Gembird 3DP-PETG1.75-01-GR 3D Printing Material

PETG (polyethylene terephthalate glycol-modified) is an amorphous polyester thermoplastic that combines optical clarity with mechanical strength. It is suitable for a wide range of 3D printing applications where a balance of transparency and durability is required. PETG offers clarity close to acrylic and impact resistance similar to polycarbonate, while remaining easy to print on many consumer and professional 3D printers.

Advantages

PETG provides a clear surface finish with good toughness and impact resistance. It is less brittle than acrylic and easier to process than polycarbonate, offering reliable layer adhesion and low warping in typical printing conditions. The material prints well on a variety of FDM/FFF 3D printers and works for both functional parts and transparent or translucent prototypes.

Key specifications

• Material: PETG (polyethylene terephthalate glycol-modified)
• Type: Amorphous polyester thermoplastic
• Optical properties: Clarity close to acrylic
• Mechanical properties: Impact resistance comparable to polycarbonate
• Printability: Compatible with a variety of 3D printers; easy to print

How to use

Prepare your model and slicer settings according to standard PETG recommendations: moderate nozzle temperature, heated bed, and controlled cooling. Use good bed adhesion methods and calibrate extrusion to avoid stringing and blobbing. Print at speeds appropriate for your printer and filament diameter, and allow parts to cool before post-processing. Follow printer manufacturer guidance for best results.

Recommendations

Store PETG filament in a dry, cool place to prevent moisture absorption. For transparent or high-clarity prints, use clean nozzles and slow, consistent printing settings to minimize surface imperfections.
