Activated Alumina Desiccant Beads for 3D Printer Filament Reusable (2lb)

I’ve been very impressed with the Slice Engineering 2lb Activated Alumina Desiccant. It arrived quickly and the container makes it easy to pour and refill smaller holders without making a mess. Compared to orange indicating silica gel, this absorbs more moisture and seems to last longer before needing to be recharged. The tradeoff is that it does not change color, so you will want to monitor humidity levels with a hygrometer rather than relying on visual indication. I use this in 3D printed spool desiccant containers and in my AMS desiccant holders, and it has worked extremely well. Humidity stays low and filament performance has been consistent. To recharge, I dry it in my AMS HT using a high temperature safe container at full temperature for a couple of hours, and it is ready to go again. If you want a higher capacity desiccant solution for filament storage, this is a great option and I would definitely recommend it.

Quite a few reviews saying the package wasn't full, but mine was filled to the brim - I think they got that fixed. It's nice stuff, I really enjoy the infinite re-usability and the performance over traditional desiccant packs. I'm including a photo of the 2 lb package next to a Bambu AMS so you can get a sense of the size.

I switched to activated alumina for my 3d printing needs and don’t regret it. Sure it’s more expensive than silica per pound, but this stuff works really well, and I find it keeps moisture levels lower for a lot longer than silica did. There’s no color change to indicate it’s time to dry it out, but I’m running a hydrometer for that. I don’t have to worry about the toxicity of the chemical makeup when cooking off the moisture to recharge like I did with silica. I ended up buying a second 2lb bottle, as one contained a little more than what fills up all the dry pods in my BambuLab AMS + 4x reel pods. So now I can dry/recharge a batch ahead of time and swap it out quickly to minimize the time it’s exposed to the open air.

This stuff works very well! It lasts for a couple months or more during the hot summer months. Used in AMS.Can be recharged easily in a toaster oven without concern of poisoning yourself like indicating Silica.

When I ordered my 3d printer I did some research on traditional Silica Beads and Alumina Desiccant Beads and I really like the Alumina Beads as they really seem to absorb the moisture well. I live in a humid area of the country and I can get the moisture in the AMS enclosure for my printer down to around 13 percent using this stuff which I printed containers to hold it and put in the AMS Unit. And I can get the moisture down in the 20s in the Cereal containers that I use to store my filament.

works really well for keeping my 3D filament dry. Much better than the silica that I was using. 10% humidity versus 27%. The only complaint I would have is the cost, 2 lbs of this where I could buy 6lbs of another brand for about the same price. I am still testing out the differences between the brands but so far it looks to be the same. I will pay more for American made products but not 3 times the price.

Substantially better than silicone dessicant. Absorbs more (don't know about the 10x) but maintains dry boxes substantially longer for 3D printing filaments. Yes it is reusable. No it doesn't change color but do some research, silicone dessicant alone isn't a heath concern but the chemicals use for the color change are very toxic. Just get a simple hydrometer and problem solved.

I just got my X1C couple months ago and learned about this keeping filament dry thing recently. I only print for personal use which is not often enough to justify buying a dryer in my opinion which would also take up more space in my home office, so I opted for the route of getting more desiccant that can recharge. It's been quite humid recently in LA, and with the AMS closed most of the time with bunch of desiccant packs, it's been about 35% humidity and the app shows C or D which is not ideal and it worries me since I've been seeing more stringing recently. It started raining yesterday, so I printed the desiccant boxes for the AMS and got this item with overnight shipping. I put them in the machine sometime early this afternoon, and slowly I can see my hydrometer number keeping going down once I placed everything in the AMS :) It's been not even 10 hours, and I opened the box couple times changing filaments, the Bambu studio shows it's "B" and my hydrometer shows 10%, X1C screen shows the AMS is 19%. Either way, it's way better than 30+ prior and I'm very happy about it. So far so good, easy to fill, I don't see any powder/residue when I pour into the boxes. Yes it's a little more than the silicone stuff but this works amazing and it's also rechargeable. I'm glad I gave this a try :)
