Description

Technical Field

[0001] The invention belongs to the field of art production, and in particular relates to a method for producing shadow puppets for teaching. Background Art

[0002] At present, there are common courses on making art products in the art teaching tasks of primary and secondary schools. However, there are few types of art products that can meet the requirements of this course, and they are usually in a fixed shape after being made, which makes users less interested. Movable shadow puppet artworks (such as classic characters or animal characters in the four great classics) can make up for this defect and promote the inheritance of traditional Chinese culture. However, the general shadow puppet production process at least includes the steps of selecting leather, making leather, drawing, cutting, engraving, hand-carving, coloring, splicing, etc., and the irregularity of the color and shape of the shadow puppet characters further makes the production of shadow puppet artworks relatively complicated.

[0003] CN109011659A discloses a method for making shadow puppets, which requires decomposing the designed shadow puppet pattern into several parts according to the limb joints before coloring, and drawing the parts separately on the surface of the substrate, and also requires using scissors, carving knives and other tools to cut and hollow out the parts and the hollow patterns drawn on the surface of the parts. This process is too lengthy for primary and secondary school users, and the knife tools used also have extremely high safety hazards.

[0004] CN102700207A discloses a method for making a new type of shadow puppet material. Although it no longer uses a knife, it is necessary to draw a pre-designed pattern on a base material and bake it. However, it is not suitable to use a baking device in general teaching scenarios, and the effect of pattern drawing varies from person to person, and the teaching task cannot be guaranteed. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a method for making shadow puppets for teaching, which aims to reduce the difficulty of traditional shadow puppet making with the help of modern technology, increase user interest and develop user aesthetics.

[0006] According to a first aspect of the present invention, the present invention first provides a method for making a shadow puppet for teaching, comprising:

[0007] S1: A user selects a target shadow puppet, where the target shadow puppet includes a first structure and a plurality of second structures located in different directions on a plane;

[0008] S2: Three-dimensional pattern design: input the first pattern corresponding to the first structure and the plurality of second patterns corresponding to the plurality of second structures into the computer respectively, design a plurality of first hinge holes for hinged connection with the plurality of second patterns in the first pattern, design a plurality of second hinge holes corresponding to the plurality of first hinge holes and a plurality of connection holes connected with the shadow puppet control lines in the plurality of second patterns, divide the first pattern into at least two sub-printing areas, and / or divide at least one second pattern into at least two sub-printing areas;

[0009] S3: 3D printing: adding the resin substrate into the 3D printer, setting the printing parameters, and printing the corresponding first structural member and the plurality of second structural members according to the first pattern and the second pattern designed in step S2, wherein at least two sub-printing areas in the first structural member and / or the plurality of second structural members are printed with resin substrates of different grayscales, and a plurality of coloring areas are formed;

[0010] S4: The user uniformly colors the multiple coloring areas with pigments of different colors, air-dries the pigments, and finally hinges the first structural member and the multiple second structural members.

[0011] According to an embodiment of the present invention, in step S1, the target shadow puppet is a person, plant, animal or object character recorded in a book, film or comic.

[0012] According to one embodiment of the present invention, the plane area of ​​the first structure is at least greater than the sum of the plane areas of two second structures, and the plurality of second structures are identical to or different from each other.

[0013] According to one embodiment of the present invention, the plurality of second structural members are made of resin substrates having the same or different grayscales.

[0014] According to one embodiment of the present invention, the 3D printer in step S3 is a SLS printer.

[0015] According to one embodiment of the present invention, in step S3, when printing to the plurality of hinge hole regions and the plurality of connection hole regions, the resin amount in the printing parameters is set to zero.

[0016] According to one embodiment of the present invention, the resin substrate is one of PVC, PP, and PE, and the resin substrate includes masterbatches of different grayscales.

[0018] According to one embodiment of the present invention, the colors of the plant pigment include at least six colors: red, yellow, blue, green, purple and gray.

[0019] In general, the above technical solution conceived by the present invention has the following technical advantages compared with the prior art:

[0020] 1. In the teaching shadow puppet making method of the present invention, users can freely choose the intended characters, and the traditional shadow puppet outline making method is replaced by additive making, so there is no need for corresponding subtractive tools, which greatly improves safety, avoids differences in labor, reduces production difficulty, and uses coloring as the most important teaching content, greatly improving the efficiency of art teaching.
