Time：2025-03-24
TCT ASIA 2025 came to an end, LiM Laser made a stunning appearance with three major metal additive “smart” manufacturing solutions and new application cases, hot field application exhibits.
Round to Square
LiM-X1500H equipment manufactured aero-engine parts round to square debut, aluminum alloy (AlSi10Mg) size of 1290mm × 1180mm × 506mm, the part contains a large number of hollow structure and reinforcing bar structure, the use of traditional technology processing difficulties, low production efficiency; through the integration of SLM technology, greatly simplify the production process, shorten the production cycle, forming efficiency increased by 50%. Through SLM technology, the production process is greatly simplified, the production cycle is shortened, and the forming efficiency is increased by more than 50%; the machining cutting volume is effectively reduced, the material utilization is improved, and the production cost is lowered.
At the end of 2024, LiM Laser released LiM-X800H+ equipment with a net forming height of 2.5m, and this time we are exhibiting its latest application cases for aerospace parts.
Spiral Structural Part
Spiral Structural Part
The part is a titanium alloy (TA15) spiral structural part with the size of 418mm×362mm×2210mm. The multi-laser synergistic technology guarantees the forming quality of the part and reflects the process stability of the equipment; it also provides feasibility verification for the rapid manufacturing of ultra-size and lightweight parts in the fields of aerospace and large-size molds and dies.
Aircraft frame
The first exposure of the super 6-meter large titanium alloy (TA15) aircraft frame, the exhibit size of 6295mm × 2198mm × 614mm, with a one-piece lightweight body skeleton structure as the application background, to carry out additive manufacturing process based on the development of large-size overall reinforcing structure and process research, and to provide data support and process guidance. The hybrid manufacturing process of coaxial powder feeding and traditional machining is used for molding, combined with special connection technology, new stress relief technology and other means, which has outstanding results in improving manufacturing precision, increasing product size and improving production efficiency.
Heat exchanger
Aluminum alloy (AlSi0Mg) heat exchanger with dimensions of 569mm×527mm×512mm, topology optimization strengthens the main structure while optimizing the weight, and large-size one-piece molding demonstrates process stability.
Low-altitude economy and artificial intelligence as an emerging industry has attracted much attention, and additive thinking to lead the design and manufacture of related parts also provides a proven solution for the industry to break through technical bottlenecks, reduce costs and increase efficiency, and further expand the market space.
Drone Frame
At this year's TCT, LiM Laser exhibited a titanium alloy UAV frame printed by LiM-X260A equipment, with a size of 153mm×153mm×25mm and a weight of only 0.3kg. The technical team adopted a topology-optimized structural design scheme to reduce the number of parts and components, shorten the manufacturing process and production cycle, and the printing can be completed in 5h; at the same time, it effectively guarantees the mechanical properties, reduces quality risks, and significantly improves the mechanical performance of small-sized UAVs. At the same time, it effectively guarantees the mechanical properties, reduces the quality risk, and significantly improves the overall reliability of small and complex parts.
In addition, there is the use of LiM-X400 equipment to print the aluminum alloy (AlSi10Mg) robot leg bone, size 200mm × 170mm × 400mm, only 48h printing completed. High-strength aluminum has low density and high strength, and there are problems such as low densification and high tendency of cracking when using SLM forming, but the exhibit has good surface quality and excellent mechanical properties, which guarantees the robot's stable gait and natural appearance, fully demonstrating LiM Laser's mature process of forming high-strength aluminum materials.
Waterway mold
LiM-X400M+ printed waterway mold, with the size of 343mm×242mm×120mm, took 120h to print and complete, the mold is used in the manufacture of automotive parts, and the use of SLM molding shortens the processing time of the mold, reduces the difficulty of the processing, and makes the production and processing process more green and environmentally friendly.
Whole plate watch
Frame whole plate hinge
LiM-X260A printed whole plate watch frame and hinge, showing the mass production capacity of metal 3D printing technology in 3C parts manufacturing scenarios.
Pure copper and copper alloys have good thermal and electrical conductivity, corrosion resistance, and are widely used in the industry. LiM Laser displayed numerous application cases that demonstrated good molding processes.
cooling disk
LiM-X400 printed chromium-zirconium copper (CuNi2SiCr) heat dissipation disk with a size of 340mm×340mm×18mm, flexibly designed based on additive thinking, with rich flow paths, complex structure, and high processing difficulty; the use of SLM one-piece molding enhances the overall structural performance of the part, with excellent internal quality and more uniform heat dissipation effect, which can fully meet the requirements of product application.
For pure copper and other highly antimetallic materials, LiM Laser launches green laser additive manufacturing solutions based on its self-developed LiM-X series SLM equipment, realizing high-quality pure copper printing.
Thrust chamber
Heat dissipation fin structure
TCT exhibited the pure copper (T2) thrust chamber and heat dissipation fin structure printed by LiM-X260E green laser equipment, showing the mature molding process for highly anti-metal materials.
Musical Instrument Parts (Cylinder)
In addition, LiM Laser exhibited musical instrument parts cylinders made of brass (H85), expanding the application of SLM technology to the field of precision musical instrument manufacturing for the first time. Copper has high anti-sublimation characteristics and zinc has low melting point, so copper-zinc alloy is easy to sublimate and difficult to form during the printing process. Using LiM-X260A equipment to form the cylinder, the final product has good surface quality and excellent mechanical properties, which reflects our exquisite process technology level.
TCT ASIA 2025LiM Laser is a perfect ending, we will continue to focus on metal 3D printing technology, uphold the concept of “make manufacturing more efficient”, and lead the manufacturing industry to gradually move towards a broader future.
