Original Abstract Submitted
methods for additive manufacturing of objects comprising a polymeric foam are disclosed and comprise extruding a mixture of a base polymer and a foaming agent that are provided in the form of at least one feedstock material, the mixture produced by admixing the base polymer and the foaming agent within a polymer processing space of an extruder by an independent mixing rotor, and further comprise sequentially depositing multiple layers of the mixture to form a three-dimensional object. heating of the mixture to cause activation of the foaming agent and formation of the polymeric foam may be done during the extrusion process or afterward by a separate heating step.
