Filament BambuLab PETG HF 1.75 mm 1 kg with reusable spool — Gray

BambuLab PETG HF 1.75 mm 1 kg filament in gray is a polyester-based 3D printing material supplied on a reusable spool. Designed for FDM printers that accept 1.75 mm filament, PETG HF combines improved toughness and chemical resistance with relatively straightforward printing behaviour compared with brittle materials. The gray color provides a neutral, practical finish suitable for visible parts, prototypes and functional components. The reusable spool reduces waste and can be refilled for subsequent spools.

Advantages

PETG HF offers a balance of mechanical strength and durability while remaining easier to print than many engineering-grade polymers. It provides good layer adhesion and impact resistance, and demonstrates improved resistance to common chemicals and moisture compared with standard PLA. The reusable spool simplifies storage and handling and helps reduce packaging waste.

Suitable for

• Functional prototypes and end-use parts that require toughness
• Mechanical components such as brackets, clips and housings
• Everyday prints and replacement parts for tools and appliances
• Visual prototypes where neutral gray finish is preferred

Key specifications

• Material: PETG (polyethylene terephthalate glycol-modified)
• Diameter: 1.75 mm nominal
• Net filament weight: 1 kg
• Color: Gray
• Packaging: Reusable spool

How to use

Load the 1.75 mm filament onto your FDM printer spool holder and feed it through the extruder following the printer manufacturer's instructions. Typical print settings for PETG HF include a nozzle temperature commonly in the range suitable for PETG (consult your printer and filament guidance), a heated bed to reduce warping, and moderate print speeds to balance surface finish and mechanical properties. Ensure the filament is handled to avoid moisture uptake before printing; dry filament prints more consistently. Clean the nozzle and perform a small test print to confirm adhesion and dimensional accuracy before starting larger jobs.

Usage recommendations

Store the filament on the reusable spool in a cool, dry place and use desiccant if long-term storage is expected. When switching from other materials, purge the hotend to avoid contamination. For best strength and surface quality, tune retraction, print temperature and cooling settings on your specific FDM printer.
