THINGS TO KEEP IN MIND
- TPU is a material prone to absorb moisture. When this happens, the filament can make bubbles or creaks when printing.
- To remove moisture, you can use any of the following strategies:
- Leave the filament in a closed room with a dehumidifier for 24 hours.
- Place the filament in an oven for 2 hours at a temperature of 60°C.
STORAGE & PRESERVATION
- Filaments tend to absorb moisture from the environment, leading to problems during printing or finishing. For this reason, it is important to keep the relative humidity value between 10-15%.
- Moisture may cause the filament to degrade, clogging the extruder and varying it’s physical and mechanical properties.
- To keep the filament in good condition and preserve its aroma for as long as possible, it needs to be stored and dried correctly.
- The filament must be stored in airtight containers, preferably vacuum packed. You can use zip bags with silica gel beads, vacuum-sealed bags or food containers with a vacuum seal.
- There are many techniques to remove moisture, including:
- Conventional methods such as drying the filament in a home oven or a food dehydrator. At low temperatures for long periods of time.
- Professional ways such as using a filament dryer.
- The useful life of a filament can vary according to different factors. That is why it is important to follow the manufacturer’s recommendations for drying and storage parameters.
