Abstract

A metal matrix composite (MMC) tool includes a mesoscale-reinforced hard composite portion that comprises reinforcing particles and mesoscale reinforcing structures dispersed in a binder material. The mesoscale reinforcing structures are printed using at least one additive manufacturing technique and are larger than an average powder-size distribution of the reinforcing particles.
