Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing, and in particular to a method for color display of a photo after 3D printing and a pendant using the method. Background Art

[0002] 3D printed photos produce a three-dimensional relief effect. Compared with traditional flat photos, they are more vivid and novel. When made into souvenirs or gifts, they can embody a unique artistic beauty.

[0003] 3D printed photos display a three-dimensional relief effect through the light source on the back and the different light transmittances of the 3D printed layers of varying thicknesses. What you see is usually black and white, and not directly a color effect.

[0004] During the development process, we also used a transparent plastic sheet with color printed on it behind the 3D printing plate, so that the 3D printed pattern can be presented in color. However, the disadvantage is that this will form an extra layer of objects, and the positioning must be accurate to avoid misalignment of the color layer and the loss of beauty of the image. Summary of the invention

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a method for color display of a photo or picture after 3D printing and a pendant using the method. The method flips the color photo or picture horizontally (mirror image), prints the color on a self-adhesive transparent printing sticker, and then aligns and sticks the sticker on the flat back side of the 3D printing plate, so that the 3D printed photo or picture can display a colorful three-dimensional effect when facing the back light source.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions: The present invention provides a method for color display of a photo image after 3D printing, characterized in that it comprises the following steps: Step 1: Use image editing software to flip the color photo or picture horizontally, and then print it on a self-adhesive transparent printing sticker with a color printer; Step 2: Then align the sticker and stick it on the flat back of the original 3D printing plate. This way, when there is a uniform light source coming through from the back, the 3D printed photo or image will show a colorful effect.

[0007] The present invention also relates to a pendant for luminously displaying 3D printed photos and pictures, characterized in that it comprises an upper cover and a lower seat connected together by snaps, a cavity is formed between the upper cover and the lower seat, a transparent thin plate for dust prevention is installed in the groove inside the upper cover; 3D printing paper for printing a three-dimensional relief photo / picture is installed in the cavity between the upper cover and the lower seat, and a self-adhesive transparent printing paper is adhered to the back of the 3D printing plate; an LED light-emitting plate is arranged on the rear side of the 3D printing plate; A charging module, a step-down module and a rechargeable battery are also installed in the lower seat, and a toggle switch is installed on the side of the lower seat. The rechargeable battery is connected to the input end of the charging module, and the positive and negative output terminals of the charging module are respectively connected to the step-down module and the corresponding positive and negative terminals of the toggle switch. At the same time, the step-down module is connected to the toggle switch; the output terminal of the step-down module is connected to the LED light-emitting board.

[0008] The beneficial effects of the present invention are: 1. The display of 3D printed photos bids farewell to black and white, and the color display is more vivid.

[0009] 2. The 3D printed photo plate is integrated and does not need to form multiple layers of materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0015] A method for color display of a photo image after 3D printing, comprising the following steps: Step 1: Use image editing software to flip the color photo or picture horizontally, and then print it on a self-adhesive transparent printing sticker with a color printer; Step 2: Then align the sticker and stick it on the flat back of the original 3D printing plate. This way, when there is a uniform light source coming through from the back, the 3D printed photo or image will show a colorful effect.

[0016] like Figure 1-Figure 2 As shown, the method for color display of a photo image after 3D printing and the pendant using the method described in the above embodiment 1 are applied to the pendant, the pendant comprises an upper cover 1 and a lower seat 10 connected together by a snap, a cavity is formed between the upper cover 1 and the lower seat 10, a transparent thin plate 2 for dust prevention is installed in the inner groove of the upper cover 1; a 3D printing paper for printing a three-dimensional relief photo / image is installed in the cavity between the upper cover 1 and the lower seat 10, a self-adhesive transparent printing paper 4 is adhered to the back of the 3D printing plate 3; an LED light-emitting board 5 is arranged on the rear side of the 3D printing plate 3; A charging module 9, a step-down module 8 and a rechargeable battery 6 are also installed in the lower seat 10. A toggle switch 7 is installed on the side of the lower seat 10. The rechargeable battery 6 is connected to the input end of the charging module 9. The positive and negative output electrodes of the charging module 9 are respectively connected to the step-down module 8 and the corresponding positive and negative electrodes of the toggle switch 7. At the same time, the step-down module 8 is connected to the toggle switch 7; the output end of the step-down module 8 is connected to the LED light-emitting panel 5.

[0017] Working principle: This pendant connects the rechargeable battery 6 to the input of the USB charging module 9. Then the positive and negative outputs of the USB charging module 9 are respectively connected to the corresponding positive and negative outputs of the step-down module 8 and the toggle switch 7, and the step-down module 8 and the toggle switch 7 are connected together, so that the toggle switch 7 can be used to control whether the current flows to the step-down module 8. The output of the step-down module 8 is connected to the LED light-emitting board 5 to provide a light source. The above components, together with the 3D printing board 3 and the dustproof transparent thin plate 2, are placed in the lower seat 10, and then the upper cover 1 and the lower seat 10 are buckled together to form an integral assembly.

[0018] The pendant uses a voltage reduction module 8 to reduce the 5V voltage of the rechargeable battery 6 and the USB external power supply through the USB charging module 9 to the 3V power required by the LED light-emitting board 5, thereby generating a light source for displaying 3D printed photos. Then, the light source and the 3D printing board 3 are placed in the pendant-shaped component to form a rechargeable 3D printed photo light-emitting pendant.

[0019] Use image editing software to flip the color photo or picture horizontally (mirror), then print it on a self-adhesive transparent printing sticker with a color printer, and then align the sticker and stick it on the flat back of the original 3D printing plate 3. In this way, when there is a uniform light source passing through from the back, the 3D printed photo or picture can show a color effect.

[0020] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
