### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    TPU is great material for printing
  

*by K***D on Reviewed in the United Kingdom on 12 September 2016*

Great TPU material from Sainsmart. Used to order direct from China,  but shipping times are a pain. Ability to get from Amazon at roughly the same price is a great result.TPU prints out at 215 deg on a 70 deg bed, no stringing and great quality prints.Highly recommend this material for home printing in flexible materials.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fantastic
  

*by D***N on Reviewed in the United Kingdom on 14 May 2017*

Printed really well straight away. Using a Prusa i3 with Bowden-type (short, though) extruder. Slow speed is needed, 25mm/s max.No idea why other TPU-based filament costs like 40 quid but this doesn't.
