Made in the EU and USA

Made in-house.
Never outsourced.

Prusament is made in Prusa's factories in the Czech Republic and Delaware, USA, not farmed out to an unknown supplier. Making it in-house means faster shipping, lower duties where they apply, and full control of the supply chain. No outside factory can quietly switch a raw material, so there are no surprise batch failures from a plant nobody has inspected.

Carbon Fiber Reinforced

Stronger, stiffer, and easier to print than plain PC

Blending carbon fibers into the polycarbonate base raises its strength, stiffness, and tensile performance while keeping the high impact and wear resistance PC is known for. The fibers also make the material easier to run than unfilled PC Blend, so you get demanding technical parts without the usual polycarbonate headaches. The trade-off is that PCCF is a little more brittle than standard PC Blend, and the carbon content gives it a clean matte black finish.

High-Temperature Resistance

Holds up to 114 °C, or 130 °C after annealing

PCCF keeps its shape in heat up to 114 °C, so it's at home near motors, electronics, and other heat sources where PLA or PETG would soften and deform. If you need even more headroom, annealing the printed part pushes its temperature resistance up to around 130 °C. It's a dependable pick for thermally stressed components such as fan shrouds and other parts that have to keep working when things get hot.

Dimensional Stability

Print large parts, no enclosure required

The carbon fibers give PCCF excellent dimensional stability, which means far less warping than you'd expect from polycarbonate. In practice you can print large models without an enclosure, something pure PC Blend struggles with, and its low creep means functional parts can go straight into working machines. It also offers good UV stability and resistance to common chemicals, and there's no need to dry the filament before printing.

New spools with OpenPrintTag

Smarter spools. Open standard.
No cloud lock-in.

From October 2025, every Prusament spool ships with a redesigned, fully rewritable NFC tag built on the OpenPrintTag standard.

The tag holds the filament's key details and can be read with the Prusa mobile app. It works fully offline, costs nothing to extend, and is open for anyone to build on.
