What can you expect?
Prusament PC Blend is our own in-house made filament. The whole manufacturing process is closely monitored and tested - we guarantee ±0.03mm precision and highly-consistent colors. You can inspect the parameters of every spool we made at prusament.com. Check the sample spool!
Glue for printbed included with every Prusament PC Blend.
Manufactured In-House By Josef Prusa
We were not satisfied with the quality of filaments on the market. So we decided to make our own! Prusa Research is the only 3D printer manufacturer with its own filament production.
Premium-Grade Materials And Thorough Testing
The whole manufacturing process is closely monitored and tested – string diameter, color consistency, and mechanical properties – to make sure that every spool is perfect.
± 0.03 mm Manufacturing Guaranteed Precision
We believe the industry standard of 0.05 mm isn’t sufficient for perfect 3D printing. Instead, we guarantee ±0.03mm precision and highly-consistent colors in our filaments.
High Quality You Can Check Yourself
We are the only manufacturer that gives the option to inspect parameters of every filament spool. Scan a QR code on the spool to see all details online (check the sample spool).

About PC Blend
Prusament PC Blend (PolyCarbonate) is the perfect material for stronger, more durable 3D prints.
Polycarbonates are a group of plastics that are known for their strength, mechanical durability, toughness, and temperature resistance. They are commonly used for the production of CDs, protective goggles, or car headlights.
The composition of pure polycarbonate is a material not suitable for 3D printing. It adheres very poorly to the print sheet, and due to its high thermal expansion, it has a tendency to deform and crack. We have added carefully-picked additives into the mix, improving the adhesion and reducing cracking and warping, while still maintaining the excellent properties of polycarbonate.
Prusament PC Blend is suitable for advanced users. If you are new to 3D printing, we recommend you to stick with easier to print materials such as PLA and PETG. PC Blend is recommended for experienced 3D printer owners looking for tough, durable material for production of prototypes and functional parts, thermally and mechanically stressed components.
Print sheet preparation
Prusament PC Blend can be printed on both smooth and textured print sheets. However, it’s required to spread a separating agent on the sheet before you start printing, otherwise the adhesion of the print may be too strong. The best way to prepare your print sheet is to apply a thin layer of paper glue onto the sheet. This is why we bundle a paper glue stick (KORES) to every PC Blend spool for free. Failing to add a separating layer may lead to the damage to your print sheet!
After you finish printing and remove the object from the print sheet, use isopropyl alcohol to clean the print sheet thoroughly! Avoid cleaning the textured sheet with water - it may lead to corrosion.

Large models have a tendency to warp
High temperature resistance up to 113°C
Requires high heatbed and nozzle temperatures
Good dimensional stability in comparison with other PC filaments
High impact and wear resistance
Produces minor odors during printing
Prints don't deform under pressure over time
Low warping, layer cracks are very rare
Very low moisture absorption
This PC Blend is made in-house by Prusa Research.
1.75 mm filament is manufactured with a precision of ±0.03 mm.
Prusament PC Blend has a new formula since 9. 6. 2021 The material density is now slightly lower than before, resulting in a minimal spool weight of 970 g. The approximate length of the filament is 330 m - the same length as the standard Prusament.To dry the filament, please follow the instructions in our article
I've been printing Natural PC Blend on an MK3s+. I've had very good results using the stock PC Blend settings in Prusa Slicer with a stock brass nozzle printing on the new Satin Sheet. I carefully calibrated the first layer for the Satin Sheet. Using 275 nozzle; 110 bed. I do print in an enclosure with a recirculating fan (no outside air) and an activated carbon filter for odor. Not sure the odor filter is needed but won't hurt. I had to use a brim to avoid warping on a piece about 10mm X 15mmX 60mm. Sticks very well with the brim in place, the piece will pop right off the sheet if allowed to cool, or when still warm (not hot) a bend of the plate and it pops off. Not using any glue or tape, just printing to the bare sheet. Very happy with the filament printing on the satin sheet.

Mechanically the best on the market after pure polycarbonate which requires active hot chamber, to print fan off, abundant brim, for small prints it is fine without enclosure, becomes necessary for large and heavily filled prints. Tried directly on textured PETI (although not recommended I had no problem peeling it off, comes off by itself below 75 degrees, no need to force it. Tried it with the included glue, it does its job, nothing outstanding in terms of adhesion. Best result I got with magicgoo pc on textured pei, but not worth applying if prints are small.
