Gem-gum
From apm
Disambiguation page
- Gemstone based metamaterial. Gem-gum as an intentionally paradoxical concrete example of
a mechanical metamaterial with vastly different properties to the base material. With a catchy name. - The defining traits of gem-gum-tec. What gem, gum, and gem-gum refers to.

Be aware that:
⚠️ Diamondoid nanoscale machinery is not at all jelly like floppy as molecular dynamics simulations may misleadingly suggest.
This is NOT what gum in gem-gum refers to. High simulations speeds are to blame.

Actually at nominal proposed speeds (few mm/s) nanomachinery bends and deflects LESS from machine motions than even everyday metal macromachinery does.
That's due to the scaling law of same relative deflections across scales.
