Astra built a virtual materials lab and used it to search for designs, a user says

A user describes an experiment asking Astra to design metamaterials—materials whose properties depend on their internal architecture. They say the AI built a 3D studio from biological microstructure images, including tools to simulate deformation and fracture and export designs for 3D printing. The user then asked Astra to search with its own app for a high work-to-failure/peak-strength ratio. They report that the leading candidate reached about 2.1 times the reference ratio.
