Description

Technical Field

[0001] Multiple embodiments of this specification relate to the field of printing technology, and specifically to a method and device for printing a special-shaped enclosure wall, and a method and device for printing a special-shaped dam. Background Art

[0002] The application of the enclosure structure printing technology is currently quite extensive. Especially in the edge area of the display module, the application of dam printing is particularly important (the dam is the middle frame structure). This dam design provides effective dust, water, and anti-collision protection for the circuit in the display module, improving the overall protection performance of the device.

[0003] In the field of electronic devices, such as mobile phones and tablet computers, in order to improve the aesthetics and feel of the product, the side of the outer shell is often designed with an arc. However, the dam structure on the internal circuit board is usually vertically arranged, and this design is difficult to perfectly fit the arc contour of the outer shell, thus forming a gap between the two. The existence of these gaps limits the effect of the dam structure in terms of dust, water, and anti-collision. Therefore, the need for printing special-shaped enclosure structures has emerged, especially the need to apply the printing of special-shaped enclosure structures to dam structure printing.

[0004] Furthermore, for a special-shaped enclosure structure, the reduction degree of the final printed shape to the designed shape is crucial for the application of the product. For example, inside a mobile phone and a tablet computer, if the dam structure can achieve a higher degree of fit with the outer shell, it will significantly improve its protection performance, thereby ensuring the stable operation of the device in a complex environment.

[0005] In view of this, there is an urgent need for a method that can accurately print a special-shaped enclosure structure. Summary of the Invention

[0049] Seventh aspect, an embodiment of this specification provides a computer storage medium, which stores multiple instructions, and the instructions are suitable for being loaded and executed by a processor to execute the steps described in the first aspect or the second aspect of the above embodiments.

[0050] The beneficial effects brought by the technical solutions provided by some embodiments of this specification at least include:

[0051] Based on the layer height information and the enclosure routes corresponding to each enclosure layer, a special-shaped enclosure wall is printed by means of layer-by-layer stacking. During the printing process of the special-shaped enclosure wall, there is no step of adjusting the angle of the printing surface in the pitch angle direction and the roll angle direction. It not only provides a printing solution for the special-shaped enclosure wall, but also avoids the angle adjustment calculation of the printing surface in the pitch angle direction and the roll angle direction during the printing process. The angle adjustment calculation in these two directions for adapting to the shape change of the special-shaped enclosure wall is relatively complex and prone to errors. Therefore, the printing solution for the special-shaped enclosure wall provided by the embodiments of this specification can improve the printing accuracy of the special-shaped enclosure wall.

[0052] Since there is no step of adjusting the angle of the printing surface in the pitch angle direction and the roll angle direction during the printing process of the special-shaped enclosure wall by means of layer-by-layer stacking, when printing the upper enclosure layer in real time, the printing material of the upper enclosure layer may be partially suspended above the printing material of the lower enclosure layer. If timely curing operation is not performed, the deformation problem of the printing material will be relatively serious, resulting in a deviation between the final printed shape of the special-shaped enclosure wall and the desired designed shape. Therefore, during the printing process of the special-shaped enclosure wall, a synchronous curing operation is performed on the printing line in real time to improve the stability of the special-shaped enclosure wall, and thus improve the reduction degree of the shape of the special-shaped enclosure wall.

[0053] The enclosure route of the bottommost enclosure layer in the horizontal direction can be known in advance according to the printing requirements, and the vector information of the extension directions corresponding to each adjacent two enclosure layers can also be known in advance based on the design parameters of the special-shaped enclosure wall. Further, based on the floor height information corresponding to each enclosure layer, the vector information of the extension directions corresponding to each adjacent two enclosure layers, and the enclosure route of the bottommost enclosure layer in the horizontal direction, the enclosure routes corresponding to each enclosure layer in the horizontal direction can be obtained. Moreover, the enclosure routes corresponding to each enclosure layer in the horizontal direction obtained in this way are more accurate, further improving the restoration degree of the shape of the special-shaped enclosure wall.

