PolyMax™ PC

PolyMax™ PC is an engineered PC filament combining excellent strength, toughness, heat resistance and printing quality. It is the ideal choice for a wide range of engineering applications.

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.

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)
