Metal data additive manufacturing technology, also known as 3D printing technology and laser rapid molding technology, is mainly made of metal powder (metal particles with a size less than 1mm), particles or metallic films as raw materials. Through the CAD mold pre-division layer, high-power laser beam melting stacking growth (“additive manufacturing”) is used to directly complete the “near-final forming” of high-function components from a CAD mold step. It can be divided into laser direct melting manufacturing technology (Laser Melting Deposition, LMD) and selective laser melting technology (Select Laser Melting, SLM). Compared with traditional metal parts processing technology, metal data additive manufacturing technology has unparalleled advantages.
Added manufacturing technology has undergone three stages, including the technical incubation period from 1892 to 1988, the rapid prototype technology started in 1988, and the 20th century.
In 1979, UTRC proposed the concept of laser 3-body forming technology and produced return airborne engine wheel disc molding parts; since 1994, Rolls-Royce explored laser forming of aviation engine parts, and other members of the British Liverpool School and American Michigan School and Canadian National Research Committees. babyManufacturing Technology Research Institute, Swiss Polytechnic Institute, american Sandia National Laboratory, americanLos-Alamos National Laboratory, americanAeromet Company, american Binzhou Major, Birmingham Major, UK Birmingham Major, etc. have all started research and discussions. Because LMD has high powder feeding efficiency and good data density, it is increasingly used for additive manufacturing and part repair tasks for large parts.
Our foreign affairs were just while Ye Qiukong was still thinking, the program started recording again. The research and development of major parts additive manufacturing technology is mainly focused on amerSugar babyican. From 1995 to 2005, with the huge support of the American Ministry of Defense’s Advanced Research and Development Planning Office and the Naval Office, american John HapkinsMajor, Bentsyvania State and MTS have conducted a large number of research and development on laser rapid forming technology for aircraft olean alloy structures and have achieved serious progress. Based on this, MTS has established a dedicated research and development and engineering for laser rapid forming manufacturing technology for aircraft olean alloy structures in 1998. AeroMet, a company that uses manila, cooperates with Boeing, Lockheed Martin and Nosrop Gruman, three major military aircraft manufacturers in the american air force “Development Plan” (Air Force’s Forging Initiative), the Army’s Mantech Program, and the Ministry of Defense’s “Dual Use Scien<a With the help of other funds, we strive to discuss laser rapid forming technology for aircraft pine alloy structures and its key technology for application on aircraft. September 2000 at Boeing and Lockheed Pinay escort˙Mading Company completed the study of full-size aircraft wing bearing structures for laser direct forming kettle alloys. The structural static strength and fatigue strength meet the aircraft design request; in 2001, it manufactured a small batch of engine kettle alloy thrust pulling beams, engine wing turn-off joints, spars, ribbed wall panels and other aircraft kettle alloy secondary bearing structures for Boeing F/A-18E/F load joint tester in small batches. Among them, Sugar babyF/A-l8E/F Wing root crane ring meets 4 times the fatigue life expectancy, and the subsequent static force is not damaged. In 2002, laser rapid forming pine alloy secondary bearing structures were implemented on the F/Escort manilaA-18 verification machine. In addition, american will also be used for the manufacturing of F-22 connectors, and the testAs a result, he confessed that his life was exhausted and his life exceeded twice the life span.
When LMD technology was sure to be broken, foreign countries also used the technology to repair damaged parts, including repairing parts for aircraft parts, aviation engine grinding and other parts. americanAeroMet has completed the repair of the wingspar of the F15 fighter machine using laser forming technology; amSugar daddyericanOptomec Design has used laser forming technology to perform the wear repair of T700american naval aircraft parts; Swiss Institute of Technology Lausanne has used laser forming technology to repair single crystallized flies.
3D printing will become the mainstream production method for land and aviation fuel engine components
North Korea, the world’s aviation engines have cut short, and companies such as GE, PW, and RR have set their sights on this technology and have increased their research and investment in additive manufacturing.
GE company issued the portal number of “Print me the Sugar baby a Taiwanese spray engine” and conducted relevant research and development tasks. GE has applied LMD technology to conduct technical verification of related parts testing. In terms of refining data fan leaf metal reinforcement edge trial, first apply laser 3D to prepare metal reinforcement edge blanks Sugar daddy before applying laser 3D to the metal reinforcement edge blanks Sugar daddyCarry out mechanical processing. The entire reinforcement edge is about 101.6mm in length and has a wall thickness of 0.8~1.2mm. The final processing deformation is only 0.12mm. In addition, GE Escort also used additive manufacturing technology to realize the “printing” of the Leap-X developer center-type fuel nozzle. The application of 3D printing technology has extended to all business areas of GE, such as using calender alloys for the manufacturing of spray engines, and this technology is ultimately used for static replacement and dental implants. GE Oil & Gas has set up two new high-tech product component production lines in Talamona’s factory in Italy. One of the new nozzle production lines is the first complete Sugar babyPinay escort, a production line that is important to 3D-print the combustion chamber of the gas turbine. The two rebirth production lines have started operation and will begin comprehensive production in 2017. It’s like I’ve never talked about love, I won’t coax people, nor am I considerate.
The Ximen subsidiary will use 3D printing technology to manufacture metal parts of the combustion engine from January 2014. The entire process starts from a three-dimensional CAD number, and it will be fully and automatically processed through any machine to produce highly complex shapes. For some types of gas turbines, repairing damaged parts with 3D printers can save 90% of the repair time. In 2016, Ximen announced that it had invested 21.4 million euros in Sweden to build a 3D metal printing manufacturing factory in Sweden.Start mass production of industrial metal parts, including gas turbine parts.
