Revolutionizing the way we build via digital fabrication technologies

During the 2017 World Economic Forum, ETH Zurich showcased its latest innovations in Game Technology and robotics. The National Centre of Competence in Research (NCCR) Digital Fabrication was represented by Prof. Benjamin Dillenburger who explained why digital fabrication can be a game changer for the building industry.

Why should we bring 3D printing technologies to architecture and construction? This was the question we addressed during the IDEAS LAB on “Engineering for Creativity” by ETH Zurich at the WEF in Davos.

Upscaling 3D printing technology for construction

So far, architects have used 3D printing technology mostly for making prototypes. Dillenburger and his team are now working on the upscaling of 3D printing for architectural applications:

“In our research, we are trying to scale up printing processes and to bring them to construction sites. We are working with one of the biggest 3D printers of the world. This is a printer that can print 4 x 2 x 1 meters in 36 hours”.

The WEF 2017 audience was shown the 4.2 Terabyte print space Dillenburger and his team are currently working with. But what is the actual benefit which 3D printing will bring to architecture?

“One thing is that we are facing more and more complexity in building elements. Architecture is an overlay of multiple systems that all have to be compressed. And we hope to integrate all these different systems in 3D printed components together. Another important aspect is reducing material. To have material only where it is actually needed”, highlighted Dillenburger.

At the moment, Dillenburger and his team are working on a ceiling for an actual building project: the Unit Digital Fabrication on the NEST building of Empa in Dübendorf. The prefabricated ceiling will be a combination of 3D sand-printing and reinforced concrete and will not only be significantly lighter than conventional concrete ceilings, but also integrate thermal activation and acoustic performance.

WEF provided a great opportunity for the NCCR Digital Fabrication to present its cutting-edge research to academic and economic leaders from around the world, and the NCCR is looking forward to similar occasions.
