Carbon fibre reinforced PC+ filament for stiff, functional 3D printed parts
Carbon Fiber - Standard PC+ Filament - 1.75mm, 3kg is a polycarbonate-based filament with carbon fibre reinforcement for FDM printing. The material is suited to users who need stronger, stiffer parts than typical general-purpose filaments and want a larger 3 kg spool for longer production runs or larger prints.
Carbon fibre filled PC+ combines the heat-resistant, engineering-focused nature of polycarbonate blends with the added rigidity and improved dimensional stability that chopped carbon fibre reinforcement can provide. The result is a practical material choice for structural and end-use prototype work where strength, stiffness, and cleaner geometry matter more than cosmetic flexibility.
Key features of carbon fibre PC+ filament
- Carbon fibre reinforced formulation: Increases stiffness and helps produce parts that feel more rigid and engineering-oriented than standard consumer filaments.
- Polycarbonate-based performance: PC+ is generally selected for functional parts that need better heat tolerance and mechanical performance than PLA or many entry-level materials.
- 1.75 mm filament format: Fits FDM/FFF printers built for the common 1.75 mm standard.
- 3 kg spool size: Supports long print jobs, batch production, and reduced spool changes in print farm or workshop use.
- Better dimensional stability than unfilled PC blends: Carbon fibre reinforcement can help reduce shrink-related behaviour and support more consistent print geometry when the printer is set up correctly.
What to expect when printing carbon fibre PC+
Carbon fibre reinforced polycarbonate blends are engineering materials and need more capable hardware than basic filaments. Reliable printing usually depends on a high-temperature hotend, a heated bed, good bed adhesion, and an enclosure to manage warping and interlayer consistency.
Because the filament is abrasive, a wear-resistant nozzle is the practical choice for repeatable results and stable extrusion over time. Keeping the material dry is also important, since moisture can affect surface finish and print consistency.
Best use cases for carbon fibre reinforced polycarbonate filament
- Functional prototypes: Useful for validating fit, stiffness, and real-world handling in engineering and product development workflows.
- Jigs and fixtures: Suitable for workshop aids that benefit from rigidity and temperature resistance.
- Brackets and mounting parts: A good option for custom hardware, machine accessories, and structural printed components.
- Small-batch production: The 3 kg spool suits users printing repeat parts, multi-part assemblies, or long-duration jobs.
- Enclosed-printer engineering projects: Well suited to makers, prosumers, and small businesses running printers designed for higher-temperature technical materials.
