In the process of exploring the journey of the universe, astronauts often feel that the materials they carry into space are not sufficient. Each additional pound of weight means more fuel, and more fuel means more costly space exploration. One way to solve this problem is to find possible spacecraft manufacturing materials as much as possible. This is also the business of asteroid mining Planet Resources.
The company has not had the opportunity to confirm their ideas, but they have found ways to build a model. At this year's CES conference, Planet Resources Corporation unveiled its first 3D printed finished product made of extraterrestrial materials. Part of this 3D printed spacecraft is based on the Arkyd process.
They made a meteorite fragment that fell to Argentina 4,000 years ago and processed it with a 3D system ProX DMP 320 direct metal printer, which eventually made the spacecraft model. According to the Planet Resources team, space rock is composed of iron, nickel, and cobalt, and its composition is similar to that of refined steel. Therefore, space rock became the best foundation for the establishment of this project. To convert solid vermiculite into a printable material, the team used a plasma injector to melt and separate the vermiculite into a mass of metal powder. This mass of material is also extracted under vacuum.
Chris Lewicki, the company's CEO, explained to reporter Engadget: "This metal will be concentrated into a cloud-like substance, but it is not equivalent to a titanium pellet that has been lowered from the iron-nickel cloud." At this point, the 3d printer is ready to be The vermiculite material is printed into any programmed shape.
Although this project can be carried out smoothly on the earth, it needs to be strictly debugged to be implemented in outer space. An obvious problem is weightlessness.
Gravity keeps objects in place while printing, which is critical throughout the process. In the next project, Planet Resources will focus on making the Earth Infrared Imager satellite, which will ideally sit in the home to scan resources.
