DE 19900597 A UPAB: 20000801 NOVELTY - Three-dimensional (3D) coordinates produced from a tool model, determines contour coordinates of individual layers making up the model. Each layer is constructed of paper and/or plastic films bonded on top of each other and cut to a profile or formed by laser sintering of plastic powder layers in a chamber, the cutting tool or sintering laser being controlled by the calculated contour coordinates. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is made for a sheet forming tool whose upper and/or lower tool is made from either laminated paper layers, laminated plastic films or laser-sintered powder containing polyamide. USE - For manufacturing tools for forming thin metal sheet. ADVANTAGE - Tool production uses fewer process stages to give a faster less expensive tool, even with complex shapes and permits rapid design changes to be made when required. Lower numbers of products can be made more economically and larger tools can be made in one piece
