Abstract

The invention discloses a plasma cladding manufacturing 3D printing equipment and method. The equipment is composed of a monitoring system, a plasma beam processing system and a horizontal printing platform for placing workpieces to be printed; the plasma beam processing system consists of a plasma generator, It consists of a gas supply device, a powder feeding device that feeds powder into the plasma beam, and a printing position adjustment device; the monitoring system includes a position adjustment controller, a temperature detection unit, a distance detection unit, and a printing distance adjustment controller. The temperature detection unit and the printing distance The temperature control device is composed of an adjustment controller; the method includes steps: 1. acquisition of a three-dimensional model of the workpiece to be printed and layered slice processing; 2. filling of the scanning path; 3. acquisition of the printing path; 4. printing layer by layer from bottom to top. The invention is reasonable in design, easy to operate, high in molding efficiency and good in use effect, does not need a closed molding chamber, and does not need a protective atmosphere or a vacuum environment, and the workpiece molding process is directly carried out in an atmospheric environment.

Description

technical field [0001] The invention belongs to the technical field of rapid prototyping, and in particular relates to a plasma cladding manufacturing 3D printing equipment and 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 breakthr...

This makes SLM rapid prototyping equipment expensive to run

[0007] Third, the laser is the core component of the selective laser rapid prototyping equipment, but the price of the laser is high and the maintenance cost is high

However, the above-mentioned laser cladding molding equipment and method mainly have the following three problems: first, the laser cannot protect the droplet, and a protective gas needs to be passed at the wire feeder. Forming has adverse effects, resulting in low mechanical properties of three-dimensional metal parts; second, the laser power is low and the diameter of the metal wire is large, it is difficult to achieve rapid prototyping of ceramic and composite material parts; third, due to surface tension, droplet cooling Circular shrinkage occurs during solidification molding, resulting in rough surface of the part
