NASA, www.nasa.gov. Washington, D.C., and the National Additive Manufacturing Innovation Institute, known as America Makes, www.americamakes.us, Youngstown, Ohio, are sponsoring a $2.25 million competition to design and build a 3D printed habitat for deep-space exploration, including the agency’s journey to Mars.

The multi-phase 3D Printed Habitat Challenge, part of NASA’s Centennial Challenges program, is designed to advance the additive construction technology needed to create sustainable housing solutions for Earth and beyond.

Shelter is among the most basic and crucial human needs, but packing enough materials and equipment to build a habitat on a distant planet would take up valuable cargo space that could be used for other life-sustaining provisions. The ability to manufacture a habitat using indigenous materials, combined with material that would otherwise be waste from the spacecraft, would be invaluable.

The first phase of the competition runs through September 27. This phase, a design competition, calls on participants to develop state-of-the-art architectural concepts that take advantage of the unique capabilities 3D printing offers.

The second phase of the competition is divided into two levels. The Structural Member Competition (Level 1) focuses on the fabrication technologies needed to manufacture structural components from a combination of indigenous materials and recyclables, or indigenous materials alone. The On-Site Habitat Competition (Level 2) challenges competitors to fabricate full-scale habitats using indigenous materials or indigenous materials combined with recyclables.

Winning concepts and products will help NASA build the technical expertise to send habitat-manufacturing machines to distant destinations, such as Mars, to build shelters for the human explorers who follow. On Earth, these capabilities may be used one day to construct affordable housing in remote locations with limited access to conventional building materials.
