PETG-GF Filament – Glass Fiber Reinforced PETG for Stronger Prints

3D Printing Canada’s PETG-GF (Glass Fiber Reinforced PETG) builds on the reliability of standard PETG by reinforcing it with glass fibers for increased stiffness, dimensional stability, and heat resistance. It’s ideal for users who need stronger, more rigid parts without moving to difficult-to-print engineering filaments.

The glass fiber reinforcement reduces flex and creep while helping parts maintain their shape under load. Compared to regular PETG, PETG-GF offers improved rigidity, better resistance to deformation, and more consistent results on larger or functional prints.

Despite its added strength, PETG-GF remains easy to print and produces minimal odor. It resists warping, offers excellent layer adhesion, and delivers reliable performance for demanding applications where standard PETG may fall short.

From brackets and mounts to enclosures and functional components, PETG-GF is a smart choice for parts that need added stiffness, strength, and long-term durability.

Why Choose PETG-GF

• Glass fiber reinforced for increased rigidity and strength
• Improved dimensional stability over standard PETG
• Reduced flex and creep under load
• Low warp & low odor compared to ABS
• Easier to print than most engineering-grade materials
• Excellent layer adhesion for strong, functional parts

Printing Guidelines

• Nozzle Temperature: 230–250°C
• Heated Bed: 70°C
• Warping: Minimal
• Shrinkage: Low

Ideal Applications

• Structural and load-bearing parts
• Brackets, mounts, and fixtures
• Enclosures and housings
• Functional prototypes
• Parts requiring higher stiffness than standard PETG

If standard PETG isn’t stiff enough, PETG-GF is the upgrade. It delivers enhanced strength and stability while maintaining the printability and reliability that makers expect from 3D Printing Canada filaments.
