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)
