Filament spool

A container comprising a housing that is configured to rotatably mount a filament supply spool, and a filament guide mechanism mountable within a channel of the housing, where the filament guide mechanism comprises a filament pathway configured to guide the filament from the filament supply spool rotatably mounted in the interior chamber, and a sensor configured to detect the presence of the filament through at least a portion of the filament pathway.

Filament container and methods of use thereof

A filament spool for use in a filament spool container, where the filament spool comprises a first rim and a second rim offset by an axial shaft, and a series of grooves extending along a first portion of the first rim and configured to receive a filament of a material while the filament is wound around the axial shaft in a first rotational direction.

Filament guide mechanism for filament spool container

A tip cleaning assembly for use with an extrusion head of an extrusion-based layered deposition system, the tip cleaning assembly comprising a support component, a purge ledge assembly mounted on the support component, at least one set block mounted on the support component adjacent the purge ledge assembly, and at least one contact head removably mounted on the first set block, where the at least one contact head is configured to engage at least one extrusion tip of the extrusion head.

Extrusion tip cleaning assembly

The present invention is a method and apparatus for building three-dimensional models by deposition modeling techniques from moisture-sensitive thermoplastics. A feedstock of thermoplastic modeling material is dried to a low moisture content and supplied to a dispensing head of a modeling apparatus. The dry thermoplastic material is heated in a liquifier and deposited in a predetermined pattern so as to build a three-dimensional model.
