Description

Technical Field

[0001] The utility model relates to the field of bionic support, in particular to a bionic support design structure. Background Art

[0002] 3D printing, also known as additive manufacturing, is a rapid manufacturing technology. Its basic working principle is: first, the digital model is sliced ​​into thin layers through computer-aided design software, and then each layer of material is stacked together layer by layer through a 3D printer to form a complete object. 3D printing uses a variety of materials, including plastics, metals, ceramics, resins, paper, etc. These materials can be customized as needed to produce more precise parts and products. 3D printing technology has been widely used in the medical field, automotive manufacturing, aerospace, construction, and consumer goods manufacturing.

[0003] At present, in the 3D printing process, commonly used support structures include solid support structures, grid support structures, etc. The support structure is usually connected to the printing substrate, and the printed parts are supported by dense grid-like or tree-like entities. After printing is completed, the support structure is removed from the printed parts to obtain independent and complete printed parts.

[0004] However, although solid support structures and grid support structures have relatively good 3D printing stability, their dense solid support structures take a long time to print, extend the production cycle, are extremely difficult to separate from the printed parts, and are not effective in removing powder generated during cutting, resulting in a huge waste of raw material powder. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a bionic support design structure, which aims to solve the problem that the printing of dense solid support structures takes a long time, extends the production cycle, is extremely difficult to separate from the printed parts, and the cleaning effect of the residual traces of the support and the powder after forming is also poor, resulting in a huge waste of raw material powder.

[0006] To achieve the above-mentioned object, the utility model is implemented through the following technical solutions: a bionic support design structure, the bionic support design structure includes a bracket, and a plurality of support components arranged on the bracket;

[0007] A bracket, arranged on the printing substrate, comprises a first frame and a second frame arranged in parallel, and a connecting component for connecting the first frame and the second frame;

[0008] A support assembly, comprising a base, and a first support column and at least two second support columns arranged at one end of the base away from the bracket, wherein one end of the first support column and the second support column are connected to the center of the base;

[0009] Wherein, a plurality of bases are embedded in the first frame, and one end of the first supporting column and the second supporting column away from the base abuts against the printed part.

The first frame is used to embed the support assembly, and the second frame is arranged on the printing substrate. The support assembly includes a base and a first support column and at least two second support columns arranged at one end of the base away from the bracket. One end of the first support column and the second support column is connected to the center of the base, and the other end is tilted to support the printed parts to form a stable support structure. The first frame, the second frame and the support assembly form a lattice structure, which provides a stable support capacity. The hollow design provides a powerful condition for subsequent model cleaning and heat dissipation. At the same time, compared with the traditional support structure, the first support column and the second support column are small in size, the molding process is fast, and the contact area between the support column and the printed parts is small, which is convenient for separation from the printed parts.

[0028] See also Figure 1-Figure 4 , which is a schematic diagram of a bionic support design structure provided in one embodiment of the utility model, the bionic support design structure comprises a support 100 arranged on a printing substrate and a support assembly 200 arranged on a side of the support 100 away from the printing substrate, wherein:

[0029] In order to provide bottom support, a bracket 100 is provided on the printing substrate, and the bracket 100 includes a first frame 110 and a second frame 120 arranged in parallel, and a connecting assembly 130 for connecting the first frame 110 and the second frame 120. In order to improve the structural stability of the bracket 100, in this embodiment, the first frame 110 and the second frame 120 both use regular hexagonal frames of the same size to form a lattice structure.

[0030] In order to connect the support assembly 200, the connection hole 111 includes a first hole portion 112 and a second hole portion 113. The diameter of the second hole portion 113 is larger than that of the first hole portion 112. The second hole portion 113 is used to accommodate one end of the support assembly 200. In order to abut against the support assembly 200, a connection end surface 114 is also provided at the connection between the first hole portion 112 and the second hole portion 113. The connection end surface 114 can be inclined or horizontal. When one end of the support assembly 200 is embedded in the second hole portion 113, the support assembly 200 can be firmly embedded in the support body due to the abutment of the connection end surface 114.

