Abstract
Description
Technical Field
[0001] This utility model relates to the field of building decoration materials technology, specifically a 3D printed building decoration panel. Background Technology
[0002] Currently, 3D printed building decorative panels are mostly used in vertical wall structures. During printing, the 3D printing material medium is filled and printed layer by layer through a pre-set layer height to form a three-dimensional decorative panel.
[0003] The 3D printed decorative panels described above can be further assembled onto a building substrate using snap-fit or adhesive methods to form an integrated building decorative panel for use in subsequent building construction. However, this process adds assembly or bonding steps, and the panels are prone to loosening or falling off after long-term use. Utility Model Content
[0004] To address the technical problems existing in the background art, this utility model provides a 3D printed building decoration panel.
[0005] The technical solution of this utility model is as follows:
[0006] A 3D printed building decorative panel includes a material substrate and a three-dimensional decorative part formed on the surface of the material substrate by 3D printing. The upper surface of the material substrate is roll-pressed with several grooves.
[0007] The groove is V-shaped with the opening facing upwards, and the two opposite sides are the hook-on surfaces;
[0008] The bottom of the groove is V-shaped with the opening facing downwards, and the two opposite sides are inlay surfaces;
[0009] The two ends of the V-shaped opening of the inlay surface are respectively connected to the lower ends of the V-shaped opposite surface of the hanging surface, and the height of the inlay surface is less than the height of the hanging surface.
[0010] The three-dimensional decorative part includes a portion filled in the groove of the material substrate and a portion formed above the horizontal surface of the material substrate. The two parts are integrally formed by 3D printing. The portion formed above the horizontal surface of the material substrate constitutes the three-dimensional decorative pattern of the 3D printed building decorative panel.
[0011] The roughness of the V-shaped opposite surface of the mounting surface is different from the roughness of the inner wall of the inlay surface.
[0012] The roughness of the V-shaped opposite surface of the mounting surface is less than the roughness of the inner wall of the inlay surface.
[0013] The inner wall of the mounting surface is inclined at an angle of 35°-50°.
[0014] The opening angle of the inlay face is 120°-160°.
[0015] The height from the vertex of the mounting surface to the lowest point of the groove is 3-6 times the height from the highest point of the inlay surface to the lowest point of the groove.
[0016] The mounting surface can be symmetrical about the center line, and the inlay surface can be symmetrical about the center line.
[0017] The material of the three-dimensional decorative part is different from the material of the substrate.
[0018] Different three-dimensional decorative parts of different sizes and / or shapes are formed at different groove positions on the same material substrate to create different three-dimensional decorative patterns.
[0019] The same three-dimensional decorative pattern on the same material substrate can cover more than two grooves.
[0020] The beneficial effects of this utility model are:
[0021] 1. Grooves are formed by roll forming during the manufacturing of the material substrate. The process is simple and convenient for wide application.
[0022] 2. The rough design of the inner wall of the groove provides better support for the internal printing material, ensuring the firmness of the internal printing material connection;
[0023] 3. The roughness of the V-shaped opposite surface of the hooking surface is less than the roughness of the inner wall of the inlay surface, which reduces the risk of damage to the material surface by the demolding force during the roll forming process. Attached Figure Description

[0033] Example 1
[0034] The technical solution of this embodiment is as follows:
[0035] refer to Figure 4 and Figure 5 A 3D printed building decorative panel includes a material substrate 3 and a three-dimensional decorative part 2 formed on the surface of the material substrate 3 by 3D printing. Several grooves are rolled on the upper surface of the material substrate 3.
[0036] The groove is V-shaped with the opening facing upwards, and the two opposite sides are the hanging surfaces 301.
[0037] The bottom of the groove is V-shaped with the opening facing downwards, and the two opposite sides are inlay surfaces 302.
[0038] The two ends of the V-shaped opening of the inlay surface 302 are respectively connected to the lower ends of the V-shaped opposite surfaces of the hanging surface 301, and the height of the inlay surface 302 is less than that of the hanging surface 301.
[0039] The three-dimensional decorative part 2 includes a portion that fills the groove in the material substrate 3 and a portion that is formed above the horizontal plane of the material substrate 3. The two parts are integrally formed by 3D printing. The portion formed above the horizontal plane of the material substrate 3 constitutes the three-dimensional decorative pattern of the 3D printed building decorative panel.
