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. 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.

Printing Setup

Basic Attributes

• Styrene free
• Large models have a tendency to warp
• High temperature resistance up to 113°C
• Requires high heatbed and nozzle temperatures
• Produces minor odors during printing
• Higher price
• Prints don't deform under pressure over time
• Good dimensional stability in comparison with other PC filaments
• Low warping, layer cracks are very rare
• Very low moisture absorption
• High impact and wear resistance

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. 

What can you expect?

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).
