Embodiment Construction

[0018] Such as figure 1 as shown, figure 1 It is a schematic flow chart of the 3D printing method of the present invention. The 3D printing method comprises the following steps:

[0019] Step a: providing a liftable printing platform.

[0020] Step b: controlling the printing platform to descend by a first predetermined distance, and spreading metal printing powder on the printing platform.

[0021] It should be understood that the first predetermined distance value is a set value, which can be set on the printer according to actual needs.

[0022] It is worth noting that if figure 2 As shown, in some embodiments, the metal printing powder includes a first metal printing powder and a second metal printing powder, and the printing platform includes a first printing area 10 and a second printing area 11 . Wherein the step b of controlling the printing platform to drop the first predetermined distance value, and laying metal printing powder on the printing platform includes...

Abstract

The invention discloses a 3D printing method, comprising: step a: providing a liftable printing platform; step b: controlling the printing platform to descend a first predetermined distance value, and spreading metal printing powder on the printing platform; step c : controlling the first laser head to emit a laser with a first predetermined energy value towards the metal printing powder on the printing platform to melt the metal printing powder to form a printing object; step d: controlling the second laser head to rotate around the printing object, and simultaneously controlling The second laser head emits laser light with a second predetermined energy value toward the edge of the printed object on the printing platform to eliminate particles on the edge of the printed object, and the wavelength of the laser light corresponding to the first predetermined energy value is shorter than that specified by the second predetermined energy value. The wavelength of the corresponding laser light is short. Through the above method, the present invention eliminates the particles on the edges of each layer of printed objects each time a layer of printed objects is formed on the printing platform, so that the outer surface of the printed object is not rough and feels good.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing method. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital files, using powder or curable materials, and manufacturing products by layer-by-layer printing. It is in sharp contrast to the subtractive manufacturing technology used in traditional manufacturing. In contrast, 3D printing is an additive manufacturing technology that forms the final product by superimposing layers of materials. [0003] At present, the outer surface of printed objects printed by 3D printing methods on the market is rough, and there are even grainy spots, and the hand feeling of people is very poor. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide a 3D printing method. By forming a layer of printed objects on the printing powder of the printing platform e...
