Abstract

Additive manufacturing of a pipe is disclosed. A lowering mechanism is configured to be coupled with respect to a platform and to lower a pipe through an opening in the platform. An extrusion head is configured to receive material and selectively extrude the material via a nozzle. A gantry is coupled to the extrusion head and is configured to move the extrusion head to an identified location. A controller is coupled to the gantry and configured to direct the gantry to move the extrusion head based on pipe data that identifies a geometry of the pipe. A stabilizer mechanism is configured to maintain the pipe in a desired position during the extrusion of the material.
