Filament Drying Desiccant (2 lb) by Slice Engineering | 10X More Powerful Than Silica Gel | Infinitely Rechargeable | Prevent Wet Filament | Fits Perfectly Inside Spools | Made in The USA

This is a very good desiccant, as far as it goes. The color change is obvious making it easy to know when to change/renew it. It renews very well as far as I can tell, but I’ve only renewed it three times so I can’t comment on how many renewals it will tolerate.The only negative is that it seems to have a lower limit of about 10%RH. I put this in with the filament spools I dry to try to keep moisture out after the dryer runs for 8-10 hours. It seems to work fine, helping to keep the filament dry.

I used 4/5 of the 2lb bottle to fill my ams and all 4 spools and went from 26% to 6% in 8 hours. I did not bake it first.

Amazing desicant! I am able to keep the moisture down to 10% in my filament tote.

This really dries out well, I'm just docking a star because when I first poured it into my desiccant containers, it brought the RH down to 20%, and I thought it was as good as it got, but I was wrong, it was partially saturated already. I put it in the oven to recharge for the first time, and now it's back in the dessicant containers and got the RH all the way down to 8%. Wish it performed out of the box like this and didn't require me to bake it to get the best performance. Otherwise good.

This stuff is way better than the color changing desiccant that you're used to. In a polydryer, the lowest humidity i would see was 15%. Never went lower. With this, I've seen 9% and I'm sure it would go lower. 2lbs is quite a bit as well, and it's reusable. So that's a plus.

Definitely worth the extra cost. Put this in my Bambu AMS and it's keeping RH around 9%. Silaca won't do that or last as long. Definitely buy again. I haven't cooked it yet. Seems weird, but sounds like that'll be a while before I have to do it.

Love this stuff, just wish it was less costly.

it just works as expected