[0040] The V-shaped design of the mounting surface 301 provides a mechanical locking function, while the inverted V-shaped design of the inlay surface 302 achieves secondary reinforcement through filling material.
[0041] In this utility model, the grooves of each part can have the same surface roughness, but preferably, the roughness of the V-shaped relative surface of the hanging surface 301 is different from the roughness of the inner wall of the inlay surface 302, and the roughness of the V-shaped relative surface of the hanging surface 301 is less than the roughness of the inner wall of the inlay surface 302.
[0042] The low roughness of the mounting surface 301 reduces the demolding friction during rolling and reduces the risk of material surface damage. The high roughness of the inlay surface 302 enhances the bonding strength of the 3D printed three-dimensional decorative part 2 through the "anchoring effect" and firmly supports the internal material.
[0043] The mounting surface 301 is symmetrical about the center line, and the inlay surface 302 is symmetrical about the center line.
[0044] The symmetrical design ensures that the grooves are subjected to uniform stress, avoiding stress concentration that could lead to cracking.
[0045] Preferably, the inner wall inclination angle of the mounting surface 301 is 35°-50°, the opening angle of the inlay surface 302 is 120°-160°, and the height of the top of the mounting surface 301 reaching the lowest point of the groove is 3-6 times the height of the highest point of the inlay surface 302 reaching the lowest point of the groove. This ensures that the mounting surface 301 preferentially bears the tensile force caused by the weight of the internal material after filling, while the inlay surface 302 bears the shear force. Through precise control of the angle and height ratio, it can adapt to different application requirements.
[0046] The double V-shaped groove design, with the hanging surface 301 and the inlay surface 302 working together, balances ease of installation and connection strength.
[0047] The substrate 3, serving as the main structure of the decorative panel, can be selected from gypsum board, fiberboard, particleboard, etc., and is manufactured using a roll forming process, such as... Figure 2 The diagram shows a single-roller operation mode. During roll forming, the outer surface of the first roller 5 is provided with protrusions. The grooves are formed on the material substrate 3 by roll forming through these protrusions. The roughness of the mounting surface 301 and the inlay surface 302 can be easily differentiated by designing the roughness of different parts of these protrusions differently.
[0048] In this embodiment, the protrusions are arranged in an array around the axis of the first roller shaft 5, and the corresponding central angles are equal. In this case, the grooves of the material substrate 3 are uniform, but a non-uniform arrangement can also be used to adapt to personalized processing needs.
[0049] For some materials, it is also possible to use Figure 3 The double-roller operation shown in this case involves a second roller 6 working in conjunction with the first roller 5, but the outer surface of the second roller 6 is smooth.
[0050] Manufactured using the mature roll forming process described above, this invention expands its application scope in the field of building decoration materials. The roll forming process is characterized by its stability and high production efficiency. Furthermore, the optimized groove structure and its inner wall roughness achieve excellent surface demolding quality and a high yield rate.
[0051] Generally speaking, the material of the substrate 3, as the main material of the building decoration panel, needs to meet general strength requirements, while the material of the three-dimensional decorative part 2 mainly serves a decorative function. Therefore, the material of the three-dimensional decorative part 2 can be different from the material of the substrate 3. For example, when gypsum is used as the base material, the material of the three-dimensional decorative part 2 does not need to be reinforced with reinforcing materials such as reinforcing fibers.
[0052] In another embodiment of this utility model, three-dimensional decorative parts 2 of different sizes and / or shapes can be formed at different corresponding positions of the grooves on the same material substrate 3 to construct different three-dimensional decorative patterns, such as... Figure 6 As shown.
[0053] In another embodiment of this utility model, the same three-dimensional decorative pattern on the same material substrate 3 can also cover two or more grooves, such as... Figure 7 As shown.
[0054] When using material substrate 3, such as Figure 1 The ungrooved side is placed on the printing platform, and the 3D printer program is set to start printing. When the print head 1 reaches the groove position, it fills the groove first, and then continues printing the remaining three-dimensional decorative part 2. After printing, wait for the three-dimensional decorative part 2 to set to obtain the product. When the product is set, it can be fixed to a building, such as a wall, using expansion screws, or it can be glued to the building in other ways.
