ORNL team combines 3D printing and casting to make stronger, damage-tolerant composite parts

Researchers from the Oak Ridge National Laboratory (ORNL) and Rice University in Houston, Texas have developed a novel process for creating “damage-tolerant components” made from multiple materials. The innovative process combines 3D printing with traditional casting methods. Model of a 3D printed preform structure The research project, entitled “Damage-tolerant metallic composites via melt infiltration of additively manufactured preforms,” shows how the combination of 3D printing with casting can result in optimized parts that are stronger than if they were 3D printed or casted. As the researchers explain, the novel two-step process helps to overcome “issues with intermetallic formation, cracking, […]
