Prusament PA11 Carbon Fiber Black 800g (NFC)

It is necessary to use a hardened nozzle. Carbon fibers are a highly abrasive material and may damage brass nozzles.

Prusament PA11 Carbon Fiber, in particular, can easily peel and warp when printed on conventional sheets, despite being filled with carbon fiber. That’s why we have developed a new surface layer of a special material that provides significantly better adhesion for polyamide printing materials. The only downside is that this print sheet gets damaged when cleaned with isopropyl alcohol. Instead, optimal adhesion is achieved when the sheet's surface is washed with water.

If the absorbed humidity reaches high levels, the print quality will deteriorate. Deterioration occurs between a few days and a month. If you are not sure how long it has been since you opened the sealed bag or if you haven’t been printing for a long time, we recommend drying the filament at 90 °C for 6 hours before printing. Absorbing moisture may sometimes be noticeable when supports are removed. If the filament is dry, support removal should be easy.

We recommend printing in a well-ventilated room because PA11 with carbon fibers may release a noticeable odor into the air and produce ultra-fine particles. Printing on an enclosed 3D printer helps contain the odors and particles, plus the increased temperature may improve layer-to-layer adhesion.
