Siraya Tech Fibreheart PET-CF 3D Filament is a high-performance composite material that blends Polyethylene Terephthalate (PET) with carbon fiber, offering enhanced stiffness, dimensional stability, and strength. This filament is designed for applications requiring both durability and lightweight properties, making it ideal for drone parts, mechanical assemblies, and sporting equipment.

Users have reported mixed experiences with this filament. Some found it challenging to manage due to its brittleness and severe bed adhesion issues, which even led to the ruin of a build plate. However, after reaching out to the company, they received a replacement roll that performed significantly better, printing beautifully with minimal effort and producing strong, precise prints.

Print settings can be tricky as they vary between the label on the bag and the website. Users recommend using nozzle temperatures between 280-300°C and bed temperatures between 80-100°C. Despite these challenges, many users have successfully printed high-quality parts with excellent finish and minimal warping.

Customer service from Siraya Tech has been praised for being responsive and supportive, often going above and beyond to address user concerns. This level of support adds significant value to the product.

Overall, while the Siraya Tech Fibreheart PET-CF filament may require some initial adjustments and experimentation with print settings, it offers impressive performance when handled correctly. Its combination of strength, lightweight properties, and excellent customer support makes it a worthwhile investment for both professionals and hobbyists.
