Are you looking to buy Polymaker Fiberon PET-GF15 1.75mm Filament 1kg in Australia?
Fiberon™ is polymakers family of fibre-reinforced composite filaments developed to provide outstanding mechanical performance for a range of engineering applications.
Fiberon™ PET-GF15 combines PET with 15% glass fibre reinforcement to deliver exceptional stiffness, dimensional stability, and thermal resistance. It’s engineered for users who need the toughness of an engineering-grade filament without sacrificing printability.
Features
- Industrial-Level Performance, Everyday Usability - With a bending strength of 104 MPa and HDT up to 133°C (0.45MPa, after annealing[1] ), PET-GF15 withstands high stress and high-temperature environments where other materials would deform. It prints easily on most modern FDM printers, even at speeds up to 250 mm/s.
- Excellent Surface Finish & AMS Compatible - Achieve smooth, professional-grade prints with a refined texture that minimises visible layer lines. Fiberon™ PET-GF15 works seamlessly with most multi-material systems.
- Dimensional Stability & Low Warping - PET-GF15 maintains consistent accuracy and minimal warping, even on large projects. After annealing, in a wide range of cases, the dimensional change stays below 0.5 %, ensuring tight tolerances for functional parts that demand reliability and precision. Warping during annealing can be likely for wide flat surfaces, or thin models without ribbing.
[1] Fiberon™ PET-GF15 displays the best mechanical and thermal properties when fully crystallized. The printed part will not reach full crystallization during the printing process, an additional step is required: Annealing. PET-GF15 can be annealed in the oven at 120˚C for 16 hours. Note for some geometry annealing may not be recommended. Please see settings & specifications tab for detailed annealing instructions.
Physical Properties
All PET-GF specimens were printed with 300°C nozzle temperature, 80°C bed temperature, cooling fan OFF and were printed with 100% infil, 2 shells and 3 top & bottom layers.
All samples were annealed after printing at 120°C for 16h.
PET is a semi-crystalline material, it's crystalline regions offer many properties, but in particular their structure deliver the heat resistance that nylon is known for. Annealing after printing is a critical process to achieve consistent crystallinity and complete the production process of PET parts.
Mechanical Properties
Data taken from Polymakers Technical Data Sheet and is intended for reference and comparison purposes only. Due to the nature of 3D printing, data should not be used for design specifications or quality control purposes.
Printing Settings
- Nozzle Temperature: 280°C - 310°C
- Build Plate Temperature: 70°C - 80°C
- Enclosure: Recommended
- Chamber Temperature: Room temperature is suitable.
- Cooling Fan: OFF for better strength
- Printing Speed: Up to 250mm/s
- Retraction: The ideal retraction settings vary from printer to printer and depend on the hot end. The following settings have been a good starting point for many machines.
- Direct Drive: Retraction distance of 1mm with retraction speed of 20mm/s
- Bowden: Retraction distance of 3mm with retraction speed of 40mm/s
- Recommended Support Material: PET-GF15 is compatible with PolySupport for PA12
The above are printing recommendations based on 0.4 mm nozzle. Please note ideal printing conditions may vary depending on your 3D printer setup. For high speed 3D printers, make sure to use a suitable printer and increase your extrusion temperature in order to use higher printing speeds.
Hardened nozzles such as hardened steel are less conductive than brass, so depending on your 3D printer, printing with a higher extrusion temperature may be required when using a wear resistant nozzle.
We highly recommend to use a wear resistant nozzle when printing Fiberon™ PET-GF15. Hardened steel offers much better wear resistance than brass. The second consideration it to keep PET-GF dry during printing and storage. See "Storage and Drying" details below for instructions to protect Fiberon™ PET-GF15.
Annealing Fiberon™ PET-GF15
For best dimensional accuracy, it is recommended to use Fiberon™ PET-GF15 directly without annealing in cases where temperature resistance of PET-GF15 above 80°C is not required.
For the best mechanical performance it is highly recommended to anneal parts printed in Fiberon™ PET-GF15. Annealing is the process of heating up the printed parts at a certain temperature for a certain period of time. Fiberon™ PET-GF15 displays outstanding mechanical and thermal properties when fully crystallized. The printed part will not reach full crystallisation after the printing process and annealing is required to complete this step.
We strongly recommend 120°C, 16h annealing to achieve the best performance of the material. To avoid deformation of the prints during annealing, please pay attention to the following:
- Before annealing the prints, please confirm that the prints have been printed for more than 24h, or placed in an 80-degree oven for 2h to eliminate the internal stress after printing.
- During annealing, do not touch the sample with your hands or apply any additional load to the sample.
- During annealing, ensure that the temperature in the oven is uniform and there are no obvious obstructions that cause uneven temperature of the sample.
- For prints with a bridge length of more than 3cm, or a thick layer on the upper part of the bridge; prints with large overhangs or small overhangs; all need to add supports and anneal in the oven together with the supports.
- For thin-walled areas with a wall thickness of less than 4mm, you can try to add reinforcing ribs or increase the wall thickness to avoid possible annealing deformation.
- In principle, the sample placement method needs to be consistent with that during printing, and it is best to enter the oven directly together with the base plate.
- The colour of the printing parts will become slightly lighter after annealing due to the change in crystallinity, which is a normal phenomenon.

Compatibility
Fiberon™ PET-GF15 has been engineered so users can print strong glass fibre filled parts on a wide range of 3D printers. As the glass fibre in this material is highly abrasive we recommend customers first check that their 3D printer is equipped to print abrasive materials before purchasing this product.
Aside from wear resistance, there are a few important considerations for this material that we recommend.
To get the best mechanical and thermal properties out of this material, annealing is strictly recommended. Please read information further above regarding annealing steps.
Reinforced filaments tend to be much stiffer than other standard filaments and this can cause problems when passing the filament through a printer’s feeding system. For a steady and uninterrupted flow of filament, it is recommended to take extra care and make sure your filament guide system is smooth and with minimal bends. Brass nozzles give a better thermal conductivity than hardened nozzles such as stainless steel. Depending on your 3D printer, printing with higher extrusion temperatures may be required when using specialty nozzles to ensure the correct extrusion temperature is achieved.
Of course with thousands of unique 3d printer models on the market, we can't guarantee each filament type will work with every 3D printer. Slicer experience and setting adjustment is always required to get the most out of a material. Before jumping into an ambitious project we always recommend printing some known calibration tests to build or make adjustments to the filament profile.
