[Guide] How to easilly recover wet filament

In this short post we try and see how  to recover wet filament. Don’t despair! Nothing is lost. Your filament can be saved, and as usual we will provide you with more than one solution!

Recover wet filament: First solution

The first and “most professional” solution is the purchase, at an affordable price, of a domestic dryer for fruit and vegetables.

This accessory can be purchased in the most popular electronic markets for less than 40 €, as well as in almost all supermarkets. Look here on Amazon
If you buy a model similar to the one shown in the photo, just make a cylinder of the right size in very thin plexiglass (as in our case) or even cardboard, for a height of about 30 cm.
In this way you can dry up to 3 coils.  It is set to 55°/60° for 24 hours, and you can be sure that you have eliminated all the moisture absorbed.

However, if you are cheap, or do not want another accessory for the home (under penalty of divorce) but still want to dehumidify your coils, don’t worry! You can use your home oven, just as it was done to remove moisture from silica gel or rice.

Recover wet filament: Homemade method

This time the parameters change a little but the temperatures must be 55°/60° in case you want to dry the PLA and 70°/80° in case of other materials. Also the timing will change, in fact the exposure will be of 6 hours at least, up to 12 hours in the most desperate cases. Also in this case, the oven door must be kept slightly open to allow moisture to escape.
This method is generally more dangerous for the filament, and requires (especially for the PLA) an oven with high temperature accuracy. In fact, this material heated to 70° starts to melt and you will never get away with it if will becomes a shapeless mass. To be safe, keep it a few degrees lower, increasing the exposure time by a minimum of 8 hours.

Of course, if you often get wet filament coils you are doing something wrong with storing the material. In this regard, read the guide on how to best preserve the thermoplastic materials. To be applied slavish especially for the preservation of hygroscopic materials such as Nylon, PVA and others.
