Storage & Handling
- MATERIAL HANDLING AND DRYING
Essentium TPU 74D is a very hygroscopic thermoplastic and will rapidly absorb moisture from humid air. Keep the material in the vacuum sealed packaging until you are ready to print with it. TPU 74D 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 200ppm moisture, it should be dried in a low dew point (< -40˚C) oven or vacuum oven at 90 – 120˚C for 2 – 3 hours.
