Experience superior surface texture and stiffness with PET-CF17, the high-speed 3D printing material that delivers strength without moisture sensitivity concerns. This carbon fiber reinforced filament excels at rapid prototyping, offering exceptional print quality and dimensional accuracy. Combining the best of strength, speed, and surface finish into one exceptional composite filament.

What is the percentage of the carbon fiber content in Fiberon™ PET-CF17?

It contains 17 wt% carbon fibers.

Do PET-CF17 prints need annealing? What are the annealing conditions? Will deformation occur?

We strongly recommend 100°C, 10h annealing to achieve the best performance of the material.

To avoid deformation of the prints during annealing, please pay attention to the following:

1. Before returning 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.
2. During annealing, do not touch the sample with your hands or apply any additional load to the sample.
3. During annealing, ensure that the temperature in the oven is uniform and there are no obvious obstructions that cause uneven temperature of the sample.
4. 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.
5. 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.
6.  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.
