1. obtain particular individual face contour data: by the process to particular individual face one or more photo, particular individual face three-dimensional feature is obtained to the facial 3-D scanning of individuality, shooting or other approach;

2. extract the closed surface of three-dimensional mask: according to the facial three-dimensional feature of above-mentioned acquisition, by 3 d modeling software, set up particular individual face three-dimensional digital model; According to the closed surface of face contour feature extraction three-dimensional mask (namely prolong the bridge of the nose, closed surface that the wing of nose, cheek, lower jaw are formed to lip bottom) on facial mathematical model.Closed surface and face contour feature match, adapt, fit;

3. set up three-dimensional mask closely sealed frame 1 mathematical model:

Closely sealed frame 1 is laid component 3 be connected with filter body: based on closed surface mathematical model, is designed closely sealed frame 1 and filter body 2 or closely sealed frame by 3 d modeling software and is filtered body and lay component 3 and to be connected part 4.This coupling part 4 is designed buckle, screw thread, stickup, is squeezed the connected modes such as conjunction, hot rolling and filter body 2 or lay component 3 fit with filter body, echo mutually, reaches and makes closely knit, the gastight effect of mask main body;

4. the mathematical model of closely sealed frame 1 is printed by 3D printer and produce.

Fixture 5 described in this patent refers to: carrying mask main body, by mask main body with card, be etc. that mode is fixed on facial constructional device.

This three-dimensional mask is directed to specific individual face, adopts state-of-the-art 3D printing technique, is printed produce by 3D printer.The closely sealed frame material of above-described mouth mask is all material that can be suitable for 3D printing.Can be, but not limited to: metal, plastics, mineral, fiber, resin, plastic cement, silica gel, rubber, cloth, papery, wood materials and other.The width that the closely sealed frame 1 of mouth mask matches with face, fit, size, shape are not limit.

The mask material that 3D printing technique is produced is single, expensive, and in order to address this problem, the part of mouth mask of the present invention except closely sealed frame 1 uses conventional art to produce.In order in conjunction with 3D printing technique and traditional production technique, the technical scheme that we adopt is:

(1) closely sealed frame 1 and filter body lay component 3 by closely sealed connections of mode such as buckle, screw thread, stickups; The basic configuration of closely sealed frame 1 is designed to the circulus around mouth and nose; Filter body lays that the coupling part 4 of component 3 and closely sealed frame 1 is corresponding, fit, match, and reaches close-connected effect.Filter body is laid component 3 and is passed through industrial mass manufacture.Filter body is laid component 3 material and can be adopted but be not limited to silica gel, plastics, resin, rubber etc.Filter body lays component 3 with filter body 2 by hot rolling, and paste, the modes such as crowded conjunction combine;

(2) body 2 directly compact siro spinning technology filtered by closely sealed frame 1 and mouth mask.Mouth mask filter body 2 closely can be connected with closely sealed frame 1 by pasting, squeezing the modes such as conjunction or hot rolling.Filter body 2 to better make mouth mask to be connected with closely sealed frame 1, mouth mask filter body 2 can also be fixed-type by modes such as punching presses, namely mouth mask filter body 2 can be produced into given shape and have the linkage function such as buckle, screw thread match with closely sealed frame coupling part 4, adapt, mutually closely sealed.
