What is claimed is:
1. A polylactic acid resin composition for three-dimensional (3D) printing, comprising:
(a) a hard segment comprising a polylactic acid repeat unit represented by Formula 1; and (b) a soft segment comprising a polyurethane polyol repeat unit in which polyether-based polyol repeat units represented by Formula 2 are linearly linked via urethane...
The present invention relates to a polylactic acid resin composition for three-dimensional (3D) printing, which has not only a lower melting temperature than those of conventional polylactic acid resin compositions, to thereby undergo low-temperature and high-speed processing, but also a high solidification rate and eco-friendly characteristics.
