Title:
3D PRINTING CERAMIC SLURRY COMPOSITION HAVING HIGH FLEXURAL STRENGTH
Document Type and Number:
WIPO Patent Application WO/2022/034978
Kind Code:
A1
Abstract:
The present invention pertains to a ceramic slurry composition that can increase ceramic filling density and minimize photocuring shrinkage to achieve excellent flexural strength, improved interlayer adhesion, and structural stability in 3D printing, especially 3D printing combining SLA and DLP. Specifically, in the ceramic slurry composition according to the present invention, a photocurable monomer or oligomer containing two or less functional groups is used as a photocurable binder by optimizing the composition and type of the photocurable monomer or oligomer, and thus it is easy to achieve proper flowability, high interlayer adhesion, a high flexural strength of at least 500 MPa, and excellent structural stability, especially in an article obtained by 3D printing combining SLA and DLP.
