Flexible Vase



SainSmart TPU filament is featured by its high strength and flexibility, like a hybrid of plastic and rubber.

95A TPU has high abrasion resistance and low compression compared to rubber parts, especially at higher infill. 

 In comparison with most common filaments like PLA and ABS, TPU must be run much slower.

  • 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.
