Abstract

Provided is a fast-eluting three-dimensionally molded object, which is formed by fused deposition modeling type three-dimensional molding and quickly elutes an active component. The fast-eluting three-dimensionally molded object is formed by the fused deposition modeling type three-dimensional molding and includes an active component, a water-soluble thermoplastic polymer, a water-soluble sugar and/or a water-soluble sugar alcohol, and a plasticizer component. The fast-eluting three-dimensionally molded object has an elution rate of the active component of 80% or higher within 85 minutes by a dissolution test method in the Japanese Pharmacopoeia, Sixteenth Edition.
