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 (White, 1kg)

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 tubeFeed 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.

It’s hard to find a good TPU and even harder to find one less than 95a. This filament is extremely soft and prints so smooth. EDIT : directly adding the filament spool over head the nozzle and directing it right over the nozzle allows it to print smooth and without issues. See picture.

The material runs good and has great adhesion at the listed temps, but pulling it off the spool is tough as the spool is quite heavy to turn.Best prints were from coiling it up and letting it feed from a pile of filament

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.

Was told this filament didn't play nice with Bambu extruders, but decided to try it anyway as I wanted softer than 95. Dried it and tossed on the back spool holder of my P1S and sent a calibration cube. Expected issues, but instead it printed amazing. Next prints are 7+ hours each, but at least I have a little confidence they will be just fine.

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.

Printed with lots of TPU over the years and this stuff is very flexible and durable but completely water logged out of the bag. I shouldn’t need to dry new filament. Will be returning it’s unusable as shipped

Bon résultat, ni trop souple ni trop dur. Exactement ce que je recherchais. Adhérence très correcte et même parfois difficile à décoller.

Filament facile à imprimer ( pour du 85A)Excellente adhérence des couches.

Das Siraya Tech Flex TPU-Filament – 85A Shore kommt im typischen Filamentkarton beim Käufer an.Das Filament ist sauber aufgewickelt und mit Silicagelbeutel ordentlich eingeschweißt.Die Druckergebnisse sind auf meinem Drucker nicht zu beanstanden, alle Druckobjekte kommen sauber aus dem Drucker. Haftungsprobleme oder Stringing traten nicht auf.Preislich liegt das Filament ebenfalls im akzeptablen Bereich.5 Sterne.

フニフニと柔らかくペタペタした感触のフィラメントです。内径2mmのテフロンチューブに通すとそれなりの抵抗があるので、径の大きいチューブを使用するか押し出し速度を非常にゆっくりに設定して使用する必要があると思います。私は後者で使用しており、フローの上限を2mm^3/sにして良好な品質でプリントできています。

The best tpu you can buy, prints extremely well.
