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.

Abstract: A consumable assembly for a 3D printer includes a spool carrying wound filament. The spool is configured to be installed into a spool cabinet to maintain the filament in a controlled environment. A filament key fob that carries a spool chip programmed with identification data for the consumable assembly is tethered to the spool. The filament key fob is configured to be received in a dock of the 3D printer outside of a controlled environment of a chamber of the spool cabinet while remaining tethered to the spool installed in the chamber of the spool cabinet.

Abstract: A consumable assembly for a 3D printer includes a spool carrying wound filament. A 3D printer includes a print head configured to receive filament material and a spool cabinet configured to have a filament spool positioned therein to provide a controlled environment for filament on the filament spool. A dock of the 3D printer is located outside of a chamber of the spool cabinet and is configured to receive a filament key fob, including a spool chip, of the filament spool to maintain the spool chip outside of the controlled environment of the chamber.

Abstract: A low pull force system for feeding a filament along a feed path from a source to a liquefier in a 3D printer includes a low compressive force loading drive for advancing filament from the source, a feed drive for advancing filament into the liquefier, and an in-line accumulator comprising a telescoping joint positioned in the feed path between the loading drive and the feed drive. When the telescoping joint is in a contracted position, the loading drive activates to feed filament into the feed path at a rate faster than a rate at which the feed drive advances filament into the liquefier, causing the telescoping joint to expand and accrue a slack of filament in the feed path. When the telescoping joint reaches an extended position, the loading drive deactivates while the feed drive continues to advance filament into the liquefier, and the slack of filament is consumed.
