Can anyone please explain to me exactly what "Stick Filament" is, and how you can use it in place of a roll of filament on an FFF printer? Here is a diagram I found that explains it.



I assume it is just sticks of filament. Can you feed these into your printer just like you would regular filament that comes on spools, or do you need a special device or printer in order for printing with this stuff?

Any help would be greatly appreciated.
