Problems solved by technology

However, the materials used in traditional 3D printing technology are organic materials such as plastics, photosensitive resins, nylon, paraffin, etc., but cannot be used to form metal parts. Improvement, the traditional laser 3D printing equipment generally includes a laser generator, a laser nozzle, a mechanical arm and a workbench. The function of the laser generator is to generate laser light. The laser nozzle is installed on the robot arm. , longitudinal movement, the entire 3D printing process is completed on the workbench driven by the robotic arm with the laser nozzle
The laser spray head mainly includes a laser head and a powder spray head assembly. The powder spray head assembly only includes a powder spray head. During the molding process, it may be necessary to use different metal powders to print different parts of the metal parts to complete the printing of metal parts with stepped performance materials, or to use different metal powders when printing different metal parts. Obviously, if using the current 3D After the printing equipment completes the above work, the laser nozzle needs to be replaced frequently, which seriously affects the 3D printing effect and reduces the 3D printing efficiency

Abstract

The invention discloses a laser 3D printing device with multiple inkjet heads. The laser 3D printing device with multiple inkjet heads includes a laser generator, a laser inkjet head, a mechanical arm and a working table, wherein the laser inkjet head includes a laser head and a power inkjet head assembly, the power inkjet head assembly comprises a connecting base, a rotating disc and at least two power inkjet heads, the rotating disc is sleeved outside the periphery of the connecting base, the connecting base is provided with a laser through hole which is coaxially communicated with a laser jet hole of the laser head, the at least two power inkjet heads are detachably arranged on the rotating disc and are distributed relative to the periphery of the rotating center of the rotating disc, any power inkjet head is coaxially communicated with the laser jet hole when rotating to a working station, and a fixing unit is arranged between the rotating plate and the connecting base. The laser inkjet head of the laser 3D printing device with the multiple inkjet heads is provided with a plurality of powder inkjet heads and the plurality of powder inkjet heads can be used alternately so that the laser 3D printing device can use a plurality of metal powers to print under the condition that the laser inkjet head is not changed, and the laser 3D printing device meets the 3D printing requirements of FGM (Functionary Gradient Materials) metal pieces.

Description

technical field [0001] The invention relates to a laser 3D printing device, in particular to a multi-nozzle laser 3D printing device. Background technique [0002] 3D printing technology is an emerging forming method, the core of which is to convert the complex 3D shape of the workpiece to be formed into a combination of simple 2D sections through slicing, so it is not necessary to use traditional processing machines and molds. The computer-aided design model, on the computer-controlled rapid prototyping machine, deposits materials layer by layer along the height direction, forming a series of 2D cross-sectional thin sheets of the workpiece, and bonding the sheets to each other, and finally stacking them into a three-dimensional workpiece . However, the materials used in traditional 3D printing technology are organic materials such as plastics, photosensitive resins, nylon, paraffin, etc., but cannot be used for forming metal parts. Improvement, the traditional laser 3D pr...
