Review on 🔧 Yousu Performance Flexible Filament: Compatible Additive Manufacturing Products for Enhanced Flexibility by Chris Bowden

Let me just say this is one of the easiest to set up/adjust TPUs I've worked with. Well packaged with a good vacuum seal so you know you are getting a fresh spool unlike some others that come with broken seals. This is necessary for TPU because it is very hydrophobic. In addition, the bag is zipped (Ziploc) for long-term storage. The spool is crystal clear and graduated so not only can you see how much you have left, it's marked in 10 percent increments. The filament is neatly wound, expect a tangle-free print. It's nice that they added an extra MK8 M6 .4 attachment so you can start over if you want. These are the little additions that make the company stand out. This is 95A Shore flexible filament. So don't expect it to be very soft like some of the more difficult to print and more expensive 75A Flex filaments. However, it's more than flexible enough that it can have a wide range of customization by changing the amount of fill. An excellent choice when you need flexibility while retaining some structural features. Good for things like phone cases or anti-vibration feet, but just as good for display models due to its ability to reproduce fine detail. The quality turned out to be better than I expected and required minimal adjustments to get a great print. With the settings chosen, it prints almost as easily as PLA! Brilliant rich red, prints well at 220°C and 60 degrees bed temperature on my Ender 3 V2 (stock extruder with glass bed Bowden tube). I used blue painter's tape to limit the bed's adhesion to the treated glass, but a glue stick would also help. Very good layer-to-layer adhesion, making it sufficiently strong and tear-resistant. Minimal tipping tension, especially for TPU (setting the right temperatures and pressure is slow with little or no retraction), no problems with under-extrusion, over-extrusion, clogging or jamming. Several lengths randomly sized tested and all was within spec. All three prints shown were printed with a layer height of 0.2. Two of these were designed as stress tests, so these aren't the easiest of prints. Overall I am very impressed with this thread, excellent value for money. Looks like I've found my new favorite TPU school!
