Metal 3D printing -- digital green intelligent manufacturing technology

In recent years, the state has made great efforts to develop a circular economy and promote the economical and intensive use of resources. In July 2021, the National Development and Reform Commission issued the 14th Five-year Plan for Circular Economy Development, which laid out five key projects, including the construction of a recycling system for waste materials in cities, and six key actions, including the high-quality development of the remanufacturing industry. Carrying out scientific research and engineering application of remanufacturing is of great significance to ensuring national resource security, helping to achieve carbon peak and carbon neutrality, and promoting ecological civilization construction. At present, remanufacturing has been widely used in steel, nuclear power, coal mine, automobile, aviation, mold and other fields.

Let waste products through digital technology means to repair and transform, restore the original value, this is the remanufacturing process. The remanufacturing process, generally can be over 60% of energy, managing material by more than 70%, save costs by more than 50%, and some of the remanufacturing product can even more than the performance of the prototype product, not only has a good economy, is also more convenient and efficient, especially for the early stage of the import or discontinued products, remanufacturing is basically the only solution, Metal 3D printing remanufacturing is one of the most advanced technologies.

China Baowu - Smart Steel promotes the industrialization of 3D printing

China Baowu Iron and Steel Group Co., LTD. (hereinafter referred to as China Baowu) is a joint restructuring of the former Baosteel Group Co., LTD and Wuhan Iron and Steel (Group) Co., LTD. Baowu Group is carrying the historic task of transformation and upgrading of China's steel industry, and smart steel is an important starting point to promote the supply-side structural reform of the steel industry. As early as 2006, Baosteel applied 3D printing to the steel industry, using projects to promote the further development of 3D printing in the industrial field. In recent years, we have successfully "printed and remanufactured" a series of products such as rolling mill memorial arch, flat head cover, universal joint shaft and foot roller, and have participated in the development of a number of industrial standards for laser additive remanufacturing.

Giving old parts a new Life

 

Metal parts can be printed directly by connecting them to laser 3D printing equipment, which not only gives old parts a new lease of life, but also improves performance and longevity. This is not a science fiction movie, but a technological revolution in manufacturing happening all around us.

In 2020, BAOsteel Academia Sinica purchased a Laser near-net forming equipment LIM-S0402 from Tianjin LiM Laser Technology Co., LTD. (LiM Laser for short). Dr. Qiong Wu from ACADEMIA Sinica said: "At that time, I was planning a research project, aiming at the loss of functions of some key equipment in the factory due to wear and cracking in the process of use, I was thinking about how to restore the original functions and reduce losses by means of repairing them. In order to solve this problem, a series of research and comparison of surfacing, spraying, plasma repair and other technologies were conducted to select a Laser 3D printing solution. LiM Laser's near-net forming equipment LIM-S0402 was purchased through tender."

Dr Wu said: "First of all, laser 3D printing is more controllable in terms of energy and shape. Secondly, laser 3D printing can choose a wide range of materials; Third, the operation and maintenance of laser 3D printing equipment is also more convenient. Laser 3D printing has a large demand in steel application scenarios, and a lot of research and development work will need to rely on this technology in the future. In the laboratory, we mostly use it for design and simulation experiments. First, it is used to explore materials and study what materials are used to repair or strengthen. Second, it is used to explore technology and accumulate reference technology for large-scale production of physical repair. So far we have developed solutions to multiple field problems using the equipment and applied them to large production."

High efficiency & low cost

3D printing is making a big splash in the steel industry

 

In the process of parts repair, the manufacturing cost of re-opening mold is high, and there is no need for mass production, so 3D printing provides a new idea for product repair. First through surveying and mapping, the establishment of the components of the three-dimensional model diagram, and then through the slice, design good print path, and stored as 3 d printers can directly read and use the file, will load the file to the printer, at the same time into the 3 d printing materials, debug print platform, set the print parameters, the finished parts of material processing.

Advanced metal 3D printing additive manufacturing equipment can be used to select the most appropriate processing technology according to the working conditions, material characteristics and production technical requirements of the processed workpiece, improve the wear resistance, corrosion resistance, oxidation resistance and thermal corrosion properties of the metal surface, repair the service damage and manufacturing defects of the metal surface. Realize the reliable connection of metal components that are difficult to fuse, weld and easy to deform.

Professionalism & Sincerity

Win the trust of customers

 

LiM Laser has more than 200 employees, including more than 50 technology r&d team members, mainly from internationally renowned additive manufacturing equipment companies and a number of key universities in related fields. More than 50% of the team members have more than 10 years of product development and lean manufacturing management experience. The company has more than 70 core technology patents, and has obtained a variety of honors and qualifications such as national high-tech.

According to Dr. Wu, "LiM Laser attached great importance to our project. In the early stage of communication, the project leader communicated with us several times, exchanging many opinions on the civilian metallurgical industry market and 3D printing remanufacturing technology, from hardware installation and debugging to software operation demonstration. LiM Laser gave us professional and patient guidance. Through this process, our team was impressed by LiM Laser's sincere service attitude and established a good foundation for cooperation."

 

      

Compared with the traditional manufacturing mode, 3 d printing is not the restriction of the traditional technology and manufacturing resources, greatly reduce the development cost, shorten the development cycle, also break through the limitation of the traditional manufacturing technology for complex shape, it brings about a revolutionary change, is a production and processing of the driven equipment remanufacturing field played an important role. In the future, LiM Laser is committed to expanding the extension of Laser 3D printing remanufacturing technology and promoting the wider application of 3D printing in the industrial sector.
