Frequently Asked Questions
What makes TPU flexible and wear resistant?
Thermoplastic polyurethane chains give elastic recovery, abrasion resistance and tear strength, which is why it is used for cushions, seals and soft gripping surfaces.
How should I feed TPU on my printer?
It is compatible with mainstream FDM printers; a direct drive extruder with slow printing and minimal filament path clearance gives the steadiest results.
What temperature should I print at?
Recommended nozzle temperature is around 220C; keep speeds moderate and test a small piece first for your setup.
How much does one spool print?
Estimate by part weight against the one spool net; flexible parts are often solid, so weigh a sample part before planning volume runs.
Which colors does the rainbow TPU come in?
Current slot is a blue-purple rainbow gradient; effect transitions vary along the spool by design.
What parts is this TPU for?
Soft jaws, cushioning pads, dampers, gaskets, protective covers and flexible wheels for jigs and fixtures.
How do I store TPU spools?
TPU is moisture sensitive: keep vacuum sealed with desiccant, and after opening dry-store spools before printing for bubble-free extrusion.