[0054] To adapt to the design requirements of the application products of the special-shaped enclosure wall, there may be slight height differences at different positions on the top contour line of the special-shaped enclosure wall; in addition, there may also be slight height differences at different positions on the printing surface. Therefore, it is necessary to perform hierarchical processing on the three-dimensional space model in the vertical direction based on the first height data set of the top contour line of the three-dimensional space model and / or the second height data set of the bottom contour line of the three-dimensional space model to obtain a plurality of enclosure layers stacked in sequence from bottom to top, so as to achieve a more reasonable hierarchical operation.

Detailed implementation manner

[0071] Next, the technical solutions in the embodiments of this specification will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this specification.

[0072] The terms "first", "second", "third", etc. in the specification, claims and the above-mentioned drawings of this specification are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.

[0073] The following description provides examples and does not limit the scope, applicability or examples set forth in the claims. Changes can be made to the functions and arrangements of the described elements without departing from the scope of the content of this specification. Each example can appropriately omit, substitute or add various processes or components. For example, the described method can be executed in a different order from the described order, and various steps can be added, omitted or combined. In addition, the features described in some examples can be combined into other examples.

[0074] Refer to Figure 1 as shown Figure 1 which is a schematic flowchart of a method for printing a special-shaped enclosure wall provided by an embodiment of this specification. The method for printing a special-shaped enclosure wall can at least include:

[0075] Step 102: Obtain a three-dimensional space model of the special-shaped enclosure wall, and perform layering processing on the three-dimensional space model in the vertical direction to obtain a plurality of enclosure layers 3 stacked in sequence from bottom to top, and obtain the floor height information corresponding to each enclosure layer 3 (note: the floor height represents the height of the enclosure layer 3 in the vertical direction);

[0076] Step 104: Obtain the enclosure routes of each enclosure layer 3 in the horizontal direction, and at least one pair of adjacent enclosure layers 3 among the plurality of enclosure layers 3 stacked in sequence from bottom to top have deviation in the enclosure routes in the horizontal direction;

[0077] Step 106: Based on the floor height information corresponding to each enclosure layer 3 and the enclosure route corresponding to each enclosure layer 3, use the print head to print multiple enclosure layers 3 on the printing surface 1 in a stacked manner from bottom to top to print a special-shaped enclosure wall. During the process of printing the special-shaped enclosure wall, there is no step of adjusting the angle of the printing surface 1 in the pitch angle direction and the roll angle direction.

[0078] It should be noted that by adjusting the angle of the printing surface 1 in the pitch angle direction and the roll angle direction, the printing of a special-shaped enclosure wall can be achieved (note: by changing the angle of the printing surface 1 in the pitch angle direction and the roll angle direction, the angle between the print head and the horizontal plane can be changed, thereby achieving the printing of a special-shaped enclosure wall), and the adhesion of the upper enclosure layer to the lower enclosure layer can be better ensured (note: the upper enclosure layer can be completely attached to the lower enclosure layer, thereby avoiding the upper enclosure layer being partially suspended above the lower enclosure layer). However, the computational complexity of this angle adjustment is relatively high, so errors are likely to occur and the errors are relatively large.

[0079] In the method for printing a special-shaped enclosure wall provided by multiple embodiments of this specification, based on the floor height information corresponding to each enclosure layer 3 and the enclosure route corresponding to each enclosure layer 3, a special-shaped enclosure wall is printed by means of layer-by-layer stacking printing. During the process of printing the special-shaped enclosure wall, there is no step of adjusting the angle of the printing surface 1 in the pitch angle direction and the roll angle direction. The printing of the special-shaped enclosure wall is achieved only by controlling the translation and height adjustment of the printing surface 1 and / or the print head (note: at most, an angle adjustment in the yaw angle direction of the printing surface 1 is added). Therefore, not only a printing solution for the special-shaped enclosure wall is provided, but also the calculation of the adjustment angle of the printing surface 1 in the pitch angle direction and the roll angle direction is avoided during the printing process. Therefore, the printing solution for the special-shaped enclosure wall provided by the embodiments of this specification can improve the printing accuracy of the special-shaped enclosure wall and improve the reduction degree of the shape of the special-shaped enclosure wall.

