The idea is to cut your model into slices and cut cardboard with the shape of your model slices. When staking the slices in the correct order you get your model in rough finish to start sanding.
The final model will have really good weight and resistance. A great advantage of this method it's its precision since the model comes out almost exact as the 3d computer model. A disadvantage is the amount of time you may spend cutting and sanding.
This is kind of a replacement for a laser cutter and MDF plaques. For me it was faster and more controlable than laser cutting MDF. Hope it helps!
