Additive solutions for space

The new generation of rocket engines is a big step in space history. Additive technologies and their advantages are the key to more sustainable engines. Learn about solutions in the space industry.

Space solutions

Complex components for rocket engines

  • New companies, technologies and materials are entering the market, making space travel cheaper and more sustainable than ever before 
  • Rockets become more sustainable thanks, among other things, to the reusability of booster stages
  • The digitalised world of today is connected more than ever before, including autonomous driving or fast internet everywhere
  • This has led to increasing numbers of satellites in orbit: by 2030, it is estimated that more than 30,000 satellites are expected to be in orbit

We support you with long-standing experience from decades!​

With our 20 years legacy in production for rocket propulsion,  we are a reliable partner in the development of new engines. We offer serial production of large additive manufactured components such as combustion chambers, with extremely complex geometries in proven NADCAP quality levels.

Ariane Group and GF Casting Solutions

For about 20 years, GF Casting Solutions has been supplying the Ariane Group, among others, with highly complex casting solutions.

  • More than 25 different GF components per launch have already traveled into space.
  • They can be found in the Vulcain 2 and Vinci engines, which were successfully tested and qualified in 2018 and 2019. 
  • The last launch of the Ariane 5 rocket took place in December 2021, carrying the James Webb Space Telescope into space from the Guiana Space Center. 
  • The GF components can be found in the new generation of Ariane (Ariane 6) as well.

In-house development and validation expertise
Our central R&D team can set up and optimize your solution - for additive manufacturing as well as for casting processes.
  • Characterization of material properties ​

  • Support and consulting in the product development process ​

  • Additive Manufacturing oriented and compliant designs ​

  • Integration of additional functions and neighbour parts​

  • Topology optimization and FEM simulation ​

  • Static and dynamic validation of components also under thermal boundary conditions​

  • Leakage testing ​

  • Metallurgical analysis of components

High design freedom
Complex and extreme shapes from thick to hollow and thin-walled in one part.
  • Better design possibilities even compared to casting
  • Extreme shapes including hollow structures and very thin walls
  • Very complex shapes from thick to thin in one part
  • Topological optimization: Reducing weight and material
High functional integration
With product development and process expertise, we can integrate multiple single parts into one design.
  • Integrating different parts into single parts into one design
  • Reduction of welding for joint activities and process steps, e.g. tooling or machining processes
Optimized part cooling
Additive manufacturing enables functions such as optimized cooling and can be applied exactly where it is needed.
  • Conformal cooling channels in near-netshape design
  • Optimized rooling rips
  • Old design needed many different manufacturing processes: additive design reduces the number of steps drastically
  • Cost advantage: not only within the geometry and performance of the application but cost savings through the simplification of the supply chain
High freedom in surface geometry & design
Maximal design freedom thanks to additive manufacturing.
  • Surface enlargement to achieve improved cooling of the component
  • Rip structure to reinforce the component
  • Flow optimization on the surface
    • Impact on air- or liquid flow
  • Cost-neutral feature
Bionic design
Bionic design means shaping the structure of a component based on the model of nature.
  • Shaping the structure based on the model of nature
  • High strength components with reduced material and weight
  • Sustainable and cost efficient
Material properties
The tensile strength of additive manufacturing material is higher and the microstructure is finer than casting.
  • Density: almost no inner porosities (in AM evenly >99.5)

  • Depending on material and scope, AM can avoid HIP-treatment (cost intensive process step) ​

  • Microstructure is finer than cast ones: the tensile strength of AM material is higher​

  • High repeatability in Additive Manufacturing 

Consulting & development services

We team up with you! We offer full R&D Service, including material, process and design development; and excellent project management. We consult and support during the set-up of specifications.

Cost-efficient all-in-one solution

We offer all post-processes in-house (HT, ST, non-destructive testing) and combine more than 20 years experience in casting parts for rocket propulsion with high-end additive maufacturing technology. Our transparent and reliable services and cost structures allow you to fully focus on the race to space.

We accelerare your time-to-market

Need to speed up your manufacturing processes? Benefit from fast turnaround time and a single point of contact: From the concept to the serial production. Our processes are independent from third parties: All processes from development to finishing take place under one roof.

Big parts or high quantity

Part size or quantity - We think big! In our 500 x 500 x 500 mm printing space, big and heavy parts are possible as well as small parts in big volumes (part quantity in one print job).

Best choice of technology

Finding the best solution! We make objective & reliable technical decisions regarding manufacturing technology (additive manufacturing vs. casting) and have experience in customer applications, processes and production costs. Both technologies and all post-processing steps happen under one roof.

Fully certified value chain

Quality you can rely on! Our complete additive manufacturing and follow-up processes are certified according to EN 9100 and Nadcap. Our trained and experienced teams take care of handling critical and complex parts requiring the higest standards.

Additive manufacturing process steps

Contact us

Print job preparation

With state-of-the-art tools and proven expertise, our additive manufacturing team takes care of the print job preparation to make sure that the process can run properly.
