3D printing material Gembird 3DP-PETG1.75-01-W

Polyethylene terephthalate glycol (PETG) is an amorphous polyester thermoplastic that combines high clarity with good mechanical strength. PETG offers optical transparency approaching that of acrylic while providing impact resistance similar to polycarbonate. It is suitable for a wide range of 3D printing applications and works with many common 3D printers.

Advantages

PETG provides a balance of clarity and toughness, delivering near‑acrylic transparency together with impact resistance close to polycarbonate. The material is easy to print, tolerates a variety of printing setups, and produces durable parts for functional prototypes and end-use components.

Key specifications

• Material: PETG (Polyethylene terephthalate glycol)
• Material type: Amorphous thermoplastic (polyester family)
• Optical properties: High clarity, near acrylic
• Mechanical properties: Good impact resistance, close to polycarbonate
• Compatibility: Works with a variety of 3D printers

How to use

Load PETG filament into a compatible 3D printer and select print settings recommended for PETG: moderate nozzle temperature, heated bed, and controlled cooling. Use proper bed adhesion methods and adjust retraction and print speed to reduce stringing. Post‑processing may include light sanding or polishing to improve surface finish.

Recommendations

For best results, print PETG on a heated bed with a clean build surface, use enclosure or controlled ambient conditions if available, and fine‑tune retraction and cooling settings to minimize stringing and improve layer bonding.
