    Abstract: A 3D printer includes a chamber configured to receive extruded material to print a part and a tool chamber above the chamber, the tool chamber comprising a viewing window and a tool rack. The 3D printer includes a plurality of print heads, each of the plurality of print heads residing in a docked position on the tool rack and when not in use. Each of the plurality of print heads comprising a illuminated status indicator configured to emit a plurality of signals indicative of a status or error of the print head or a status of the 3D printer, wherein the illuminated status indicator faces the viewing window and a plurality of sensors located on the print head or in the 3D printer and configured to detect a status of the print head or other printer components or an error in the print head or other printer components.

    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.

    Abstract: An extrusion-based 3D printer configured to print 3D parts in a layer-by-layer manner includes a platen configured to accept and support extruded material, at least one print head configured to extrude material to print a 3D part and a gantry configured to move the at least one print head as the material is extruded. The 3D printer includes at least one head carriage configured to engage the at least one print head. The at least one carriage is configured to engage and retain the at least one print head, where a filament cutter positioned above the at least one print head. The filament cutter includes a blade configured to be moved by the user, such that the blade is positionable between a non-cutting position where filament can be fed to the at least one print head and a cutting position wherein the filament is cut above the print head.
