HOW DOES MOISTURE SENSITIVITY IMPACT TPU-FLEX?
TPU-FLEX is a hygroscopic material. This means that it attracts moisture from the air which can have a negative impact on the printing performance. After printing, it is strongly recommended to place the spool into a vacuum bag (without any silica*) for storage.
* More often than not silica gel sachets contain a higher ppm moisture content than the filament itself which would have a reversed effect.

WHEN IS TPU-FLEX TOO WET TO PRINT?
If the TPU-FLEX is too wet, this can be evaluated visually:
1 - Heat the nozzle to the preferred temperature for your printer.
2 - Extrude or push the filament through the nozzle.
Tiny bubbles appearing when the filament is coming out of the nozzle indicates expanding moisture and can cause unwanted printing effects.
When a clear filament is not perfectly clear after extruding, and has milky white streaks through it, it is also too wet to print.

WHAT TO DO WHEN TPU-FLEX IS TOO WET TO PRINT?
TPU-FLEX attracts moisture. After everyprint it is recommended to dry the filament before the next print.
The formula for drying TPU-FLEX is easy:
-After a 24 hour print put it into a standard heated air oven or filament dryer at 65°C for 24 hours.
-After a 8 hour print, put the filament into the oven for 8 hours.
-After a 2 hour print, put the filament into the oven for 2 hours.
This will be enough to dry the TPU-FLEX to moisture levels in order to have the best printing results.
