Document Type and Number:
WIPO Patent Application WO/2021/066295
Kind Code:
A1
Abstract:
The present invention relates to a three-dimensional object using 3D printing and a manufacturing method therefor, wherein a desired pattern is produced in a flat shape by applying a 3D printing technology and then the desired pattern is easily formed into a desired three-dimensional shape by using a mold, and thus, a support is not required for producing a three-dimensional object and a three-dimensional object with various textile patterns can be simply and easily produced. The method for manufacturing a three-dimensional object using 3D printing according to the present invention may comprise the steps of: (S1) inputting pattern information of a pattern sheet to a 3D printer; (S2) mounting a base sheet on a working bed of the 3D printer; (S3) forming a pattern sheet in a flat shape having a predetermined pattern by outputting a thermoplastic resin filament onto the base sheet according to the pattern information input to the 3D printer; (S4) placing, on a mold having a three-dimensional shape, a composite of the pattern sheet output and bonded onto the base sheet and heating the composite to a predetermined temperature range to form the composite of the base sheet and the pattern sheet into a three-dimensional shape corresponding to the mold; and (S5) manufacturing the composite into a three-dimensional object having a final three-dimensional shape by finishing the border of the composite of the base sheet and the pattern sheet, the composite being formed into the shape corresponding to the three-dimensional shape of the mold.
