# Print Your Home (DD-440)

> Construction 3D printing uses large gantry or robotic-arm printers to extrude concrete or similar mixes layer by layer, building walls directly from a digital design. Printing the walls of a small house can take roughly 24 to 48 hours of print time, though roofs, windows, plumbing and finishing add more time. Supporters cite less labor and waste. The footage shows a printer laying concrete walls.

### Transcript

3D printing homes is a revolutionary construction method where large scale 3D printers build houses layer by layer using materials like concrete or composites. This technique significantly reduces construction time, [...] entire homes can be printed in as little as 24-48 hours, while minimizing labor costs and material waste. 3D printing has the potential to transform the construction industry. NOW YOU KNOW!
