We introduce a technique for 3D printing soft strands, fibers, and bristles using conventional 3D printers. Our work was inspired by the phenomenon that occurs during the operation of a handheld glue gun: when a person extrudes hot glue material and moves the gun away, a “string” of residue often forms unintentionally. The shape, length, and thickness of the resulting stringy material varies based on how much glue was extruded and how fast the user moves away from the extrusion point. This artifact often annoys users, but in this work, we exploit the phenomenon.
