In paper layer technology, the product is built up from layers of thin paper. The computer "cuts up" the 3D CAD representation of the product into separate layers. Each is plotted on the paper with a special toner. The toner forms a cross section at the level of the present layer. Each successive layer is placed on top of the previous one and lightly heated and pressed on. Through this, the toner bonds with the previous layer, after which a plotter knife is used to cut the surplus paper away. As the paper surrounding the actual cross section is not bonded (no toner being present), the waste material can easily be removed.
The paper model offers fine detail, due to the small paper thickness used (0.08 mm). Its surface is treated with an epoxy resin to add strength, smoothness and colour to the model. A wide variety of finishes is within easy reach. In comparison with alternative rapid prototyping methods, paper layer technology is cheap.
Paper layer technology is very often used to produce "visuals" or "touchables" for marketing purposes. The models are however also suitable as sand casting patterns; as well as patterns for making silicone rubber moulds, to cast plastics or low melting point non-ferrous alloys in.
