    Abstract: A filament cassette and a filament loading assembly supply modeling filament to a liquifier in a three-dimensional deposition modeling machine. Two or more cassettes containing spooled filament are inserted into the machine. A strand of filament from a first one of the cassettes is fed to the liquifier for extrusion. Without operator intervention, the filament strand from the first cassette is withdrawn from the liquifier, and a filament strand from a second one of the cassettes is fed to the liquifier. The switching of filament feed sources is triggered by an event, such as an identification that the filament from the first cassette has reached a predetermined minimum length. In this manner, a used primary filament cassette is automatically replaced with a standby filament cassette, so that the machine need not experience downtime waiting for an operator to change the cassettes.

    Abstract: Disclosed are a filament cassette and a filament loading assembly for supplying filament in a three-dimensional deposition modeling machine. The filament cassette contains a rotatable spool of filament, and has an exit orifice through which a filament strand may exit the cassette. The filament loading assembly is mounted on the modeling machine and receives the filament cassette. The filament loading assembly has conduit for receiving a strand of filament from the cassette and a drive means for advancing the filament strand through the conduit. The filament cassette and loading assembly of the present invention provide a convenient manner of loading and unloading filament from the modeling machine. The filament cassette and the conduit may be made airtight so that the filament is protected from moisture in the environment.
