Ever since I first saw a 3D printer I wondered how long it’d be before they’d start scaling up in size. Now I’m not talking about incremental size improvements that we see every so often (like with the new Makerbot Z18), no I was wondering when we’d get industrial scale 3D printers that could construct large structures. The steps between your run of the mill desktop 3D printer and something of that magnitude isn’t a simple matter of scaling up the various components as many of the assumptions made at that size simply don’t apply when you get into large scale construction. It seems that day has finally come as Suzhou Yingchuang Science and Trade Development Co has developed a 3D printer capable of creating full size houses:
Details the makeup of the material used, as well as its structural properties, aren’t currently forthcoming however the company behind them claims that it’s about 5 times as hard as traditional building materials. They’re apparently using a few of these 3D printed buildings as offices for some of their employees so you’d figure they’re somewhat habitable although I’m sure they’re in a much more finished state than the ones shown above. Still for a first generation product they seem pretty good and if the company’s claims hold up then they’d become an attractive way to provide low cost housing to a lot of people.
What I’d really be interested to see is how the cost and materials used compares to that of traditional construction. It’s a well known fact that building new housing is an incredibly inefficient process with a lot of materials wasted in during construction. Methods like this provide a great opportunity to reduce the amount of waste generated as there’s no excess material left over once construction has completed. Further refinement of the process could also ensure that post-construction work, like cabling and wiring, are also done in a much more efficient manner.
I’m interested to see how inventive they can get with this as there’s potentially a world of new housing designs out there to exploited using this new method. That will likely be a long time coming however as not everyone will have access to one of these things to fiddle around with but I’m sure just the possibility of a printer of this magnitude has a few people thinking about it already.
