Professional Lab PETG CF Red 1 kg

Professional Lab PETG CF Red 1 kg

Professional Lab PETG CF is a composite PETG filament with carbon fibers, which combines the easy printability of classic PETG with even higher stiffness, dimensional stability, and a significantly lower tendency to warp. In the red version, it creates a professional matte surface that masks layers perfectly and is suitable for both technical and design parts. This material is intended for users who need strong, precise, and durable prints – for example, brackets, mounting jigs, functional components, robotics components, RC models, electronics covers, and other demanding mechanical parts.

Key Features

• PETG + carbon fiber (CF) composite – higher stiffness and strength than standard PETG.
• Matte technical surface – minimal gloss, perfectly masks layers and small imperfections.
• Excellent dimensional stability – low shrinkage and less tendency to warp, suitable for precise parts.
• Good chemical and thermal resistance – suitable for functional and slightly thermally stressed components.
• Excellent layer adhesion – strong bonds, high mechanical resistance against cracking.
• Red color – distinctive technical look for functional parts, increased visibility of components.

Recommended Use

Professional Lab PETG CF Red is ideal for:

• Functional and structural parts (brackets, mounts, jigs, adapters)
• RC models and robotics (arms, motor mounts, frame parts)
• Technical prototypes and load testing parts
• Electronics covers and protective elements where a combination of appearance and strength is needed
• Parts with requirements for dimensional accuracy and minimal deformation

Technical Parameters

• Material: PETG composite with carbon fibers (PETG CF)
• Color: Red
• Filament diameter: 1,75 mm
• Diameter tolerance: ±0,02–0,03 mm (typically according to the Professional Lab series)
• Spool weight: 1 kg of net filament
• Winding type: on a plastic spool, vacuum packed

Recommended Print Settings

Specific values may vary depending on the printer, nozzle, and environmental conditions. Use these as a starting point.

• Nozzle temperature: 230–260 °C (recommended around 245 °C for good layer bonding)
• Bed temperature: 70–90 °C
• Print speed: approx. 30–70 mm/s
• Cooling: 20–50 % (less for maximum strength, more for details)
• Bed: PEI sheet, textured PEI, glass with adhesive, or special surfaces for PETG/CF

Tips for Successful PETG CF Printing

• Use a hardened nozzle – carbon fibers are abrasive and quickly wear out brass nozzles. Hardened steel or another durable material is recommended, min. diameter 0,4 mm.
• Increased retraction and lower speed can help reduce stringing and ensure stable material flow.
• Ensure good degreasing of the bed (isopropyl alcohol) and an appropriate combination of bed temperature and surface for reliable adhesion.
• Store the filament dry, ideally in a sealable box with desiccant – PETG partially absorbs moisture.

Who is this filament suitable for

• Advanced hobby users and professionals who already have experience with PETG printing and want to push the strength and technical properties of their prints to a higher level.
• Manufacturing companies, prototyping workshops, and technical laboratories where a combination of strength, precision, and repeatability is required.

Summary

Professional Lab PETG CF Red 1 kg is an excellent choice for anyone who needs a technical, strong, and dimensionally stable filament with carbon fibers and wants to highlight their prints with a rich red color and matte surface. Due to its properties, it is suitable for long-term functional components and demanding mechanical parts where regular PETG or PLA is not enough.

Key Features:

• Composite PETG filament with carbon fiber additive (PETG CF) for high strength and stiffness
• Matte technical surface in red color, which perfectly masks print layers
• Excellent dimensional stability and low warp compared to standard PETG
• Good chemical and thermal resistance – suitable for functional and mechanically stressed parts
• High layer bonding strength thanks to carbon reinforcement
• Ideal for brackets, jigs, RC models, robotics, and technical prototypes
• Filament on a 1kg spool with 1,75 mm diameter and tight diameter tolerance
• Recommended to use a hardened nozzle due to the abrasiveness of carbon fibers
