Icon is a company that seamlessly constructs buildings onsite without having to piece together individual units.
The company's 3D printer, known as the Vulcan, will churn out layers of cement to simulate a realistic Mars. The habitat intends to inform and support crew health and performance for future missions.
3D-printed homes are becoming increasingly popular. They are quick to build, and in some cases, it takes just a few hours to print a home.
In 2019, Icon partnered with New Story, a housing nonprofit based in San Francisco to produce a 350-square-foot tiny home that took just 48 hours to build.
