Astra user reports AI-built virtual materials lab

A user reports having Astra build a 3D metamaterials studio from images of a biological microstructure. Metamaterials get their properties from their internal architecture. According to the account, the app included editable geometries, physics simulation, deformation and fracture experiments, and STL export for 3D printing. The user then asked Astra to search for designs using its own app. The leading candidate reportedly reached about 2.1 times the reference ratio of work-to-failure to peak strength.
