Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, specifically to a large-size laser-printed support structure that is resistant to deformation. Background Technology

[0002] With the continuous development of the manufacturing industry, metal 3D printing technology has received widespread attention and application in fields such as aerospace, automotive, and machinery manufacturing. The demand for laser 3D printing of large-size metal components is increasing. However, during the printing process, the metal material undergoes complex thermal stress and deformation problems during high-temperature melting, solidification, and subsequent cooling, which seriously affects the dimensional accuracy and quality of the printed parts.

[0003] Traditional metal 3D printing support structures are mostly straight column structures. While straight column supports can prevent structural deformation and collapse to some extent, they are not effective at resisting warping, twisting, and other deformations caused by complex thermal stresses, and cannot meet the high precision requirements of large-sized components. In addition, traditional support structures are tightly connected to the product, making them difficult to separate. Utility Model Content

[0004] The purpose of this invention is to provide a large-size laser-printed support structure that is resistant to deformation, so as to solve the problem that existing support structures relying solely on independent support columns are prone to large deformations.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] A deformation-resistant large-size laser printing support structure includes a support structure body disposed between a support platform and a product. The support structure body includes a grid support component. The grid support component has a support block at one end near the support platform and a dot matrix connector at one end near the product.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions:

[0008] In one alternative: the supporting structure body is composed of multiple space frame support components stacked vertically, with an intermediate platform between the space frame support components, and the intermediate platform is fixedly connected to the space frame support components above and below.

[0009] In one alternative: the space frame support assembly includes several support columns, each support column is provided with a first connecting sphere, and the support columns are provided with second connecting spheres, which are connected to the first connecting spheres by connecting rods.

[0010] In one alternative: the height of a single space frame support component is 5-10cm.

[0011] In one alternative: an isolation layer is provided at the lower end of the support block.

[0012] In one alternative: the thickness of the isolation layer is 1-5 mm.

[0013] In one alternative: the fill rate of each layer of the isolation layer gradually decreases from bottom to top.

[0014] In one alternative: the dot matrix connector consists of several diagonal bars arranged in an alternating pattern.

[0015] This utility model has the following beneficial effects:

[0016] This utility model forms a grid structure by means of support columns, a first connecting sphere, a second connecting sphere, and connecting rods. The multi-point constraint effect of the grid structure disperses stress and improves the overall rigidity of the support structure, thereby improving the deformation resistance of the support structure. At the same time, the setting of isolation layer and dot matrix connectors makes it easy for the support structure to be separated from the support platform and the product.

Detailed Implementation

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] like Figs. 1 to 3As shown, this embodiment provides a large-size laser printing support structure with resistance to deformation, including a support structure body 300 disposed between a support platform 100 and a product 200. The support structure body 300 includes a space frame support assembly 400. A support block 600 is provided at one end of the space frame support assembly 400 near the support platform 100, and a dot matrix connector 700 is provided at the other end of the space frame support assembly 400 near the product 200. The stress is dispersed through the multi-point constraint effect of the space frame support assembly 400, which significantly improves the overall rigidity and reduces the deformation of the product 200. The dot matrix connector 700 facilitates the separation of the space frame support assembly 400 from the product 200.

[0023] The supporting structure body 300 is composed of multiple vertically stacked space frame supporting components 400. An intermediate platform 500 is provided between the space frame supporting components 400. The intermediate platform 500 is fixedly connected to the space frame supporting components 400 above and below. The space frame supporting component 400 includes several supporting columns 401. A first connecting ball 402 is provided on the supporting column 401. A second connecting ball 403 is provided between the supporting columns 401. The second connecting ball 403 is connected to the first connecting ball 402 through a connecting rod 404. The height of a single space frame supporting component 400 is 5-10cm. The space frame structure formed by the supporting columns 401, the first connecting ball 402, the second connecting ball 403 and the connecting rod 404 disperses stress through the multi-point constraint effect of the space frame structure, thereby improving the overall rigidity of the supporting structure body 300.

[0024] The lower end of the support block 600 is provided with an isolation layer 601. The thickness of the isolation layer 601 is 1-5mm. The filling rate of each layer of the isolation layer 601 gradually decreases from bottom to top. By setting the isolation layer 601, the support block 600 and the support platform 100 can be easily separated.

[0025] The dot matrix connector 700 is composed of several staggered diagonal bars 701, which can reduce the amount of support material used while ensuring sufficient support strength, and is also easy to remove after printing.

[0026] The above embodiments disclose a large-size laser printing support structure with resistance to deformation. A grid structure is formed by support columns 401, first connecting spheres 402, second connecting spheres 403 and connecting rods 404. The multi-point constraint effect of the grid structure disperses stress and improves the overall rigidity of the support structure body 300, thereby improving the deformation resistance of the support structure. At the same time, the setting of the isolation layer 601 and the dot matrix connectors 700 makes it easy for the support structure body 300 to be separated from the support platform 100 and the product 200.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
