TPUよりも印刷しやすく、TPUより弾力性があり、TPUより柔らかい。バイクのエアクリーナージョイントをTPUで作ったらキャブを入れるのに苦労したが、PEBAで作り直したらとても作業性が良くなった。絶版ゴム系パーツのリプロに十分使えると思います。

TPUよりも格段に高反発で素晴らしいです。カラーバリエーションが増えると嬉しいです

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

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。 --- 追記:Sovol SV08で使用する際に設定した内容 ・ツールヘッドに直接引き込む ・エクストルーダーのギアは強めに噛ませる ・ノズル温度220℃以上 ・フロー上限2mm3/s

湿気に非常に弱いTPUフィラメントですが、この商品はしっかりとしたアルミ製の袋にはいっていて全く湿気を吸っていませんでした。 ドローン用の部品の印刷に使用しましたが、印刷時の失敗もなく、普段使っているTPUと同じ設定で印刷することができました。

コンパクトな箱入り真空パックで届きます。 普段は1kgのplaフィラメントを使っていますが、使用頻度の少ないtpuフィラメントはこれくらいがちょうど良いと思います。

I bought this to try making custom hard case inserts, similar to another reviewer. I was largely unsuccessful getting this to print at 270C on my 0.4mm nozzle (it immediately clogged), but after switching to 0.6mm I have had no issues at all. At the 270C settings, this material really can't do overhangs, but after doing some testing I found that it works fine at 15% infill with 4+ top layers. At lower infills or fewer top layers, the infill texture shows through and there can be gaps in the top layer. Because of the foaming aspect, prints seem to use less filament than if printed in regular TPU. The texture of the finished product is similar to EVA foam and looks very clean after cleaning up some errant strings. It is perfect for my use case, and it's so nice being able to print an exact fitting insert! In the past I used sheets of packing foam, and it always was a pain trying to cut an exact fit while maintaining a clean look. Since the surface comes out relatively smooth it's also easy to wipe clean. TLDR; this stuff is great!

Ho già il Filaflex 82A di Recreus, che la mia Qidi Q1 Pro gestisce senza difficoltà; dato che quello è un filamento di grande qualità ma anche costoso, ho voluto provare il Siraya Tech 85A per realizzare componenti più "economici", come ad esempio guarnizioni di grandi dimensioni. Con sorpresa devo dire che il materiale mi ha veramente sorpreso: ha una consistenza assolutamente inaspettata, molto simile a quella della gomma siliconica e quindi molto flessibile. 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.

This is the best material ever made! Can print faster than the normal TPU

Nice and string free TPU prints!! It is VERY firm! Too firm my what I bought it for, but I will find other uses!! I have tried 90A and 95A filaments and main issue was always the strings... This filament did not have one. I am VERY happy with it!!!

I got this stuff dialed in really quick. I had no idea what to expect or what settings to use because this was my first attempt with any flexible filament. In the end, I didn't use much from the generic TPU settings. My settings for this are closer ABS with 100% fan. Turn down the flow and turn up the pressure advance. Definitely give yourself some extra clearance if you do need supports. I'm using a PEI build plate and I definitely suggest the glue stick. I was worried about this stuff not coming up where the glue had run a little thin. I definitely have a few more settings to tweak but so far I've had great results. If I can keep from wasting all the stuff printing squishy benchies and more useful parts it will definitely be worth the price. It's almost like printing vulcanized rubber. The layer adhesion is amazing and if you print it right the impact resistance is impressive. I could not deform it at all with several blows from my 5 lb BFH. The part tested is one of the vibration feet pictured in the review.
