Hydroforming can do many of these shapes with a lower per unit cost at high batch sizes, except the double walled spring design. However this is excellent for specialized solutions.
Fluid bellows have directional flow by means of a floating tube section in the centre that is fixed to one end of the bellow. So the ribs of the bellows doesn’t cause disruption to the flow of the fluid.
Similar to @intagliode's response, Günter Kappler from the video replied: "That’s a good point. Conventional circular bellows also have a problem with a wavy diameter. Often, a guide tube welded onto the flange is used to guide the flow. The same solution is possible here: inserting a (conventional) circular inner guide tube welded onto the flange."
Also, we have more about these bellows on The Cool Parts Show All Access. Here is a more detailed explanation from Kappler about the testing he performed on the part: www.additivemanufacturing.media/articles/more-on-testing-a-3d-printed-metal-bellows-the-cool-parts-show-all-access
wouldn't this bellow work as a piston cylinder with perfect seal ? no need to piston ring or worry about leak if every thing is contain. Although not sure if the stretch of bellow wall cylinder will cause sufficient energy lose to make it not worth while compare to traditional piston cylinder.
*This is great, I last use a flexible stainless steel bellows on a fiber optic rotating joint that was pressure compensated for subsea use in my job as subsea robotics engineer, printing these is excellent.*

Very cool! 😄
The solution is pretty awesome, however if some sort of fluid has to flow through a bellow, square shape will add friction, No??

Flexible metal wow🎉
What is the material? Inconel 718?
Stainless steel 316L / 1.4404
