Here is an account of the Mars habitat printing contest held last week in Illinois between teams from Penn State and the New York-based design agency AI SpaceFactory in the final phase of NASA’s 3D-Printed Habitat Challenge competition: AI SpaceFactory Wins NASA’s 3D-Printed Extraterrestrial Habitats Challenge – IEEE Spectrum –
In a cavernous arena outside of Peoria, Illinois, two industrial robots worked against the clock last weekend to finish their tasks. Each had been converted into a towering 3-D printer and programmed to build one-third-scale models of extraterrestrial habitats. For 30 hours over three days, generators chugged and hydraulics hissed as robotic arms moved in patterns, stacking long beads of thick “ink” into layers. Gradually, familiar forms began to emerge from the facility’s dirt floor: a gray, igloo-like dwelling and a tall, maroon egg.
Humanity’s future on Mars was taking shape.
AI SpaceFactory took first place and $500k while the Penn State team came in second and got $200k.

A release from NASA on the awards
After 30 hours of 3D printing over four days of head-to-head competition, NASA and partner Bradley University of Peoria, Illinois, have awarded $700,000 to two teams in the final round of the 3D-Printed Habitat Challenge. The top prize of $500,000 was awarded to New York based AI. SpaceFactory. Second-place and $200,000 was awarded to Pennsylvania State University of University Park.
The two teams faced off May 1-4 at Caterpillar’s Edwards Demonstration & Learning Center in Edwards, Illinois, creating subscale shelters out of recyclables and materials that could be found on deep-space destinations, like the Moon and Mars. The size of the structures had to be a one-third scale version of their architectural designs. Each team employed robotic construction techniques that allowed minimal human intervention. Such technologies will enable more sustainable and autonomous exploration missions.
“The final milestone of this competition is a culmination of extremely hard work by bright, inventive minds who are helping us advance the technologies we need for a sustainable human presence on the Moon, and then on Mars,” said Monsi Roman, program manager for NASA’s Centennial Challenges. “We celebrate their vision, dedication and innovation in developing concepts that will not only further NASA’s deep-space goals, but also provide viable housing solutions right here on Earth.”
The habitats were constructed in 10-hour increments in front of a panel of judges. Once printing was complete, the structures were subjected to several tests and evaluated for material mix, leakage, durability and strength.
Beginning in 2015, the multi-year, multi-phase competition challenged teams to demonstrate many different additive manufacturing technologies, from design to software modeling to physical construction. The unique challenge was competed in three phases: design, structural member and on-site habitat construction. The challenge structure allowed NASA to task the teams to address many facets of 3D construction, and to involve a broader range of teams with various expertise. Throughout the competition, more than 60 teams have participated, and NASA awarded over $2 million in prize money.
“It is an impressive achievement for these two teams to demonstrate this disruptive and terrific 3D-printing technology at such a large scale,” said Lex Akers, dean of Bradley’s Caterpillar College of Engineering and Technology. “By teaming up with NASA and Caterpillar, we are proud to bring these teams together in an environment where they can innovate, create and challenge our vision of what’s possible. Congratulations to both teams for their accomplishments.”
The 3D-Printed Habitat Challenge is managed through a partnership with NASA’s Centennial Challenges program and Bradley University in Peoria, Illinois. Bradley has partnered with sponsors Caterpillar, Bechtel, Brick & Mortar Ventures and the U.S. Army Corps of Engineers to administer the competition. NASA’s Centennial Challenges program is part of the agency’s Space Technology Mission Directorate, and is managed at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
