Abstract: An additive manufacturing system for producing a structure includes a base assembly, an elongated member, a carriage, and a first member. The elongated member is fixedly coupled with the base assembly and extends upwards from the base assembly. The carriage is rotatably coupled with the elongated member and configured to translate upwards along the elongated member. The first member is fixedly coupled with and extends outwards from the carriage. The first member includes a material dispensing device configured to dispense material as the carriage rotates relative to the elongated member.

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.

Abstract: A retrofitted pipe conduit addition method and assembly includes a pipe having a cylindrical shape and which has an outer diameter. A coupler is positioned on the pipe. A cylinder is integrally coupled to and extends away from the coupler. The coupler has an aperture extending therethrough. The cylinder bounds the aperture. The pipe has an opening extending therethrough and the cylinder is aligned with the opening. The cylinder may then be fluidly coupled to a drainage conduit.
