Title:
RADIATION CURABLE COMPOSITION FOR 3D PRINTING
Document Type and Number:
WIPO Patent Application WO/2021/215647
Kind Code:
A1
Abstract:
The present invention provides a radiation curable composition for 3D printing, comprising: an epoxylated vegetable oil oligomer into which a (meth)acrylate group is introduced; a urethane (meth)acrylate oligomer; a (meth)acrylate monomer; and a photopolymerization initiator. The radiation curable composition for 3D printing, according to the present invention, comprises, as a main component, an epoxylated vegetable oil oligomer into which a (meth)acrylate group is introduced as an eco-friendly material, and thus causes no unpleasant odor, and suitably mixes the vegetable oil oligomer with another reactive oligomer, particularly, a urethane (meth)acrylate oligomer, and a monomer, thereby enabling the implementation of physical properties such as hardness, elongation and strength, which are appropriate in the formation of a three-dimensional product by means of 3D printing.
