New AI tool discovers realistic ‘metamaterials’ with unusual properties

In this video, a new artificial intelligence (AI) tool discovers realistic “metamaterials” with unusual properties. The video augments the article “Deep Learning for Size-agnostic Inverse Design of Random-network 3D Printed Mechanical Metamaterials” published in Advanced Materials. Courtesy of TU Delft.

Students build low-cost cold spray metal 3D printer prototype

Rice University students in Houston, Texas, have developed a cold spray metal 3D printing device that uses pressure and velocity instead of temperature, potentially expanding the capabilities and reducing the costs of metal additive manufacturing and repairing for complex, one-off parts.
