## At a glance

- Listing specifies 20% carbon fibers in PA nylon and claims improved stiffness, strength and heat resistance.
- Manufacturer lists heat resistance up to 209°C, this is a product claim, not an independently verified performance result.
- The listing requires drying before printing and recommends abrasion-resistant nozzles such as hardened steel.
- Listing warns the filament is not recommended for AMS, AMS Lite or other multicolor systems.

## Pros

- The listing provides specific drying, nozzle, bed, speed and annealing guidance, useful for planning a demanding nylon print.
- A stated 1.75 mm diameter and spool dimensions help buyers compare it with printer and holder requirements.
- Carbon-fiber reinforcement is intended for stiff, strong parts and heat-resistant applications.

## Cons

- The required pre-print drying and recommended annealing add preparation and post-processing steps.
- The manufacturer warns that this brittle filament is not recommended for AMS, AMS Lite or other multicolor systems.

## Before you buy

- Manufacturer printing guidance: dry at 80°C for 24 hours or 110°C for 4 hours, nozzle 270-290℃, bed 50-70℃, speed 50mm/s – 150mm/s, and optional recommended annealing at 80℃~130℃ 5-12h. The listing says a thin coat of PVA glue or Magigoo PA can be used on almost any bed surface and recommends abrasion-resistant nozzles. Customer feedback is mixed: some report good prints when fully dried and a matte finish, while others mention brittleness, clogging, poor adhesion, tangling and jams.

## A good fit for

- Printer owners seeking carbon-fiber-reinforced nylon for stiff parts and who can dry filament before printing.
- Buyers whose printer accepts 1.75 mm filament and whose spool setup fits the listed dimensions.
- Users prepared to tune printing and consider annealing for parts intended for elevated-temperature use.

## Less suited to

- Users who need AMS, AMS Lite or another multicolor feed system, which the listing does not recommend for this filament.
- Buyers seeking a simple, no-drying printing workflow.

## Customer feedback

Customer feedback is mixed despite an aggregate 4.3 out of 5 stars from 385 ratings. The supplied feedback describes good prints when the filament is fully dried and a matte appearance, but also reports varying impressions of strength and brittleness, plus clogging, poor adhesion, tangling and jams. Those concerns matter particularly for a moisture-sensitive nylon workflow that already requires drying and is not recommended for multicolor feed systems, ratings alone do not explain the different experiences.
- Positive themes: Customers report good prints when the filament is fully dried and a matte finish.
- Negative themes: Customers report poor adhesion, tangling and printer jams.
- Mixed feedback: Feedback varies on quality and durability: some describe strong results, while others report brittleness, clogging is also reported.

## Frequently asked questions

### Does the listing recommend this filament for AMS?
No. It says the filament can be brittle and prone to breaking inside the printer, and is not recommended for AMS, AMS Lite or other multicolor systems.
### Does it need drying before printing?
Yes. The listed drying options are 80°C for 24 hours or 110°C for 4 hours.
### What printer settings does the listing give?
It lists a 270-290℃ nozzle, 50-70℃ bed, and 50mm/s – 150mm/s speed. It also gives annealing guidance of 80℃~130℃ 5-12h.
### What heat resistance does the manufacturer claim?
The listing claims the PA6 filament withstands up to 209°C. Treat this as a manufacturer claim rather than a verified result for a particular printed part.
