PET-G (Polyethylene Terephthalate Glycol)

Thermoplastic Polymer

PET-G for FDM 3D Printing

PET-G is a 3D printing filament thst combines PLA’s ease of printing with strength and durability similar to ABS.

It is made by modifying PET with glycol, which enhances its toughness and reduces brittleness. PET-G offers good chemical resistance, flexibility, and impact strength, making it ideal for functional parts and prototypes.

It also has excellent layer adhesion and is less prone to warping, requiring no heated enclosure.

Key Benefits

PETG is a strong, flexible, and chemically resistant thermoplastic that offers great printability, minimal warping, and a smooth finish.

Impact Resistance

Consistent flow and minimal warping make it ideal for everyday use.

Flexibility

Less brittle than PLA or ABS, with slight flex for added durability.

Great Layer Adhesion

Prints with strong interlayer bonding and minimal warping.

Food-Safe Options

Available in certified grades suitable for food contact when printed properly.

Heat-Resistant

Withstands temperatures up to around 80°C without deforming.

Glossy Finish

Produces prints with a smooth, glossy surface right off the printer.
