Abstract
An automated filament exchange method includes: locating the spool for winding the first filament for the 3D printer; winding the first filament on the subspace of the spool located at the spool location step; allowing the first filament wound at the subspace first filament winding step to pass through a gap formed on the main space flange located between the main space and the subspace; and winding the first filament located at the main space of the spool on the main space of the spool, wherein after the first filament is wound on the subspace of the spool, the first filament passes through the gap and is then wound multi-layeredly on the main space of the spool.
