Original Title [Scientific and Technological Achievements Push] Shanghai Academy of Sciences Laser Coaxial Fuse ?Industrial Metal 3D Printing Technology -Shanghai Academy of Sciences- Project name Laser coaxial fuse Industrial metal 3D printing technology 01 Project background Industrial metal 3D printing technology is an important direction of intelligent manufacturing and additive manufacturing in the future At present most of the mature metal printing equipment in the domestic and foreign markets are based on powder as consumables but this technology is suitable for printing small and precise titanium tubing price metal parts and the material loss is large and the efficiency is low The development and application of industrial metal wire 3D printing technology overcomes the above defects of powder printing and is more suitable for the printing and manufacturing of large metal parts with obvious advantages 02 The unit to which the titanium exhaust tubing project belongs Shanghai Academy of Sciences 03 Project introduction At present the 3D printing technologies using metal wires at home and abroad mainly include arc deposition forming electron beam paraxial wire feeding and laser paraxial wire feeding which are compared with our laser coaxial fuse metal 3D printing technology as shown in the following figure Laser coaxial fuse metal 3D printing technology its principle is to first expand the laser beam then shape to the annular laser beam then focus the annular laser the metal wire passes through the center of the annular laser when the metal wire reaches the focus of the laser it forms a metal melt pool when the action of wire feeding is continuous it is matched with the bottom Then the molten pool will be cooled and solidified according to a certain trajectory and a certain shape of metal parts can be printed The schematic diagram is as follows Expand the full text This core technology is very important and advantageous
The laser ring can make the Titanium welding pipe laser focus fall on the central axis of the metal wire and the surface of the wire is irradiated by laser beams in 360 degrees which greatly improves the utilization rate of laser energy; The wire material and the laser are coaxial so that the metal molten pool can be formed and solidified along any direction that is printing can be carried out along any direction and the problem of directional defects caused by the traditional paraxial wire feeding is solved The advantages of laser coaxial fuse metal 3D printing technology in printing are mainly as follows 1 can print super-large parts suitable for industrial applications; 2 that quality and efficiency of prin metal parts are relatively high; 3 that prin material is a metal wire material so that the cost is greatly reduced; 4 It has higher environmental protection than powder metal ti6al4v printing technology; Therefore our technology and equipment are The first in China It not only fills the gap in the field of additive manufacturing in China It also improves the ability of printing large metal parts in China 04 Technology application 1 Print large metal parts large metal forgings and castings such as those used in aerospace and other fields with high technical content and accessory value 2 Repair of large shaft parts especially the remanufacturing and production process of large shaft parts in power generation equipment If our 3D printing technology is integrated with robots we can develop a laser coaxial fuse 3D printing robot which is equipped with the following equipment This equipment can not only print large parts 3d titanium wire but also be used in large shaft repair and other processes The application cases are as follows 3 If our 3D printing technology is integrated with the traditional five-axis CNC machine tool we can develop a five-axis composite CNC machine tool The five-axis material-adding and material-reducing composite machine tool not only has a good five-axis cutting function but also integrates the functions of five-axis metal wire 3D printing or five-axis metal powder 3D printing The technical equipment has a wide range of applications and can directly generate precision metal parts realizing the complementary advantages of material-adding and material-reducing processes The applicable cases are as follows 05 Research results Since 2014 the R & D team has been composed of engineers and technicians with rich R & D experience in mechanical electrical software process and materials With the support of major projects of the Science and Technology Commission the team has obtained 8 patents and 3 software copyrights and the ti6al4v eli achievements have been transformed into high-tech achievements in Shanghai
