Prusa Launches Pure PA11 Prusament for Low-Friction Functional Prints

A new Prusament filament built for moving parts

Prusa Research has started shipping Prusament PA11 Natural, an unreinforced polyamide filament designed for functional parts that flex, slide, or take repeated impacts. It is the carbon-free counterpart to the PA11 Carbon Fiber material Prusa launched in 2022, and it trades stiffness for better layer adhesion and lower friction.

The material prints at 275 degrees Celsius with a 100-degree bed and a 55-degree chamber. Prusa recommends drying at 90 degrees for six to eight hours before use, which is standard for nylons. An 800-gram spool costs $122, or about $152 per kilogram. That puts it in the premium filament tier, but the price is in line with other engineering materials.

Why PA11 instead of PA12 or PA6

Most hobbyist nylons are PA12 or PA6. PA6 absorbs moisture quickly and becomes difficult to print within a day of opening the bag. PA12 warps badly and has poor adhesion to standard build surfaces. PA11 sits between them: it is less hygroscopic than PA6 and warps less than PA12, while offering stronger interlayer bonding than either.

The natural color is a translucent yellowish-white with a slight pearlescent finish. Prusa says more colors are in the pipeline, but only Natural is available today.

Who should buy it

This filament makes sense for users who need durable mechanical parts: gears, bearing bushings, rotating joints, and wear surfaces. The low-friction surface finish means parts can move against each other without additional lubrication. The impact resistance is high enough for functional prototypes and end-use parts that see repeated stress.

You will need an enclosed printer with active filtration. The Prusa CORE One+, CORE One L, and Pro HT90 are the recommended machines. Printing PA11 releases a strong odor and emits ultrafine particles, so a well-ventilated or filtered enclosure is not optional.
