    摘要: Methods and apparatus are provided for rapidily prototyping a three-dimensional object from a plurality of sequential layers wherein each layer is cut after being fused with a preceding layer. A first sequential layer having a peripheral edge and an exposed face is cut from a first sheet of material using a machine tool path generated from a CAD model of the object. A solvent is then applied to a face of a second sheet of material. The second sheet of material is placed in contacting face-to-face relation with the first sequential layer such that the solvent fuses the face of the second sheet of material with the exposed face of the first sequential layer. A second sequential layer having a peripheral edge and an exposed face is cut from the second sheet of material along a respective machine tool path generated for the second sequential layer. The above procedure is repeated until all remaining layers of the prototype part are produced.

    摘要: A process for producing vinyl chloride resin products involving the step of adhering vinyl chloride resin members to each other, wherein said step comprises applying to a portion of at least one of said members a compound for vinyl chloride resin capable of dissolving said resin, and bringing the two members into close contact with each other. The use of a compound for vinyl chloride resin showing compatibility with said resin as an adhesive enables the production of safer vinyl chloride resin products than those produced using organic solvents.
