- 3D 3 LIGHT-WEIGHT 3D PATTERN STRUCTURE FOR BIDNER-JET 3D PRINTING THE 3D PATTERNED MOLDS FOR CASTING PROCESS AND THE CASTING PROCESS USING THEM
The present invention relates to a three-dimensional lightweight pattern structure for binder-jet 3D printing, a mold for casting process using the same, and a casting process method. More specifically, in the 3D pattern structure for 3D printing, it is composed of a first stacked surface and a second stacked surface formed to include a plurality of empty spaces, and the second stacked surface is a lower portion of the first stacked surface. The three-dimensional lightweight pattern structure for 3D printing, and a casting and casting process method using the binder-jet method 3D printing, characterized in that the plurality of empty spaces are respectively formed in a spherical shape and arranged to form a dense structure between each other. It is about.