[0080] It should also be noted that during the printing process, in addition to printing along the enclosure route corresponding to each enclosure layer 3 in the horizontal direction, it is also necessary to combine the floor height information corresponding to each enclosure layer 3 to control the printing height when printing each enclosure layer 3.

[0081] In multiple embodiments of this specification, during the process of printing a special-shaped enclosure wall, a synchronous curing operation is performed on the printing line in real time.

[0082] Since there is no step of adjusting the angle of the printing surface 1 in the pitch angle direction and the roll angle direction during the process of printing the special-shaped enclosure wall in a stacked manner, when printing the upper enclosure layer in real time, the printing material of the upper enclosure layer may be partially suspended above the printing material of the lower enclosure layer (Note: because the upper enclosure layer may have a position offset in the horizontal direction compared with the lower enclosure layer). If timely curing operation is not carried out, the deformation problem of the printing material will be relatively serious, which will lead to a deviation between the final printed shape of the special-shaped enclosure wall and the desired designed shape. Therefore, during the process of printing the special-shaped enclosure wall, the printing line is synchronously cured in real time to improve the stability of the special-shaped enclosure wall, and thus the shape reduction degree of the special-shaped enclosure wall is improved.

[0083] Referring to Figure 2 As shown, in multiple embodiments of this specification, obtaining the enclosure routes of each enclosure layer 3 corresponding to each other in the horizontal direction includes:

[0084] Step 202, obtaining the enclosure route of the bottommost enclosure layer 3 in the horizontal direction (establishing a plane coordinate system with the printing surface 1 as the horizontal plane, and each position on the enclosure route has a corresponding position coordinate in this plane coordinate system);

[0085] Step 204, obtaining the respective corresponding extension direction vector information between each two adjacent enclosure layers 3, where the extension direction vector information includes multiple extension direction vectors that can reflect the respective extension conditions of the enclosure surface composed of two adjacent enclosure layers 3 at multiple extension positions (Note: Refer to Figure 3 , Figure 4 As shown, there are multiple extension lines 2 from bottom to top in a whole enclosure wall. The extension direction vector represents the vector of the extension condition between a certain two adjacent enclosure layers 3, which is a part of the extension line 2. The extension direction vector can be referred to Figure 6 As shown. It should be noted that the extension direction vector can be obtained according to the design parameters of the special-shaped enclosure wall);

[0086] Step 206, based on the respective corresponding layer height information of each enclosure layer 3, the respective corresponding extension direction vector information between each two adjacent enclosure layers 3, and the enclosure route of the bottommost enclosure layer 3 in the horizontal direction, obtaining the enclosure routes of each enclosure layer 3 corresponding to each other in the horizontal direction (Note: The specific calculation principle will be explained in detail in the following embodiments).

[0087] It should be added that Figure 3 and Figure 4 show a special-shaped situation of the special-shaped enclosure wall, Figure 5 show another special-shaped situation of the special-shaped enclosure wall.

[0088] Among them, Figure 3 andFigure 4 The shown special-shaped retaining wall is a frustum-shaped cylindrical structure that contracts inward as a whole. Figure 5 The special-shaped retaining walls shown have varying degrees of inclination along the retaining route. That is, the method for printing special-shaped retaining walls described in multiple embodiments of this specification can print special-shaped retaining wall structures of various styles.

[0089] Refer to Figure 7 As shown, in multiple embodiments of this specification, obtaining the retaining route of each retaining layer 3 in the horizontal direction based on the respective corresponding height information of each retaining layer 3, the respective corresponding extension direction vector information between each two adjacent retaining layers 3, and the retaining route of the lowermost retaining layer 3 in the horizontal direction includes:

[0090] Step 702: Consider the lowermost retaining layer 3 among all retaining layers 3 as the lower retaining layer, and consider the upper retaining layer 3 of the lowermost retaining layer 3 among all retaining layers 3 as the upper retaining layer;

[0091] Step 704: Based on the retaining route of the current lower retaining layer, the corresponding extension direction vector information between the current lower retaining layer and the current upper retaining layer, the height information corresponding to the current lower retaining layer, and / or the height information corresponding to the current upper retaining layer, obtain the retaining route of the current upper retaining layer;

[0092] Step 706: When the retaining layer 3 for which the retaining route is newly obtained is not the topmost retaining layer among all retaining layers 3, consider the retaining layer 3 for which the retaining route is newly obtained as the new lower retaining layer, consider the upper retaining layer 3 of the retaining layer 3 for which the retaining route is newly obtained as the new upper retaining layer, and return to the step of obtaining the retaining route of the current upper retaining layer based on the retaining route of the current lower retaining layer, the corresponding extension direction vector information between the current lower retaining layer and the current upper retaining layer, the height information corresponding to the current lower retaining layer, and / or the height information corresponding to the current upper retaining layer.

