1. An apparatus for additive manufacturing of a three-dimensional object, comprising:
a supply of thermoplastic material;
a supply of thermoset material;
a supply of continuous strand material;
a nozzle configured to receive the thermoplastic material, the thermoset material, and the continuous strand material;
a heater associated with the nozzle and configured to liquefy the thermoplastic material inside the nozzle;
an automated mechanical apparatus connected to the nozzle; and
at least one processing unit programmed to control the automated mechanical apparatus to move the nozzle while a composite material including the continuous strand material coated with the thermoplastic and thermoset materials discharges from the nozzle.
