Months ago, I blogged about Winsun, a Chinese firm that used recycled industrial waste as ink to 3D print 10 simple structures in 1 day. Recently, it has literally built on that success,
"showing off the two neighboring projects, one an 1100-square-meter villa, the other a 6-story residential block, in the Chinese city of Suzhou. The residential block is the world’s tallest 3D-printed building, according to the company. It took Winsun a day to print out one level of the residential block, and then five more to put the level together. As for the villa, both the interior and exterior of the home were created using the company’s 3D printing tech."
And the company has no plans to stop here, arguing it can use its additive manufacturing process to print structures up to 12 stories high. Given the reduced cost and time it takes to produce its buildings, Winsun is banking on expanding into other markets, especially in third-world countries and disaster-affected locations.
One obstacle to its ambitious plans are lingering safety concerns about its ink which includes glass as an ingredient. Although Winsun argues its ink is safe, some experts have concerns that it may not be suitable for long-term dwellings.
