Recently, LiM Laser SLM additive manufacturing device LiM-X650H was awarded the 2022 Metal Working Industry -- Jung Technology Innovation Award. The device, which has been introduced since 2021, is another honor after winning second place in the "Top 10 Industrial-Grade Additive Manufacturing Equipment of 2021" competition in January 2022.

LiM laser large-format, high-size LiM-X650H equipment forming size of 650mm×650mm×1680mm (including substrate), and optional 4, 6 laser, especially in the printing depth, has reached the international leading level, and has one of the highest level of commercial sales of metal additive manufacturing equipment.

The equipment structure adopts the patented LiM-X400H dual-drive structure successfully developed by LiM laser, which realizes the gantry dual-drive structure while greatly reducing the overall height of the equipment. In the existing laser selective melting equipment at home and abroad, the equipment with forming format more than 500mmx500mm are using single drive structure. According to the mechanical structure analysis and stability calculation, it is difficult to achieve the positioning accuracy of the forming cylinder within ±5μm by single drive. Dual drive structure adopts Siemens stable and mature control system, with double grating ruler, so that the positioning accuracy of the equipment can be stable within ±5μm for a long time, to provide customers with a stable and reliable drive control.

Full automatic powder conveying system

Large size parts printing cycle is long, the amount of powder is large, long cycle printing environment stability control is very important. The equipment with complete closed-loop automatic powder conveying system, add powder, the device can automatically screening and baking powder to use state, printing process, the system efficiently and automatically sieving powder recovery, excess powder, powder supply three processes, work independently, without affecting the forming tank print, which lose powder efficiency more than 10 l/Min. The whole process without manual intervention, to ensure the yield, efficient, practical and safe.

Safety guarantee, stable and reliable

Mechanical property test

The minimum mechanical properties of the multi-laser lapping region are not less than 95% of the average value of the single laser region. The consistency difference of mechanical properties of the whole format is less than 5%; Nickel base superalloy, high strength aluminum alloy, titanium alloy, stainless steel and other materials, the standard sample bar at room temperature tensile performance test is excellent.

Multi-laser printing stitching area verification

LiM-X650H equipment can be applied in the integrated molding of complex structural parts in many fields such as aviation, aerospace, energy and power, automobile manufacturing, etc. At present, there are mature printing parameter packages of titanium alloy, superalloy, aluminum alloy and other materials. The equipment has excellent performance in forming efficiency, printing quality, use cost and other aspects. Many batches of complex structural components such as rotating knock assembly and isolation section have been printed and verified.
