Title: Damage-tolerant metallic composites via melt infiltration of additively manufactured preforms

A facile two-step approach for 3D printing metal-metal composites with precisely controlled microstructures is described. Composites made with this approach exhibit tailorable thermal and mechanical properties as well as exceptional damage tolerance.
