LiM Laser's Fine Structure Printing Solution Leads a New Revolution

Time：2025-09-04
In recent years, metal 3D printing technology has continued to advance and improve, with applications spanning large manufacturing sectors like aerospace, as well as civilian markets like consumer electronics and intelligent robotics. Demand for printing fine components continues to rise across various industries, with increasingly stringent requirements for product precision, surface finish, and consistency. Based on the stable and efficient production of its equipment, LiM Laser has undergone multiple process optimizations to launch its fine structure printing solution. This significantly raises the upper limit of metal 3D printing quality for processing small, complex components, providing users with an additive manufacturing solution that combines technological advancement with engineering practicality.
Fine Structure Printing Solution
Components in industries such as consumer electronics, intelligent robotics, and low-altitude flight are characterized by small size, fine structure, and high quality requirements. They often contain lattice, porous, lattice structures, or complex internal flow channels. Traditional manufacturing processes are challenging, and polishing and other methods to improve surface quality are difficult.
LiM Laser, based on its proprietary LiM-X series SLM equipment, has developed a fine structure printing solution that can directly form complex precision components. The finished product achieves a surface roughness of ≤ Ra 3.2μm and a printing accuracy within ±0.05mm. The resulting surface quality is clear, the structure is intact, and the surface quality is excellent. This not only avoids dimensional errors caused by post-processing but also significantly shortens the manufacturing cycle.
Red Laser Fine Structure Forming
Superalloys offer high high-temperature strength, excellent oxidation and corrosion resistance, and fatigue properties, along with excellent structural stability and operational reliability across a wide range of temperatures. Therefore, they are commonly used in aerospace engines, energy, and chemical industries.
LiM Laser utilizes the LiM-X150A equipment and fine structure printing process to produce exhibits with high surface finish and intricate structures.
The model features crisp textures and a complete structure. The Roman columns have distinct layers, the window panes are clearly visible, and the eaves have a rod diameter of just 0.2mm.
Other exhibits include dragon-patterned staffs and Terracotta Warrior figurines. The dragon-patterned staff features a lifelike dragon carving, with clearly visible scales and delicate and elegant cloud patterns. The overall design is rich in detail and exquisitely compact. The Terracotta Warriors are intricately detailed yet clearly visible, their demeanor and armor vividly rendered, creating a vibrant and majestic image.
The high-temperature alloy specimen formed using this solution achieved a surface roughness of only Ra 2.3μm.
Green Laser Fine Structure Forming
Pure copper and copper alloys have excellent thermal and electrical conductivity and corrosion resistance, making them widely used in industries such as aerospace, machinery manufacturing, shipbuilding, automotive, and consumer electronics. Applications include heat exchangers, coolers, water-cooling molds, electronic components, engine parts, and pipe fittings.
LiM Laser used a LiM-X260E green laser system to print a pure copper relief badge. The badge features a square porous structure with an internal pore diameter of ≤240μm, a rod diameter of ≤230μm, and a highly precise layer thickness of ≤20μm.
The uniform pore distribution allows for light transmission, maintaining structural strength while creating a unique play of light and shadow.
The printed pure copper grille specimen has an internal wall thickness of ≤0.13mm; the pure copper sheet specimen has a sheet thickness of only 0.2mm and a gap of only 0.15mm. Both fully demonstrate our company's exquisite craftsmanship in printing fine structures in highly reflective materials such as pure copper.
Currently, various industries are continuously demanding higher performance and refinement of precision components. LiM Laser's new printing process will provide users with more efficient, stable, and high-quality solutions. Going forward, we will continue to deepen our technological research and development, driving manufacturing innovation and supporting industry upgrades through continuous equipment iteration and process optimization.
