Which filaments should be dried

Hi,

I think it may be interesting to show as a problem to dry or not filament and which one was already mentioned. They made some tests.

@kamil1 The short answer is “All of them”. With very few exceptions, all filament absorbs water. The ones that do not are not currently approved for use with the Robox, so you use them at your own risk.

@bhudson, my point in this post was not to tell/show people which filament should be used or not. Just, previously there was a discussion on the forum if it is necessary and which filament should be dried or kept in as dry condition as possible. Moreover, how long this process takes. The dry process itself and after to make it wet again. Based what it is in this blog, it seems that it should be dried every 2 days to keep optimal, best condition. Just I thought that it can be interesting…I found it in this way.

@bhudson Generally and a few years ago you’d be correct, but there has been a spate of hydrophobic polymers introduced recently, including hydrophobic PLA, and I use a hydrophobic PET-G which has been consistently good. Both of these are not outside any material temperatures specified with the official SmartReel versions used with Robox printers, and being no more abrasive are definitely not warranty busters, so folks there is no risk. 🙂 Some of the modified bioPCs and ABSs are even lower temperature (bed and nozzle) compared to SmartReel offerings, so will be less strain on the seals.

@kamil1 interesting article, because you’d never expect a filament to be too dry!
