3D-Printed Houses

How Does this Technology Work?

A 3D-Printed house works when a robotic arm lays layers of concrete over the foundation and the rebar after they are placed. The concrete is layered like frosting with hollow parts for wiring and plumbing to go through once the construction is done. The robot layers the concrete horizontally until said wall is finished, and once it is finished it moves onto the next wall automatically. (walls aren’t necessarily made of traditional concrete and may be made of another, eco-friendly, material called “green cement”). 

How is this an Improvement from Before?

Average homes of the same size can take anywhere between 6-8 months to create, but these 3D printed houses can have all their walls in 10-45 days. (which is around 5x faster) Normal production of homes can be very harmful to the environment, but with robot building by itself, and the use of non-concrete materials, CO2 emissions decrease during production. Another benefit is that since these houses can be made very fast, it is easy for companies to build many houses in a restricted period of time. This can help the housing shortage, allowing more houses for more people in a timely manner.
