Autimatic system for layers' borders export in jpeg

The recently added tool for 3d printing is good but the next step is a tool that would allow users to choose the thickness of the horizontal layers in which to cut the 3D drown objects and then export each layer in a single jpeg image with just the borders in black and all the rest in white.. so that it can be used with laser cutters such as LaserPecker 4 to create 3D objects by sticking together layers of paper or wood or leather or other materials..
