Most homes are built block by block or brick by brick. However, a demo house in Calverton, New York, US, was constructed scan by scan with walls made using a giant 3D printer.

The house is 180 square meters with a total print time of 48 hours. After the concrete was set up and dry enough, the truss roof system was installed, and then, the interior was finished.

The company is building a near-identical home which is on the market for 299,000 dollars, and the feedback that they get is both positive and negative. According to the company’s director, people are simply unprepared for how construction of homes is going to change. Younger people know 3D printing and it’s a great thing for them. However, some older tradesmen and gentlemen in the field don’t know what 3D printing is and how a house can be made on a 3D printer.

3D printing is a viable way to build because concrete is used which is abundant and used every day all over the world.

Difficult words: demo (something that is made to show how something works or how it is done), truss (a framework that supports a roof, bridge, or other structure), viable (capable of existing), abundant (something that exists in large amounts).
