1. A metal matrix composite (MMC) tool, comprising:

  • a first layer, a second layer, and a third layer,each layer comprising a mesoscale-reinforced hard composite portion that comprises reinforcing particles and mesoscale reinforcing structures dispersed in a binder material, wherein the mesoscale reinforcing structures are printed three-dimensional polyhedra skeletal structures with an open face, the mesoscale reinforcing structures are larger than an average powder-size distribution of the reinforcing particles, wherein the mesoscale reinforcing structures are configured to have a melting point that is different than a melting point of the binder material, and wherein a concentration of the mesoscale reinforcing structures in the second layer is between concentrations of the mesoscale reinforcing structures in the first and third layers;

    wherein the MMC tool is a tool selected from the group consisting of an oilfield drill bit or cutting tool, a non-retrievable drilling component, an aluminum drill bit body, a drill-string stabilizer, a cone for a roller-cone drill bit, a model for forging dies, an arm for a fixed reamer, an arm for an expandable reamer, an internal component associated with an expandable reamer, a sleeve attachable to an uphole end of a rotary drill bit, a rotary steering tool, a logging-while-drilling tool, a measurement-while-drilling tool, a side-wall coring tool, a fishing spear, a washover tool, a rotor, a stator and/or housing for a downhole drilling motor, a blade for a downhole turbine, and any combination thereof.
