Blade Attila | 3D printed spiral spring for Stirling free piston engines @AttilaBlade | Uploaded May 2018 | Updated October 2024, 44 seconds ago.
Don't forget to check out my 2nd channel @east-europeansmarts 🙏❤️👍
I made a flat spring as flexure bearing for free piston Stirling engine.
It was the first trial version of flexure with ABS material on my 3D printer. This is a simple printer, nothing special.
The model was created by myself from an internet picture what I found. The spirng diameter is 80 mm, the height is only 1 mm.
I printed out 4 pcs of spring also I printed 3 pieces space holders for the center and the outer line for bolts.
I hope you enjoyed the slow motion pictures too! :)
