1. An additive manufacturing apparatus comprising:
a mixer comprising an inlet and an outlet;
a reservoir in fluidic communication with the mixer such that material from the outlet of the mixer is able to flow into the reservoir and material from the reservoir is able to flow into the mixer;
a build plate disposed in parallel alignment with the reservoir; and
a reservoir pump configured to drive material from the outlet of the mixer into the reservoir through a conduit, and
drive material from the reservoir into the mixer through the conduit.
