Storage & Handling

MATERIAL HANDLING AND DRYING: Essentium PCTG-Z is a 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. PCTG-Z 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 600ppm moisture, it should be dried in a low dew point (< -40˚C) oven or vacuum oven at 65 – 70˚C for 4 – 8 hours. Avoid touching filament with bare fingers or introducing oils to the filament prior to printing.