[0093] It should be noted that the retaining route of the lowermost retaining layer 3 among all retaining layers 3 can be obtained based on the actual installation position of the special-shaped retaining wall on the printing surface 1. Further, the retaining routes corresponding to each retaining layer 3 can be obtained in sequence by successive recursion.

[0094] Refer to Figure 8 As shown, in multiple embodiments of this specification, obtaining the retaining route of the current upper retaining layer based on the retaining route of the current lower retaining layer, the corresponding extension direction vector information between the current lower retaining layer and the current upper retaining layer, the height information corresponding to the current lower retaining layer, and / or the height information corresponding to the current upper retaining layer includes:

[0095] Step 802: Based on the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer, the layer height information corresponding to the current lower enclosure layer, and / or the layer height information corresponding to the current upper enclosure layer, calculate the horizontal offset direction and offset distance corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the current upper enclosure layer;

[0096] Step 804, based on the position coordinates corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer and the calculated offset directions and offset distances in the horizontal direction corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the upper enclosure layer, obtain the enclosure route of the current upper enclosure layer.

[0097] Please refer to Figure 3 As shown, the special-shaped enclosure wall has corresponding extension lines 2 at different positions (Note: the extension line 2 can show the shape change of the special-shaped enclosure wall in the height direction, and Figure 3 Only 8 extension lines are shown as an example), so for the two enclosure layers 3 distributed up and down, there are also multiple extension direction vectors at different positions of the two.

[0098] Furthermore, based on the corresponding extension direction vector information between the lower enclosure layer and the upper enclosure layer, the layer height information corresponding to the current lower enclosure layer, and the layer height information corresponding to the current upper enclosure layer, the horizontal offset direction and offset distance corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the current upper enclosure layer can be calculated (Note: the specific calculation principle is explained in the following embodiments).

[0099] Reference Figure 9 As shown, in multiple embodiments of the present specification, based on the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer, the layer height information corresponding to the current lower enclosure layer and / or the layer height information corresponding to the current upper enclosure layer, the offset direction and offset distance in the horizontal direction corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the current upper enclosure layer are calculated, including:

[0100] Step 902: Based on the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer, obtain the horizontal components of the multiple extension direction vectors in the corresponding extension direction vector information between the current lower enclosure layer and the current upper enclosure layer and the angles with the horizontal plane;

[0101] Step 904, based on the horizontal components in the horizontal direction and the angles with the horizontal plane of multiple extension direction vectors in the extension direction vector information corresponding to the current lower enclosure layer and the current upper enclosure layer, the layer height information corresponding to the current lower enclosure layer and / or the layer height information corresponding to the current upper enclosure layer, calculate the horizontal offset directions and offset distances corresponding to multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the current upper enclosure layer.

[0102] Reference Figure 6 As shown, Figure 6 The calculation principle of calculating the horizontal offset direction and offset distance corresponding to a certain enclosure position on the enclosure route of the lower enclosure layer required for obtaining the enclosure route of the upper enclosure layer is exemplified:

[0103] First, according to the design parameters of the special-shaped retaining wall, we can obtain Figure 6 The extension direction vector between the middle and lower enclosure layers and the upper enclosure layer, and then the horizontal component of the extension direction vector is obtained. Based on the horizontal component of the extension direction vector, the horizontal offset direction of the upper enclosure layer compared to the lower enclosure layer can be known;

[0104] Furthermore, the angle θ between the extension direction vector and the horizontal plane can be known according to the extension direction vector;

