Actually the clever bit is the *design* software.
And when boffins use the word "arbitrary" they mean that they can design a part to a specific size, shape or requirement, rather than a cut-and-try-and-hope-it-works process.
Keep in mind this version is made in paper.
That is not a requirement for future versions.
My instinct is the limits are set by the areal strength of the shape memory materials.
Thumbs up for clever thinking and not breaking the bank to do the research.
Biting the hand that feeds IT
