Space exploration and additive manufacturing go together like Oreos and milk. Over the last two years, we have seen an influx of companies within the aerospace industry begin adopting 3D printing as a way to cut their costs by reducing payload weights, or in a couple of cases, the actual weight of a spacecraft. Elon Musk is using additive manufacturing to lighten the launch load for SpaceX missions, while NASA is exploring the technology in a variety of ways as well.
Swedish company RUAG, known for their highly reliable on-board satellite equipment, which includes microwave electronics, antennas, separation systems, and various other components, has turned their attention to 3D printing as a means of production.
RUAG’s Space division has teamed up with Altair, a US company known for their design optimization skills, as well as Germany-based EOS, which has vast experience producing light-weight metal-alloy components via additive manufacturing technology.
3D Printed Antenna Support
The goal for RUAG Space is to produce a lighter, more efficient antenna support for an Earth Observation (EO) satellite, a successor to the Sentinel-1 radar satellite. To get started the company relied upon Altair’s software to redesign the support structure using as little material as possible and exploit the freedom of design enabled through the use of 3D Printing. Once a design was agreed upon, they turned to EOS which printed the finished component via a powder-bed laser sintering machine.
“Our goal is to fit Sentinel-1 successors with antenna supports that have been manufactured using a 3D printer,” said RUAG Space CTO Michael Pavloff. “3D printing has enormous potential for our business, and we’re currently in the process of developing further space applications.”
RUAG Space managed to produce a part which was half the weight of that used on the Sentinel-1, while possessing better rigidity. The antenna support was a staggering 40cm in length, making it the largest known object ever 3D printed via a powder-bed laser sintering system. A rigorous set of tests are being conducted on the support, which should conclude by year’s end.
“The collaboration with RUAG Space and EOS allows us to deliver even more innovative end-to-end design and optimization processes to exploit the benefits of additive
manufacturing.” said Altair Managing Director Pietro Cervellera.
Future applications of this technology could mean more than the production of a single satellite component. In fact, entire sections of a satellite may one day be printed out, including their reflectors, heating pipes, harnesses, and other components which could be integrated directly into the underlying structure of the satellite, printed in one piece.
There is no doubt that this incredible technology will continue to save those involved in the aerospace industry quite a bit of money, while also reducing the amount of raw material needed for the production of various items.
