”, is an EU-funded project, studying 3D-printing of concrete in the construction sector. The project aims to develop a 3D printing “all-in-one” machine for large scale advanced manufacturing and building processes, advancing towards industrialisation and overcoming the limitations of the current approach for introducing 3D-printing in construction activities.

SINTEF’s role in the project is to research how the new 3D-printing construction will affect the construction process, in terms of lean manufacturing but also how the new processes affect the construction workers.

Advanced Manufacturing has been highlighted by the EU as one of the key enablers to support and promotion of business research and innovation in key enabling technologies. Therefore, a number of objectives, aligned with pursuing the large scale targets, have been set for advanced manufacturing through four pillars: technology, economic, social and environment.

The main aim of the HINDCON project is to develop and demonstrate a hybrid machine regarding 3D printing technologies with concrete materials focused on the industrialization of the Construction Industry, delivering to this sector an innovative technology that reduces environmental impact at the same time it reduces dramatically economic costs. The collaborative structure of the project will help to:

  • Integrate different technologies that converge in a hybrid solution. HINDCON “all-in-one” machine will integrate Additive Manufacturing concrete extruder and Subtractive Manufacturing tool kit with the use of cementitious materials including mass materials with alternatives in concrete and additives, and reinforced with composites.
  • Cover the different aspects concerned (technology, economic, social and environment) and demonstrate the hybrid machine from different perspectives. On the one hand, it includes testing basic capabilities of the integrated prototype in laboratory. On the other hand, it involves the demonstration of the manufacturing system in a relevant environment.

HINDCON is funded under the H2020-EU program: Technologies for Factories of the Future, and is co-ordinated by Vias y Construcciones in Spain.
