1. A manufacturing system, comprising:
a printer chamber having a printer bed that supports manufacturing materials, the printer chamber having an inner wall and an outer wall surrounding the inner wall with a layer of insulation sandwiched between the inner wall and the outer wall;
an internal contact heating device built into the printer chamber and configured to direct a patterned heat energy onto the printer bed and the supported manufacturing materials; and
an external heating device for the printer chamber and configured to direct the patterned heat energy onto the printer bed and the supported manufacturing materials,
wherein the internal contact heating device comprises:
a heating element embedded within the inner wall of the printer chamber that radiates the patterned heat energy into the printer chamber; and
a cooling element embedded within the outer wall of the printer chamber that cools the outer wall of the printer chamber, the cooling element being isolated from the heater element by the layer of insulation sandwiched between the inner wall and the outer wall printer chamber.
