Anzi, la morbidezza del materiale mi è parsa maggiore di quella del Filaflex, nonostante secondo le specifiche tecniche non dovrebbe essere così.Aggiungo altre due proprietà molto interessanti del materiale: se stampato su piano liscio, ha notevoli proprietà antiscivolo anche su superfici bagnate (è ottimo per suole o inserti anti-slittamento); se stampato su piano liscio e in lastra sottile aderisce a vetri ed altre superfici lisce (come il metallo lucido) rimanendo appeso anche in verticale.La stampa è agevolata dal fatto che il produttore consente di scarica dal proprio sito web i profili di stampa già pronti per diverse stampanti 3D: quello della Q1 Pro non era presente, ma ho scaricato quelli per Bambulab e Flashforge, adattandoli senza problemi.Il risultato sono state stampe perfette sin dal primo utilizzo e con una resa di inaspettata alta qualità, anche con ugello da 0.4 mm.Il filamento è estremamente igroscopico e se resta esposto anche per poche ore le stampe falliscono. Va asciugato molto bene e possibilmente anche protetto durante le stampe prolungate.Per ridurre il rischio di stampe problematiche è consigliabile utilizzare ugelli più ampi di quello standard, come ad esempio da 0.6 o 0.8 mm.Allego un brevissimo video che mostra una serie di guarnizioni che ho disegnato e stampato, con ugello da 0.8 mm, per l'utilizzo in esterno.Pur con le avvertenze relative all'igroscopicità, il filamento rimane molto convincente per le eccellenti proprietà fisiche. ### ⭐⭐⭐⭐⭐ やわらかい *by on Reviewed in Japan 25 November 2024* RCプレーンのエアレスタイヤ製作用に購入95AのTPUは硬くて弾むので85Aを試してみました駐機中に変形しない強度と適度な柔らかさが両立出来ました95A用の設定で問題なしでした ## 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 (White, 1kg) - ELEGOO PLA Filament 1.75mm Red 1KG, 3D Filament Dimensional Accuracy +/- 0.02mm, 1kg Cardboard Spool(2.2lbs) 3D Printing Filament Fits for Most FDM 3D Printers - eSUN PLA+ Filament 1.75mm, Enhanced Toughness 3D Printer Filament PLA Plus, Dimensional Accuracy +/- 0.03mm, 1KG Spool (2.2 LBS) 3D Printing Filament for 3D Printers, Magenta --- ## 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.pe/products/605438456-flex-tpu-85a-3d-printer-filament-iso-10993-tested-white](https://www.desertcart.pe/products/605438456-flex-tpu-85a-3d-printer-filament-iso-10993-tested-white) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-08-17*
