Abstract: A consumable assembly for supplying filament to a 3D printer includes a spool-less filament coil, a payout tube, and a compressive band. The coil of filament is wound in a configuration having a generally cylindrical outer perimeter and an open interior; the coil has a payout hole extending from an inner layer of the coil to an outer layer of the coil and includes a filament strand configured to be withdrawn through the payout hole in response to a pull force, to thereby withdraw filament from the interior of the coil. The payout tube is disposed in the payout hole and provides a filament port. A compressive band is disposed over the outer layer and is configured to exert a compressive radial force on the coil so that the coil maintains its cylindrical shape without deformation, and the filament strand may be drawn through the filament outlet free of kinks, twists or tangles.
