Filament loading system in an extrusion apparatus |
摘要 |
An apparatus which extrudes flowable material from a liquifier includes a system for loading filament supplied in a cassette. The cassette is loaded into a loading bay of the apparatus. A strand of filament from the cassette is engaged and advanced along a path to the liquifier using a drive wheel or roller pair. A conduit having an entrance in the loading bay guides the filament as it is advanced. The filament loading system of the present invention provides a convenient manner of loading and unloading filament in a three-dimensional modeling machine, and can be implemented in a manner that protects the filament from environmental moisture.