[0031] Furthermore, in order to support the first frame 110 and the second frame 120, the connecting assembly 130 includes a first connecting rod 131 connected to the corner of the first frame 110, and a second connecting rod 132 connected to the corner of the second frame 120, and the connection angle range between the first connecting rod 131 and the second connecting rod 132 is 45°-60°.

[0032] In addition, since the bracket 100 formed by connecting the first frame 110, the second frame 120, the first connecting rod 131 and the second connecting rod 132 is a hollow design, it is convenient to clean the model when it is separated from the printed parts. The powder generated during the cleaning process can be cleaned by high-speed wind or water flow flushing. At the same time, the hollow design can also reduce heat accumulation, speed up the heat dissipation efficiency of the parts, and thus reduce the risk of deformation of the parts due to thermal stress. Since the hollow design of the bracket 100 has fewer entities, the printing cost and printing time are greatly reduced.

[0033] Furthermore, a distance of 3mm-5mm is left between the bracket 100 and the printed part for generating the support assembly 200, which includes a base 210 and a plurality of first support columns 220 and at least two second support columns 230 arranged at one end of the base 210 away from the bracket 100, one end of the first support column 220 and the second support column 230 is connected to the center of the base 210, so that the stress of the end of the first support column 220 and the second support column 230 away from the printed part is concentrated on the base 210, thereby enhancing the structural stability of the support assembly 200 and providing good support capacity for the printed part. Since the diameter of the base 210 is slightly larger than the diameter of the second hole 113, when the base 210 and the second hole 113 are interference-fitted, it can be firmly embedded in the first frame 110, and with the restriction of the connecting end surface 114, it can also avoid falling off from the first frame 110. Compared with the traditional support structure, the first support column 220 and the second support column 230 are small in size, the molding process is fast, and the contact area between the support column and the printed part is small, which is convenient for separation from the printed part.

[0034] According to the above technical solution, the first support column 220 and the second support column 230 are tilted between the base 210 and the printed part. In this embodiment, in a group of support components 200, the number of the first support column 220 is 1, and the number of the second support column 230 is 3, so as to form a conical support structure, and the conical support structure is closely connected with the hexagonal honeycomb support body to improve the support stability. And the length of the first support column 220 is greater than the length of the second support column 230, and the vertical heights of the first support column 220 and the second support column 230 are equal, that is, the first support column 220 and the second support column 230 are tilted on the base 210, and the angle between the first support column 220 and the base 210 is in the range of 35°-60°. The ends of the first support columns 220 away from the first frame 110 extend toward the center of the first frame 110, and are not connected, and are abutted against the bottom of the printed part together to improve the support capacity for the printed part and avoid the phenomenon of the printed part being concave in the middle. It is worth emphasizing that the bionic support design structures in the present application can be used in combination to provide sufficient support force for printed parts.

[0035] In summary, according to a bionic support design structure proposed by the utility model, a base is embedded in the first frame, and one end of the first support column and the second support column are connected to the center of the base, and the other end is tilted to support the printed parts to form a stable support structure. At the same time, the hollow design of the support body is convenient for cleaning the model and heat dissipation. Specifically, the bracket includes a first frame and a second frame arranged in parallel, and a connecting assembly for connecting the first frame and the second frame. The first frame is used to embed the support assembly, and the second frame is arranged on the printing substrate. The support assembly includes a base and a first support column and at least two second support columns arranged at one end of the base away from the bracket. One end of the first support column and the second support column is connected to the center of the base, and the other end is tilted to support the printed parts to form a stable support structure. The first frame, the second frame and the support assembly form a lattice structure, which provides a stable support capacity. The hollow design provides a powerful condition for subsequent model cleaning and heat dissipation. At the same time, compared with the traditional support structure, the first support column and the second support column are small in size, the molding process is fast, and the contact area between the support column and the printed parts is small, which is convenient for separation from the printed parts.
