This looks to be where the technology will remain for the time being: temporary novelty structures for exhibitions and events. So far, only a small pavilion-sized structure has been printed. Another Dutch architect, Janjaap Ruijssenaars, is working on a project to print a house shaped like a looping Mobius strip with the Italian-made D-Shape printer, which uses sand mixed with a binding agent to create a form of synthetic sandstone. Since 2008, researchers at the University of Southern California have been developing a technology, known as contour crafting, that uses a computer-controlled gantry to print structures in quick-setting concrete, which they say is potentially capable of printing high-rise buildings, with the printer climbing the structure as it grows. While Dus may be the first architects to start printing a full-scale house, they join a number of others who have been experimenting with printing at an architectural scale over the last few years.

They have also produced tests with a translucent plastic and a wood fibre mix, like a liquid form of MDF that can later be sawn and sanded. The current material is a bio-plastic mix, usually used as an industrial adhesive, containing 75% plant oil and reinforced with microfibres. “We're still perfecting the technology,” says Heinsman. There are lumps and bumps, knots and wiggles, seams where the print head appears to have paused or slipped, spurting out more black goo than expected. In places, it looks like bunches of black spaghetti. It uses the same principle of extruding layers of molten plastic, only enlarged about 10 times, from printing desktop trinkets to chunks of buildings up to 2x2x3.5m high.įor a machine-made material, the samples have an intriguingly hand-made finish. At the centre of the process is the KamerMaker, or Room Builder, a scaled-up version of an open-source home 3D-printer, developed with Dutch firm Ultimaker. ![]()
