Storage & Handling
- MATERIAL HANDLING AND DRYING
Essentium PCTG 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 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.
