Review: Problemloser Druck mit Standard-Profil - Lässt sich wunderbar im Bambu H2S drucken. Vorher anständig getrocknet, im Slicer einfach 'Generic TPU' gewählt und ab dafür. Absolut glatter, gleichmäßiger Druck sogar auf der textured PEI platte. Das hatte ich mit viel komplizierter vorgestellt. Ganz toll (noch toller wäre es nur, wenn es das noch in anderen Farben als Schwarz und Transparent gäbe)!
Review: Good filament but... - The filament itself is great, but it was a terrible idea to put such a difficult to feed filament on a cardboard spool. My spool was very minorly damaged, so the filament wasn't feeding properly from my Creality Space Pi drier, so I had to reload it onto a spare plastic spool I had.

### ⭐⭐⭐⭐⭐ Problemloser Druck mit Standard-Profil
*by M***N on 29 January 2026*

Lässt sich wunderbar im Bambu H2S drucken. Vorher anständig getrocknet, im Slicer einfach 'Generic TPU' gewählt und ab dafür. Absolut glatter, gleichmäßiger Druck sogar auf der textured PEI platte.

### ⭐⭐⭐ Good filament but...
*by D***E on 22 June 2026*

The filament itself is great, but it was a terrible idea to put such a difficult to feed filament on a cardboard spool. My spool was very minorly damaged, so the filament wasn't feeding properly from my Creality Space Pi drier, so I had to reload it onto a spare plastic spool I had.

### ⭐⭐⭐⭐⭐ Very soft, won't print on just any machine but very nice filament!
*by D***E on 4 July 2026*

This is very soft TPU, ideal for stuff like rubber seals and rc car tyres. It is smooth and shiny and has an impressive amount of strength. It can be stretched quite a lot, you have to work quite hard to tear it so I feel that it could be a long lasting material for seals and tyres etc. A word of caution - this will not work in all machines. Its so soft that to get it to feed into the extruder I had to bypass the Bowden tube altogether as it creates too much friction. On my Creality K1 Max I can remove the top so I fed it directly into the extruder and left the top off of the machine. You then have to release the tension on the filament as it enters the extruder or it will crush the filament and jam up before it even enters. If you have anything other than a direct drive extruder forget it. You just can't push this stuff through Bowden tube it physically won't go. Dual extruder is a MASSIVE advantage. If you have the ability to extrude both this and PETG/PLA at the same time then youre laughing. Use the PETG/PLA for the support structure and print the object on top of that. Printing a support structure made of this TPU and then the model on top won't work, you won't get the two apart without a fight I promise you. All that aside it is really good filament so ill be ordering this again in the future.
