Recharge your silica beads on your printers hot bed.

Simply pour the beads into the tray and turn the bed on.

About 90 C  / 194 F will be fine. You can gently stir it from time to time if you like.

You can use it with or without the lid, I mainly put a lid on it for the part when I pour it back into my storage container.

Once the beads has returned to it's original color just turn the bed off and wait for it to drop somewhere between 40 C / 104 F and 50 C / 122 F (I haven't tried to take it off the bed before that temperature so I don't know if that would mess upp the tray). Put the lid on and hold it gently together while you pour the beads out.

The fewer the beads the faster it finishes.

I printed it with PETG for it to handle the heat better.
