SpaceX – SpaceX Raptor 3 Engine AM Optimization

Challenge

Raptor 3 needed to simplify the engine dramatically, reducing part count, improving thrust-to-weight, and slashing production cost for Starship's ambitious production rate targets.

Solution

Elon Musk confirmed in August 2024 that AM "internally integrates so many formerly discrete components" — enabling Raptor 3's consolidation. SpaceX is reported to have the world's most advanced internal metal 3D printing program.

Outcomes

01Raptor 3 substantially simpler than R2; cost and production rate improvements

Technologies

Laser Powder Bed Fusion
