3d modeling powder material and 3d modeling set, and 3d modeled object producing method and producing apparatus

PROBLEM TO BE SOLVED: To provide a 3D modeling powder material capable of forming a 3D modeled object strong enough to maintain complex stereoscopic (three-dimensional (3D)) shape.SOLUTION: A 3D modeling powder material is by coating a base material particulate with a resin. The resin includes a resin having a functional group represented by the general formula 1 in the figure, where Arepresents O or NH; and R, Rand Reach represent CH, CH, CHor CH.SELECTED DRAWING: Figure 1
