Replacing the AMS Desiccant

Community Contributions

It is very important to replace the AMS desiccant material as often as needed, and to check it every two weeks to confirm it if it is still usable.

If the desiccant is used up, please replace it in time. If the desiccant is not replaced for a long time, it will lose its ability to absorb water, thus losing its ability to protect the dried filament.

In addition, when it is not replaced for more than 3 months, the desiccant may also leak water, short-circuit, or damage the circuit or electronic components inside the AMS.

The following Wiki articles show the process of how to do it.

If anyone is interested, this is called deliquescence and it’s a property of some chemicals - they absorb so much water from the air they eventually dissolve in the absorbed water and can make a big mess because they make corrosive liquids. But they are great desiccants that keep working and working.

I don’t let mine get above 2 before changing them out.
