Building a house is quite the production. There’s the time, the expense, the dust, and the leftover building materials that hang around in the garden for years after the builders clear off.
Unless, that is, you print it. From its home in a Dutch shipping container, a giant 3D printer, the KamerMaker (“room builder”), is currently spurting out globs of molten bioplastic to form walls. The honeycomb-esque design leaves room for pipes and wiring to be installed later.
KamerMaker is the brainchild of Amsterdam-based DUS Architects, which is using it to build a 15m high, 6m wide house on the banks of a canal in the city. The house’s 13 rooms will be printed individually and slotted together to form each floor; the floors will then be stacked on top of each other to create the final building. The whole thing’s a bit like giant, inhabitable lego. Construction kicked off on 1 March, and the house should be finished in, er, three years’ time. You can see their rendering of the finished building above – just don’t ask us what the weird ghost buildings on either side are about.
So, if the process is still so slow, what exactly are the advantages of printing a house? For a start, there’s no waste, as the printer uses raw materials and only prints what’s needed; plastic waste from other industries can be recycled as “ink”. As long as a house can be printed near its final location, transport costs are low. And this prototype has no foundation, so that’ll cut down on costs, too. (Although a team is currently on the problem of how to stop it toppling into the canal once it’s constructed; the current plan is to fix it in place with long metal poles.) When it’s no longer needed, the building can be shredded and its materials reused.
