More on Testing a 3D Printed Metal Bellows: The Cool Parts Show All Access
Günter Kappler, designer of the metal bellows in episode 64, describes the extent of the testing that has gone into validating the performance of these 3D printed parts.
Günter Kappler, designer of the metal bellows in episode 64 of The Cool Parts Show, describes the extent of the testing that has gone into validating the performance of the flexible metal bellows made through additive manufacturing. This extended clip is more detailed than what we were able to include in the regular episode.
More from Dr. Kappler
“The maximum elongation or compression of a metal bellows is usually specified for 1k, 10k, 100k or 1mio cycles. So far we have successfully carried out vibration/fatigue tests with 1k and 10k. We have increased the maximum change in length by 50% compared to conventional metal bellows. For example, the test specimens with 9 bellows on a length of 60mm have successfully realized +/- 15mm for 1k cycles. And more tests will follow.”
