Yousu Red TPU is relatively new on the Amazon USA storefront. Their USA TPU inventory typically includes Red, White and Black 1kg rolls. Positive experiences with Yousu’s PLA, Silk Pearlescent PLA (gold) and Yousu Iform liquid Resin grey, encouraged me to retry printing with TPU.
3D printing with TPU is more difficult that printing with common PLA, which most hobbyists start out with. Slower print speeds, hotter print beds, various hotend temperatures, minimal retractions and filament moisture must all be considered when setting up a slicer profile.
Direct Drive extruder setups are preferred when printing TPU. However machines with Bowden setups can be used, if the print speed and retractions are turned down significantly.
Personally I have only tried one other roll of TPU, since starting my 3D printing hobby. Those prints were successful, yet simple key chains. While printing Yousu’s Red TPU I challenged myself to make more complex items. Additionally I used the new-to-me Biqu BX printer with their dual geared H2 direct drive hotend setup.
As 3D printing continues to evolve, it's no surprise that the prices of filaments will also continue to fluctuate daily. But don't let this discourage you from pursuing your passion for 3D modelling!

Packaging
Filament rolls are often shipped in blank and unsecured cartons with basic black spools. Yousu continues to provide professional looking packaging, spool winding and sealing. The various types of filaments are contained in a custom printed box with easy to read labels that perform double duty to seal the boxes shut. Personally I have received several rolls intact, when the box was shipped by itself without an outer container. Yousu’s filaments are wound around a (wide – 75mm) clear plastic spool.
These spools use clear labels in four languages that include: percentage available marks, material type, diameter, temperature ranges and multiple social media addresses. Filaments are neatly wrapped around the spool, packaged with a desiccant pack and tightly vacuumed in an oversized resealable bag. Save that bag for storage and enjoy the smooth unwinding of your new roll. Random filament boxes from Yousu might be packaged with a free 0.4 MK8 nozzle and/or a 0.4 cleaning needle. May the odds be in your favor!

- Great Packaging
-
- Better than this picture implies
-
- TPU Flexible
- 95A Shore Hardness Flexible Filament Enables you print shoe insole, phone case, sporting goods, medical devices, automotive instrument panels
- Strong layer bonding like injection parts Unique recipe enables the printing parts function similar like TPU injection parts.
- Good compatibility Suitable for many existing 3d printer in the market. Such as Raise 3D, Makerbot Replicator 2 & 2x, Flashforge creator pro, Monoprice MakerSelect, Prusa i3, iDo, Troxy, Wanhao Before purchase, it is better to consult with your 3d printer supplier whether the printer can print flexible 3d filament.
- No warping & Precision Diameter Excellent first layer adhesion to reduce warpage, shrinkage, curl and print failure. Good diameter control.
Slicer Setup
Setting up a newly released printer to use Yousu Red TPU was not difficult, but it did require some trial and error. Biqu’s BX is the first printer I own that has both a direct drive and dual gear extrusion setup. Since the BX was brand new from its Kickstarter campaign, built in profiles did not exist yet for Cura. After setting up the basic machine size and extruder information, tweaking of temperature, speed and retraction settings were required to minimize stringing and surface defects. Yousu TPU stuck to the print surface and had great layer adhesion for the entire suggested temperature range. Speed and layer height did not affect the print quality any differently than it would for PLA.
Adjustments to retraction length affected the amount and thickness of stringing the most. Mistakenly I tried retractions all the way upto 2mm, which did in fact cause jams on my Biqu BX. Apparently direct drive setups should have retractions between zero and 1mm. Using lower retractions did help help reduce stringing. Printing with TPU, much like PETG, can be frustrating. Various tips are available in regards to temperatures and retraction settings. Using someone else’s profile will get your started towards tuning for your own machine. Realistically though, each machine’s profile still needs to be setup and tuned.
Conclusion
If you are in the market for some flexible filament or just want to experiment, Yousu TPU is a good brand to use. Bed adhesion was excellent using the entire suggested temperature range. Layer adhesion was strong while testing multiple layer heights. Yousu’s Red is vibrant and matches their PLA filament. Once you dial in your slicer profile, Yousu RED TPU will be a pleasure to print with. Just be sure to keep your filament dry!
