The present invention addresses the problem of providing: a resin composition and a filamentous material for forming a three-dimensional additively manufactured object having excellent durability (strength) in external bending stress; a three-dimensional additively manufactured object produced using the filamentous material; and a method for producing the three-dimensional additively manufactured object. This resin composition is for use in forming shaped objects by a thermal fusion/extrusion method, and is characterized by comprising a resin including a polymer having a partial structure represented by general formula (1). General formula (1): -(X)n-J-A (In the general formula, X represents -C(=O)-, -C(=O)NH-, -SiR1R2-, or -S-, where R1 and R2 each represent a substituent, J represents a linking group, A represents a functional group, and n indicates 1 or 0.)
本发明所要解决的问题是:提供一种树脂组合物和丝状材料,用于形成在外部弯曲应力下具有优异耐久性(强度)的三维快速成型物体;提供一种使用该丝状材料生产的三维快速成型物体;以及提供一种生产该三维快速成型物体的方法。该树脂组合物用于通过热熔/挤压方法形成异形物体,其特征在于包含一种树脂,该树脂包括具有通式(1)所代表的部分结构的聚合物。通式(1)-(X)n-J-A(通式中,X 代表-C(=O)-、-C(=O)NH-、-SiR1R2-或-S-,其中 R1 和 R2 各自代表取代基,J 代表连接基,A 代表官能团,n 表示 1 或 0)。
