MIT StrutCode Machine-Readable Data Laser Cut Objects
MIT CSAIL researchers have developed StrutCode, a system that can embed machine-readable data in laser-cut objects and be machined in minutes rather than hours like when using a traditional 3D printer. You can use any device, such as smartphones, with RGB cameras to read this data.



The researchers decided to test StrutCode first with objects made of wood, like furniture, picture frames, flowerpots, and toys. They discovered that to retain structural integrity, the best method was to embed the data directly on joints. A second method involves using “living hinges”, or a type of joint made by taking a flat, rigid piece of material and making it bendable by cutting a series of parallel, vertical lines.

In the realm of materials and design, there is often an inclination to associate novelty and innovation with entirely new materials or manufacturing techniques,” said Elvin Karana, a professor of materials innovation and design at the Delft University of Technology.
