Prusa Research Prusament PC Blend Jet Black - 970g

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!

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

Because of its strength and toughness, PC Blend is perfect for durable, functional 3D prints. Plus, the PC Blend has high-temperature resistance up to 113 °C / 235 °F. It is an excellent choice for printing mechanically or heat-stressed parts. Thanks to excellent mechanical resistance and good resistance to creep (cold flow), the prints can be used not just as prototypes, but directly as functional parts in production machinery. PC Blend is recommended for experienced 3D printer owners looking for a tough, durable material for the production of prototypes and functional parts, thermally and mechanically stressed components.

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
+ Good electrical insulating properties
+ Styrene-free (non-toxic compared to ASA)
+ Very low moisture absorption

- Large models have a tendency to warp
- Requires high heatbed and nozzle temperatures
- Produces minor odors during printing

Beginners tips & tricks

Prusament PC Blend is suitable for advanced users. If you are new to 3D printing, we recommend you start with easier-to-print materials such as PLA and PETG, then try advanced materials, such as PC Blend.

You may encounter some issues related to shrinking (warping) of the material - especially when printing larger models. This effect is much less severe compared to other polycarbonates but still, even with the heatbed set to 110°C, the prints can shrink and warp, causing them to detach from the print bed. This issue can be eliminated by printing inside an enclosure or by adding a tall skirt around the object.

Notes

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.
