Storage & Handling

MATERIAL HANDLING AND DRYING: Essentium PET-CF is a slightly hygroscopic thermoplastic and will absorb moisture from humid air. Keep the material in the vacuum sealed packaging until you are ready to print with it. PET-CF filament should always be fed to the printer in a dry container and stored in a dry cabinet. If the material does absorb more than 50 ppm moisture, it should be dried in a low dew point (< -40˚C) oven or vacuum oven at 90˚C for 6 – 8 hours. Avoid touching filament with bare fingers or introducing oils to the filament prior to printing.
