3D Printed Houses – Technology Making Affordable Housing
At home late one night, an energy drink in one hand, the 3Doodler pen in the other, Platt Boyd had his breakthrough. Like hot glue from a gun, the molten plastic secreted by the 3Doodler hardens as it cools, which allows the user to draw 3D shapes. Eventually the tiny 3D object he had created minutes before was holding up 18 pounds of books.
Now 3D printing is making its way into single-family home construction. Eric Schmidt, executive chairman of Google’s parent company, Alphabet, named 3D-printed construction one of the next moon shots at last year’s Milken Global Conference. Instead of powdered metals and plastic, mixtures of cement, sand, and plastic-polymers are the building materials. Instead of stationary, box-like machines, large robotic arms on a swivel produce fully functional houses, with electricity, plumbing, roofs, and windows.
Pioneers of 3D-printed construction rattle off what they see as numerous advantages: decreased costs and the consequent ability to follow through on their inventive architectural plans, as well as simpler and sturdier houses built more quickly. The price is lower for home buyers, too. The house Apis Cor built last December cost just over $10,000. By comparison, a three-bedroom, 1,050-square-foot house built by Habitat for Humanity costs roughly $50,000.How to print a house – Curbed
