Filament Renkforce PETG 1.75 mm 1 kg Black spool

Renkforce PETG 1.75 mm 1 kg Black spool is a 1 kg roll of PETG thermoplastic filament designed for FDM 3D printers that accept 1.75 mm filament. The material combines good layer adhesion and chemical resistance with lower warping than many amorphous filaments, making it suitable for printing functional parts, durable prototypes and end-use components. The black colour provides a neutral, uniform finish for visible or concealed parts.

Advantages

PETG offers a balance between strength and ease of printing: it adheres well between layers, resists many chemicals and moisture better than PLA, and is less prone to warping and shrinkage than some engineering plastics. The 1.75 mm diameter ensures compatibility with a wide range of desktop and professional FDM extruders, and the 1 kg spool size supports medium-length print runs without frequent spool changes. The material's mechanical properties make it appropriate for parts that require toughness and some flexibility.

Suitable for

• Functional prototypes and concept models
• End-use components requiring chemical resistance or toughness
• Mechanical parts, brackets and housings
• Small series production and workshop use

Key specifications

• Filament material: PETG (polyethylene terephthalate glycol-modified)
• Diameter: 1.75 mm
• Net weight: 1 kg spool
• Colour: Black
• Form: Wound spool for FDM 3D printers

How to use

Load the spool onto a compatible filament holder and thread the filament through the extruder according to your printer manufacturer's instructions. Typical printing temperature ranges for PETG are higher than PLA; refer to your printer and slicer settings to set an appropriate nozzle temperature and heated bed temperature. Ensure the build surface is clean and use adhesion methods recommended for PETG to avoid first-layer issues. Monitor the first layers and adjust retraction, fan and print speed settings to minimise stringing and achieve consistent extrusion.

Usage recommendations

To achieve reliable results, start with manufacturer-recommended temperature settings for PETG and perform small test prints to fine-tune extrusion and bed adhesion. Store the filament in a dry environment or sealed bag with desiccant to preserve print quality. For parts that require high dimensional tolerance, allow prints to cool fully before measurement and consider post-processing methods such as annealing or surface finishing if needed.
