CA
In order to automatically perform lamination according to the shape of the electric discharge machining electrode model 1 designed by D (Computer Aided Design), first, the numerical model defined on the computer is cut in horizontal planes at equal intervals and sliced. Create a group of graphic data. Next, they are taken out from the lower end, and the light beam 4 is scanned based on the shape to solidify the solidified layer 5
To form. After the solidified layer 5 is formed, the base plate 2 is lowered by a predetermined dimension to lay an uncured resin layer 3 having a predetermined thickness thereon, and the next slice pattern is exposed and solidified. This is repeated until reaching the upper layers of the model. During the curing reaction, the upper and lower layers are firmly bonded to each other, and the whole becomes a solid three-dimensional model of plastic. This three-dimensional model can be made to have conductivity that can be used as an electric discharge machining electrode by attaching a metal film by a plating or coating method.
