NASA’s 3D Printed Habitat Challenge: Phase 3 Level 4 Final Results

▶ NASA's 3D Printed Habitat Competition Vision
• Advance the automated construction and materialstechnologies needed for fabrication of habitats on a planetary surfaceusing indigenous materials and mission recyclables
• Terrestrially, these technologies stand to revolutionize the construction industry by automating labor intensive processes and enabling rapid fabrication of large scale structures
• World’s population predicted to increase from 7.6 billion to 11.2 billion by 2100 (47 % increase) 👉• esa.un.org/unpd/wpp/Publicati...
• Requires aggressive construction practices to satisfy increased demand for affordable housing
▶ Potential of 3D Printing Technologiesfor Space and Earth
• Autonomous systems can fabricate infrastructure (potentially from indigenous materials) on precursor missions
• Can serve as a key enabling technology for exploration by reducing logistics (i.e. launch mass) and eliminating the need for crew tending of manufacturing systems
• Also has potential to address housing needs in light of unprecedented population growth
• Affordable housing globally
• Military field operations

▶ Phase III: Level 4 - Virtual Construction Competition Final Results
00:00 ● Intro
01:18 ● Hassell+ EOC’s concept
Hassell+ EOC’s concept relies on a swarm of wheeled mining robots to excavate and collect regolith for processing into feedstock. Concurrent printing along the x-y footprint of the structure by the fleet of robots enables rapid and efficient fabrication. The resulting Mars habitat has a contoured structure intended to complement the surrounding environment.

02:28 ● 1st: SEArch+/ApisCor-New York -$33,954.11
The habitat is an inward facing arch design (a hyperboloid) with two layers. High density polyethylene (a polymeric material with good properties for radiation shielding) functions as the inner layer, while the exterior is regolith. Radiation shielding is accomplished via overhangs.

7:00 ● 2nd: Zopherus-Rogers, Arkansas -$33,422.01
Lander structure encloses the printer, providing a pressurized, thermally controlled print environment for processing of the extracted materials (ice, Calcium Oxide, and Martian aggregate) into feedstock and fabrication of the first habitat module.
11:45 ● 3rd: Mars Incubator -New Haven, Connecticut -$32,623.8
A series of habitats arranged in a hub and spoke design, with the largest, primary volume at the center. Panels in the design consist of polyethylene and basalt fiber. The habitat in this design is not fabricated via continuous additive manufacturing; instead, additively manufactured panels are mechanically assembled via robotic manipulation.

Never shade when you can harvest the energy

[@MG-er6dm]

When it comes to all things space l'm yours forever. Must make me a cheap date! 😍

[@bigjohn697791]

isn't all of this form a year or two ago when NASA held a competition, and MARSHA Design won?? looks like the same teams from what I remember???

[@MG-er6dm]

With Nasa, only the best will do. The competition will be truly tough. 🙄

[@MG-er6dm]

@Perry Bee Yes! 😉

Outgassing could be a serious problem for mars colonies if proper research is not done on the moon. The first biosphere failure was due to concrete outgasses and this could be more significant if mars habitats are designed for 1/2 atmospheric pressure. Plastics also pose outgassing problems due to gasses trapped in the molecules during manufacture. Then there is the problem of biosphere equilibrium. Stuffing a closed system with Noah’s-ark animals does not ensure a desirable result as disclosed in biosphere 2 collapses. The types of materials of construction, the environment conditions and the shapes of habitats seem likely to be dominant factors. For example air ducts would favour insects and small rodent populations. Porous walls made from 3D printing regolith with binders such as cement or thermoplastics might favour several of the 1000s of types of bacteria living on our skin, to the point where they could survive and mutate on the surface of Mars consuming the energy in the perchlorates (yes there are bacteria on earth that live on it). The moon project is critical for solving these problems being only a few days away from rescue compared with 6 months for mars. America was a biosphere when Columbus brought his settlers and deseases wiped out the locals as a consequence.

As before - it brushes over a lot of stuff - ie what volume needs to be supplied from earth. The labaroratory in one is laughably a couple of microscopes (really) and who actually expects crew to last a year without closeable doors on their personal living spaces. Still think that the inflatable version will be the first used (if any) as it looks the lowest risk if not nicest (from actual liviling point of view and heaviest to transport option. Though if elon gets his rocket on then crew quarters are sorted initially and the other options look good.

[@pilkdog1]

no one mentioned anything about food though

[@jamesway5036]

Interesting. According to everything I just watched, everyone is going to be a vegetarian. I would rather see aquaponics than hydroponics. Fish is good but would get tired of after a while. So you can use the left over plant material to feed pigs and chickens. Who doesn’t like eggs and bacon for any meal?

[@jaredcoates3273]

I’m sure they will eventually. Starting with Aquaponics is a lot easier than trying to bring or rise caddie on Mars. Aquaponics is a closed loop system so once you get it started you need very little to keep it going(energy & care wise). A Aquaponics system could also be small enough to fit in a future Mars habitat. Ask any farmer and they will tell how difficult it can be to rise caddie on this planet 🌎. Now imagine trying to do that on Mars lol. We would have to provide food, an huge pressurized enclosure, energy/protection for said enclosure, and water. We could just use all those resources I just named towards more immediate issues. Astronauts eat bs dehydrated food rn so fish and veggies would be a big morale booster.

[@MichaelBehrnsMiller]

Plants ftw. You don't need eggs and bacon. What a colossal waste of resources that would be.

[@MrOckhamsRazor]

From an Occam's Razor point of view: every "contestant" came with their best foot forward, and not one of them considered the "balance-of-system" approach of using the "Olivine Sand Dunes for 3D Print Medium. The Olivine Sand Dunes - ARE THE ONLY PROCESSED SUBSTANCE ON THE PLANET IN GREAT ABUNDANCE. 3D Printing with "this consistent material", mixed with "anaerobic adhesive" to make the bonding uses less energy. I'm so sorry. but Robert Zubrin was right.

[@NicholasNerios]

We should definitely build a community of these air tight biodome homes here on earth. Not only because they're futuristic off grid awesome housing. But also so we can test longevity of habitat equipment and durability of these units. This would also give us a community as a realistic test group that is not government or organization controlled, as that kind of overseeing could effect stress levels, and effect real life results on mental health and interpersonal community connections. That and it's be like the Truman show, it's be great to watch a community of people acting like earth air and atmosphere is deadly. Good tv...

[@blackmagic3880]

I was just design a greenhouse or a small living community under it trees And running water and try design 3-D printing houses look like real housewives of anything you want

[@tomhankstomhanks2579]

No body will leave the earth,our earth is flat under closy dome.

[@comatose3788]

The words you used to describe this were totally off. I get what you're doing here but, sending people to go live in a tree house is a terrible ideal for long term dwelling. A tailor home has better living and space than this. Also that design is time tested and simplistic to create. That should have been the go to design.
