Creality-Capricorn tube is far superior to the white PTFE tubing supplied with most 3D printers. Its much smoother to feed filament through. And when printing it reduces the drag on the extruder giving a much smoother travel and print quality. High Lubricity Additives make our XS Series tubing the lowest friction Bowden tubing on the market. Less friction means more responsiveness, less retraction, more accurate prints, less slippage, wear, and tear on the extruder, and less clogging when printing chunky filaments such as some wood fills or iron fills. Lower retraction means time saved every time the extruder retracts. Over the course of a print, a few milliseconds here and a few there add up to a lot of time saved.
