Why To Choose Prusament

Prusament is a premium-grade material made by the same people who build the printers. Every spool is manufactured in-house with consistent color and high diameter precision. You can verify it yourself, down to the last meter.

Guaranteed Color Consistency

Every Prusament color is formulated and locked to a documented spectroscopic recipe. We test every batch against the standard before it ships. The result: if you run out mid-project and order a second spool, the colors will match perfectly.

Precise Manufacturing & Strict Quality Control

Our diameter tolerance is the maximum limit, not an average: when we say the diameter tolerance is ±0.04 mm, the real numbers are much lower. We continuously measure and record diameter and ovality across the full length of every spool and publish the actual data.

Spool-level production data can be accessed through the QR code on the spool.

Every Prusament spool comes with the actual measured data from manufacturing: diameter readings along the entire length, weight, and ovality. We're the only filament manufacturer in the world that does this.

Perfect Winding On Every Spool

Our PLA filament is wound under controlled tension on precision machines. Every spool goes through a final inspection before shipping. The result is a spool that feeds smoothly from start to finish. Also, it looks great every time.

Made In The EU And USA

Prusament is manufactured in our facilities in the Czech Republic (Europe) and Delaware (United States). That means faster shipping, lower import duties where applicable, and a supply chain under our full control.

There's no third-party manufacturer who can quietly change a raw material supplier. No surprise batch failures from a factory you've never visited.

Excellent mechanical resistance

Prusament PC Blend is suitable for printing functional components in working machines. It offers great tensile strength, perfect layer-to-layer adhesion, and high impact resistance. We tested it in our Prusament manufacturing line by using this mechanical model of the compounding line motor coupling.

High heat and chemical resistance

Prusament PC Blend resists temperatures up to 113 °C and a wide range of chemicals. This makes it usable for various functional components in the automotive industry. For example, formula racing team AIX Racing’s engineers use Prusament PC-Blend to make various functional parts.

Good electrical insulating properties

PC Blend offers good insulating properties. This is usable for printing structural parts of various electronic devices, such as battery pack cases and more.

Basic Attributes

High temperature resistance (up to 113°C)

High impact and wear resistance (very strong and rigid material)

Good dimensional stability in comparison with other PC filaments

Prints don't deform under pressure over time

Styrene-free (non-toxic compared to ABS and ASA)

Very low moisture absorption (compared to other polycarbonates)

Large models tend to warp (printing in enclosure recommended)

Requires high printing temperatures (not compatible with Original Prusa MINI)

Produces minor odors during printing

New spools with OpenPrintTag

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

Starting October 2025, all Prusament filaments ship on a redesigned spool with a fully rewritable NFC tag powered by the OpenPrintTag standard.

The OpenPrintTag attached to your Prusament spool contains essential data about the material and can be read with the Prusa mobile app. It works entirely offline, it is free to extend, and open for anyone to build upon.

Explore our PC composites with extra properties

The carbon fibers are added to the polymer to improve its qualities. Usually, it improves the material's dimensional stability and high-temperature resistance. We did this with our popular Prusament PC Blend Carbon Fiber, which is highly desired among 3D printing enthusiasts for its great properties and easy printability. And we took it to the next level when we developed the Prusament PC Space Grade: a carbon-filled polycarbonate with excellent outgassing and ESD properties, suitable for space and other vacuum applications.
