Which is to say, not very far on this at all but I think I have a good idea on how have my cake and eat it too for desiccant for my spools.
I am finding I can’t get the humidity below about 50% in my AMS and the silica I am using needs constant refreshing.
Well it seems there is stuff called activated alumina that is pretty good and honestly about the same costs as silica beads, but I need to be able to put it in the oven to refresh it. Which doesn’t work well with my 3d printed desiccant holders.
Insert, cheap tea strainers.
It seems I can get ones that are 4cm in width by 6cm in height that are made out of stainless steel that I can actually put straight in the oven.
So, I am working on getting the parts and items but was wondering if anyone else has done this or have any suggestions before I start grabbing stuff?
Why does your silica need constant refreshing? Has it always been that way? Perhaps you have a moist reel or two in there that need a good cook off in a filament dryer. I would look for more root cause for the humidity issue rather than hope another desicant will be a Gosend. Silica is pretty good stuff, I think you may end up dissapointed with this strategy.
Probably got a wet filament but they are all new and I have tried to give them a quick run through the dehydrator I have which is part of the goal of getting a better desiccant.
Also it’s like 80% humidity where it prints so at 45% it’s not a small amount reduced.
Also, silica is fine but there are other desiccants. Holding onto the past cause it’s good enough never explores if there is something better.
