Review: One of the best ABS filaments I've used, and great value - Excellent Filament. Prints easily, minimal warping compared to pure ABS, super stiff, but still has good layer adhesion. Probably my new go-to for temperature resistant functional prints. Much easier to print than regular ABS/ASA, and the added glass fibres give a really nice exterior finish. Remarkably low odour too; Forgot to turn on my carbon filter and was quite a while before I noticed any smell. The only critique, which is a common issue with Siraya Tech, is that the spool is wound almost to the edge. Very neat windings, but unless there's constant tension on the spool, it's quite easy for a few loops to come off, at least until you've used a couple 100gs. Not really that big an issue though, and definitely still one of the best ABS filaments regardless. Great value too. I should say, the bed adhesion is almost too good. I normally use adhesive and a hot chamber to print ABS with minimal warping, but the same process with this filament ripped the PEI right off my build plate. Not a fault of the filament; definitely user error. But be aware of this if you normally use a strong adhesive for printing ABS (Magigoo, NanoPolymer, etc.)
Review: Impressive value for money filament - Really nice print quality. Needs some fiddling with print and process settings on Bambu printers but possible with some wiki work! No stringing, great value for an engineering filament, perfect bed adhesion (even without glue) and seems to have good temperature tolerance. Excellent functional filament for projects that need high temperature tolerance, strength, nutrition n-electrical conductivity and beautiful finish!

## Features

- Improved Performance & Reliability Our PET-CF filament is a high-performance composite material that combines polyethylene terephthalate (PET) with carbon fibers. The PET-CF 3D filament ensures easy printability, good layer bonding and excellent mechanical properties. It offers increased rigidity, improved dimensional stability and significantly higher strength.
- Intelligent fiber reinforcement technology: Carbon fibers form a mesh skeleton within the PET matrix, which significantly improves the mechanical properties, heat resistance, and dimensional stability. Thanks to the internal stress release, no deformation occurs.
- Superior dimensional stability: The highly regular molecular chain structure of PET and the rigid benzene rings result in better mechanical properties and less deformation under long-term stress compared to PA and PC materials. Our PET-CF filament reduces warping and shrinkage, ensuring your prints maintain their precise dimensions and shapes – crucial for functional parts and complex designs.
- LIGHTWEIGHT AND DURABLE Our PET-CF filament offers a perfect balance between longevity and a lightweight profile. Its low moisture absorption makes it ideal for applications where both strength and weight are crucial factors. It is an excellent material for making robust but lightweight components such as drone parts, mechanical assemblies and sports equipment.
- Versatile Applications: Whether you need reliable, high-strength components as a professional or work on detailed, functional projects as a hobbyist – our PET-CF filament is versatile enough to meet a variety of requirements. Its easy printability and mechanical properties make it suitable for everything from industrial prototypes to custom sports equipment.

### ⭐⭐⭐⭐⭐ Tough Filament
*by G***L on 2 January 2026*

This is the first PET CF filament I tried so I cannot compare it to others. All I can say is the resulting prints are very tough and rigid. Dry, dry, dry, absolutely necessary with this filament as you're no doubt aware. Straight out of the vacuum sealed bag it was pretty good but after a day the prints were rough. Heated dryer was purchased (Creality Official Space PI Filament Dryer Plus) and this resulted is perfect prints. Attached pic, two bottom components printed from freshly opened bag. Top after drying for 12 hrs at 65 deg C. Note the glossy textured finish and lack of layer lines, its actually better than depicted. The print between opening the bag and drying the filament went straight into the bin, ragged and rough. This was circa 12hrs exposed to UK cold and humidity. I thought I would try and pull the print apart to see just how strong it was, absolutely no chance. It opened up a little at the clamping end but went no further. Overall, great value for money, print using the specified parameters, keep it dry.
