The project that I picked is 3D-printed houses that are being fabricated by SQ4d. This project is being carried out in different locations in New York and is printing sustainable and affordable housing. They are using a 3D printer made out of aircraft-grade aluminum and have the capability to print any material, right now specifically printing mortars and concrete.
This company has been printing houses since it was founded in 2017. The director of operations is Kirk Andersen and his goal is to speed up the production of homes while lowering the cost overall and the environmental impact. The company is a collection of engineers, designers, architects, and tech specialists which work in an interdisciplinary manner to engineer and produce these projects. I have linked a podcast from Kirk Andersen, the SQ4D website, and a news article about the company.
