At the beginning of last year, the additive technology of multi-laser coaxial thread developed independently by Rongsu technology was officially unveiled and was successfully applied to mass production equipment. Currently, manufacturing equipment for laser wire supply additive equipped with this technology has been shipped by lots one after the other. Recently, based on VEAM technology, Rongsu technology and the Laser Aérospatial Science and Technology Institute jointly innovated and jointly announced the successful development of the additive technology of high-power multi-laser coaxial wire (veam-blue laser) “and has developed a high-power blue-ray-ray radiography laser, the technology of the addition of domestic laser and laser Metal las forums Make revolutionary progress in the additive manufacturing of copper components.
Domestic metal wire copper parts are always empty
Due to its excellent thermal conductivity, its electrical conductivity and its ductility, metallic copper and its alloys are widely used in electrical manufacturing, mechanical manufacturing, aerospace and other fields, and are the third largest industrial metal in the world. However, the high copper reflectivity properties posed it in huge challenges in traditional 3D laser printing.The rate of absorption of copper to infrared lasers with wavelengths from 900 to 1100 Nm is extremely low, only about 5%, which leads to 95% of reflected laser energy and the rate of energy use is low. It is subject to defects such as pores and cracks and cracks during the printing process, which seriously limits the development of the additive manufacturing of copper components.
Although the additive DED wire feeding technology has a high deposit rate and large -scale printing capacities, interior technology is still in a virgin state in the field of high metallic printing, in particular in the manufacture of large copper components, and revolutionary solutions are necessary urgently.
Technical breakthrough: Light Blue Light Multi -Laser Coaxial Wire Feeding Additive Technology Veam – Blue Laser
Against this background, Rongsu Technology and the Aerospace Science and Technology Laser Institute Jointly Developed The “Blue Light Multi-Laser Coaxial Wire Feeding Addive Addive Technology (Veam-Blue Laser), Which Successfully Solved the Aboved Problems. Additif Technology Independently Developed by Rongsu Technology, Combined With the Deep Accumulation of the Aerospace Science and Technology Laser Institute in the Field of Optoelectronic Systems Engineering, it innovatively introduced blue light and combined Lasers with the Six Laser Coaxial Wire Technology Copper and other highly reflective metals.
Three major technical strengths, making a huge jump in additives such as copper and other highly reflective metals
1. The absorption rate of the light blue laser is high, perceiving the bottleneck of high reflection metal printing
The wavelength of the blue light laser is 400 to 500 nm, and the copper absorption rate at the wavelength of 450 Nm exceeds 60%, which is more than 10 times that of the infrared laser. This characteristic considerably improves the effectiveness of energy use and improves printing quality. At the same time, the blue laser is also suitable for printing other highly reflective metals such as aluminum (al), gold (au), silver (AG).

2. High machining precision and excellent parts performance
The blue laser has a small place and a high energy density, which makes it suitable for the printing of fine structures or complex parts. At the same time, the energy of blue light is concentrated in the treatment area and the heat -affected area is smaller, reducing the beach in receipt of the heat of the material, helping to reduce microfissurs and pores and improving the mechanical properties of printed parts.
3. Deep integration of laser and blue boarding technology
This cooperation has innovatively adopted six blue -ray blue ray lasers with high controlled high power, which have not only fully used the advantages of the high absorption rate of blue laser, high treatment of treatment and a high energy conversion rate, but also combined with high forming accuracy, uniform energy distribution and stable energy distribution, driving rate of material Rongs. This merger has made a significant jump in the application of blue light lasers in the field of copper manufacturing.
The future application scenarios are wide and ensure new momentum for high -end manufacturing
Blue Light Multi-laser Cooxial Wire Feeding Additive Technology combines the advantages of blue laser and Veam technology. It guarantees not only the overall performance and reliability of copper parts, but also improves the mechanical properties of parts, such as resistance, hardness and tenacity. This technology can be widely used in the manufacture of high-performance copper components such as rocket engine parts, high-efficiency heat exchangers, micro-reed plates, etc., to meet the needs of high performance, light and complex copper components.
The chief scientist WU Chunfeng said: “As a representative of cooperation and innovation of central and private companies in the fields of science and technology, the Core Aerospace Science and Technology Based on the main national strategic needs. The integration of the laser network has filled the gap in the laser engineering application with a domestic blue network and has injected new momentum into the innovation independent of high -end equipment. “”
The successful research and development of the Veam-Blue laser percene not only the technical bottleneck for the manufacture of copper additives, but also provides a new solution for the printing of other highly reflective metals. In the next step, Rongsu technology will continue to engage in the research and development of the multi-laser additive technology of blue light, continuously promoting the process of industrialization of VEAM blue laser technology, providing the market for more efficient and more efficient copper laser solutions.
