Review: When it works it's excellent. I may have a bad roll. - EDIT: I'm updating to 5 stars. Customer service is top notch and very responsive. They provided me a new roll and I'm successfully printing now. I bought this TPU as I needed something softer than A95. Initially it printed great and I was able to print a couple of parts I needed on my K1 max. However, I think I got a roll that is spooled way too tight. As I started getting into the roll it became more difficult to print as it came off the spool. It would just stretch leaving extreme under-extrusion on the part. On one of my printers, CR6SE with LGX Lite, I went straight from a top mounted spool holder to the extruder to reduce the length and it still had issues pulling it off this spool. I may have just been given a bad roll but at this price I wont be buying more. Follow there instructions for best results. They have a guide on their web site.
Review: Realistic rubber feel - I like this filament, it produces a better rubber feel compared to 95A. I run it slow so large prints take a while, but its worth the wait. I make sure to dry it for 48 hours prior to printing, and print it at 240*C.

### ⭐⭐⭐⭐⭐ Best performing 85A TPU I've tried
*by J***Y on June 14, 2024*

I previously printed with Ninjaflex TPU, but at $90 a roll currently I knew I needed to try something different. There aren't many cheap options for 85A TPU in 1.75. I decided to try this in my Bambu Labs X1C. 95A is too plasticy for my application so I avoid it. At first it wasn't doing well, but I eventually found their suggested method on their website and now it prints much cleaner than Ninjaflex. I will say Ninjaflex had a more grippy softer rubber feel, but this one still does the job for me and the consistent print quality makes it worth it. When using an X1C you CANNOT use the AMS with TPU, it's just not stiff enough. I used to feed my Ninjaflex from a Sunlu dryer/storage unit. That was fine but it didn't cut it with the Siraya. As their instructions say: Feed from external spool holder (my Sunlu dryer/box with rolloers is fine) Do not use a PTFE tube Feed directly into the top of the X1C to the extruder - again no PTFE tube! I printed some small wedges that keep the back half of my top glass cracked about 1/4" and it allows me to keep the AMS on top as well.
