SUNLU PETG 3D Printer Filament - Transparent Yellow, 1.75mm, 1kg
SUNLU PETG in Transparent Yellow is a see-through version of SUNLU's popular PETG filament, made for prints that need both strength and a glass-like finish. It lets light pass through while keeping the toughness PETG is known for. This 1kg spool of 1.75mm filament is a reliable everyday engineering material for hobbyists, schools, print farms and workshops across India.
The filament is produced with laser-monitored diameter control and held to a tight 1.75 ± 0.02 mm tolerance, which keeps extrusion flow stable and avoids under-extrusion on long prints. SUNLU's neat, automated winding lays the filament cleanly on the spool, preventing knots and tangles that cause mid-print failures. It runs on 99% of FDM printers on the market - Bambu Lab, Creality, Anycubic, Prusa, Elegoo and more - with no special tuning needed.
Key Features
- Excellent layer adhesion: reduces warping and keeps layers bonded for smooth, strong prints with great structural integrity.
- Enhanced toughness: PETG outperforms PLA in durability, ideal for sturdy parts that see real stress and daily use.
- High impact strength: parts endure bumps and drops without cracking, for long-lasting functional performance.
- Indoor and outdoor durability: prints maintain their properties over time and resist weathering outdoors.
- Less stringing, no clogging: engineered to cut stringiness and avoid nozzle blocks for consistent results.
- Precise 1.75 ± 0.02 mm diameter: tight tolerance keeps extrusion stable across long prints, compatible with 99% of FDM printers.

What is it good for?
Lampshades and light covers, display cases, vases, fluid-style art, protective covers, functional prototypes and mechanical parts. Transparent Yellow PETG also works outdoors thanks to its weather and chemical resistance. For the clearest results, print slow with a larger nozzle and 100% infill or thick walls.

Good to know
- PETG absorbs moisture over time. If you hear popping or see extra stringing, dry the spool at 60-65°C for 4-6 hours.
- Store sealed with desiccant when not in use.
- PETG sticks firmly to the bed - use a glue stick layer or textured sheet to make part removal easy.
