In other words, 3D-printed real estate is taking off in a big way. That first home that went up for sale hasn't even been built yet. The company, SQ4D, printed a model home at a concrete yard on Long Island, New York, and hosted more than a hundred showings. The new home will be printed on a lot nearby. ICON, a pioneer in 3D-printed homes in the U.S., just completed four homes in East Austin, Texas. In partnership with Kansas City-based developer 3Strands, the two- to four-bedroom homes are now on the market, starting in the $400,000 range. "The demand has been off the charts, hard to manage even," said Gary O'Dell, co-founder and CEO of 3Strands. "The feedback could not have been more positive."
