A Dutch architect unveiled a unique 3D printer with which he aims to construct a large building “without beginning or end” shaped like an infinite loop. It is just like a normal printer, architect Janjaap Ruijssenaars of Universe Architecture in Amsterdam, said as he presented the tool. Instead of putting ink onto paper, you are putting a liquid onto sand, which solidifies wherever the liquid has been spread, he said. Ruijssenaars aims to print the Mobius strip-shaped building with around 1,100 square metres of floor space using the massive D-Shape printer. Designed by Italian Enrico Dini, the printer can print up to almost a six-metre-by-six-metre square using a computer to help build up fine layers of 5-10 mm thick. The machine is almost two metres long and has been set up in a warehouse in Amsterdam, where the final tests are being carried out before pressing ahead with the start of building. The ambitious project was first unveiled in 2013, and the team has been in touch with various partners hoping to be able to start construction within the next few years. It is hoped the building, which will also include more traditional design elements, can be used as a space for exhibitions or sculptures.
