Abstract: A method of forming a three dimensional object comprising: moving a first polymer material (30) through a first feed channel (38) of an extrusion die (10) having multiple feed channels; moving a second material (40) through a second feed channel (38) of the extrusion die, wherein the second material comprises a solvent, a release agent, a coating or a second polymer material; forming a multilayered extrudate (20) along an extrusion axis, wherein the multilayered extrudate comprises the first polymer material (30) and the second material (40), and wherein the extrusion axis is parallel to the movement of the multilayered extrudate; depositing a multitude of layers of the multilayered extrudate in a preset pattern on a platform (2); and fusing the multitude of layers to form the three dimensional object. An article of manufacture comprising: a three dimensional object is also disclosed.

Abstract: A process for drying resinous materials, comprising: delivering, by way of a plurality of resin channels, resin fluid comprising polymer and solvent into at least first and second steam channels (101) having within a flow of steam, the first and second steam channels (101) each receiving resin fluid from a plurality of resin channels, the first and second steam channels each (101) being received by a stage 1 manifold (121), the steam and resin being delivered under conditions so as to separate at least some of the solvent from the resin fluid; and collecting at least some of the polymer from the resin fluid.
