C-TECH PETG 1.75 mm 1 kg filament spool for FDM 3D printers, black

C-TECH PETG 1.75 mm black filament on a 1 kg spool is designed for FDM 3D printers and intended for functional parts, prototypes and durable prints. The filament combines tensile strength and moderate flexibility, with good layer adhesion and resistance to many common chemicals. This material delivers consistent extrusion and dimensional stability for general-purpose printing tasks while maintaining ease of use on standard hotend setups.

Advantages

PETG offers a balance between the rigidity of PLA and the toughness of ABS, providing improved impact resistance and less brittleness. The filament's 1.75 mm diameter and controlled spool winding contribute to stable feeding and fewer extrusion interruptions. Its chemical resistance and low moisture sensitivity after proper drying make it suitable for parts that need durability and moderate environmental resistance. The black color ensures uniform appearance for aesthetic or functional components.

Suitable for

• Functional prototypes and mechanical parts
• End-use components requiring impact resistance
• Housings, brackets and fixtures for indoor applications
• Visual models and jigs where a consistent black finish is needed

Key specifications

• Material: PETG (polyethylene terephthalate glycol-modified)
• Nominal diameter: 1.75 mm
• Spool weight: 1 kg net filament
• Color: black
• Typical printing temperature range: 230–250 °C (dependant on printer and nozzle)
• Recommended bed temperature: 60–80 °C for improved adhesion
• Filament tolerance: commonly ±0.02–0.05 mm (verify with actual batch data)

How to use

Load the filament into a compatible FDM 3D printer with a 1.75 mm filament path. Preheat the nozzle to the recommended temperature range and the build plate to the suggested bed temperature. Ensure the nozzle and extruder are clean before printing to avoid contamination. Use moderate print speeds and enable retraction settings tuned for PETG to reduce stringing. Allow printed parts to cool gradually on the bed or after removal to preserve dimensional accuracy.

Usage recommendations

Store the filament in a dry environment or sealed container with desiccant to minimize moisture uptake. If the filament shows signs of bubbling or poor extrusion, dry it at low temperature in a filament dryer or oven before use. For best layer adhesion, calibrate extrusion multiplier and first-layer settings; use a brim or skirt for improved bed adhesion when printing larger or taller parts.
