Indicating Desiccant Canisters
Know when it's time to reactivate these desiccants—they turn from blue to pink when they reach maximum moisture absorption. They are stored in a durable canister.
Aluminum canister has a monitoring window to check for desiccant color change.
Plastic canister is clear so you can see when the desiccant color changes. Desiccant can also be reactivated in a microwave oven. Microwave it for small increments of time and watch for the desiccant color to change.

Rechargeable Small-Space Dehumidifiers
Place these dehumidifiers in small spaces to protect moisture-sensitive materials such as photo lenses or 3D printing filaments. They absorb moisture with a silica gel that changes color, letting you know when they’re saturated. While they don’t need a battery or power cord during use, you do plug them in to dry them out—unlike other desiccants, they don’t require an oven.
Desiccators
Protect material from moisture by storing them in these desiccators. Create a vacuum using the tube connection.
You need both the desiccator and the cartridge, each sold separately. The cartridge has indicating desiccant that turns from blue to pink when maximum absorption is reached.

Dehumidifying Cabinets
Store and protect 3D printer filaments, optical equipment, and other sensitive material in a humidity-controlled environment. Also known as dry boxes and desiccator cabinets, these cabinets prevent moisture-sensitive 3D printer filaments, such as nylon, ABS, and polycarbonate, from becoming brittle, discolored, or broken. They also keep sensitive electrical and optical equipment, such as microscopes and lenses, free from mold and fungus. Their moisture-absorbing desiccants recharge automatically, so you don't have to remember to charge them yourself or worry about the humidity rising unintentionally.
Standard cabinets are sized to store small equipment, such as flasks and lenses, as well as small filament spools. The desiccants recharge every 20 minutes to keep relative humidity below 30%. Although you cannot set the humidity to a specific level, a humidity meter on the door lets you check the reading.
Designed with 3D printing in mind, cabinets with filament feed ports are large enough to hold up to four 12"-dia. filament spools. They also have four filament feed ports, so you can keep filament dry while still feeding a printer, ensuring the filament doesn't go bad in the middle of a longer job. These cabinets can lower relative humidity to less than 20%; set and monitor the level using the analog display.
