Abstract

A polylactic acid resin composition, which comprises: a hard segment containing a polylactic acid repeat unit; and a soft segment containing a polyurethane polyol repeat unit in which polyether-based polyol repeat units are linearly connected to each other via a urethane linkage, can be processed at low temperatures and at high rates, has a high solidification rate, and is eco-friendly, due to a low melting point thereof, and thus is useful for 3D printing.
