Siraya Tech Flex TPU Filament - 85A Shore, ISO 10993, High Flexibility & Toughness, High Flow & Speed, Easy to Print, Moisture-Resistant Aluminum Bag - Ideal for Footwear, Protective Gear (Black, 1kg)

I've been printing professionally for over 10 years, and this filament is one of very few things I call a game changer. I just met my first print at 250°c 72% flow and it printed great but more importantly the consistency of it is completely novel and I already have a practical use for it. Kinda like spray foam after it has set up but not fully hardened. I now have a print going at 270°c 54% flow and it is printing flawlessly.Expensive for sure, but at 54% flow rate I basically have about 1.5 kg equivalent of output. Extremely unique and useful output at that.

I’m pretty new to 3D printing and had great results with this filament. I dried it for over 12 hours in an AMS HT with the recommended temp from Siraya. I used their print profile available on their website for my X1C. The profile was for a .4 nozzle and I have a .6 installed so I wasn’t sure how it would work but was pleasantly surprised at how good it was. I don’t know if it was Bambu or me trying to create a new filament that adjusted the max volumetric flow but it printed great at 3.2mm3/s. I tried a benchy at 4.5 later and it printed great as well so I think it could still go higher, I just haven’t tested it. Would absolutely buy this again.

Just used it to print some shoes, the material is awesome! Very comfy for this shoe design, gets close in softness to Ninjaflex and it's cheaper so, I'll look forward into using more of these material for other shoes :)

Most TPU filament is shore 95A. I was looking for something softer and decided to give this a shot. My initial impression didn't start off well as the cardboard spool it came on was really beat up. I run TPU out of a Sunlu dryer which has rollers. So when the spool is almost a square, it's less than ideal, especially with stretchy TPU. The box wasn't damaged, so the beat up spool is an issue with their manufacturing facility, not shipping.I didn't have very high hopes after seeing the spool. Boy, was I wrong. This stuff prints amazingly well. I ran a Benchy on my Bambu Lab X1 Carbon. It looked amazing. The 95A TPU I was previously using looks good, but this stuff is another level, which is surprising since it should be harder to printer being more flexible. The Benchy with this TPU rivals the quality of a PLA print. It is nearly flawless. It looks gorgeous. And it's considerably more flexible than 95A TPU.I'm not easily impressed and this stuff blew my socks off.EDIT: I had several print failures but it was due to the really bad cardboard spool. I had to respool it onto a Bambu Labs plastic spool. I wonder how many people that are saying they are having printing issues with this are running into this issue where the wonky carboard spool either doesn't rotate well or the filament gets stuck between the side of the spool.

Great filament .. soft and was easy to print and shipped quickly, will buy again if I have a chance product was neat , no clogs ,easy to print tpu temperature ,was dry upon opening, and great transparent color.Filament diameter was consistent and properspool was clean

echoing the other review, this stuff is pretty neat, and so consistent in its extrusion. the profiles siraya built for this are also excellent, the lack of stringing on a foamy filament like this is remarkable. and being able to print a 75a shore hardness on a standard extruder is also pretty mind blowing. no more fiddling with idler tension and building in zero friction filament paths!

My favorite TPU!I love how you can adjust the durometer to get it where you want.Download their print profiles off their website. Works fine on Bambu P1sSeems to be easier to print than Bambu 85A TPU as well

This broke my bambu p1s and a1, it stuck on the inside of the extruder and nozzle making the machine think theres still filament loaded. Dont buy this
