1. A method, comprising:
directing, by an internal contact heating device and an external heating device, a patterned heat energy onto a printer bed of a printer chamber and supported manufacturing materials supported by the printer bed,
wherein the printer chamber has 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,
wherein the internal contact heating device is built into the printer chamber, and
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.
