[2 LBS] Blue Indicating Silica Gel Beads Desiccants (Industry Standard 3-5 mm) - Reusable Desiccant Beads Silica Beads(Blue to Pink)

The blue desiccant silica gel beads work well to keep things dry. The very distinct color change is very helpful in determining when to re-dry the beads. I mainly use the blue desiccant in my AMS, and I've found I can go a long time before having to dry the beads. The bead size is perfect, with very few small particles that may slip through the desiccant screens or bags. I have completed three dry cycles on this batch already, and the beads are holding up nicely, so durability is not a concern. The bottle makes pouring easy, but I found that pairing it with a 3D-printed screw in a funnel improves the experience and minimizes spillage. There are concerns about the chemical used in the blue desiccant indicating silica gel beads, but I don't handle them often, and the particle size is large enough and heavy enough to not be an airborne concern.

Perfect used in my compressed air dryer. Saves time and money by absorbing water at the central output instead of at each tool instead of needing filters for each tools. Great value that outperforms the desiccant provided with the dryer.

Have ordered this multiple times. Wonderful product! I started using it with my 3D printer filament packed in mylar bags. Worked EXCELLENT. Brought the RH down to <10% within 24 hours and the print quality was dramatically improved, especially on TPU and some of the exotics. Then I tried it in a completely unrelated use case for final drying of basil, oregano, and thyme. Again, I had top notch results. In all this is a high quality product that can be reused many dozens of times and does exactly what it claims.

These silica gel beads change color clearly when saturated, making it easy to know when to recharge. The quart size provides plenty for multiple uses, and they work well for keeping storage areas dry.

Great to replace the old desiccant in my safe and in my filament dryer.

Works, filament is dry. Changes color when they need recharge. Can be dried out in oven. Nuff said.

Works fantastic, before I was using 60grams(20g each) 3 packets inside my filament enclosure and couldn't get below 20%RH after 24hrs, after putting in Dry & Dry, it dropped to 10%RH within 10min. Fantastic. You can see the ambient humidity was in the 40% range. Really works

Started using this in my AMS and the filament has been staying below 10% for weeks without having to run the heater. Good stuff.

Works well as a desiccant for 3D printing filament. I use these beads in an active filament dehydrator with heater, and in a passive sealed bin. With these beads, I very rarely need to power on the dehydrator, which reports humidity around 20% for extended periods of time (months).

Good Desiccant. I use it to keep 3D printing supplies dry.

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.

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.

Perfect for every use
