[0059] like Figure 1 As shown, a 3D printing method for crystal diamond is provided, and the 3D printing method comprises:

[0060] Step S110, obtaining a 3D stereoscopic image of the crystal diamond.

[0061] The 3D stereoscopic image of the crystal diamond is the target image to be printed. In the specific printing production process, the 3D stereoscopic image of the crystal diamond needs to be designed in combination with actual needs.

[0062] Step S120, obtaining corresponding 3D stereoscopic image parameter information according to the 3D stereoscopic image, wherein the 3D stereoscopic image parameter information includes the position, area, slope of each diamond facet, the connection angle between each diamond facet, and the volume information and height information of the 3D stereoscopic image.

[0063] The 3D stereoscopic image of the crystal diamond contains the corresponding 3D stereoscopic image parameter information. The 3D stereoscopic image contains each diamond facet. The position, area, slope, connection angle between each diamond facet, volume information and height information of the 3D stereoscopic image are all image parameter information that needs to be obtained.

[0064] Step S130 , establishing a printing data control model according to the 3D stereoscopic image parameter information and the set total spraying thickness information.

[0065] The total spraying thickness information is the overall thickness information corresponding to the 3D stereoscopic image of the crystal diamond.

[0066] Step S140, after the printing data control model is established, a substrate positioning instruction is generated.

[0067] In one embodiment, the printing material is paper, and the central controller generates a printing material positioning instruction after establishing a printing data control model.

[0068] Step S150, acquiring positioning data of the target substrate according to the substrate positioning instruction.

[0069] During the printing process, the target substrate needs to be kept in a suitable and correct position. The substrate positioning instruction includes the positioning data of the target substrate. Therefore, the positioning data of the target substrate can be obtained according to the substrate positioning instruction.

[0070] Step S160: determining whether the target printing object is located within a preset position range according to the positioning data.

[0071] Step S170, when it is determined that the target printing material is located within the preset position range, a printing instruction is generated according to the printing data control model.

[0072] The target printing material usually needs to be placed within a certain preset position range. After obtaining the positioning data, it can be further determined whether the target printing material is located within the preset position range.

[0073] Step S180, spraying a preset spraying material onto a target substrate according to the printing instruction to obtain a preliminary printed product including a spraying layer.

[0074] Step S190, performing preliminary pre-curing treatment on the sprayed layer to control the leveling property of the sprayed material, and obtaining a pre-cured printed product.

[0075] Step S200 , performing full curing treatment on the pre-cured printed product to obtain a printed product containing a 3D stereoscopic image of a crystal diamond.

[0076] In one embodiment, the preset spraying material is resin ink.

[0077] Among them, the initial pre-curing treatment usually uses LED ultraviolet lamps for irradiation to control the leveling of the spraying material to obtain a pre-cured printed product.

[0078] In this embodiment, the above-mentioned 3D printing method, compared with the traditional complex processes such as molds, molding, positioning, and die-cutting, can generate printing data program files and corresponding printing instructions by establishing a printing data control model, so that it can be directly printed on various special materials such as paper, film, and leather by printing, and can achieve one-time output of a single process. The process is simple, which can reduce the complexity of the process, realize batch 3D printing of crystal diamond effects, and reduce economic and labor costs; by establishing a printing data control model, the needs of different terminals can be met, and the diamond effects of different sizes and different cut surfaces can be output and sprayed at one time, so as to meet the needs of personalized customization, completely solve the limitation that traditional manual diamond pasting cannot be compatible at the same time, and realize high-efficiency printing while expanding the possibility of extension; in addition, the above-mentioned 3D printing method can also be compatible with many other digital processes. The above-mentioned 3D printing method has the advantages of digital management, no pollution, no molds, and reduced resource waste.

[0079] In one embodiment, the control accuracy of the leveling property is 427.5~472.5 DPI.

[0080] In one embodiment, the control accuracy of the leveling property is 450 DPI.

[0081] In one embodiment, Figure 2 As shown, step S130 includes:

[0082] Step S132, determining the total weight of the spraying material required for printing according to the volume information of the 3D stereoscopic image and the set total spraying thickness information.

[0083] Among them, after the volume information of the 3D stereoscopic image and the set total spraying thickness information are known, combined with the density of the spraying material required for printing (known), the total weight of the spraying material required for printing can be calculated.

[0084] Step S134 , layering the 3D stereoscopic image according to the height information and the total spraying thickness information of the 3D stereoscopic image.

[0085] In order to ensure the printing quality, when 3D printing is performed according to the entire 3D image, it is necessary to print in layers, such as Figure 3 shown.

[0086] In one embodiment, the 3D stereoscopic image is divided into at least three layers according to the height information and the total spraying thickness information of the 3D stereoscopic image.

[0087] Step S136, comprehensively determining the spraying speed, spraying direction, spraying sequence and pre-curing speed according to the slope and area of ​​each diamond surface in each layer and the connection angle information between each diamond surface.

[0088] When determining the spraying speed, spraying direction, spraying sequence and pre-curing speed, it is necessary to comprehensively consider the slope, area and connection angle information of each diamond surface in each layer.

[0089] In one embodiment, the greater the slope of the diamond surface, the lower the spraying speed should be. Under the same spraying speed, the slope itself will increase the flow speed after spraying, and the leveling will be faster (refer to Figure 3 ).

