Additive Manufacturing certification is exactly what the Aerospace industry needs, as it redefines design and material possibilities. Researchers already work with 3D printing certification on Earth and the potential uses of it in space. The next step? Testing it in orbit and on Mars. It’s been a while since we sent our 3D printed satellite into space, what has changed since then?
Using 3D printing certification in space can be challenging, but not impossible. Additive Manufacturing certification brings more benefits to the aerospace industry than disadvantages, so scientists and engineers all around the world are not giving up on this technology. Certainly, AM gives the possibility to use new materials that no other technology could produce objects with. We already discussed an incredible project of 3D printing certification with moondust.
Other than that, Additive Manufacturing certification also allows for the creation of lightweight structures, which is absolutely crucial in the aerospace industry, even if the 3D printing certification process happens in space. 3D printed mechanical parts are strong and robust and can be produced fast and be lightweight with lattice structures. Let’s see which of these benefits are already used by scientists!
The eco 3D printer in space
Just in November, a new mission was launched to orbiting lab by NASA. The Northrop Grumman Cygnus is a resupply flight carrying not only Virtual Reality devices and simulated stardust, but also an eco 3D printer to the space station. The goal is to develop and test methods to use 3D printing certification in space in zero gravity and recycle the material found on stars. This is the first time ever to perform such an experiment in space.
The challenging aspect of 3D printing certification in space is the material supply. We simply can’t ship it every week. However, if we find a way to reuse the material, that would open a whole new chapter for 3D printing certification in space. The latest machine is capable of turning waste plastic material into high-quality filament. This amazing development is a huge step for 3D printing certification in space. It allows for sustainable and eco-friendly production and shorter reparation time for 3D printed parts.
The recycled material needs to pass rigoristic quality control checks to assure the parts won’t break. This is exactly what is being tested in space right now! Another benefit of this development would be the elimination of feedstock sent from Earth. If we could use stardust or moondust to 3D print, we wouldn’t have a problem of running out of the filament. Sounds unbelievable? Follow the blog and find out 3D printing certification on Mars!
NASA’s plans for Mars
Back in 2014, NASA announced the 3D printed Habitat Competition. The goal of it was for the contestants to develop sustainable and independent shelters for 4 astronauts who would start a mission on Mars. The teams had to find solutions to transporting printing materials from space stations, address the problem of different landscapes and atmospheres between Earth and Mars and they all had to use Additive Manufacturing certification technologies. This past summer, NASA selected 5 winners. Let’s discover their ideas of humanity colonizing Mars!
Bioinspired egg-like houses
Nature finds perfect solutions and creates ideal structures to overcome any problems it might meet. Mankind has been observing nature, learning from it, and mimicking it to come up with answers to our production and manufacturing problems. This process is called biomimicry. And this is exactly the way that the winning Team Zopherus led their project.
The group from Arkansas created a modular habitat which would be 3D printed without any need for humans to interfere, they would be safe at a space station waiting for the habitat to be produced. The concept is for a lander to scan the surroundings and pick the best place to start 3D printing certification. It would use the soil surrounding it to build houses, labs, gyms and other recreational places. Their project is eco-friendly, very independent and highly efficient for us to one day move to Mars, carrying not much more than a 3D printer.
Living in vertical structures
Second place in the competition won AI SpaceFactory. They decided to move forward with long, vertical shelters, explaining it as the best structure for the Martian surface. It also could be easily divided into different living areas for various activities. However, compared to Zopherus team, each house is separate, and built of a mixture of Martian soil and bioplastic.
The team paid a lot of attention to providing the best experience for the habitats. They emphasized how important it is for people to be able to do basic, daily life tasks. Mental health of the crew and obtaining a stable social life was taken into great consideration. With AI SpaceFactory the human aspect was the main factor around which the whole structure of habitat on Mars was created.
Shelled green area
The Kahn-Yates team also designed separated houses, however, their shape is different. Their take on the structure…
