3 3D PRINTER FILAMENT USING BIODEGRADABLE RESIN COMPOSITION HAVING IMPROVED WHITENESS AND MECHANICAL PROPERTIES

摘要

In the case of a filament for a three-dimensional printer using a biodegradable resin such as polylactic acid, a biodegradable resin is used to solve the whiteness problem by omitting an additional white pigment or dye addition process for processing a white filament, Disclosed is a filament for a three-dimensional printer using a biodegradable resin capable of securing physical properties. The present invention relates to a three-dimensional printer filament produced by extruding and cooling a biodegradable resin composition, wherein the biodegradable resin composition comprises (A) 50 to 99.5% by weight of a biodegradable resin having crystals; And (B) 0.5 to 50% by weight of an amorphous resin.