[0090] In one embodiment, the greater the slope of each diamond surface, the spraying direction should be from the top of the slope to the bottom, so as to fully utilize the flow assistance of the slope itself in the spraying process (refer to Figure 3 ).

[0091] In one embodiment, the slopes of the diamond surfaces are different, and the spraying sequence is different. Usually, the plane with a smaller slope is sprayed first, and then the plane with a larger slope is sprayed (refer to Figure 3 ).

[0092] in, Figure 4 The arrow in the figure indicates the spraying direction and also reflects the order of spraying.

[0093] In one embodiment, different slopes of diamond surfaces need to take into account different pre-curing speeds. For example, the greater the slope of the diamond surface, the greater the flow rate of the ink droplets after spraying, and the pre-curing speed needs to be relatively increased.

[0094] In one embodiment, the area of ​​each diamond surface will also affect the spraying speed. If the area is larger, the spraying speed will be relatively increased; if the area of ​​the diamond surface is smaller, the spraying speed will be appropriately reduced.

[0095] In one embodiment, the size of each diamond face will also affect the spraying sequence, for example, the diamond face with a larger area can be sprayed first, and the diamond face with a smaller area can be sprayed later. In one embodiment, the connection angle information between each diamond face will affect the spraying direction and the spraying sequence, for example, the connection angle between each diamond face is relatively gentle, and two adjacent diamond faces can be considered to be sprayed together, and at the same time, the spraying direction is preferably sprayed from top to bottom.

[0096] Step S138, establishing a printing data control model based on the total weight of the spraying material, the total spraying thickness information, the spraying speed, the spraying direction, the spraying sequence and the pre-curing speed.

[0097] In one embodiment, step S134 includes: hierarchically dividing the 3D stereoscopic image into a first layer, a second layer, and a third layer according to the height information and the total spraying thickness information of the 3D stereoscopic image.

[0098] like Figure 4 As shown, the 3D stereoscopic image is hierarchically divided into a first layer P1, a second layer P2 and a third layer P3.

[0099] In this embodiment, the 3D stereoscopic image is hierarchically divided into a first layer, a second layer and a third layer. Since the printing thickness is reduced, the printing parameters can be controlled more accurately, which helps to reduce the overall printing difficulty.

[0100] In one embodiment, Figure 4 As shown, the thicknesses of the first layer, the second layer and the third layer are the same.

[0101] For example, Figure 4 As shown, the thickness of the first layer, the second layer and the third layer can all be set to a thickness of 60MU.

[0102] In one embodiment, before the step of establishing the printing data control model based on the total weight of the spraying material, the total spraying thickness information, the spraying speed, the spraying direction, the spraying sequence and the pre-curing speed, the step further includes:

[0103] Determine the leveling range of each diamond face in each layer;

[0104] The above 3D printing method further includes:

[0105] A printing data control model is established based on the leveling range of each diamond surface in each layer, the total weight of the spraying material, the total spraying thickness information, the spraying speed, the spraying direction, the spraying sequence and the pre-curing speed.

[0106] In this embodiment, the leveling range of each diamond surface needs to meet the preset range, otherwise, the printing quality will not meet the requirements. That is, when establishing the printing data control model, it is necessary to further consider the leveling range of each diamond surface in each layer, the total weight of the spraying material, the total spraying thickness information, the spraying speed, the spraying direction, the spraying order and the pre-curing speed and other factors.

[0107] In one embodiment, Figure 5 As shown, the preset spraying material is resin ink, and step S136 includes:

[0108] Step S136a, determining the distribution arrangement of the resin ink droplets according to the slope and area of ​​each diamond surface in each layer and the connection angle between each diamond surface.

[0109] The slope, area, and connection angle of each diamond surface have a great influence on the distribution and arrangement of resin ink droplets and need to be considered comprehensively.

[0110] For example, for a diamond surface with a larger slope, the ink droplets flow faster after spraying, and the spacing between the ink droplets should be appropriately increased; for a diamond surface with a smaller slope, the ink droplets flow slower after spraying, and the spacing between the ink droplets should be appropriately reduced. In other words, different ink droplet distribution arrangements should be set for diamond surfaces with different slopes.

[0111] Similarly, the areas of different diamond faces are different in size. If the diamond face is larger, the area where the ink droplets are distributed and arranged should increase; if the diamond face is smaller, the area where the ink droplets are distributed and arranged should decrease.

[0112] In addition, the connection angles between the diamond faces are different, so the distribution and arrangement of adjacent ink droplets between two adjacent diamond faces should also be different.

[0113] Step S136b, determining the spraying speed, spraying direction, spraying sequence and pre-curing speed according to the distribution arrangement of the resin ink droplets.

[0114] Among them, the spraying speed, spraying direction and spraying sequence are very likely to affect the distribution arrangement of the resin ink droplets. Therefore, the spraying speed, spraying direction and spraying sequence should be determined according to the distribution arrangement of the resin ink droplets.

[0115] In addition, when the distribution and arrangement of the resin ink droplets form the corresponding diamond spraying plane, they often need to be cured simultaneously. At this time, the curing speed also needs to be controlled synchronously to form a leveling slope.

[0116] In addition, if Figure 6 As shown, a 3D printing device 200 for crystal diamond is also provided, and the 3D printing device 200 includes:

[0117] An image acquisition unit 210 is used to acquire a 3D stereoscopic image of a crystal diamond;
