  • Publication number: 20220072764
    Abstract: A drawn fused filament fabrication method of three-dimensional printing is disclosed in which the filament extruded is variable and not restricted to the diameter of the nozzle used for extrusion. This method composes three steps. The first is to extrude a small amount of material at a starting position. Next, the extruding head pulls the extruded material along while moving away from the starting position. During this time to material cools down and solidifies. As a result, a thin filament is formed. Third, once the extruding head moves to a destination, a small amount of material can be extruded and deposited to anchor this newly formed filament to a surface. The drawn fused filament fabrication method may be used to print three-dimensional parts having significant lower thickness than the diameter of the nozzle used to extrude the printing material.