[0105] Furthermore, the height difference △H between the upper enclosure layer and the lower enclosure layer is obtained (Note: Figure 6 The height difference △H of the enclosure layer is calculated based on the middle position of the enclosure layer height. Therefore, when the upper enclosure layer height is consistent with the lower enclosure layer height, the enclosure layer height difference △H can be considered as the upper enclosure layer height or the lower enclosure layer height. When the upper enclosure layer height is inconsistent with the lower enclosure layer height, the enclosure layer height difference △H can be considered as the average value of the sum of the upper enclosure layer height and the lower enclosure layer height; when the enclosure layer height difference △H is calculated based on the top of the enclosure layer, the enclosure layer height difference △H can be directly considered as the upper enclosure layer height);

[0106] Finally, the horizontal offset distance △L of the upper enclosure layer compared to the lower enclosure layer can be obtained based on the angle θ and the enclosure layer height difference △H.

[0107] According to the above logic, the horizontal offset direction and offset distance corresponding to each of the multiple enclosure positions on the enclosure route of the current lower enclosure layer required to obtain the enclosure route of the current upper enclosure layer can be calculated. Therefore, based on the enclosure route of the lower enclosure layer, the enclosure route of the upper enclosure layer can be obtained.

[0108] In addition, it can also be understood that, in order to avoid excessive overhanging of the upper retaining wall layer outside the lower retaining wall layer, in multiple embodiments of this specification: for any pair of adjacent retaining wall layers 3, the offset distance △L corresponding to any retaining position on the lower retaining wall layer in the horizontal direction is less than a preset threshold, and the preset threshold can be a preset proportional size of the width of the lower retaining wall layer.

[0109] Therefore, based on the above calculation principle, for any pair of adjacent retaining wall layers 3, the height difference between adjacent two retaining wall layers 3 and the angle θ between any retaining position on the lower retaining wall layer and the horizontal plane should both meet the following conditions:

[0110] The height difference △H of the retaining wall layer / tanθ ≤ the preset threshold, and the preset threshold can be set according to the width condition of the lower retaining wall layer.

[0111] In multiple embodiments of this specification, before performing layer-by-layer processing on the three-dimensional space model in the vertical direction to obtain multiple retaining wall layers 3 stacked in sequence from bottom to top and obtaining the floor height information corresponding to each retaining wall layer 3, it further includes:

[0112] Obtaining a first height data set of the top contour line of the three-dimensional space model and / or a second height data set of the bottom contour line of the three-dimensional space model, where the first height data set includes the height data corresponding to each contour point on the top contour line of the three-dimensional space model, and the second height data set includes the height data corresponding to each contour point on the bottom contour line of the three-dimensional space model;

[0113] The performing layer-by-layer processing on the three-dimensional space model in the vertical direction to obtain multiple retaining wall layers 3 stacked in sequence from bottom to top includes:

[0114] Based on the first height data set of the top contour line of the three-dimensional space model and / or the second height data set of the bottom contour line of the three-dimensional space model, performing layer-by-layer processing on the three-dimensional space model in the vertical direction to obtain multiple retaining wall layers 3 stacked in sequence from bottom to top.

[0115] Refer to Figure 4 As shown, in order to adapt to the application product design requirements of the special-shaped retaining wall, there may be slight height differences at different positions on the top contour line of the special-shaped retaining wall; in addition, there may also be slight height differences at different positions on the printing surface 1. Therefore, it is necessary to perform layer-by-layer processing on the three-dimensional space model in the vertical direction based on the first height data set of the top contour line of the three-dimensional space model and / or the second height data set of the bottom contour line of the three-dimensional space model to obtain multiple retaining wall layers 3 stacked in sequence from bottom to top to achieve a more reasonable layer-by-layer operation.

[0116] Therefore, in one embodiment of this specification, obtaining the three-dimensional space model of the special-shaped retaining wall includes:

[0117] Obtain the design parameters of the special-shaped enclosure wall;

[0118] Obtain the enclosure route of the bottom of the special-shaped enclosure wall on the printing surface, and obtain the height data situation at the enclosure route of the bottom of the special-shaped enclosure wall on the printing surface 1;

[0119] Based on the height data situation at the enclosure route of the bottom of the special-shaped enclosure wall on the printing surface 1 and the design parameters of the special-shaped enclosure wall, obtain the three-dimensional space model of the special-shaped enclosure wall.

