SpaceX Optimizes Raptor 3 Engine With the Help of DfAM and 3D Printing

Elon Musk has not only caused a stir in the last week with inflammatory statements on social issues as well as his growing support for Donald Trump’s re-election, but also with a new announcement about the production of the Raptor 3 engine by SpaceX, his aerospace company based in Hawthorne, California. More specifically, it seems that this new SpaceX engine has been further improved using metal 3D printing and DfAM. But how?

For those who may not be closely following the new commercial space race, SpaceX is developing the Raptor rocket engine for its Starship mission. The engine will use a full-flow staged combustion cycle to power a rocket. SpaceX has already unveiled two versions of Raptor, but the latest third edition stands out for its slimmed-down design and improved features.

Raptor 3 has a simplified and optimized design. This was achieved through AM and DfAM, among other things

According to SpaceX, the Raptor 3 engine will have integrated cooling and secondary flow circuits. The engineers have succeeded in designing Raptor 3 in such a way that many of the otherwise external components could be relocated to the inside. This eliminates the need for bolted connections and heat shields, helping to reduce weight as well as streamline the look of the engine.
