flexy2 ™ TPU Printing Guidelines
With a Shore Hardness of 98A you can influence how flexible a print should feel by adjusting infill and shell settings.
- Extruder temperature: 200 – 230 °C Please see our TPU trouble shooting guide on our website if you experience excessive oozing, stringing or other issues
- Retraction: Adjust your settings, too little retraction and you will have strings, too much and you will get blobs of filament when the print head starts its next segment of printing
- Platform temperature: Room temperature
- Print Speed: 10-30 mm/s. Due to the nature of flexible filament and the potential to buckle when being pushed through the hot end, it is highly recommended that you print at slow speeds. If you are still having difficulty consider printing yourself a filament guide as a modification to your printer. You can find printer mods on Thingiverse (see my collection and/or search with your printer name)
|At 230c I turned off retraction and ran the fan off for the first layer and ramped up to full during the next 5 layers (Cura stock setting) Bed was @ 70c with no adhesion issues. I ran at 35mm/sec and at .2mm layer heights for the flex box from thingiverse (thing:1695910)
It printed great with my regular TPU settings. 195C 45mm/s with Flexion extruder
|You have to print at 225c and at 10mm/s for good transparent prints. I used Vase mode.
* NOTE* some colors are not transparent (black,white). Indicated on label.
