Neri Oxman’s design lab, OXMAN, has launched O° (pronounced “O-Zero”), an innovative platform for creating 100% biodegradable, 3D-printed shoes. This project, based on a unique PHA (polyhydroxyalkanoates) biomaterial, leverages digital design and robotic manufacturing to redefine sustainable product lifecycles. The O° shoes are made from a single biomaterial and eliminate the need for petrochemicals, adhesives, and complex multi-material assembly typically involved in footwear production.
OXMAN’s platform combines 3D knitting and 3D printing, producing the shoes with virtually zero waste and minimal human intervention. The shoe’s structure is built with a knitted PHA yarn base, reinforced by a 3D-printed shell, providing support and flexibility based on kinetic data from human motion. As Oxman notes, “The O° shoe seeks to minimize harm in its design and nourish the environment in its afterlife,” leaving no microplastics as the PHA material decomposes completely back into natural bacteria.
The O° technology eliminates traditional cut-and-sew processes, resulting in a streamlined production cycle that supports local manufacturing and minimizes environmental impact. Currently, OXMAN is exploring partnerships to scale the platform, aiming to meet the rising demand for ethical and eco-friendly products in the consumer market.
