Automated post-processing of 3D-printed components for the aerospace industry

The Exploration Company, an international space company with a focus on sustainability, has invested in the automated post-processing of 3D-printed components. With the Solukon SFM-AT350-E and SPR Pathfinder software, the company is using state-of-the-art technologies to make the production of components for reusable space capsules more efficient and resource-saving.

The Solukon SFM-AT350-E is specially designed for the depowdering of medium-sized, beam-melted metal parts. It uses piezoelectric frequency excitation to remove powder residues particularly gently and effectively. The SPR-Pathfinder software automatically calculates the optimum movement sequence of the component so that even complex geometries can be completely freed of powder. This simulation enables engineers to identify and optimize potential challenges in post-processing as early as the design phase.

“With the SPR-Pathfinder software, we calculate in advance how the component needs to be moved so that all the powder runs out. This allows us to achieve reliable cleaning results and clean components in series,” says Maxi Strixner, Senior Additive Manufacturing Engineer at Exploration Company.

The technology is particularly relevant for the production of components for the Nyx space capsule, which places strict demands on precision and purity. Powder residues in components could jeopardize the safe operation of the space capsule, which is why powder removal is a key part of the production process.

Another advantage of the Solukon system is its sustainability. The collected powder is processed without contamination and can be reused. Compared to conventional cleaning systems, the piezoelectric technology significantly reduces compressed air consumption. This approach supports the Exploration Company’s sustainable vision, which aims to develop reusable space capsules.

“Our main focus is on the development of reusable space capsules for the transportation of payloads and humans into space,” says CEO and founder Hélène Huby.
