Ford Motor Company and Sharrow Engineering have joined forces to transform the manufacturing of the Sharrow propeller. The process, which previously required 130 days, is now completed in just two weeks. Announced on April 9, 2026, the project uses sand casting with 3D printing, supported by Michigan Central in Detroit, to achieve high-volume production.
3D Casting: from sand to propeller in record time 🚀
After nine months of design adaptation, Ford applied its expertise in 3D sand casting together with regional foundries to implement the new process. The Sharrow propeller offers up to 30% more fuel efficiency and an 80% noise reduction compared to conventional propellers. The key was redesigning the parts so that 3D printing of sand molds enabled fast and precise production, eliminating long lead times.
Goodbye to noise: your marina neighbors will thank you 😌
The Sharrow propeller not only saves fuel but also reduces noise by 80%. This means you can finally leave the harbor without waking up half the neighborhood. Of course, get ready for fishermen to give you strange looks as you pass by in absolute silence. And the best part: Ford manufactures it in two weeks, so your patience is no longer an issue.
