Satellite Detail Produced through 3D Printing by RUSAL Successfully Works in Space

Moscow, 1 February 2021 – RUSAL (SEHK: 486; Moscow Exchange: RUAL), a leading global aluminium producer, announces the successful operation of a 3D-printed casing installed onto Yarilo satellite. The thermoregulatory casing of the gamma-ray detector was developed at the Skolkovo Institute of Science and Technology and was produced at the Centre of Additive Technologies based on the Institute of Light Materials and Technologies (ILM&T) from a new aluminum powder alloy developed by the institute's specialists.

The temperature-regulating casing of the gamma-ray detector, produced on a 3D printer, has been installed onto one of the two Yarilo research satellites launched into space in 2020. This is a unique space project for the Bauman Moscow State Technical University in partnership with the Lebedev Physical Institute of the Russian Academy of Sciences and the Institute of Nuclear Physics of Moscow State University. Yarilo satellites’ mission is to explore the sun and weather in space. The detail printed in ILM&T is an important part of the satellite, preventing overheating of the main equipment and ensuring its stable operation.

The new RS-333 aluminum powder alloy developed by specialists of the RUSAL Institute of Light Materials and Technologies was used for 3D printing. The new alloy countered the issue with low technological efficiency when printing with the use of aluminum alloys ligated by magnesium and silicon. These alloys, meanwhile, have good thermal conductivity and high solidity. The design of the part has been specifically optimized for 3D printing by the research team of the Skolkovo Institute of Science and Technology. As shown by ground tests, and then proved by operation in space, the new net structure printed with a new high-heat-conducting alloy through 3D printing allowed a 20% weight reduction with a 25% increase in heat flow, which is the main indicator of the effectiveness of parts involved in thermal regulation.

"Testing additive technologies in space is a unique opportunity to showcase the prospects and reliability of using aluminum alloys and 3D printing in creating such an important node, on which the stable functioning of the entire unit depends. We are confident that this experience will be useful not only for expanding the implementation of 3D-printed parts in scientific research, but also for practical application in numerous high-tech industries such as automotive, computer manufacturing, home appliances, and mechanical engineering,” said Victor Mann, Chief Technical Officer at RUSAL.

The ILM&T was founded by RUSAL in 2017. The primary objective of the Institute being to develop, innovate and launch new varieties of aluminium-based products and materials into the market.
