3D Filament production

Hello, I am producing 3D filament in Azerbaijan, but I am experiencing problems during production. Can you help me?

Can you provide more details on what your problem is?

Hello. I produce filament, the PLA and Petg I produce remain wet after production. Customers are not satisfied. How can I protect materials from getting wet? I dry raw materials in special drying equipment before production. I just can’t get the dryness I want. Maybe I don’t know if it was necessary to use special additives during production?
