China is quick at absorbing new technology trends to produce their own solutions. HuaShang Tengda is a Chinese construction company that literately 3D prints entire houses. No, it does no print it in parts; the printer works on site to build the house as a whole. The result is a full sized two-story 400 square feet house that can withstand an earthquake of 8.0 on the Richter Scale.
How do they do it?
3Dprint.com explains the process: a team first creates a frame of the house along plumbing pipes, and a printer systematically “prints” layer-by-layer with regular Class C30 concrete cement. The printer is controlled by a 4 stage computer-controlled system that mixes ingredients, transmits the cement and 3D prints the house. HuaShang Tengda took months to develop the printer, considering its size and capacity.
This isn’t the first 3D-printed house by any means, however, 3D-printed houses before this were built by printing and assembling parts, and not by literally printing it on-site. The use of inexpensive concrete, automation, and minimum human intervention makes 3D-prinitng houses extremely affordable. It is also safer and more environment friendly because heavy machinery isn’t used, and eco-finely concrete is used.
HuaShang Tengda envisions to use this technology in all areas - from farmlands to dense city centres - for easy, affordable construction. This will, perhaps, revolutionize the construction industry in China, and eventually the world.
