1. A production method for a three-dimensionally shaped object, the method comprising:
forming a thin layer from a powder material comprising a particulate resin composition, and
selectively irradiating the thin layer with laser light, thereby forming a shaped object layer comprising a plurality of the resin compositions melt-bonded to one another, wherein
the forming of the thin layer and the irradiating with the laser light are repeated a plurality of times to stack the shaped object layers, thereby shaping a three-dimensionally shaped object,
the particulate resin composition comprises resin particles containing a polysaccharide nanofiber and a thermoplastic resin,
the particulate resin composition has a content of the polysaccharide nanofiber of 1 to 70 mass %, and
the composition has a melting temperature Tm, a viscosity of the composition changes within a range of Tm −20° C. to Tm +20° C, and a maximum value of loss modulus in the range is 10 to 1,000 times a minimum value of the loss modulus in the range.
