Abstract: An additive manufacturing system configured to a 3D print using a metal wire material includes a drive mechanism configured to feed the metal feedstock into an inlet tube and a liquefier. The liquefier has a chamber configured to accept the metal feedstock from the inlet tube. The metal feed stock is heated in the chamber such that a melt pool is formed in the chamber. The liquefier has an extrusion tube in fluid communication with the chamber, the extrusion tube having a length (L) and a diameter (D) wherein the ratio of length to diameter (L/D) ranges from about 4:1 to about 20:1. The system has a platen with a surface configured to accept melted material from the liquefier, wherein the platen and the liquefier move in at least three dimensions relative to each other. The system includes a regulated source of pressurized inert gas flowably coupled to the liquefier and configured to place a controlled positive pressure onto the melt pool sufficient to overcome the resistance of the extrusion tube such that a part may be formed by the extrusion of the liquidus metal along toolpaths defined by the relative motion of the liquefier and the platen.

Abstract: An additive manufacturing system includes a build chamber with at least first and second side walls and top and bottom walls. A central deformable, thermal insulator has a first edge and a second edge, where a print head carriage is movably retained within the central deformable thermal insulator and is configured to move print heads within a build plane of the build chamber under control of a gantry. The system includes first and second dynamic thermal barriers each having a length between a proximal edge and a distal edge wherein the proximal edge is configured to be secured to the central deformable insulator and a distal edge is configured to be movably retained to the build chamber such that as the print head carriage moves laterally across the build plane, each dynamic thermal barrier moves with the central deformable insulator and print head carriage, and retains its length.
