With the improvement of the performance and structural complexity of metal parts, the difficulty, cost and cycle of manufacturing by traditional processes such as casting and forging are increasing rapidly. Laser additive manufacturing technology with advanced technology and resource economy provides a new solution.
Laser additive manufacturing metal parts technology hasMeet the complex structure, near net shape high precision, excellent performance and other characteristicsIt can change the processing mode of traditional metal parts. It is one of the most promising application technologies for manufacturing complex precision metal parts, and it is also one of the key basic technologies supporting intelligent manufacturing in aviation, aerospace, medical and other fields.
Based on the long-term observation of the market andMetal Additive ManufacturingRecently, the research and development team of radium laser process successfully printed out the laser power, spot size, scanning strategy, scanning speed and other process parameters LiM-X260A by adjusting the laser power, spot size, scanning strategy and scanning speed of the self-research equipment.Aluminum alloy large area (150mm * 150mm) limit size structural parts, The overall structure of the formed parts is intact, and the thickness is uniform,The rod diameter is 0.2mm, and the rod diameter dimension accuracy reaches ± 0.025mm.
cell structure model
The part has the characteristics of small rod diameter, low strength and fragility. The cross cell structure determines the growth direction of 45 degrees, resulting in easy ball formation at the dot matrix node, which is extremely difficult to form. The previous process can only meet the forming conditions of the minimum rod diameter of 0.4mm. Radium laser process personnelBy optimizing the forming process and breaking through technical difficulties, we have successfully LiM-X260A our self-developed equipment.On the realization of stable productionThe customer is highly satisfied with the finished part.
Partial Rod Diameter at 50 Magnification
This marks the greater possibility of deep integration of radium laser equipment and research institute research and development, and radium laser equipment and technology have once again entered a new height.
LiM-X260 SeriesIt is a customizable laser selection melting equipment introduced by Radium Laser after many product iterations and validations,Forming size is 260mm✖260mm✖430mm, the maximum forming efficiency of single laser is 30cm ³/h; The maximum forming efficiency of double lasers is 45 cm³/h.
The use of independent research and development of LiMPCS equipment control software, through industrial computer control, to achieve the automation of equipment printing, the use of special motion control system and imported servo drive, great.Improve the accuracy and stability of the movement of the forming system and the powder laying system.Can carry out a variety of alloy materials printing research, such as titanium alloy, aluminum alloy, high temperature alloy, cobalt chromium alloy, copper alloy, etc.
Radium Laser will continue to practice and optimize, continuously explore the limit size forming process scheme and process parameters, and realize the printing of limit size structural parts of different materials such as titanium alloy and superalloy on large equipment such as LiM-X400 series, LiM-X600 series and LiM-X800 series, so as to provide customers with the best part process scheme, continuously give full play to the advantages of metal additive manufacturing technology, provide more possibilities for manufacturing and create "limit possibilities".
Metal Additive Manufacturing
Permalloy refers to an iron-nickel alloy with a nickel content in the range of 30% to 90%. This kind of soft magnetic alloy can effectively control the magnetic properties through appropriate process. It is a typical functional material with high permeability, low coercivity, high saturation magnetic induction, high Curie temperature, good corrosion resistance and good processing performance. Mainly used in alternating magnetic field, widely used in aerospace industry and telecommunications, measurement and control system. Commonly used permalloy 1J50, 1J79, 1J85 and so on. In the field of aerospace industry, permalloy is mainly used to manufacture precision components with high sensitivity, fine size, small size and low high frequency loss.
Additive manufacturing combines 3D printing with industrial production, creating a new processing method, and has irreplaceable advantages in the manufacturing of complex structural parts. Recently, Dr. Guan Kai, general manager of Tianjin Radium Laser Technology Co., Ltd., accepted an exclusive interview with MM's "Insight" program and expressed a clear view on the hot topic of additive manufacturing. MM "Insight"
The 6th China (Xi 'an) International 3D Printing Conference and Qin Chuangyuan 3D Printing High-end Forum opened today. Radium Laser was unveiled with LiM-X150A equipment and typical metal 3D printing displays, sharing technological achievements and application cases, discussing the future development direction of additive manufacturing, and going to the digital future together.
