What is it about?
Lattices are intricate structures made of unit-cell building blocks repeated into larger structures. They are often 3D printed and can have highly unconventional properties. This paper looks at generating lattices which, when compressed under a load, hold their shape even when the force is removed.

Why is it important?
Due to their exotic properties, these structures have broad applications spanning from grippers in robotic hands to aircraft wings that can change shape mid-flight. The approach in this paper automates the design of these lattices so that engineers can more easily apply them.
Perspectives
This work pushes the boundaries of what is currently possible for designing these structures. Hopefully this new approach will open up many exciting possibilities and applications.
