Note:

Abrasion of the brass nozzle happens quite often when printing PolyMide™ CoPA. A wear-resistant nozzle,such as hardened steel and ruby nozzle, is highly recommended to be used with PolyMide™ CoPA.

PolyMide™ CoPA is sensitive to moisture and should always be stored and used under dry conditions (relative humidity below 20%).

If PolyMide™ CoPA is used as the support material for itself, please remove the support structure before excessive moisture absorption. Otherwise, the support structure can be permanently bonded to the model.

After the printing process, it is recommended to anneal the model in the oven at 80°C for 6 hours.
