After 150 years of concrete construction development, 3D concrete printing now makes it possible to use the material precisely and, above all, economically. For the first time, filigree concrete elements can be produced quickly and without costly formwork construction. Lightweight ceilings made with the highly innovative digital process need 35 % less material than conventional in-situ concrete ceilings, which are usually the same thickness at all points. Now optimised concrete structures are printed as lost formwork and, where statically required, in-situ concrete is added. The scientific groundwork was carried out from 2015 to 2019 in the research project COEBRO – Additive Fabrication of Concrete Elements by Robots. The process is now being gradually further developed. If we consider the millions of ceiling elements concreted every year, this shows the enormous potential of the technology for saving resources and for a paradigm shift in concrete construction.

Timeular – the remote company, seit 2016
Timeular is a remote work company, meaning that its employees are not tied to a physical office and are in fact spread across four continents and nine countries.
Deep Learning für MRT Rekonstruktion, from 2018
In recent years, the ‘Vision, Learning and Optimization’ research group led by Thomas Pock at Graz University of Technology has developed ‘variational networks’ (VNs), which combine the advan-tages of traditional mathematical variational methods with deep learning methods.
