    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: 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.

    Abstract: A method of loading filament into a 3D printer that build parts by fused deposition modeling processes includes providing a 3D printer having a receptacle configured for accepting a plug-in connector from a filament supply. The method further includes providing a filament supply having a container configured to retain a supply of a filament, a filament guide tube having a length, an inlet end attached to the container and an outlet end, and a connector at the outlet end of the filament guide tube. The connector has a geometry allowing it to be plugged into the receptacle and comprises a conduit having an entrance for accepting the outlet end of the filament guide tube and an exit for passing the filament into the printer. The method includes causing a signal to be emitted proximate the receptacle such that when the plug-in connector is inserted into the receptable, light shines through the connector to inform the operator of a filament loading status.

    Abstract: A platen assembly for use with an extrusion-based 3D printer includes a grid assembly comprising at least a 4×2 framework of interlocked perpendicular x direction beams and y direction beams, providing a substantially planar upper surface and a bottom surface. The platen assembly includes a platen comprising a thin metal sheet supported on the upper surface of the grid assembly and secured to the grid assembly such that the top surface provides a substantially flat build surface. The x direction beams, the y direction beams and the platen are constructed of substantially a same thermal expansion properties, and wherein the build surface of the platen has a build surface area of at least 400 square inches and maintains its flatness to within a flatness tolerance of 0.020 inches over a temperature range of at least 20 C-300 C.
