Filament Storage Idea’s
If your looking to store your filament on a budget – kitty litter with silica is the best bet. It’s effective, cheap and easily attainable. A large bag will last you quite a while. You will want to poor enough kitty litter in to completely cover the bottom of your container.
Another affordable way to keep water out is to collect discussant and silica packets. These are those little white packets you often find in a new pair of shoes or other new items like pill containers. One or two of these wont do much but, I’ve found that if you ask people you know to keep their eyes out for them – you will find a ton in no time at all.
No matter which direction you go, you will want a good container. Rubbermaid seems to work the best and is readily available within the U.S. They also come in just about any size and shape you can imagine.
Another great container idea is a standard, round 5 – gallon bucket. These work particularly well for storing filament that is on spools.
There is more than just moisture to protect your filament from. Other sources that can harm your filament or hotend include: Sun (makes filament brittle after constant exposure) & Dust ( it accumulates on filament and then it’s pulled into the hotend. Overtime this can clog or damage your extruder.)
At RepRap Squad’s shop we use a combination of all of these ideas and techniques. That way we can keep the amount of storage space used low, while making sure our filament is always ready to be used.
