Abstract: A mold for resin injection molding 1 having a shaping region formed by a low-density shaped portion 22 and a high-density shaped portion 21 in which each ventilation channel 32 for gas existing between an external region and a molding portion region forms a hollow state surrounded by a peripheral wall having any one or both of the high-density shaped portion 21 and the low-density shaped portion 22, and the secondary vent 33 connecting communicatively with a region molding portion is formed only by a low-density shaped portion 22 with thickness thinner than that of the shaping region.

Abstract: An apparatus for producing a three-dimensional shaped product in which a powder and a shaped article are loaded on a base plate, a frame body is installed upright on a table, a support projecting from the frame body and/or a restraining support provided at the top of the frame body are used to support the base plate, the base plate is supported by arranging the center of gravity of the base plate so as to be present, two or more recesses provided at the back of the base plate are fitted into two or more extension supports which cross each other and/or restraining supports, and projected parts provided on supports and/or wall parts of the frame body are contacted with horizontally surrounding parts of the base plate on both sides in the longitudinal direction of at least one recess among the recesses, thereby attaining the above object.

Abstract: An apparatus for producing a three-dimensional shaped product capable of decreasing thermal dissipation due to thermal conduction of a heating device or a cooling device loading a base plate, in which powder is sequentially sintered on a table and a base plate inside a shaping tank, wherein a space of vertical direction is formed on the table or the space is formed and a heat insulating material is filled into the thus formed region, a heating device or a cooling device which loads the base plate supporting the sintered layer is firmly fixed.

Abstract: An apparatus for producing a three-dimensional shaped product installs on a surface of a table a base plate which loads powder and a shaped article, with a vertical space being formed. A frame body is installed upright on the table. The base plate is placed on a support horizontally projecting from the frame body and/or a step portion which provides an inner direction part of the table of the frame body. The base plate is supported so the center of gravity of the base plate is inside a triangle formed by three locations or a quadruple formed by four locations inside a region of the support or the step portion on which the base plate is placed, and the part projecting above the support and/or an inner wall of the frame body are contacted with a horizontally surrounding part of the base plate at three or more locations.

Abstract: A method for producing an artificial bone capable of accurate molding at a joined part with appropriate strength, in which electromagnetic waves or electron beams are irradiated to a layer of at least type of powder selected from metal biomaterials, ceramics for the artificial bone and plastic resins for the artificial bone based on image data corresponding to a shape of the artificial bone, thereby effecting sintering or melting, and the thus sintered layer or melted and solidified layer is laminated, such that a surface finish step is adopted that inner faces and/or outer faces of both ends and their vicinities configuring the joined part to a human bone part are polished by a rotating tool based on the image data and also irradiation of electromagnetic waves or electron beams at both ends and their vicinities constituting the joined part is set greater than that at other regions.
