Prusament PC Blend Filament - 900G - 1.75mm (Multiple Colors)
$56.99
Prusament PC Blend is manufactured in-house by Prusa Research with a guaranteed ±0.03mm diameter tolerance. Its strength, rigidity, and resistance to impact, wear, and high temperatures up to 113 °C make it well suited to functional parts that need to hold up under stress. Every spool is measured and documented throughout manufacturing, and this production data ships with the spool.

Prusament PC Blend
Prusament PC Blend is Prusa's in-house polycarbonate filament, built for strong, functional parts. It stays rigid under load, handles impact and wear, and holds its shape at temperatures up to 113 °C, which suits mechanical and heat stressed components that PLA or PETG can't handle. It also resists creep, stays tough even at low temperatures, is styrene-free, and absorbs very little moisture, so there's no need to dry it before printing. Every 900 g spool holds a diameter tolerance of ±0.03 mm and ships with measurement data to back it up.
Why Choose Prusament
Prusament is made by the same team that builds Prusa printers, and all of it is manufactured in-house. Every spool is held to a ±0.03 mm tolerance with closely controlled color, and you can check that quality yourself along the entire length.
Made By Prusa
Prusa wasn't satisfied with the filament on the market, so they decided to make their own. Prusament is built to the standard a printer maker expects from the filament running through its own machines.
Premium Materials, Tested
Prusament starts with premium-grade raw material, and every stage of production is monitored and tested for diameter, color consistency, and mechanical properties, so every spool that ships is right.
Quality Reports
Each spool ships with its own production data, including diameter readings along the full length, total weight, and ovality. It's something no other filament maker provides, and it lets you confirm the quality yourself.
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.
Mechanically Stressed Parts
Strong, tough, and rigid where it counts
PC Blend is strong, tough, and rigid, which makes mechanically stressed parts the standard use case. It resists impact and wear, stays tough even at low temperatures, and holds its form under load. The best choice for components that take a beating.
High-Temperature Resistant Parts
Keeps its shape in heat up to 113 °C
With heat resistance up to 113 °C, PC Blend handles parts that sit close to motors, electronics, or other heat sources, where PLA or PETG would soften and lose their shape. That makes it a great choice for heat-stressed components, including a printer's own fan shroud, that have to keep working when things get warm.
Functional Engineering Parts
Strong enough to go straight into the machine
Thanks to excellent mechanical resistance and good resistance to creep, PC Blend parts can go straight into production machinery instead of serving only as prototypes. Prusa even runs PC Blend in a part that transmits the full torque of its own compounding line, exactly the kind of sustained, load-bearing duty the material is built for.
Pros & Cons
Pros
✓ Strong, rigid, and impact-resistant
✓ High-temperature resistance up to 113 °C
✓ Good dimensional stability compared with other polycarbonates
✓ Resists creep, so parts keep their shape under sustained load
✓ Styrene-free and a good electrical insulator
✓ Very low moisture absorption
✓ Less warping and layer cracking than conventional polycarbonates
Cons
✕ Large models are prone to warping
✕ Needs high nozzle and heatbed temperatures
✕ Produces a noticeable odor while printing
✕ Requires a separating agent (glue stick) on the print sheet
✕ Best suited to experienced users
Print Preparation
Get the sheet, separating agent, and cooling right
PC Blend isn't abrasive, so a standard 0.4 mm brass nozzle is perfect. The important point is the print surface. Always apply a separating agent first, a thin layer of paper glue stick (such as Kores) on a PEI or powder-coated sheet. PC Blend is the exception that needs glue even on a textured powder-coated sheet; without it, adhesion can be strong enough to damage the sheet.
Large parts can warp as they cool, far less than other polycarbonates, but still enough to lift off the bed. A tall skirt around the model, or better still a printer enclosure, keeps temperatures stable and helps prints stay down. Keep the machine out of cold drafts, and run part cooling low, around 20%.
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.
