Fiberon™ PET-GF15 is a high-performance 3D printing filament that combines the strength of glass fiber with the user-friendliness of PET. This material has been specifically developed for makers and professionals who need more strength, stiffness, and heat resistance than standard PETG – but without the complexity of technical high-performance polymers.

With a matte, high-quality finish, excellent dimensional stability, and improved mechanical properties, PET-GF15 is an ideal choice for functional parts and industrial applications.

✅ Features & Benefits

• PET + 15% glass fibers – increased stiffness, strength, and dimensional stability

• Excellent chemical & moisture resistance – ideal for demanding environments

• High dimensional accuracy – minimal deformation during and after printing

• Clean, matte surface quality – smoother than many other fiber-reinforced materials

Key Features

• Exceptional stiffness and strength
• High heat resistance up to 133 °C after annealing
• Minimal warping and stable dimensions
• Smooth, professional surface finish
• Compatible with AMS and multi-material systems
• Prints up to 250 mm/s with the right settings

Product Overview

Fiberon™ PET-GF15 offers a perfect balance between strength and printing ease. The glass fiber reinforcement significantly increases flexural strength without making the material harder to process. This creates a filament that is stronger and stiffer than PETG, yet remains easy to print on most (semi-)enclosed 3D printers.

This makes PET-GF15 ideal for makers who need a durable, accurate, and heat-resistant material for truly functional applications.

💪 Mechanical & Thermal Performance

• Flexural strength: approx. 104 MPa

• Heat resistance: up to 133 °C after annealing

• High stiffness due to glass fiber reinforcement

• Very low shrinkage and deformation

PET-GF15 maintains its shape and dimensions, even after heat treatment. This makes the material suitable for precise parts that need to remain dimensionally stable under load.

Perfect for situations where structural integrity is essential.

🖨 Printing & Processing

Despite the glass fiber reinforcement, Fiberon™ PET-GF15 prints surprisingly smoothly.

Recommended settings:

• Nozzle: 280–310 °C

• Bed: 70–80 °C

• Cooling: off or minimal

• Keep dry: below 20% RH for optimal results

Important:
Always use a hardened nozzle (e.g., hardened steel, ruby, or carbide).
Glass fibers are abrasive and will wear out standard brass nozzles quickly.

Annealing is optional, but recommended for parts exposed to temperatures above 80 °C.

🎨 Surface Quality & Compatibility

Compared to many other fiber-reinforced materials, PET-GF15 has a very clean, matte surface with less visible fiber structure.

Furthermore, it is suitable for AMS and other multi-material systems, ensuring that workflows with multiple colors or materials run smoothly.

🔩 Applications

Suitable for sturdy, functional parts that must withstand long-term mechanical stress or heat, such as:

• Automotive parts

• Brackets, mounts & holders

• Machine and tool components

• Housings and protective covers

• Industrial functional components

• Functional prototypes

Conclusion

Fiberon™ PET-GF15 is the perfect choice for anyone looking for:

• more strength than PETG,

• better heat resistance,

• minimal warping,

• and a high-quality, neat finish.

A powerful material that bridges the gap between standard PETG and technically advanced engineering polymers – without extra complexity.
