ABSTRACT:
A process for producing a three-dimensional model is provided. The process includes a step (layer formation step) of forming a layer of a powder material, the layer having a predetermined thickness, a step (cross-sectional shape formation step) of imagewise bonding the powder material layer by a binder according to sliced cross-sectional data of a modeled object so as to give a cross-sectional shape, and sequentially repeating the above steps. The surface gloss of the three-dimensional model obtained when measured at 20° is 20% or more. Furthermore, production equipment used in the above process is provided. Moreover, a three-dimensional model is provided that contains a powder material and a binder and is formed by imagewise curing the binder, the three-dimensional model having a surface gloss when measured at 20° of 20% or more.
