Abstract

The present invention is intended to provide a cleaning apparatus for a 3-dimensional (3D) printing structure and a cleaning method for a 3D printing structure. To this end, the present invention provides a cleaning apparatus for a 3D printing structure, the cleaning apparatus including a hygroscopic paper supply part supplying a hygroscopic paper while the wound film-type hygroscopic paper is unwound, a hygroscopic paper collecting part winding and collecting the film-type hygroscopic paper, a film-type hygroscopic paper moving in a direction from the supply part to the collecting part between the supply part and the collecting part according to a mutual operation of the supply part and the collecting part, and a support part disposed on an opposite surface of a hygroscopic paper surface, on which the 3D printing structure is disposed, with respect to the film-type hygroscopic paper, and a cleaning method for a 3D printing structure, and a cleaning method for a 3D printing structure. According to the present invention, the 3D printing apparatus may be cleaned by using a minimum amount of solvent, and the mixture between materials may be prevented to remarkably improve the quality and integrity of the 3D printing structure.

First claim

1 . A cleaning apparatus for a 3-dimensional (3D) printing structure, comprising:
a hygroscopic paper supply part configured to supply a hygroscopic paper while the wound film-type hygroscopic paper is unwound; a hygroscopic paper collecting part configured to wind and collect the film-type hygroscopic paper; a film-type hygroscopic paper configured to move in a direction from the supply part to the collecting part between the supply part and the collecting part according to a mutual operation of the supply part and the collecting part; and a support part disposed on an opposite surface of a hygroscopic paper surface, on which the 3D printing structure is disposed, with respect to the film-type hygroscopic paper.

2 . The cleaning apparatus of claim 1 , further comprising a solvent supply part disposed between the supply part and the support part to supply a solvent to the hygroscopic paper supplied from the hygroscopic paper supply part.

3 . The cleaning apparatus of claim 1 , wherein the support part has an area equal to or greater than that of the 3D printing structure that contacts the support part with the hygroscopic paper therebetween.

4 . The cleaning apparatus of claim 1 , wherein the hygroscopic paper removes a material of an uncured portion of the 3D printing structure.

5 . The cleaning apparatus of claim 1 , wherein the cleaning apparatus for the 3D printing structure is disposed between different material supply parts in a 3D printing apparatus.

6 . A cleaning method for a 3D printing structure, comprising:
supplying a hygroscopic paper; disposing the supplied hygroscopic paper on a support part; allowing the 3D printing structure to mutually contact the hygroscopic paper disposed on the support part; separating the 3D printing structure from the hygroscopic paper; and collecting the hygroscopic paper.

7 . The cleaning method of claim 6 , wherein processes from the supplying of the hygroscopic paper to the collecting of the hygroscopic paper are repeatedly performed.

8 . The cleaning method of claim 6 , further comprising applying a solvent to the supplied hygroscopic paper at least one time.

9 . The cleaning method of claim 6 , wherein a material of an uncured portion of the 3D printing structure is removed through the allowing the 3D printing structure to mutually contact the hygroscopic paper.

10 . The cleaning method of claim 8 , wherein the processes from the supplying of the hygroscopic paper to the collecting of the hygroscopic paper are repeated at least five times.
