Abstract

Additive manufacturing system, which may include a nozzle (51) having an inlet for receiving a flowable material (53) and an outlet for depositing the flowable material (53). An applicator head (43) may surround at least a portion of a proximal region of the nozzle (51). The applicator head (43) may include a housing (46), a cooling inlet for receiving a coolant into the housing (46), a cooling outlet configured to allow the coolant to exit the housing (46), and an air inlet. A roller (59) may be mounted on the applicator head (43) to one side of the outlet of the nozzle (51). The roller (59) may include an air outlet, wherein a flow path connects the air inlet and the air outlet so that air enters the air inlet and exits the air outlet. The roller (59) may also include a plurality of holes (70) located on an external surface of the roller (59).

Abstract

Embodiments of the present disclosure are drawn to additive manufacturing apparatus and methods. An exemplary additive manufacturing method may include forming a part using additive manufacturing. The method may also include bringing the part to a first temperature, measuring the part along at least three axes at the first temperature, bringing the part to a second temperature, different than the first temperature, and measuring the part along the at least three axes at the second temperature. The method may further include comparing the size of the part at the first and second temperatures to calculate a coefficient of thermal expansion, generating a tool path that compensates for the coefficient of thermal expansion, bringing the part to the first temperature, and trimming the part while the part is at the first temperature using the tool path.

Abstract

Embodiments of the present disclosure are drawn to additive manufacturing apparatus and methods. An exemplary apparatus for fabricating components via additive manufacturing may include a programmable CNC machine. The CNC machine may comprise a first worktable extending in a first plane and a second worktable extending in a second plane, wherein the second plane is oriented at an angle relative to the first plane. At least one conveyor belt may be operably coupled to the first worktable. A printing gantry may be displaceable along a first axis of the CNC machine. The CNC machine may also comprise an applicator having a nozzle configured to deposit material on the second worktable.

Abstract

An additive manufacturing method for delivering a flowable material from a nozzle of a programmable computer numeric control (CNC) machine, the nozzle being configured to translate along a first axis, a second axis perpendicular to the first axis, and a third axis orthogonal to the first and second axes. In one embodiment, the method includes actuating an extruder to form a flowable material, delivering the flowable material to a pump, sensing a pressure of the flowable material, and adjusting at least one of a speed of the extruder and a speed of the pump based on at least one of the sensed pressure and a rate of translation of the nozzle along one or more of the first, second, and third axes.
