There is a new flexible and elastic filament from Kai Parthy, a scientist who also created Laywood and Moldlay.

I am considering Rubberlay as an alternative to Filaflex which doesn't print very easily on my machine.
Does anyone have any experience with this material? I would also like to know what type of material it is so I know what I can use it for.
