FORMATION OF THREE-DIMENSIONAL HARD BODY AND FORMING DEVICE THEREFOR

PURPOSE:To form the three-dimensional hard body which is highly accurate and hard by repeating a stage for pressing powder stuck with a condition ipartation curing type resin onto the surface of a base body and applying specified conditions to the resin to form a hard powder layer. CONSTITUTION:This forming device 11 has a static electricity generating surface (hereafter described as the powder holding surface) 13 capable of forming a part for generating static electricity (hereinafter described as the powder holding part) 12 of a prescribed shape on the rear surface and a shape operating means 15 of a control circuit 14 for operating the shape for generation of the static electricity formed by the powder holding surface 13. Further, the device has a powder applying means 16 for applying the powder consisting of a hard material to the powder holding part 12 and a resin applying means 17 for adhering the photosetting resin prior to curing to the powder. The device has a laminating means 19 for pressing the powder to the base body 18 or the cured powder layer L by driving at least either of the base body 18 which is a base to be formed with the three-dimensional hard body on the surface or the powder holding surface 13 and a resin curing means 20 for forming the cured powder layer L consisting of the photosetting resin and the powder by applying light to the photosetting resin.