[0120] Specifically, referring to Figure 4 、 Figure 10 As shown, perform a hierarchical processing on the three-dimensional space model in the vertical direction based on the first height data set of the top contour line of the three-dimensional space model and / or the second height data set of the bottom contour line of the three-dimensional space model, to obtain a plurality of stacked enclosure layers 3 from bottom to top, including:

[0121] Step 1002: Obtain a plurality of extension lines 2 that can reflect the respective extension situations in the height direction at different positions of the three-dimensional space model;

[0122] Step 1004: Obtain the height data of the contour points 21 on the top contour line of the three-dimensional space model and / or the height data of the contour points 22 on the bottom contour line of the three-dimensional space model corresponding to each extension line 2;

[0123] Step 1006: Based on the height data of the contour points 21 on the top contour line of the three-dimensional space model and / or the height data of the contour points 22 on the bottom contour line of the three-dimensional space model corresponding to each extension line 2, perform a segmentation process on each extension line 2 respectively, to obtain a plurality of segmentation points 23 corresponding to each extension line 2;

[0124] Step 1008: Obtain the layer data of all the segmentation points 23 corresponding to their positions on the respective extension lines 2;

[0125] Step 1010: Based on the layer data of all the segmentation points 23 corresponding to their positions on the respective extension lines 2, perform a connection operation on the segmentation points 23 belonging to the same layer respectively, to obtain a plurality of layer lines 24 of the three-dimensional space model (note: it can be understood that perform a fitting connection operation on all the segmentation points 23 located on the first layer, perform a fitting connection operation on all the segmentation points 23 located on the second layer, and so on);

[0126] Step 1012: Perform a hierarchical processing on the three-dimensional space model in the vertical direction based on the plurality of layer lines 24 of the three-dimensional space model, to obtain a plurality of stacked enclosure layers 3 from bottom to top.

[0127] Based on the height data of the contour points 21 corresponding to each extension line 2 on the top contour line of the three-dimensional space model and / or the height data of the contour points 22 on the bottom contour line of the three-dimensional space model, each extension line 2 is segmented respectively to obtain multiple segmentation points 23 corresponding to each extension line 2. Any one of the following several modes can be adopted, but is not limited to:

[0128] Mode 1: For each extension line 2, it is divided into the same number of segments. And for the same extension line 2, the height difference between any two adjacent segmentation points 23 thereon is the same. For different extension lines 2, the height differences between adjacent segmentation points 23 may be different. In this mode, the entire special-shaped enclosure wall can be completely divided into multiple enclosure layers 3 without any redundant structure. Therefore, continuous printing of the entire special-shaped enclosure wall can be achieved. However, it should be noted that in this mode, since the floor heights at various positions of the enclosure layer 3 may be inconsistent, the printing parameters may need to be adjusted in real time when printing each enclosure layer 3 (Note: In this mode, the obtained floor height information of the enclosure layer needs to include the floor height information corresponding to each enclosure position of the enclosure layer).

[0129] Mode 2: A preset height is set, and each extension line 2 is segmented respectively based on this preset height. Therefore, for all extension lines 2, the height difference between any two adjacent segmentation points 23 is the preset height. In this mode, during the printing process of each enclosure layer 3, the floor heights at all positions of the enclosure layer 3 are the same. Therefore, continuous printing of the enclosure layer 3 can be achieved. However, it should be noted that in this mode, there may be some parts at the top of each extension line 2 that do not reach the preset height, so they need to be printed separately.

[0130] In addition to the above two modes, there are also many other layering modes, which can be specifically set according to the printing requirements and will not be elaborated here one by one.

[0131] It should also be noted that the control of the floor height of the enclosure layer 3 can be achieved by adjusting the material discharge speed of the print head, the moving speed of the print head and / or the printing surface 1.

[0145] Step 7: Successively use the special-shaped retaining wall printing method described in the above embodiments to print the outer dam 4 and the inner dam 5 on the display screen.
