Dry & Dry [3.6 LBS] Blue Indicating Silica Gel Beads Desiccants (Industry Standard 3-5 mm) - Reusable Desiccant Beads Silica Beads(Blue to Pink)

I’ve been using the Dry & Dry [2 LBS] Blue Indicating Silica Gel Beads Desiccants (Industry Standard 3-5 mm) as my go-to desiccant for the Bambu AMS, and it’s been a solid addition to my 3D printing setup. Living in a humid area, keeping filament dry is a constant battle, and these reusable silica beads have made it a lot easier to win that fight.The 2-pound jug is a perfect size for my needs—enough to fill multiple desiccant holders in the AMS without feeling like I’m rationing it. The beads are about 3-5 mm, which makes them easy to handle and pour into breathable bags or containers without spilling everywhere. I love the blue-to-pink color change feature; it’s a clear, no-guesswork indicator when they’ve absorbed enough moisture and need a recharge. In the AMS, they start off a vibrant blue, and over a couple of weeks, they gradually shift to pink as they soak up humidity from the filament spools.Performance-wise, they do the job well. Paired with a hygrometer in the AMS, I’ve seen humidity levels drop from the 40-50% range down to a steady 15-20% within a day or two, depending on the weather. That’s been a lifesaver for my PLA and PETG prints—no more stringing or brittle parts due to moisture. The fact that they’re reusable is a huge bonus. When they turn pink, I pop them in the oven at 225°F for about an hour (spread out on a tray), and they’re back to blue and ready to go. I’ve also tried the microwave defrost method for 10 minutes, which works in a pinch, though it’s a bit less consistent.The build quality feels reliable—the beads don’t crumble or turn to dust, even after a few recharge cycles. The jug itself is sturdy with a tight lid, keeping the unused portion fresh until I need it. One small quirk: the color change isn’t always uniform across all the beads, so some stay blue longer than others, but it hasn’t affected their overall effectiveness. Also, they’re not the fastest at absorbing moisture compared to some pricier options, but for the price and reusability, I can’t complain.For anyone running a Bambu AMS, these silica beads are a practical, cost-effective way to keep filament in top shape. They’re simple to use, easy to recharge, and have kept my prints smooth and consistent. Definitely a worthwhile pickup for any 3D printing enthusiast dealing with humidity woes.

I loved it, very useful and dries very nicely. It works very well in the microwave to re-dry it too. Would recommend, well worth the money

Purchase this to use with my 3-D printer filament. It is works great and is re-chargeable so you can reuse it multiple times. I highly recommend. Color change and durability is great!

Works as intended. Keep my filament nice an dry. When they turn pink I pop them in the microwave and there nice and blue again!!

Very effective product to reduce moisture and can be reused.

Absorbs moisture very well.

I bought this to keep my printer filament dry and to put inside my bambu AMS system it works phenomenally well. Keeps the humidity low and the color change to tell you its saturate is easily noticeable and recharging it is extremely easy! I just throw it in the oven and boom all set. Highly recommend.

I tried using cheap desiccant packs that didn't work very well. These gels keep the humidity ridiculously low and do a great job. My filament enclosure stays about 10% humidity with these.
