When giant aerospace components require millimeter-level precision in a single pass, and when complex components for energy equipment urgently require more efficient manufacturing solutions, the LiM-X1500H ultra-meter-class metal 3D printing system, with its ultra-large build volume of 1500mm × 1500mm × 1650mm (including a 150mm standard substrate thickness), offers a groundbreaking solution for high-end manufacturing. It meets the aerospace industry's needs for lightweight and customized production of large, oversized, and complex structural components, as well as small-batch, rapid manufacturing of small and medium-sized parts.
Equipped with 16 lasers, the system achieves a maximum build rate of 1000 cm³/h; equipped with 24 lasers, it reaches a maximum build rate of 1500 cm³/h.
Core Technology Leads Efficient Precision Manufacturing
To ensure efficient and stable operation, the LiM-X1500H incorporates targeted design and innovation in multiple key technologies.
- Single-blade, bidirectional powder spreading solution: Compared to dual-blade designs, a single blade is quicker and easier to set up; a bidirectional intelligent variable-speed powder spreading strategy ensures efficient and high-quality powder spreading.
- Innovative air field design: A double-layer air field structure effectively removes dust even at extremely large spans, significantly improving the uniformity and stability of ultra-large-format multi-laser printing.
- Intelligent, stable and reliable monitoring: The build chamber has a built-in oxygen content monitoring system that automatically alarms when the oxygen content exceeds the limit, ensuring production safety. A powder bed monitoring system automatically replenishes powder and provides an alarm for abnormal powder spreading.
- Proprietary software system: Equipped with LiM-BP intelligent software, it supports efficient, one-time segmentation of large parts, accelerating large-scale additive manufacturing.
In addition, the LiM-X1500H supports multi-laser zoning optimization strategies, precisely balancing print quality and efficiency. It can be integrated with a fully automatic powder circulation system for automated powder flow.
Typical Applications Demonstrate Stable Forming Processes
Based on years of equipment R&D experience and tens of thousands of print tests, the LiM-X1500H demonstrates stable and reliable printing performance for high-end manufacturing requirements such as complex aircraft engine components, large load-bearing structures for space launch vehicles, and core components for energy equipment. It efficiently completes the integrated manufacturing process from design drawings to actual parts.
A key engine part printed by the LiM-X1500H contains numerous hollow structures and reinforcing ribs, making traditional manufacturing difficult and inefficient. 3D printing significantly streamlines the production process, shortens processing cycles, and increases forming efficiency by over 50%. It also significantly reduces machining cutting, improves material utilization, and reduces overall costs.
Building on the outstanding performance of the LiM-X1500H, LiM Laser has innovatively developed the LiM-X1500HF "on-the-fly printing" machine. This machine manufactures blade rings, key components for aerospace engines, with a diameter exceeding 1400mm. The blades are a composite impeller structure with numerous thin blades. The printed product features a dense, defect-free surface, weld-free joints, and uniform overall appearance. Ribs are evenly distributed across the exterior surface of the part to enhance overall strength and rigidity. The use of high-temperature alloys further ensures stable performance in high-temperature, high-pressure, and high-velocity airflow environments.
Amid the accelerating upgrades of strategic emerging industries such as aerospace and energy power, the LiM-X1500H has won numerous innovation awards for its core strength of "large and precise." This recognition is a testament to its exceptionally large 1500mm × 1500mm × 1650mm build envelope and precision manufacturing capabilities, and a testament to LiM Laser's commitment to core additive manufacturing technologies.
