DUAL CURABLE CERAMIC SLURRY COMPOSITION FOR 3D PRINTING AND METHOD FOR MANUFACTURING DUAL CURABLE CERAMIC STRUCTURE USING SAME
The present invention relates to a dual curable ceramic slurry composition for 3D printing and a method for manufacturing a dual curable ceramic structure using same. More specifically, the present invention provides a dual curable ceramic slurry composition for 3D printing, and a method for manufacturing a dual curable ceramic structure using same, wherein the dual curable ceramic slurry composition for 3D printing comprises: a ceramic slurry composition containing inorganic particles and a photopolymerizable monomer, wherein the photopolymerizable monomer is an acrylate monomer having two or more functional groups; and a monomer having both an alicyclic epoxy group and an acrylate group. According to the present invention, a ceramic structure having a complex shape without interlayer delamination and distortion can be manufactured through 3D printing by doubly curing a dual curable ceramic slurry composition by using an acrylate with rapid photopolymerization characteristics and an epoxide-based photosensitive resin with excellent mechanical properties.
