1. A system comprising:
a reservoir for receiving a thermoset;
a microwave resonance cavity comprising an outer conductor and a tubular or annular inner conductor, said inner conductor comprising a nozzle disposed therein through which the thermoset can pass, said nozzle in fluid communication with said reservoir to receive the thermoset;
a controller comprising a processor and memory, said processor executing instruction to:
cause the thermoset to be transferred from said reservoir to said microwave resonance cavity; and
cause a microwave source to provide microwave energy into said microwave resonance cavity to produce a standing wave at a point of deposition to heat the thermoset after the thermoset exits said microwave resonance cavity, accelerating the chemical reaction and solidifying the thermoset.
