Sirius Space Services
Colombes
Sirius Space Services is a key player in the “new space” industry, enabling small satellites to be launched in an efficient and sustainable manner. This French company has developed a range of scalable, modular-based rockets, with one booster being duplicated to offer the exact thrust power needed by the customer. Embedded in this booster is an innovative engine called STAR-1, developed by integrating all the possibilities offered by metal additive manufacturing. Thanks to the L-PBF (laser powder bed fusion) technology, which enables printing metal parts with optimized shapes and complex internal features, the STAR-1 presents an unprecedented level of efficiency, compactness, and reliability. Now focused on the serial production of their rockets, Sirius has partnered with AddUp, manufacturer of metal 3D printers, and uses the FormUp 350 machines to print engines that have best-in-class surface quality, metal properties and production repeatability.
Focused on reducing the environmental impact of satellites launches, Sirius Space Services has used L-PBF technology to design a rocket engine propelled by LOX/LCH4. An eco-friendly fuel, recent in this industry, which offers reduced energy consumption for both production and storage compared to liquid hydrogen, along with 50% reduced CO2 emissions during the flight. It also enables easy refurbishment of the engine, making the STAR-1 the first engine of its category to aim to be 100% reusable.
The Formup 350 by Addup is an additive manufacturing production machine using the Laser-Powder bed Fusion (L-PBF) technology. A powder bed is locally melted by 4 lasers, drawing on the surface the slice of a part. This routine is repeated consecutively until the height of the part is reached. Our 3D metal printer offers three recoating systems (Brush, roller, silicon blade) allowing unique flexibility to customers and maximizing the reach of the metal 3D technology. FormUp 350 machines are safe, efficient, and scalable, integrating more than ten years of experience built by AddUp and Michelin in PBF technology, with safety at the heart of our concerns.
