DESCRIPTION


Thermoplastic polyurethane (TPU) is a high strength flexible filament. TPU is essentially polyurethane, it belongs to the TPE class of thermoplastics (similar to the stuff NinjaFlex is made of).
In addition to being stronger compared to other flexible materials on the market, we found TPU to be easier to print with, with great layer to layer bonding. Let's make our ideas actual!

 

SPECIFICATION
  • Material : Rep-Flex TPU - Vacuumed Sealed with desiccant
  • shore hardness: 95A
  • Weight: 250g
  • Diameter: 1.75mm (+/- 0.05mm)
  • Roundness: 1.75mm (+/- 0.03mm)
  • Recommended extruder temperature:195 - 230°C

PRINTING TIPS
  • Recommended for printers with direct drive extruder, 0.4~0.8mm Nozzles.
  • With bowden extruder you might pay more attention to these tips:
  1.  Print slow 15-30 mm/s Printing speed
  2.  First layer settings. (Height 100% Width 150% speed 50% e.g.)
  3.  Retraction disabled. This would reduce messy, stringing or oozing printing result.
  4.  Increase Multiplier(Optional). set to 1.1 would help the filament bond well.
  5.  Cooling fan on after first layer.

    Great filament and cool colors.

    This tpu filament is great, just this product where there are 5 spools of 250g might not be the cheapest per kilogram but I wanted different colors so this was perfect for my application. The filament is easy to print and looks amazing. I was able to print this filament at 30mm/s with a bowden setup. I might go faster but I haven't tried it yet. Can't complain about anything.
