摘要： Provided is a three-dimensional shaped article with relatively high strength and relatively high accuracy. A sintering and shaping method includes: a shaping layer forming process of forming a shaping layer by using a sintering and shaping material in which inorganic particles are included; a process of applying a liquid binding agent, in which a thermoplastic resin and inorganic particles are included, to a desired region of the shaping layer; a process of curing the liquid binding agent, which is applied, to form a shaping cross-sectional layer (shaping portion); a process of removing a region (non-shaping portion) of the shaping layer to which the liquid binding agent is not applied; and a process of heating the shaping cross-sectional layer that is laminated for a sintering treatment.

摘要： A method for producing a three-dimensionally shaped object by stacking layers includes forming each layer using a three-dimensional shape composition containing particles, measuring the thickness of the layer, and ejecting onto the layer a liquid binder containing a binding agent capable of binding the particles. For the ejecting, the amount of the liquid binder to be ejected per unit area of the layer when viewed from above is adjusted according to the result of the measuring.
