Abstract: A 3D printer includes an enclosed build chamber thermally separated from a tool chamber. An upward-facing tool tray coupled to or integral with a carriage has an open bottom providing a tool port for accessing the heated build chamber. A thermal barrier is mounted in the tool tray, covering the tool port but penetrable through an aperture thereof. The aperture provides an entry point to the build chamber for a working end of an active print head, wherein when the working end is positioned though the aperture, the tool port is substantially closed.
