The present invention provides a resin composition having high heat-resisting properties, with which a shaping can be performed in accordance with designed sizes using a fused deposition modeling method-3D printer, and from which a shaped object having a small warpage and small changes in sizes due to water can be obtained. The present invention relates to a resin composition for a shaping material of a fused deposition modeling method-3D printer, comprising cellulose fibers in a polyamide.

Resin composition for shaping material of fused deposition modeling method-3D printer and filamentary molded body thereof

Provided is a polyamide resin composition including 0.01 to 50 parts by mass of cellulose fiber in relation to 100 parts by mass of a polyamide resin, having a relative viscosity of 2.3 or more, and having an L-value, an a-value and a b-value in an Lab color space of 20 or more, 10 or less and 20 or less, respectively. The aforementioned polyamide resin composition is obtained by subjecting a polyamide resin composition having a relative viscosity of 2.2 or less to a solid phase polymerization.
