A 100% 3D Printed Linear Snap Action Mechanism.

A 100% 3D printed linear snap action prototype mechanism for an upcoming project.
As the name implies, the snap action in this mechanism is linear. The slide (yellow) travels between two leaf springs (white) positioned in the base (green). When operated, the cams compress the springs until the cams reach just over 50% of the designed travel length, at which point the slide snaps to the full travel position.
A rotary snap action mechanism (requiring a metal spring) is here: • A 3D Printed Rotary Sn... .
Designed using Autodesk Fusion 360, sliced using Ultimaker Cura 4.7.0, and 3D printed in PLA on Ultimaker S5s.

Could you explain for a layman what you mean by retention choice? I was wondering if this might be affected by degradation in the long run, so I'm curious as to how this design avoids that.

@TheTsunamijuan 2 жыл бұрын

@@reinux The pins holding the springs in place is what I meant by retention. If the spring was actually physically part of say the base, Even with part of it floating. It would likely fatigue over time. Mostly he avoids it by making the springs a complete separate component. Rather than letting the allure of all in one designs, (that are so tempting with a 3d printer) creating a longevity issue. Hopefully that answers your question :)

@popzct 2 жыл бұрын

Hi j a, The endpoints on the snap shaft compress the leaf spring. The amount of compression is determined by the length of the snap shaft endpoints. When the leaf spring is compressed by the snap shaft endpoints, the end points of the leaf spring expand thus the radius of the spring is enlarged. The trigonometry involved is in calculating the snap shaft endpoints and the ends of the leaf spring as when compressed, the end points extend causing the radius of the compressed leaf spring to increase. I hope this helps! Greg
