Abstract

A mask manufacturing method includes: preparing a base body of a toy figure based on base body data; and scanning the base body with a 3D scanner for acquiring scan data of the base body. The mask manufacturing method further includes: preparing mask mold data based on the scan data, the mask mold data including cover part data indicating a cover part for covering the base body therewith and exposing part data indicating an exposing part for exposing the base body therefrom; and shaping a mask mold with a 3D printer based on the mask mold data.

Claims (32)

1 . A mask manufacturing method comprising:

preparing a base body of a toy figure based on base body data;

scanning the base body with a 3D scanner for acquiring scan data of the base body;

preparing mask mold data based on the scan data, the mask mold data including cover part data indicating a cover part for covering the base body therewith and exposing part data indicating an exposing part for exposing the base body therefrom; and

shaping a mask mold with a 3D printer based on the mask mold data,

wherein the base body has an opening part on a lower surface thereof and between a front side and a rear side of the base body,

wherein the mask mold has an opening part on a lower surface thereof and between a front side and a rear side of the mask mold,

wherein the opening part of the mask mold corresponding to the opening part of the base body, and

wherein a mask jig is inserted into the opening part of the base body through the opening part of the mask mold.

2 . The mask manufacturing method according to claim 1 ,

wherein in the preparing the mask mold data, the mask mold data is prepared such that an internal shape of the mask mold represented by the mask mold data is larger than an external shape of the base body represented by the scan data by a flocking thickness for flocking on the base body.

3 . The mask manufacturing method according to claim 1 ,

wherein the base body data is also used as mass production data for the toy figure.

4 . The mask manufacturing method according to claim 1 ,

wherein the mask mold data includes split mask mold data indicating a plurality of split mask molds attachable to the base body from a plurality of directions,

wherein the mask mold includes the plurality of split mask molds that are shaped based on the split mask mold data, and

wherein the mask manufacturing method further comprises preparing the mask jig in which the split mask molds are attached to a support member.

5 . The mask manufacturing method according to claim 1 ,

wherein the mask mold data further includes an opening part data indicating an opening part of the mask mold corresponding to the opening part of the base body.

6 . A toy figure manufacturing method comprising:

preparing a base body based on base body data;

scanning the base body with a 3D scanner for acquiring scan data of the prepared base body;

preparing mask mold data based on the scan data, the mask mold data including cover part data indicating a cover part for covering the base body therewith and exposing part data indicating an exposing part for exposing the base body therefrom;

shaping a mask mold with a 3D printer based on the mask mold data; and

painting the base body, or another base body which has been formed based on the base body data, to which the mask mold is attached,

wherein the base body has an opening part on a lower surface thereof and between a front side and a rear side of the base body,

wherein the mask mold has an opening part on a lower surface thereof and between a front side and a rear side of the mask mold,

wherein the opening part of the mask mold corresponding to the opening part of the base body, and

wherein a mask jig is inserted into the opening part of the base body through the opening part of the mask mold.

7 . The toy figure manufacturing method according to claim 6 , further comprising, after the painting the base body:

flocking the base body to prepare a flocked base body; and

painting the flocked base body to which the mask mold is attached.
