Title:
3D PRINTING METHOD FOR FORMING STACKED STRUCTURE OF DIFFERENT MATERIALS
Document Type and Number:
WIPO Patent Application WO/2022/097771
Kind Code:
A1
Abstract:
The present invention relates to a 3D printing method for forming a stacked structure of different materials, comprising: a first stacking step of providing a first slurry on a stage; a first curing step of emitting light at the first slurry to form one cross-section of a first target object and one cross-section of a first peripheral object spaced a predetermined distance from the first target; a step of repeatedly performing the first stacking step and the first curing step until the first target object is formed; a second stacking step of providing a second slurry so that the first target object is covered; a second curing step of emitting light at the second slurry to form one cross-section of a second target object and one cross-section of a second peripheral object spaced a predetermined distance from the first target object; and a step of repeatedly performing the second stacking step and the second curing step until the second target object is formed.
