Developing low-cost materials for 3D printing larger, stronger components for the tooling, aerospace and automotive industries is the aim of a new partnership between Oak Ridge National Laboratory  (ORNL) and Illinois-based Polynt Composites USA.   The collaboration focuses on early-stage research and development of reactive materials that print at room temperature and harden through a chemical reaction that cross-links each printed layer. This approach yields stronger, more scalable printed p...
