LiM Laser's Self-Developed Software System Empowers Intelligent Manufacturing in Aerospace
Author：
Time：2025-12-02
In the field of manufacturing large, complex metal parts, laser cladding equipment demonstrates unique value due to its advantages such as high powder utilization, intuitive and controllable processing, and continuous uninterrupted printing. Recently, the LiM-S6010 large-scale customized laser near-net-shape forming equipment was successfully delivered to a company in Hubei Province.
Our company tailored two core self-developed software programs for this equipment—LiMAMS-LENS laser near-net-shape forming pre-processing software and the LiM-S6010 laser near-net-shape forming monitoring and control system. These programs precisely solve the pain points and difficulties of traditional large-scale additive manufacturing equipment in terms of integration, operational efficiency, and printing stability, providing a solid guarantee for long-term, high-quality, continuous, and stable printing.
Slicing Software: Intelligent Process Planning Strategy for Reliable Quality
LiM Laser's self-developed intelligent slicing software achieves refined control throughout the entire process from model processing to printing output, laying a solid foundation for the successful printing of complex parts.
- Multiple Modes for Flexible Adaptation and Precise Response to Process Requirements
In the pre-processing stage, the self-developed next-generation slicing software demonstrates highly flexible customization capabilities. It supports slicing at any custom layer thickness and allows for different scanning paths to be planned automatically or manually within the same printing layer. The software offers various filling methods such as arc lines, parallel lines, spiral lines, and overlapping, allowing users to freely set the spacing, quantity, starting point, and direction of the filling lines and contours according to actual needs, precisely matching various printing scenarios from simple to extremely complex.
The self-developed software supports multiple filling methods for slicing within the same layer of the same print.
- Intelligent Partitioning and Sorting for Effective Printing Risk Control
Addressing the issue of uneven heat dissipation that easily occurs in the printing of large metal parts, the software integrates adaptive partitioning and intelligent sorting functions. Based on the geometry and hollow structure of the printed parts, the system automatically completes intelligent partitioning, ensuring that each partition is relatively independent, effectively reducing unnecessary printing interruptions.

This software, relying on advanced algorithms, optimizes the printing sequence of each partition according to process requirements, fundamentally avoiding deformation or cracking caused by localized heat accumulation due to continuous printing of adjacent partitions, significantly improving printing success rate.

- Parameter synchronization + multiple backup schemes strengthen quality control.
The post-processing stage of the slicing software achieves a dual upgrade in parameter control and scheme backup. Post-processing parameters set during slicing can be directly and synchronously output to the printing program, providing support for refined control during the printing process and ensuring precise and consistent process execution.
This software supports configuring a "one master, multiple backup" printing scheme for each printing layer—that is, each layer has one master printing program and three or more freely switchable backup schemes. Operators can quickly switch according to actual conditions, greatly enhancing the fault tolerance and continuity of the printing process, exploring a new safety assurance path for engineering applications.
Control Software: Real-time Monitoring of Processing Status, Stable Process
The control software, which iterates in tandem with the slicing software, forms the "intelligent hub" for stable equipment operation, enabling visualized and integrated management of the processing process.
- Real-time Information Synchronization and Full-Process Visual Monitoring
The control software can centrally monitor key data such as equipment status and process parameters on a single interface, and synchronize relevant information from the slicing software in real time. On the processing monitoring interface, the system synchronously displays the completed processing path, allowing operators to intuitively grasp the printing progress, quickly identify and intervene in potential problems, and significantly improve operational efficiency and process controllability.
Printing a Ring Test Part Based on Self-Developed Software
The independently developed industrial-grade adaptation software is a crucial component of LiM Laser's end-to-end metal 3D printing solution. The intelligent slicing software and control system tailored for the LiM-S6010 equipment not only significantly improves equipment efficiency and process standardization but also demonstrates the company's comprehensive strength in software development.
In the future, LiM Laser will continue to delve into various types of metal 3D printing technologies, further improve its independent software ecosystem, and provide more intelligent and stable digital solutions to help upgrade the manufacturing capabilities of the commercial aerospace sector and contribute innovative power to "Made in China 2025".
