Embodiment 2

[0168] In this example, if Figure 7 As shown, the difference between the plasma 3D printing equipment used and the embodiment 1 is that the nozzle 13 - 5 and the powder circulation channel 14 are arranged coaxially.

[0169] In this way, after changing the direction of the plasma beam through the nozzle 13-5, the thermal load impact of the plasma jet on the anode nozzle 13-2 can be effectively reduced, and the anode ablation condition is improved. At the same time, since the nozzle 13-5 is coaxially arranged with the powder circulation channel 14, the acceleration, heating and melting process of the powder will not be affected, and the use effect is very good.

[0170] In this embodiment, the structure, connection relationship and working principle of the rest of the plasma 3D printing equipment used are the same as those in Embodiment 1.

[0171] In this embodiment, the plasma 3D printing method adopted is the same as that in Embodiment 1.

Abstract

The invention discloses plasma 3D printing equipment and a 3D printing method. The equipment comprises a monitoring system, a plasma beam processing system, and a plurality of printing platforms. The print platform includes a horizontal printing table, a printing table position adjusting device and an electric running mechanism. The plasma beam processing system consists of a plasma generator, a printing distance adjusting device, a gas supply device and powder feeding device. The monitoring system includes a walking controller, a plurality of walking position detection units, a position adjustment controller, a temperature detection unit, a detection unit and a printing distance adjusting controller. The method comprises the following steps: 1, acquisition of a 3D model of a workpiece to be printed, and hierarchical slicing processing; 2, scanning path filling; 3, printing path acquisition; and 4, printing layer by layer from top to bottom. The invention has the advantages of reasonable design, simple operation, high molding efficiency, good usage effect, no need of enclosed moulding chamber, protection atmosphere or vacuum environment, and direct molding of workpiece in atmosphere environment.

Description

technical field [0001] The invention belongs to the technical field of rapid prototyping, and in particular relates to a plasma 3D printing device and a 3D printing method. Background technique [0002] 3D printing, known as Additive Manufacturing (AM) in academic circles, is a technology that uses computer design data to manufacture physical objects by layer-by-layer accumulation of materials. This technology started from the rapid prototyping technology in the 1980s and has three characteristics: one is a major leap in manufacturing technology. 3D printing is an emerging digital manufacturing technology that was born out of the integration of digital technology and manufacturing technology; the second is a profound change in the manufacturing process. 3D printing has changed the traditional cutting process mode, greatly reduced the processing steps, and can significantly shorten the development cost and cycle of new products; the third is an important breakthrough in the ...
