Technology & Products
Key Products
Additively manufactured combustion chambers; Rocket engine components; Large-scale structural parts for launch vehicles
Technological Advantage
Proprietary process knowledge and qualification for high-performance nickel alloys (e.g., Inconel) in large-format PBF-LB and DED-Arc, developed through partnerships with Nikon SLM Solutions and DLR. Advantage is protected by internal trade secrets and process control rather than public patents.
Differentiation
Value Proposition
Reduces lead times and costs for complex, high-performance rocket engine components, enabling more integrated and scalable propulsion architectures for future reusable launch systems.
How They Differentiate
As an integrated launch vehicle manufacturer, competes on deep vertical integration of AM into final flight hardware, not on selling machines or services. Focus is on internal production for Ariane 6 and future programs, unlike pure-play AM service bureaus.
Market & Competition
Target Customers
European Space Agency (ESA), internal ArianeGroup launch programs (e.g., Ariane 6)
Industry Verticals
Aerospace; Defense; Space
Competitors
GE Additive; EOS; 3D Systems; Norsk Titanium
Growth & Milestones
Growth Metrics
Produced over 1,000 additively manufactured parts for the Ariane 6 launcher, including the first full-scale, additively manufactured combustion chamber (Prometheus engine) which reduced part count from 248 to 1 and cut production time by 50%. The company has scaled its AM capacity to produce critical components for multiple launch vehicle programs.
Major Milestones
First fully 3D-printed combustion chamber successfully hot-fired at DLR Lampoldshausen (2023); Strategic partnership with Nikon SLM Solutions for ultra-large-scale AM for space components
Notable Customers
European Space Agency (ESA); Ariane 6 program
