Vorher anständig getrocknet, im Slicer einfach 'Generic TPU' gewählt und ab dafür. Absolut glatter, gleichmäßiger Druck sogar auf der textured PEI platte.Das hatte ich mit viel komplizierter vorgestellt.Ganz toll (noch toller wäre es nur, wenn es das noch in anderen Farben als Schwarz und Transparent gäbe)! ### ⭐⭐⭐⭐⭐ S'imprime très bien sur une K1 MAX à 30mm/s *by on Reviewed in France 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 CompatibilitéLe 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 séchageUn 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.VerdictC'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 ! ### ⭐⭐⭐⭐⭐ Smooth TPU *by on Reviewed in Canada 3 June 2026* Best TPU hands down. Prints with excellent consistency and the feel of the finished prints is excellent. Recommend going a bithotter thanthe 230 on the roll, sticks well to a warm bed. 10/10 will buy again ## Frequently Bought Together - 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) - OVERTURE TPU Filament 1.75mm Flexible TPU Roll, 95A Soft 3D Printer Filament, 1kg Spool (2.2 lbs), Dimensional Accuracy +/- 0.02 mm (TPU Black) - OVERTURE PETG Filament 1.75mm, 3D Printer Filament, 1kg Filament (2.2lbs), Dimensional Accuracy Probability +/- 0.02 mm, Fit Most FDM Printers (Black (1-Pack)) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/659707364-flex-tpu-filament-85a-shore-iso-10993-high-flexibility-toughness](https://www.desertcart.co.za/products/659707364-flex-tpu-filament-85a-shore-iso-10993-high-flexibility-toughness) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-06-21*
