1. A machine for producing an additive printed part, the machine having a print head, wherein the print head is attached to a gantry, comprising:
a frame having a plurality of side walls that define an interior space;
a build table positioned within the interior space and including a print bed, the additive printed part being positioned on the print bed as the additive printed part is created;
a plurality of bellows attached at a first end to the gantry and at a second end to at least one of the plurality of side walls;
at least one window attached to at least one of the side walls;
a build volume defined by the plurality of side walls, the plurality of bellows, the build table, and the at least one window;
a first infrared heater disposed on the build table for heating the additive printed part being positioned on the print bed of the build table; and
at least one sensor positioned within the build volume for measuring infrared (IR) heat reflected by the additive printed part,
wherein each of the plurality of side walls, the plurality of bellows, and the at least one window includes a reflective surface oriented inward to the interior space.
