What is annealing?

Do I have to anneal my PET-CF17?

Annealing significantly improves the heat resistance of PET-CF17, raising its heat deflection temperature (HDT) from around 70°C to over 100°C. However, in terms of mechanical properties, annealing mainly increases the stiffness (modulus) of the material but does not enhance impact resistance or layer adhesion. This means the material does not become tougher after annealing.

Annealing at 120°C is deforming my part, what should I do?

If your part has very thin sections - 120°C annealing can cause issue with deformation. In this instance we would give these three potential solutions

1. Gradual heating method. Divide the annealing process into two stages, first keep the temperature at 80-100°C for a period of time, and then slowly heat it to 120°C to avoid rapid heating and internal stress concentration.​

2. Anneal at a lower 100°C for a longer period of time. If annealing is performed at 80-100 degrees, the crystallization rate of PET-CF is very slow and the ideal mechanical properties cannot be achieved. 100°C would be the bare minimum to anneal PET-CF at. Our suggestion would be to try 14 hours though we do not have a strict standard for this at this time.

3. Keep support material on thin sections with large overhangs. You can also use other things such as salt or sand to tightly compact around your print to help prevent deformation.

Will the spools work in an AMS?

Yes! We have redesigned the edges of our spools so all Polymaker products will now spin great in the AMS.

That said - you will need to be careful when using any abrasive materials in the AMS.

What is the difference between PET and PETG?

PET and PETG differ in their chemical structure, properties, printability, and applications. PETG is more flexible, easier to print, and suitable for 3D printing and medical applications, while PET is more durable and suitable for applications requiring thermal resistance.

Do I need a filament dryer?

It is possible to print this without a filament dryer, but that can depend on the environment where you live. If you live in a humid climate - you may need a filament dryer either entire time while printing, or at least between prints. Keep stored dry.

Can you offer 1KG Fiberon™ Spool Options?

Unfortunately we are not offering 1KG Fiberon™ options and this has to do with the increased chance of carbon fiber and glass fiber filament snapping on the spool.

Since carbon fiber and glass fiber filament is more brittle, we spool these with a larger core. This larger core means that 1KG of filament will not fit on a 1KG spool.
