Title:
RESIN COMPOSITION AND METHOD FOR PRODUCING THREE-DIMENSIONALLY SHAPED OBJECT USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/131352
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a resin composition for forming three-dimensionally shaped objects having high dimensional accuracy.
In order to achieve the purpose, the resin composition is used in a three-dimensional shaping method wherein either forming a thin layer that comprises a particulate resin composition and selectively irradiating the thin layer with laser light are repeated or melt-extruding a resin composition into a filament shape and forming a layer of the filament-shaped extruded resin composition are repeated, thereby forming a three-dimensionally shaped object. The resin composition of the present invention has a particulate or filament shape, comprises polysaccharide nanofibers and a resin, and has a content of the polysaccharide nanofibers of 1-70 mass%. In the resin composition, the maximum value of loss modulus at temperatures in the range of (melting temperature)±20°C is 10-1,000 times the minimum value of loss modulus at temperatures in the range of (melting temperature)±20°C.
