World first: a hollow propeller blade produced by 3D printing!
There is no doubt about it: the digital revolution is well underway in the transport industry! Naval Group, a French company specialised in naval defence and renewable maritime energy, has produced a 300kg hollow propeller blade in stainless steel using 3D printing! This world first gives rise to interesting industrial perspectives in the naval and aviation fields.
Printing hollow parts opens up very interesting possibilities for designers to improve propeller performance.
The propeller that is printing our future
Less fuel, fewer emissions, less noise … using additive manufacturing to produce propellers responds to major environmental issues in the transport sector. Presently, with a growing number of future mobility projects confirming a big comeback in propellers (read our article the future of aviation), this innovation is opening up opportunities for promising industrial developments in the aeronautical sector.
