Prof. Lab PLA Carbon Fiber Gray 1 kg

Professional composite filament PLA + carbon fibers (CF) in Gray for demanding users who require higher stiffness, strength, and a matte technical appearance, while maintaining the printing comfort of standard PLA.

The Gray shade with carbon texture excellently masks layers, leaves a clean matte surface, and is suitable for both functional prototypes and final design parts.

Main advantages and applications

• Reinforced PLA with carbon fibers (~10% CF) – higher stiffness, strength, and stability of parts.
• Matte Gray surface – professional technical look, minimally visible layers.
• Easy printing like classic PLA – does not warp as much as technical plastics, suitable even for less experienced users.
• Low shrinkage and excellent dimensional accuracy – ideal for precisely fitting components.
• Suitable for technical and functional parts – brackets, jigs, covers, mechanical prototypes, RC parts, printer accessories.
• Eco-friendlier base – PLA is a bioplastic based on renewable raw materials.

Typical applications:

• structural and assembly jigs
• sensor, camera, and electronics mounts
• functional prototypes and smaller mechanical parts
• covers, frames, design accessories
• RC models, drones, cosplay elements with higher stiffness

Printing recommendations

According to parameters and recommendations for the Prof. Lab Carbon Fiber PLA series:

• Nozzle temperature: 190–220 °C (start around 200–205 °C and fine-tune based on results)
• Bed temperature: 60–70 °C
• Recommended printing speed: 30–70 mm/s
• Bed: glass, PEI, textured sheet, ideally with adhesive (3Dlac, glue stick, etc.)
• Cooling: medium to high (similar to high-quality PLA)

For best results, we recommend:

• using a more durable brass, hardened, or stainless steel nozzle – the filament is slightly abrasive due to carbon fibers,
• ensuring dryness – store in a closed container with a moisture absorber,
• printing in a well-ventilated room.

Compatibility

• Filament diameter: 1,75 mm – compatible with most FDM/FFF 3D printers.
• Compatible with automatic filament exchange systems (AMS/CFS) if they accept standard spools (typical Prof. Lab spool: approx. Ø 195 mm, width ~57 mm, inner hole 73–75 mm – indicative based on other colors in the series).

Before use in closed multi-material systems, always verify the spool dimensions in your printer's specification.

Storage and filament care

• Keep in the original or resealable bag with a silica gel packet.
• Protect from moisture and direct sunlight.
• During longer printing breaks, we recommend resealing the filament in a dry container.

Safety

• Print in a well-ventilated area.
• Do not touch hot parts of the printer (nozzle, bed) during and shortly after printing.
• Material is not intended for food contact or medical use.
