Trustleaf 1kg Tub of Orange Self Indicating Silica Gel, 2-4mm Beads - Dehumidify - Flower Drying - Storage

Does the job nicely. I use it to keep my 3d printing filament nice and dry. Last about a month before I have to dry it. Super simple to use as you can see the colour changing when it needs drying. Compared to the sachets this is a great value for money and much easier to dry and reuse.

The Trustleaf orange silica beads are a great way to take moisture from whatever you need to dry out. Trustleaf sell this for drying out Flowers, but it has many other uses such as 3D printing filament or photographic equipment, telescopes or lenses of any kind, this silica gel is perfect for the job. As it absorbs moisture, it changes colour from orange to dark green, when it has changed colour, you can put it in an oven to "re-charge" it, or dry it out. Then just use it over and over.Instructions are printed on the tub for temperature and time it takes, you can even do it in a microwave oven on defrost.

The beads stick to your skin causing burns as they don’t detach easily when hot.This is not mentioned in the safety instructions which state ‘No specific safety instructions’They do work well for keeping filament dry.

I use those silica gel on my 3d print spools of PLA, works really well and for a long time, since i live in a place with lots of moisture i thought i would have to change every week lol.but with Trustleaf 2kg Orange Self Indicating Silica Gel i can be more than 3 months without changing.My only point is the reuse part can be really trick if you dont use the right setting to dry the gel, because if you go to high you burn than and stop working completely. took me a few tries to understand my oven temperature to dry properly.Will buy again when my runs out.

Love these, used in conjunction with humidity sensor, totally reusable after drying out in the microwave

Works as intended and once the silica balls have changed colour from orange to green I placed a layer on a suitable microwaveable dish/plate or silicon tray and placed in 900w microwave setting on defrost for 5mins at a time Stirling occasionally until they turned back to orange. Don't use full power as this may burn them,

This is a must have to keep your filament dry when storing it.Easily added to containers and put between spools in storage to maintain dryness.Reusable as you can dry it in the oven, microwave (defrost only) or filament dryer.

Works a treat for helping keep 3d print filament dry.
