Fleet Space Technologies and 3D Systems’ Application Innovation Group (AIG) allowed the two to architect an additive manufacturing solution that includes process development and bridge production on its DMP Flex 350, which will enable the companies to move from Fleet Space’s existing RF patch design to the small batch production in three weeks.
A DMP Flex 350 printer will be brought into service at the Fleet Space headquarters in Beverly, Adelaide, allowing the company to bring production of its patch antennas in-house.
The antennas will be used for each of the Alpha satellites operating in a constellation in low earth orbit as part of the aerospace company’s ExoSphere initiative for mining exploration with minimal environmental impact.
The Fleet Space team knew that the only way the geometry of the patch antenna design could be realised is through additive manufacturing. 3D Systems’ AIG developed print processes to produce the antenna on its DMP Flex 350 printer in two different materials, LaserForm AlSi10Mg and Al6061-RAM2.
The vacuum chamber architecture of the DMP Flex 350 maintains a low oxygen environment of <25 ppm. Argon gas consumption is heavily reduced, but the chamber architecture also produces a good surface finish with fine feature detail which minimises signal losses.
“Our work with Fleet Space Technologies is yet another example of how 3D Systems helps our aerospace customers accelerate innovation and de-risk their additive manufacturing application application development,” said Dr. Michael Shepard, Vice President, Aerospace and Defense segment, 3D Systems.
Fleet Space Technologies founder and CEO Flavia Tata Nardini, said: “Fleet’s Alpha constellation represents a significant leap forward in our mission to unlock the potential of truly global connectivity, in doing so creating global benefits for applications like making the search for critical minerals more sustainable and viable.”
Nardini added: “This technology will enable our people to create the production processes that will deliver on Fleet’s ambition to launch more than 140 low earth orbit satellites in the Alpha constellation.”
