How to make 3D printing spacesuit? NASA invests $750000

Researchers at the University of North Dakota received a $750000 grant from NASA to develop a 3D printed spacesuit. Working with staff from Marshall, Johnson and Kennedy Space centers, Pablo De Le ó n, professor and director of the Department of space research at North Dakota University, will conduct a three-year research and development project on the feasibility of this concept. The additive garment will be set to the ndx-3 strap, will be manufactured using a combination of flexible polymers, and will eventually be compared with the traditional spacesuit through motion capture testing. < / P > < p > & quot; so far, all the pressure resistant and spacesuits have been made using traditional sewing techniques, explains Le ó n. &They take thousands of hours of highly skilled tailors to build a spacesuit, and they are very fragile. It’s important to rethink how space suits are made, and we’ve potentially found that 3D printing can help solve this problem. &As we enter low earth orbit, astronauts will need a reliable way to repair and adjust their equipment. &Over the past 70 years, space suits have been basically built in the same way, using traditional sewing techniques to sew together pieces of polyurethane nylon, various metals and wearable polymers. This process takes thousands of hours for skilled tailors to complete, and even finished garments are ancient technology compared to modern aerospace standards. < / P > < p > What’s more, this kind of spacesuit is not cost-effective. The production cost of each spacesuit is about $2 million, and because it is tailored for each astronaut, it can’t be reused. A few years ago, und started working with NASA to change the way space suits are made, with the aim of designing an enhanced, more cost-effective alternative design. < / P > < p > although Professor de Leon and his teachers have been working on this project for some time, they recently chose to incorporate 3D printing into the design of compression suits. When the team considered the prospect of deep space exploration, they switched to rapid prototyping and won a contract from NASA. < / P > < p > < p > & quot; on Mars and beyond, astronauts do not expect an army of tailors or stitchers in their planetary habitat to take care of their spacesuits, and it will take more than a year to get parts from mission control center. &Professor de Leon explained. < / P > < p > & quot; so what we’ll try to do is mainly use 3D printing to make pressurized spacesuits, he added. &NASA has decided to fund our lab because it is possible that this could change the way space suits are made in the future and help reduce reliance on the earth, one of the agency’s goals. &Under the three-year NASA contract, the und team will evaluate the potential of rapid manufacturing technology in the design of space suits by developing and 3D printing a complete garment. Although the researchers are still in the early stages of the design process, they have modeled their ideal appearance and conducted extensive material evaluations. < / P > < p > at first, the team’s design was rejected because & quot; was too green & quot; but they improved the technology to use a range of different flexible filament print and pressure test components, and now NASA has asked for a complete prototype. As the project progresses, UD’s space division will work more closely with NASA to pool expertise and leverage the agency’s advanced 3D printing technology. < / P > < p > & quot; in the past, we had a very close relationship with NASA’s center, and for this particular project, we will need their expertise, investment, and equipment, said Le ó n. &NASA has been a pioneer in 3D printing for decades. It has some of the most advanced equipment and the best experts to help us solve some of the problems we will find in this project. &Quote; < / P > < p > & quot; we will work with Marshall, Johnson and Kennedy Space centers because they have expertise in many areas, such as the equipment we will use to develop prototypes and print prototypes. &Once the team has created their additive prototype, they will conduct a series of motion capture tests to compare its performance with the traditional flight suit. Since the suit was designed for use on Mars, motion capture tests will simulate conditions in outer space, allowing researchers to accurately measure its reliability. < / P > < p > factors such as the flexibility, mobility and walking kinematics of the suit will be closely monitored during the period to ensure that the suit is as easy to move as possible. At the end of the project, a customized prototype will be produced using body scanning technology to design a space suit that is fully suitable for future astronauts. < / P > < p > < p > & quot; we think that for a long-term space flight, it is better to have a suit tailored for you than to take a one size fits all approach. &Professor de Leon concluded. &If you use traditional technology, it’s expensive and very difficult, but with additive manufacturing, you can do it. &Over the years, NASA has commissioned a number of research projects to study the potential of 3D printing in the manufacture of space suits, and to develop various prototypes along the way. < / P > < p > as early as 2015, NASA announced that its Z-2 prototype spacesuit would be produced with 3D scanning and rapid prototyping technology. The spacesuit itself is designed to be made of high durability composite materials to achieve greater mobility and protect the wearer from the harsh environment of space. < / P > < p > recently, in January 2018, the Austrian space forum tested the spacesuit as part of a one month simulated Mars field mission. As part of the assessment, scientists from 25 countries around the world traveled to a barren area of Oman to simulate conditions on the red planet. < / P > < p > elsewhere, Raul polit Casillas, a systems engineer at NASA’s Jet Propulsion Laboratory, outlined potential aerospace applications like chained 3D printing materials. According to the technician, the additive fabric can be used as a shielding device for spacecraft, or it can be scaled down to provide protection for astronauts in the form of spacesuits.
