SUNLU E2 DESICCANT DRYING ECO SYSTEM

This is the system I use to dry my desiccant in Filament drying box Sunlu e2.

• Fine mesh inlay for anealing tray
• 4x clips to hold the mesh down and prevent warping of the mesh
• funnel to collect dryed desiccant

Technicals:

• USE HIGH TEMP MATERIAL THAT WILL BE ABLE TO WITHSTAND THE TEMPS THAT YOU WILL DRY YOUR DESICCANT AT.
• In my case desiccant tray and clips are made of carbon reinforced nylon (Fibertron PA612 CF-fast to print with minimal warping and will withstand the maximum drying temp of the SUNLU E2(110 degrees celsius)
• Anealing tray with mesh and clamps can hold roughly 700gr of desicannt (I recomend putting no more then 500g per drying since it will be more efective and easier to collect after drying)
• NOTE: If you're planning to dry at 110 degrees (I do) I recomend increasing the temp gradually since fast heating of the filament drier can couse small explosions of saturated with humidity desiccant balls and then they turn into a fine dust that is hard to clean from the dryer (ask me how I know)
• If you print the mesh from high temp material you don't need to remov it for anealing so you don't need clamps, you can just glue the mesh directly to the tray with hight temp glue.

FAQ:

1. Capacity? - Roughtly 700g of silica gel. Recomended amount - 500g (more efficient and easier to funnel into containers after drying)
2. PLA/PETG - for a funnel - Yes. For mesh and clamps absolutly not. You need a material that can withstand atleast 70 degrees celsius without softening for effective drying
3. Anealing the mesh and clamps before first use? - Anealing the mesh will most likely make it wrap (depending on the material) but I strongly recoment anealing the clamps before first use.

The story behind this project:

I've seen a lot of trays made for this dyer but I wanted to use annealing tray that is already inside, that's why I've developed this fine mesh that won't let the desiccint drop and help with funneling it after drying.

Since the mesh is very thin it could wrap during drying process so I also made those clips that hold the mesh in place and can be removed in need. Of cource you actually don't need to remove the mesh so  by your choice you can print only mesh and simply glue it with some high temp glue.
