Review: 寸法精度が良くて扱いやすいエンプラとして使ってみました。 Bambu P1Sでプリントしました。Siraya Techに印刷プロファイルがあるのでそれをすこし変更して使いました。SuperTackのプレート温度が35度でしたが65度に変更しました。 Smooth PEIは使わないほうが良いです。定着が良すぎてプレートを壊してしまいました。SuperTack推奨です。ベッド温度が低くできて白化しにくくなります。 他のエンプラと違って湿気にも強くリーズナブルでとても良い。 ー追記ー Smooth PEIですがのり（ケープ3Dエクストラキープ）を使えば無事に剥離できました。
Review: 印刷しやすく造形物は硬くかなりの剛性感があります。 が、0.4mmハイフローノズルでの印刷には注意が必要です。 200g程印刷したところでノズルが詰まり、吐出出来なくなりました。 様々なノズル詰まり解消法を試しましたが詰まりは取れず、泣く泣くノズルを廃棄しました(高かったのに…) 公式サイトではノズル径0.4mmから対応と記載がありますが、ハイフローノズルは内部でチャネルが分かれている(流路が狭くなる)ため、そこにカーボン繊維が引っかかってしまったのだと思います。 使用の際は流動性確保のため、少し高めの温度、ハイフローでは無い通常ノズル(硬化ノズル)をオススメします。

## Features

- ENHANCED PERFORMANCE & RELIABILITY: Our PET-CF filaments are a high-performance composite blend of polyethylene terephthalate (PET) and carbon fiber. PET-CF 3D filaments provide ease of printing, excellent inter-layer adhesion, excellent mechanical properties for increased rigidity, improved dimensional stability and significant improvement in strength
- SMART FIBER REINFORCED TECHNOLOGY: Carbon fiber forms a mesh skeleton structure within the PET matrix, greatly improving mechanical properties, heat resistance and dimensional stability. Release internal stress to eliminate print warping
- Excellent Dimensional Stability: PET very regular molecular chain structure and rigid benzene ring provide better mechanical characteristics compared to PA or PC materials and less deformation under long loads. Our PET-CF filament reduces warping and shrinkage and maintains the exact dimensions and shapes that are essential for functional components and intricate designs
- LIGHTWEIGHT AND DURABLE: The perfect combination of durability and a lightweight profile, our PET-CF filament is specifically formulated for applications where both strength and weight are a key factor. Due to low moisture absorption rate, the parts are lightweight. It is the perfect material for making robust yet lightweight components such as drone parts, mechanical assembly, and sporting equipment
- VERSATILE: Whether you are a professional who needs reliable, high-strength components or an enthusiast working on detailed and functional projects, our PET-CF filament is versatile enough to meet a wide range of needs. Its printing ease and mechanical properties make it suitable for any application, from industrial prototypes to custom sports equipment

QIDIとBambu Labのナイロン12+CFと同時に購入してみたがフィラメントが硬く丁寧に扱わないと直ぐにポッキリ折れてしまうので困った。何とか装填して印刷できたが、フィラメントを取り換える度に慎重になり過ぎるほど注意せねばならないのが辛い。強度に関しては未だテストしていないがフィラメントの折れやすさが解っているので造形物も脆いのではないかと心配・・・・。
