MIT Builds Lightweight Aluminum Structures From Origami
Researchers use folded aluminum blocks joined with hand tools to create rigid, lightweight shells without welding.
Updated on Nov. 6, 2026 in Materials Science
MIT researchers developed origami-inspired aluminum building blocks that form lightweight, rigid structures without interior columns. The team assembled a 23-foot aluminum sculpture that hangs in the Boston Public Library atrium.
Why it matters
The method aims to build strong structures while minimizing material use, and blocks can ship flat as panels for shaping on site. Simulations suggest the approach could yield stiffer shells than some other origami-based methods.
Simulations showed shells about 3.5 times stiffer than some other origami-based methods, using roughly two-thirds of the material. The team has not yet confirmed these results in full-scale built structures.
The players
MIT Center for Bits and Atoms
A research center at the Massachusetts Institute of Technology where the origami-inspired building method was developed.
Ron Resch
An artist and designer whose folding patterns from the 1960s form the basis of the new aluminum block method.
The details
Each block is cut from flat aluminum sheets by a computer-controlled milling machine, then folded into shape and joined with ordinary hand tools such as screwdrivers, without welding equipment. The method builds on folded patterns developed by Ron Resch in the 1960s, pairing two tripod-shaped units into one block that joins into a hexagonal grid of interwoven beams.

The Big Picture
The work extends Ron Resch's folded patterns from the 1960s into a structural metal method that joins small units into rigid shells. It shifts those origami forms from paper and art toward load-bearing architecture.
If the folded aluminum method performs in real buildings as simulations suggest, it could lead to lighter structures that use less metal. Shipping flat panels that are shaped by hand could also simplify transport to relief sites.
The takeaway
Lightweight structures built from folded metal may reduce material use while keeping stiffness, but the approach still needs testing at architectural scale before it can be relied on in buildings.
