Does PolyMax™ PC need to be annealed?

Annealing is the process of heating up the printed parts at a certain temperature for a certain period of time. You can anneal PolyMax™ PC at 90˚ for 2h.

The purpose of annealing PolyMax™ PC is to release the internal stress which accumulates during the printing process. This internal stress can creates micro cracks over time and weaken the part.

(NOTE: In the case of semi-crystalline polymers such as Nylon, annealing purpose is mainly to crystalize the material for better mechanical and thermal properties)Does PolyMax™ PC need to be annealed?

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.

Does PC absorbs moisture?

The short answer is yes, PolyLite™ PC will absorb moisture slightly faster than regular PLA. We recommend using a dry box to achieve high quality and strong prints.

Why are my parts cracking along layer lines?

You really need to make sure you are using an enclosed printer and that you are keeping ambient air temps as high as possible. You then want to make sure you are annealing the part the moment the print finishes. Keeping ambient air temps high and allowing for very slow cooling is a great way to reduce chances of cracking and to maintain layer strength.

What is the best surface adhesive for PolyMax™ PC?

In our experience we had excellent experience with Magigoo PC. This special glue allows great adhesion when the build plate is hot and easy release when the build plate cools down.
