This is 650-square-foot cement house that was built by a 3D printer. In less than 24 hours. For around only $10k. And ICON, the construction tech firm behind the Vulcan 3D printer that made it happen, says even that cost will eventually come down to around $4k, with build time for complete 400- to 800-square-foot homes possible in 12 to 24 hours.
