Three winning 3D-printed designs showcase possible human homes on Mars
(Nanowerk News) MakerBot and NASA’s Jet Propulsion Laboratory want to bring 3D printing to the Red Planet! While Mars is not yet home to humans, 3D printing using materials on Mars or resources brought from Earth would likely help future Mars explorers survive. MakerBot and JPL teamed up to challenge the 3D printing and design community to come up with designs for a Thingiverse Mars Base that could theoretically support human life on the Red Planet. 228 original designs were uploaded to Thingiverse.com, MakerBot’s 3D design community for discovering, printing and sharing 3D models. The enthusiasm behind these contributions was out of this world, as detailed and scientific descriptions often accompanied the innovative designs. All of the submitted designs were 3D printed on a MakerBot® Replicator® 3D Printer and then reviewed by scientific and engineering staff at JPL, who used their expert knowledge and experience to help select the final three winners.

Noah’s solution approaches the harsh Mars climate without sacrificing the comforts of home, with a structure designed to protect its inhabitants from frigid temperatures and cosmic radiation. Noah chose to use the tessellating hexagon shape as a form factor, due to its compactness and modular potential. His description of the design includes radiation shielding, an underground heated water insulator, and an air purification system. Noah states, “This is quite a multifaceted challenge. I have tried to think through the theory of my design as much as possible and prove it with a printed model. I designed something that I would feel happy living in for a few years (at least).”
This pyramid design focuses on multi-functional systems that ensure limited resources are reused as much as possible, with energy produced from a mirror-based solar collector. Valcrow describes his Martian Pyramid as taking inspiration from the pyramids on Earth, some of the most iconic, longest standing structures. Valcrow notes the pyramid’s stable triangular geometry has proven its durability through the ages in ancient buildings around the world and demonstrated its weather resistance in tent and teepee designs. This model is intended to be an architectural cutout view, where the generator room and water storage areas are clear to the viewer.
Third place is awarded to Thingiverse user Chris Starr (Cstarrman) for his Mars Acropolis, which incorporates ancient Greek architectural elements with modern research facility features.

This futuristic structure draws energy from solar panels, includes three massive greenhouses, and is designed to ensure that limited resources are not wasted. Chris created his solution by taking cues from the ancient Greek Acropolis of Athens. The Mars Acropolis is a three-tiered structure. Its outer wall serves as a protective barrier. It’s foundation is built atop a mixture of soil from Earth and Mars. The habitat serves as a mass research facility to explore and develop means for additional colonization of the planet.
“We really loved seeing how the designs in the Mars Base Challenge were often inspired by structures here on Earth that have withstood the passage of time and harsh weather elements,” noted Bre Pettis, CEO of MakerBot. “It was challenging to select just three winners from the 228 entries. We were happy to have the experts from JPL on board to help with the judging process, as they took this challenge very seriously. Overall, this was a very inspiring challenge.”
JPL, in coordination with its Imagine Mars Project and IT Chief Technology and Innovation Office, evaluated the designs based on research done by participants about what it would take humans to survive in the extreme environment on Mars, general feasibility, and design thinking. MakerBot took those inputs into consideration, while testing printability, replicability, and other 3D design aspects to select the final winners.
The first place winner of the MakerBot and NASA/JPL Thingiverse Mars Base Challenge will receive a MakerBot Replicator Desktop 3D Printer. Second and third place winners will be awarded spools of MakerBot PLA Filament. All of the Mars Base Challenge designs can be viewed, downloaded and 3D printed from Thingiverse.com, the world’s largest 3D printing community with more than 300,000 digital designs available.
