Prusament PC Blend is Prusa's own polycarbonate filament, made for parts that have to do a real job. It stays stiff under load, takes impact and abrasion in stride, and keeps its shape up to 113 °C, which puts it ahead of PLA or PETG for mechanically and thermally demanding work. On top of that it resists creep, stays tough in the cold, contains no styrene, and picks up so little moisture that you can print it without drying first. Every 900 g spool is made to a ±0.03 mm diameter tolerance and ships with the measured data to prove it.
Prusament comes from the same people who design Prusa's printers, produced entirely in-house rather than sourced from a third party. Each spool is made to a ±0.03 mm tolerance with tightly controlled color, and the data lets you verify that consistency from the first meter to the last.
Unhappy with what the filament market offered, Prusa started making its own. The result is held to the standard a printer manufacturer expects from the material feeding its own machines.
It begins with premium-grade resin, and every production stage is checked for diameter, color, and mechanical performance, so nothing leaves the line unless the spool measures up.
Every spool comes with the real numbers from its run: diameter logged along the whole length, plus weight and ovality. No other filament maker hands you that, so you can confirm the quality rather than take it on faith.
Made in the EU and USA
Prusament is produced in Prusa's own plants in the Czech Republic and in Delaware, USA, not handed off to some anonymous supplier. Keeping production in-house means quicker shipping, lower import duties where they apply, and a supply chain Prusa controls end to end. No outside factory is free to swap a raw material behind the scenes, so there are no nasty batch surprises from a site nobody has set foot in.
Built to take a mechanical beating
Strength, toughness, and rigidity are what PC Blend does best, which is exactly why mechanically stressed parts are its bread and butter. It stands up to impact and wear, keeps its nerve even in the cold, and holds its form under sustained load, making it a dependable pick for the components in a build that take the most punishment.
Holds its form in heat to 113 °C
Rated to 113 °C, PC Blend stays put in spots that sit near motors, electronics, or other heat sources, places where PLA or PETG would soften and distort. That suits it to heat-stressed parts, a printer's own fan shroud being a classic example, that have to keep functioning as the temperature climbs.
Ready for real production duty
Strong mechanical properties paired with solid creep resistance mean PC Blend parts can be put to work in production machinery, not just used as prototypes. Prusa relies on it for a component that carries the full torque of its own compounding line, precisely the kind of constant, load-bearing job the material was made for.
Sheet, separating agent, and cooling, the essentials
PC Blend isn't abrasive, so an ordinary 0.4 mm brass nozzle handles it fine. The part that matters is the print surface: lay down a separating agent first, a thin smear of paper glue stick (Kores, for instance) over a PEI or powder-coated sheet. PC Blend is the one material that wants glue even on a textured powder-coated sheet, since without it the bond can get strong enough to damage the surface.
Big parts still tend to warp as they cool, far less than other polycarbonates, but enough to peel off the bed. A tall skirt around the model, or better yet an enclosure, holds the temperature steady and keeps prints anchored. Keep the printer clear of cold drafts, and dial part cooling down to roughly 20%.
New spools with OpenPrintTag
Since October 2025, every Prusament spool arrives on a redesigned reel carrying a fully rewritable NFC tag built on the OpenPrintTag standard.
It stores the filament's key details and reads straight into the Prusa mobile app. The tag runs completely offline, is free to extend, and stays open for anyone to build on.
