Imagine living on Mars! This fascinating idea is becoming more tangible thanks to NASA’s 3D Printed Habitat Challenge. This four-year-long competition brought together some of the world’s most talented architects and engineers to design homes for Mars. The competition reached an exciting climax when two teams showcased their designs live in front of NASA judges.
Mars has intrigued humanity for centuries. Its proximity to Earth and its potential to support life have made it a prime target for exploration. However, Mars presents a harsh environment. The planet experiences extreme temperature fluctuations, similar to a desert on Earth but far more severe, with temperatures plummeting to minus 70 degrees Celsius at night. Mars’s thin atmosphere, less than 1% of Earth’s density, offers little protection from solar and cosmic radiation. Thus, any human settlement must be designed to withstand these conditions. Importing building materials from Earth is impractical, so utilizing local resources and 3D printing technology is essential.
AI Space Factory, led by Jeffrey and his team, developed a habitat design called MARSHA. The design features a vertically printed cylindrical shape, ideal for 3D printing due to its lack of sharp corners. This shape efficiently withstands internal pressure, similar to a balloon, by reducing diameters at the ends, resulting in an egg-like form.
Choosing the right material was crucial. The team selected a polymer that could be produced on Mars, avoiding the need for water, a scarce resource on the planet. The thermoplastics used offer the advantage of reversibility; they can be reheated, remelted, and redeposited if necessary.
The team meticulously designed the habitat’s interior, optimizing each space for astronaut use. Features like a rover docking port, windows, and a skylight were incorporated. After advancing through competition levels, they reinvested their prize money into further development, culminating in a live printing event judged by NASA.
During the competition, teams had two days to set up their machines and 30 hours over three days to print a complete habitat. The process required constant supervision, with judges timing every intervention. The first day focused on the crucial foundation, followed by steady printing on the second day. On the third day, they achieved a breakthrough by printing seven feet in one day, a task that usually took two days. The final challenge was carefully placing the skylight to avoid structural issues.
After intense testing and evaluation, AI Space Factory emerged victorious. Winning felt like graduating from a four-year degree, marking a significant achievement for the team. Although the competition is over, the journey for MARSHA continues. While human missions to Mars may be decades away, the sustainable building technologies developed for space have immediate applications on Earth.
AI Space Factory is now working on TERA, a habitat for Earth inspired by MARSHA. Located in Garrison, New York, TERA will demonstrate the potential of sustainable building practices. This project highlights how space technology can address Earth’s challenges, particularly in the context of the ongoing space race and climate crisis.
In conclusion, the innovations from NASA’s 3D Printed Habitat Challenge show that exploring space and improving sustainability on Earth are not mutually exclusive goals. By applying lessons learned from space exploration, we can create a more sustainable future for our planet.

Right now, you’re looking at renderings of human settlements on Mars. These designs were part of NASA’s 3D Printed Habitat Challenge, a four-year-long competition aimed at engineering homes for another planet. The brightest architects and engineers from across the globe put their skills to the test, culminating this year in an exciting finale. Two teams went head to head to print their designs live in front of NASA judges.
Mars has captivated our imagination for hundreds of years. Its proximity to us, striking resemblance to Earth, and potential to harbor life have made it the target of many robotic missions. However, the surface of Mars is not as Earth-like as it might seem. Every day, the temperature swings significantly. It’s somewhat similar to a desert on Earth, where you have very cold nights and very hot days, but it’s much more extreme, with temperatures dropping to minus 70 degrees Celsius at night. The planet can’t retain heat because its atmosphere is very thin, less than 1% the density of Earth’s. This means we can essentially treat it like a vacuum. Combined with Mars’s lack of a magnetosphere, there’s almost no protection against dangerous solar and cosmic radiation. To survive, we need a habitat that can provide protection from this extreme environment. Since importing building materials from Earth could be prohibitively expensive, we’ll most likely have to build it there using on-site materials and 3D printing.
At architecture firm AI Space Factory, Jeffrey and his team developed MARSHA. Printing a cylinder vertically is actually the ideal shape for a 3D printer because it doesn’t have any sharp corners. It’s a gentle, predictable, and safe shape to build. The interior of the habitat is pressurized, meaning it wants to expand like a balloon. Therefore, we needed a shape that could efficiently hold back all that pressure. We decided to reduce the diameters at the ends to minimize structural stresses, resulting in an egg shape.
After deciding on the shape, they had to choose the material. The material is crucial because it needs to be suitable for the challenges of Mars and something that can be produced on-site. They chose a polymer option due to its advantages, such as not requiring water, which would be a precious resource on Mars. Another major advantage of the thermoplastics used is that their curing process can be reversed if needed. This means they can be reheated, remelted, and redeposited.
The team carefully designed the floor plan, optimizing each room for use by astronauts. They also added a rover docking port, windows, and a skylight. They qualified for the first level and then advanced to the second construction level, where they secured second place. Once they received the award and prize money, they reinvested it back into the project, leading to the final week-long showdown. NASA invited the top two teams to print a 1/3 scale version of their habitat live in front of a panel of judges.
All the testing prior had been remote and piecemeal. They had never had the chance to print the actual prototype before the competition. The teams had two days to set up their machines before printing began, followed by just 30 hours over three days to print a complete habitat. Ideally, you would press a button and the building would construct itself. However, in reality, they had to actively supervise the entire process, with judges timing every intervention.
The first day was particularly nerve-racking because it involved the foundation, which is crucial for the stability of the entire habitat. The second day was steady printing, and they broke their previous record. On day three, they switched to a single layer thickness, allowing them to print the next seven feet in one day, which usually took two days. As the clock ticked closer to the finish line, the final task was placing the skylight, which needed to be positioned carefully to avoid falling through.
Once the time was up, the two teams had to surrender their designs. Afterward, they reflected on what could have been done differently. The judges subjected the designs to a series of structural tests, and then it was time to announce the winner. First place went to team AI Space Factory! Being announced the winner felt like graduating from a four-year degree, marking a significant chapter in their lives.
Though the competition is over, the company’s plans for MARSHA continue. It may be decades before humans go to Mars, but the sustainable building technologies developed for space might soon find applications on Earth. TERA is a habitat for Earth, made from the components of MARSHA that won the competition. It will be a fully functional home in Garrison, New York, about an hour north of their offices in Manhattan. They aim to demonstrate that sustainable building is possible and that space technology can be applied to Earth.
We are in a unique moment where there’s a space race and a climate crisis. These two issues are often seen as opposing choices: either we explore space or we focus on Earth. However, this perspective is misleading. There are ways to apply what we’ve learned in space to improve sustainability on Earth.
