Providing housing for low-income and disabled residents is Habitat for Humanity’s mission. But, to do that faster and lower cost, it gets the help of 3D printing technology. They build 3D-printed homes in just 12 hours.
Habitat for Humanity is an international nonprofit company. It is partnering with a list of advanced home construction to speed up printing exterior walls with liquid concrete.
The process, in old methods, would take nearly four weeks to construct. However, by using 3D printing, it only took 12 hours to finish building the house. The new house, which the company built in Virginia for a mother and son, is 1,200-square-foot with three bedrooms and two baths.

The company, by using an Alquist 3D printer, provided the house with a concrete structure, which can resist hurricanes and tornadoes. Also, it comes with its own personal 3D printer that will print anything from cabinet knobs to electrical outlets. In addition, to a proprietary Raspberry Pi-based monitoring system.
This system is a smart home program that allows the owners to manage nearly everything. Like, security, indoor environments, space utilization, security, emergency protocols, comfort, and energy efficiency.
Using Alquist’s concrete method will save approximately 15% per square foot if we compare it with preliminary lumber estimates.
The families which the Habitat for Humanity program accepted will put in hundreds of hours of work to build their homes.
Hopefully, in the near future, this 3D printing technology will be a way to procure more affordable homes for low and moderate-income families.
