Filament BambuLab PETG Refill 1.75 mm 1 kg — Translucent Gray

BambuLab PETG Refill 1.75 mm 1 kg — Translucent Gray is a spool of PETG filament formulated for FDM/FFF 3D printers. The filament combines mechanical strength, chemical resistance and moderate flexibility, delivering reliable performance for functional parts, prototypes and end-use components. The translucent gray finish provides partial light transmission and a neutral aesthetic suited for technical models and consumer products where visibility of internal structures or a muted appearance is desired.

Advantages

The PETG material balances toughness and printability: it is less brittle than PLA and easier to print than ABS for many setups. Its chemical resistance and layer adhesion make it suitable for mechanically stressed parts and housings. The 1.75 mm diameter and consistent extrusion quality support stable flow rates and predictable dimensional accuracy on a wide range of FDM printers. The translucent gray color enables visual inspection of internal features while maintaining a professional, neutral look.

Suitable for

• Functional prototypes and mechanical parts that require impact resistance and good layer bonding
• End-use components such as enclosures, brackets and mounts with moderate thermal demands
• Visual models where partial translucency and neutral coloration are desired
• Parts exposed to mild chemicals or moisture where improved resistance over PLA is helpful

Key specifications

• Material: PETG (glycol-modified PET)
• Diameter: 1.75 mm nominal
• Spool weight: 1 kg filament mass
• Color/finish: Translucent gray with partial light transmission
• Compatibility: FDM/FFF 3D printers accepting 1.75 mm filament

How to use

Load the 1.75 mm filament spool onto a compatible FDM/FFF 3D printer following the printer manufacturer’s loading procedure. Use nozzle and bed temperatures appropriate for PETG—typical starting points are 230–250 °C for the hotend and 60–80 °C for the heated bed—then fine-tune settings for adhesion, flow and retraction based on your printer and model geometry. Ensure good filament feeding and clear the nozzle before printing if switching materials. Allow printed parts to cool gradually for better dimensional stability and inspect layer bonding and surface finish after printing.

Usage recommendations

For best results, print PETG on a clean, lightly textured build surface and consider using a brim or skirt for improved first-layer adhesion. Reduce retraction distance and speed compared to PLA to limit stringing; adjust cooling fan settings moderately—too much cooling can reduce layer adhesion. Store unused filament in a dry, sealed container with desiccant to prevent moisture uptake, which can affect print quality.
