Dry & Dry [1 Quart Premium Orange Indicating Silica Gel Desiccant Beads(Industry Standard 2-4 mm) - Rechargeable Silica Gel Beads(2 LBS)

I used this silica gel to keep my 3D printing filament dry. Functionality: It is bright orange when dry and goes a green/grey when wet and then needs recharging by re heating for a period of time (2 hours at 250F /120C or 10mins on defrost in a microwave ) to drive out the moisture. The container is very handy to store it in and keeps it dry until you need to use it. I found the container means you can easily pore the granules into the various filament holders I use. Quality and Durability: It seems to be working well. I have cycled it several times by re drying it in my Bambu AMS dryer and it changes from a greyish green back to orange. The quality seems just perfect for my use. The beads are quite large so if I am in a hurry I can just pour some into the bottom of my filament containers. I have uploaded a video to show the size of the granules and the colour difference between the wet and dry states and the drying instructions on the container. Also a photo of how I store some of my filament in cereal containers and using 3Dprinted spool adapters to hold the beads. I hope this helps you decide if this is right for you.

Does a really good job of drying out 3D print filament. Easy to re-dry in the microwave. Highly recommend.

Does what it says, and my small experiment fits seem to indicate that it can be "recharged". It is cheaper if you buy big 4kg buckets, but how much do you actually need? This item filled up the containers for my 3D printer AMS and containers for 4 multi-spool dry boxes.

Do a fantastic job at keeping filament relative humidity down

Purchased to use with a Bambu 3D printer - have had these in the AMS and also in sealed food containers with part used filament - haven't had a single issue with a print yet and the AMS is reporting a nice low moisture level.

Used these in my AMS for drying filament. Wow! It does it so well. Went from 30% humidity to 10 % in under 12 hours! Going to be buying another so I can dry my spare filaments in their storage containers.

Does what it says on the tin and absorbs the moisture from my AMS box.

seem to be doing what they are supposed to ...Using to keep filament dry

I bought the Dry & Dry orange indicating silica gel beads to help control moisture in a few storage containers and they’ve worked exactly as I hoped. The beads are a good size (not dusty or crushed like some cheaper brands), and the color indicator makes it really easy to see when they’ve absorbed moisture and need to be recharged. I’m currently using them in a couple ammo cans, a camera gear box, and a storage bin in the basement where humidity can fluctuate. Within a day or two I noticed the containers stayed much drier, and the beads gradually started changing color just like they’re supposed to. It’s nice not having to guess whether they’re still working. Recharging them is simple. I spread the beads on a baking tray and put them in the oven on low heat for a while, and they returned to their original orange color. After cooling, they were ready to go right back into use. Being able to reuse them multiple times makes this a much better value than disposable moisture absorbers. The container they come in seals well and makes it easy to store the remaining beads when not in use. Overall, this is a straightforward, effective product that does exactly what it’s supposed to do. If you need a reliable way to control moisture in storage boxes, safes, toolboxes, or electronics cases, these work great.

Purchased for use with Malolos Silica Gel Desiccant containers to keep my troublesome 3D printer filament high, dry and ready for action, after 2 weeks I can say it works great. I've seen major improvements in my PETG prints and even some reduced stringing in some of my PLA+ ones as well. On average it absorbed about 8 grams of water from a ziplock bag sealed filament over the period of 1 week. The colour wasn't all the way green, but I decided to refresh it anyway. Used the lowest defrost setting on my microwave, the silica balls did their best Rice Krispies impression (snap, crackle, pop) for about 2 minutes then it settled down. I let it go a bit too long I think and ended up with about 5 or 6 black crystals due to overheating. So I think in future I will just remove as the popping stops, similar to microwave popcorn, and stir more often, as the recommended 10 minute cook time just seems excessive when using for smaller amounts. I then upgraded my containers to have built-in inexpensive hygrometers, tossed in 45 grams of silica gel, closed the lid, within 10 minutes the humidity of the air near the meter dropped from 45% down to 11% (and eventually 10% after another 5 minutes which I believe is the bottom cap to the hygrometer). As for the jar it came in, the photo can be a bid misleading as it looks like it should be 3-4 times the size bottle which appears similar to a detergent bottle, so it confused me at first when the package arrived and it was much smaller than I thought it would be. But I weight it at just over 2lbs, which was correct, and as I'm only using 45g of silica per-container, I should be able to keep 20 or 1kg filament rolls dry with the single jug (more so if I use the 1/2 size for smaller rolls). The price to keep dry per filament roll is pretty reasonable when you consider they can be refreshed multiple times. Overall, very happy with the purchase, will probably purchase again, and again, and again to support my 3D printing addiction. UPDATED: Perfect cooking recipe for nice orange beads, no burning. 1. Only cook smaller batches if using smaller dishes, larger batches should be done in larger containers with only a layer or 2 of beads to allow for better evaporation. 2. Cook for 2-3 minutes at a lower power setting, I use powerlevel 3. 3. Stir to release the steam. 4. Cook for 5 minutes at power level 2 to maintain the temp, but not burn the beads. 5. If beads are mostly orange, then you're done, if still greenish repeat step 2 through 4. Suggest weighing beads before and after.

Great, ReUsable!!

No funcionó como esperaba. Suponía que podía capturar humedad del ambiente y podría después desecarlo, que de nuevo se pondría anaranjado, pero se quedaron negras las perlas

What i ordered is what i got , very happy
