Notes:
Pulling Friction is calculated as the average force required to pull 1.2 meters of 1.75mm PLA filament through 1 meter of tubing at a constant speed, relative to 1 meter of cheap white reference tubing. Note that although the friction of the TL series is about the same or even slightly lower than the XS series, it also has a larger internal diameter, making it less suitable for flexible filament and low retraction prints.
Stffness: Other Bowden tubes may vary significantly in stiffness, depending on the material from which theyre made. This tubing generally tends to be more flexible than most, with the TL being more flexible than XS.
Youngs Modulus (YM) is the measure of elasticity of the material. The XS Series additives give the PTFE a slightly greater YM than the TL Series.
Temperatures were approximated by heating samples of all tubing simultaneously, observing how quickly each one began to deform. Printer failures may happen at significantly lower temperatures.
Warning! Printing high temperature materials may create dangerous off-gassing.
