Filament desiccation
Posted: Thu Jul 10, 2014 3:04 pm
I store my unused filament in a pet food container with an O-ring seal and 750 g of silica desiccant (http://www.amazon.com/gp/product/B003QZ ... UTF8&psc=1). I was curious as to what the relative humidity was like in there, so I put together a wireless data logger and threw it in there:
It appears to equilibriate around 24% RH. You can see the slight inverse relationship between temperature and equilibrium humidity in the graph, the two times I opened the container, and the time my recording process died for some reason.
I've seen Ed Nisley's desiccant experiments on his blog, and his equilibrium humidity ranges much lower than mine, down to below 15%, the limit of his data logger. I'm wondering if I should add more desiccant.
