ADDITIVE MANUFACTURING PRINTHEAD

Abstract:

A printhead for an additive manufacturing system includes a hopper, an outlet, a mixing shaft, and a drive shaft. The hopper includes an inner volume configured to store a slurry material for mixing. The outlet includes a passageway fluidly coupled with the hopper. The outlet includes an open end for discharging the slurry material to a surface through the passageway. The mixing shaft extends through the inner volume of the hopper and includes a member that extends radially outwards from the mixing shaft. The member is configured to mix the slurry material within the hopper as the mixing shaft rotates. The drive shaft extends through the inner volume of the hopper and at least partially into the passageway of the outlet. The drive shaft includes a sloped surface configured to drive the slurry material from the hopper to the surface through the passageway of the outlet.
