## Description

Introducing the Siraya Tech Flex TPU Black/White 3D Printer Filament – a breakthrough in 3D printing technology. With its 85A Shore hardness, this premium filament is tailored for a wide range of printing needs, from professional to hobbyist uses. Why Choose Siraya Tech Flex TPU 3D Printer Filament? Exceptional Flexibility and Strength: Our Flex TPU 85A filament combines rubber-like elasticity with thermoplastic durability, perfect for versatile projects. And is significantly softer than commonly available 95A TPU. User-Friendly Printing: Designed for hassle-free printing, our 3d printer filament 1.75mm ensures an uninterrupted, smooth printing experience. Advanced Moisture Protection: Thanks to its aluminum packaging, our filament stays protected from moisture and external factors, preserving its quality for longer. Wide-Ranging Utility: Whether it's custom footwear, protective phone cases, or medical devices, the Flex TPU 85A is your filament of choice. Safety First: Prioritizing your health, our biocompatible filament is suitable for sensitive applications like medical device manufacturing.

Review: Good filament but... - The filament itself is great, but it was a terrible idea to put such a difficult to feed filament on a cardboard spool. My spool was very minorly damaged, so the filament wasn't feeding properly from my Creality Space Pi drier, so I had to reload it onto a spare plastic spool I had.
Review: Very soft, won't print on just any machine but very nice filament! - This is very soft TPU, ideal for stuff like rubber seals and rc car tyres. It is smooth and shiny and has an impressive amount of strength. It can be stretched quite a lot, you have to work quite hard to tear it so I feel that it could be a long lasting material for seals and tyres etc. A word of caution - this will not work in all machines. Its so soft that to get it to feed into the extruder I had to bypass the Bowden tube altogether as it creates too much friction. On my Creality K1 Max I can remove the top so I fed it directly into the extruder and left the top off of the machine. You then have to release the tension on the filament as it enters the extruder or it will crush the filament and jam up before it even enters. If you have anything other than a direct drive extruder forget it. You just can't push this stuff through Bowden tube it physically won't go. Dual extruder is a MASSIVE advantage. If you have the ability to extrude both this and PETG/PLA at the same time then youre laughing. Use the PETG/PLA for the support structure and print the object on top of that. Printing a support structure made of this TPU and then the model on top won't work, you won't get the two apart without a fight I promise you. All that aside it is really good filament so ill be ordering this again in the future.

### ⭐⭐⭐⭐⭐ S'imprime très bien sur une K1 MAX à 30mm/s
*by L***Y on 10 October 2025*

Siraya Tech Flex TPU 85A : Un TPU 85A exceptionnel ! Je suis extrêmement satisfait de ce filament Siraya Tech Flex TPU 85A. C'est un excellent choix pour quiconque cherche un matériau à la fois souple et résistant. Qualité d'impression et Compatibilité Le niveau de flexibilité (dureté 85A) est parfait pour des pièces nécessitant une bonne élasticité sans être trop "mou" à l'impression. J'ai obtenu de très bons résultats en l'utilisant sur mon imprimante Creality K1 Max. Il s'imprime étonnamment bien, même à une vitesse de 30 mm/s pour le remplissage, avec une adhérence entre les couches remarquable et des impressions propres et fiables. C'est un excellent point pour un filament flexible ! Conseil d'utilisation : L'importance du séchage Un point crucial à noter pour réussir vos impressions : ce TPU, comme beaucoup de flexibles, est très sensible à l'humidité. Il est impératif de s'assurer que le filament est parfaitement sec avant et pendant l'utilisation. J'ai dû le passer au sèche-filament pour obtenir des performances optimales. Si le filament n'est pas sec, vous risquez d'avoir des bulles, des défauts de surface et une mauvaise extrusion. Une fois sec, il s'imprime à merveille. Verdict C'est un TPU que je recommande vivement, en particulier aux utilisateurs d'imprimantes rapides comme la K1 Max, à condition de faire très attention à son séchage. La qualité Siraya Tech est au rendez-vous. C'est un excellent rapport qualité-prix pour des pièces techniques ou des prototypes souples !
