A team led by Harvard and Tokyo University scientists has created an innovative algorithm that designs expandable three-dimensional lattices, combining principles from origami and kirigami with new linkage-based structures to produce dynamic, collapsible shapes.
- Algorithm designs complex expandable scissored lattices
- Structures produced via multi-material 3D printing
- Applications include compact, shape-shifting tools and habitats
What happened
Researchers from Harvard University and Tokyo University have developed a new algorithm to create expandable 3D lattices inspired by both origami and kirigami, but instead of using folds or cuts as building blocks, their designs use rods connected by scissored joints. These dynamic structures can contract and expand similarly to Hoberman spheres, a type of kinetic lattice made of joint-linked rods.
The team used the algorithm to design and physically assemble various complex shapes such as helices, toroids, and unique forms they call “eggboxes.” Production was achieved using advanced multi-material 3D printing techniques. This approach allows incremental, local construction of lattices by adding connections one by one, controlled by only a small set of design parameters.
Why it feels good
This novel method of design offers new possibilities for collapsible objects, which are especially valuable when volume constraints are critical—such as in submarines, cargo planes, or spacecraft. Collapsible designs can significantly save space and weight, enabling more efficient transportation and deployment of tools, habitats, and other important gear.
Beyond practicality, these pantographic lattices also bring a geometric beauty that could inspire designers and engineers to rethink everyday items as dynamic and adaptable. The structures are not only useful but also visually elegant, turning functional design into art and encouraging creative, shape-shifting products.
What to enjoy or watch next
Keep an eye on future applications of this technology, as the team’s work hints at potential uses in collapsible furniture, surgical implants, spacecraft components, and even innovative wearable devices like spacesuits or flying wings. As the research progresses, we may soon see everyday objects taking on flexible, transformative forms that were once only imaginable in science fiction.
For those fascinated by design, mathematics, and engineering, this development highlights how ancient art forms can inspire cutting-edge technology, blending tradition with innovation. Watching how these expandable lattices evolve in practical and artistic contexts promises an exciting journey in both science and design.
