## At a glance

- Carbon-fibre-reinforced PA12 nylon, with the listing stating 20% carbon fibres and 80% PA nylon.
- Manufacturer claims resistance to grease, gasoline and solvents, and suitability for wear-prone moving parts.
- The heat-resistant spool is described as suitable for drying, with a stated maximum drying temperature of 110℃.
- The listing recommends drying before printing and using a wear-resistant nozzle, it also suggests glue to reduce edge warping.

## Pros

- Material composition and spool measurements are supplied, helping buyers assess material type and holder fit.
- The stated drying schedules and print settings offer a starting point for tuning this engineering filament.
- The listing describes a use case for oil-exposed or friction-prone parts, which may suit functional prototypes and workshop components.

## Cons

- The manufacturer’s recommended drying step and wear-resistant nozzle guidance add preparation and hardware requirements compared with less demanding filaments.

## Before you buy

- The listing describes this as PA12-CF and claims up to 175℃ temperature resistance, but gives no test conditions, treat that figure and the oil, wear and moisture claims as manufacturer statements, not guaranteed finished-part performance. Dry before printing as directed, consider glue to reduce warping, and avoid a copper nozzle because the listing warns it may wear, check spool measurements against your holder.

## A good fit for

- Owners of compatible FDM printers seeking carbon-fibre nylon for functional or wear-prone parts.
- Buyers prepared to dry filament and use a wear-resistant nozzle for printing.

## Less suited to

- Users looking for a low-preparation filament or who cannot meet the stated drying and nozzle recommendations.
- Buyers needing independently substantiated heat, oil, fuel or moisture performance figures.

## Customer feedback

Customer feedback reports positive impressions of print quality, finish and appearance, with some customers describing strong prints and straightforward printing. Durability and adhesion experiences are mixed: some report strength and good adhesion, while others describe brittleness or poor adhesion. Tangling and winding are also raised as concerns. These experiences matter for functional parts, where consistent feeding and layer bonding are important, the rating alone does not establish why customers had different results. The aggregate score is 4.5 out of 5 from 822 ratings.
- Positive themes: Customers report good filament quality and print quality, and positive feedback on finish and appearance.
- Positive themes: Some customers say it produces strong prints and prints well straight from the pack.
- Negative themes: Customers report tangling and a poorly wound spool.
- Mixed feedback: Durability and adhesion receive mixed feedback: some customers report strength and no adhesion problems, while others describe brittleness or poor adhesion.
