Abstract
A non-contact support structure supports a metal additive manufactured product that includes a first shape structure having an overhang structure. The non-contact support includes: an opposite surface configured to face a surface of the first shape structure; a bottom surface configured to contact a base on which the metal additive manufactured product is provided; and an intermediate surface perpendicular to both the opposite surface and the bottom surface and including at least one opening.

A non-contact support structure for supporting a metal additive manufactured product comprising a first shape structure that has an overhang structure,
- the non-contact support structure comprising:
- an opposite surface configured to face a surface of the first shape structure;
- a bottom surface configured to contact a base on which the metal additive manufactured product is provided;
- and
- an intermediate surface perpendicular to both the opposite surface and the bottom surface and comprising at least one opening.
A method of manufacturing a metal additive manufactured product, the method comprising:
- performing metal three-dimensional (3D) printing on a base, based on design data to obtain a metal additive manufactured product comprising a first shape structure that has an overhang structure, and a support structure that supports the first shape structure;
- separating the printed metal additive manufactured product from the support structure;
- and
- processing a surface of the metal additive manufactured product based on a contact with the support structure,
- wherein the support structure comprises:
- a non-contact support structure which, based on the performing the metal 3D printing, is spaced apart from the metal additive manufactured product, and
- a contact support structure which, based on the performing the metal 3D printing, is in contact with the metal additive manufactured product to support the metal additive manufactured product.
