Embodiment 1

[0040] The three-dimensional digital model of the thin-walled partition parts involved in this embodiment is as follows figure 1 As shown, the material is aluminum alloy, and the forming method is SLM additive manufacturing. After analysis, the size of the part is 220×200×80mm, the thickness of the thin-walled partition is 1mm, and the length of the thin-walled partition is about 100mm. It belongs to a V-shaped part. During the forming process of the thin-walled structure, it is easy to deform and the knife gets stuck, which makes it difficult to form the part. .

[0041] Using the deformation control method for additive manufacturing of thin-walled partition parts of the present application, the steps are as follows:

[0042] S1. Determine the placement of the parts, and determine the growth direction of the parts to be parallel to each thin-walled partition. The 2D profile of a single-layer sintered part as figure 2 As shown, there is no constraint on the position of the...

Embodiment 2

[0047] The three-dimensional digital model of the thin-walled partition parts involved in this embodiment is as follows Figure 5 As shown, the material is titanium alloy, and the forming method is SLM additive manufacturing. After analysis, the size of the part is 300×300×50mm, the thickness of the thin-walled blade is 2mm, and the length of the thin-walled blade is about 130mm. It belongs to a V-shaped part. The stress in the forming process of titanium alloy is large, and the thin-walled structure is easy to deform and jam during the forming process. , making the parts difficult to shape.

Description

technical field [0001] The present application relates to the technical field of advanced laser additive manufacturing, in particular to a deformation control method for additive manufacturing of thin-walled partition parts. Background technique [0002] Additive Manufacturing (AM), also known as 3D printing, is an advanced manufacturing technology that combines computer graphics processing, digital information and control, laser technology and material technology. After designing the three-dimensional model of the part, add Support, and then layered and sliced ​​into two-dimensional graphics, the powder is melted layer by layer through the laser beam, and the layers are stacked to complete the manufacturing of the three-dimensional solid model. [0003] Many thin-walled components have complex structures, and cannot be processed by conventional sheet metal, machining, welding and other processes. Laser 3D printing must be used to form them. However, additive manufacturing i...
