Dry & Dry 1 Quart Blue Replacement Desiccant Indicating Silica Gel Beads - 2 LBS Reusable by

Perfect for every use

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).

I use this for my bambu p1s printer I printed fitted containers for the ams and with this product no issues with damp inc. the lustre filament that needs to be dry

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.

5 stars

I purchased two containers of blue indicating silica gel to support my 3D printing setup, and they've proven to be highly effective. I use them within the Bambu AMS unit to maintain optimal humidity levels for my filaments, as well as inside custom-printed containers placed directly in open filament spools. The beads consistently help keep humidity low, as confirmed by hygrometer readings. One of the standout features is the color-change indicator, which clearly signals when the beads are saturated. Recharging them is simple—just a quick cycle in the microwave—and they’re ready to use again. The reusability and ease of maintenance make this product a practical and reliable solution for filament storage. Highly recommended for anyone looking to protect their materials from moisture.
