Abstract
Recently the development of the prototyping technology using 3D printers is remarkable. However, it is impossible to make a prototype using same resin for the mass production, so that in this case it is necessary to make a mold. It was problem that these methods need high cost and long delivery time. We developed mold core and cavity by using FDM-3D printer (AM) for prototype manufacturing system made of specific-grade of resin, and evaluated as intensity target which produce 10 pcs of prototype less than 8 hours from receiving 3D data by web. To begin with 3D-data was received by web on the assumption, subsequently commenced designing mold core and cavity by using 3D-CAD, manufactured the core and cavity by FDM-3D printer, and mounted them on mold base, and produced prototypes by the mold injection process. Two types of 3D-data as product were provided for this study, which the box shape of 35mm×20mm×10mm (t=2mm) and the wheel shape as a little complex shape(925), and evaluated prototypes of each product about measurements and appearance characteristics.
