Magna Parva approached the MTC for advice and guidance on manufacturing an energy-absorbing structure for the Mars Sample Return mission using an electron beam melting (EBM) additive manufacturing process.
The structure needed to be strong enough to withstand freefall impact on re-entry, crushable enough to reduce impact shock for its own contents, and heat proof to keep the sample below a specified temperature.
The MTC has a lot of experience and knowledge about what is possible when it comes to additive manufacturing. We partner with them on a few other additive manufacturing projects, and use the additive metal manufacturing machines to help our work
Andrew Bowyer, Commercial Director and Co-founder, Magna Parva
The additive manufactured crushable structure enabled Magna Parva to assemble and mechanically test the structure for the European Space Agency’s Thermal Protection System Project.
The innovative technology, manufacturing process steps and mechanical test results have been captured and validated by theoretical analysis and FEA, allowing Magna Parva to further optimise the structure design while considering manufacturing post-processing techniques to improve accuracy and quality of the parts.
Benefits to the Client
The MTC was able to provide knowledge of the additive manufacturing tooling capabilities and detail exactly what happened during the manufacture phase, so we could record and review the process as well as design methodology for further development. It is this advancement that is helping the technological process, and giving us the manufacturing input we need
