　　In 2023, LiM Laser launched LiM-X400M after many optimization and program verification to meet the needs of mass production of consumer goods industry users and small batch trial production of complex structural parts and miniaturized precision parts, the stability of the equipment, production efficiency, print quality and so on have been fully verified and highly recognized.

　　At the end of 2024, on the basis of stable and efficient production of the equipment, we also launched LiM-X400M+ equipment based on feedback from users, upgrading the forming size to 400mm×300mm×450mm (W×D×H), further expanding the forming space, bringing economic, efficient and more cost-effective solutions to meet the needs of batch production of electronics, mold making, automotive manufacturing, education, medical care, culture and creativity, and meeting the needs of batch production. It brings economical, efficient and more cost-effective solutions for users in 3C electronics, automobile manufacturing, education, medical care, cultural and creative industries, and meets the needs of batch and diverse production.

　　Excellent performance: three lasers work together efficiently

　　LiM-X400M+ is equipped with 3×500W lasers, and the maximum molding efficiency can reach 75㎥/h, which meets the users' high demand for productivity while taking into account the cost of the equipment.

　　The equipment adopts the design of single squeegee single/bidirectional variable speed powder spreading, which effectively shortens the time of squeegee installation and leveling on the one hand; on the other hand, it can give full play to the ultimate efficiency of each laser, reduce the waiting time for light output, and improve the printing efficiency.

　　Feature-rich: supporting large-scale production

　　LiM-X400M+ equipment is independently controllable in terms of technology and functions, providing strong support for industrialized application.

　　Multiple Scanning Strategy Slicing: Adopt multiple scanning strategy slicing for a single part, so that the part can obtain various physical properties in the microscope, enhance the performance dimension, and then improve the printing quality.

　　Variable Layer Thickness Printing: Supports multiple layer thickness parts to be printed at one time, such as printing a certain part, 0.04mm layer thickness can be flexibly adjusted to 0.02mm, 0.03mm layer thickness; in addition, it can also realize the simultaneous printing of parts with different layer thicknesses, saving downtime and improving production efficiency.

　　Substrate temperature control: Substrate temperature can be set for different printing heights and different printing stages to ensure smooth printing and effectively improve the stress and deformation caused by the structural characteristics of the product to ensure molding quality.

　　Distinguish internal and external contours: In the face of parts with internal runners, the internal and external contours can be treated differently. Scanning the internal contour ensures the smooth surface of the part's waterway; not scanning the external contour saves the scanning time of the processed surface, and reduces the consumption of extraneous details on the production capacity.

　　Reliable Quality: Multi-module Intelligent Inspection

　　Users can choose a number of intelligent inspection modules to ensure the molding quality, including powder bed monitoring module, melt pool monitoring system and production quality management system, etc., to provide a strong guarantee for the whole process of quality control and process traceability.

　　Powder bed monitoring module: Built-in high-definition camera takes images of powder bed status after each powder spreading and melting, analyzes and compares them by algorithms, derives the information of powder spreading status and printing area and gives feedback in real time, and carries out automatic powder replenishment and automatic alarm for abnormal powder spreading.

　　Melting pool monitoring system: It is mainly used for real-time monitoring, analyzing and evaluating equipment melting pool information. On the one hand, it can detect whether the melt pool is unstable in real time, and on the other hand, it can be used as a quantitative pointer for the optimization of the process strategy, and through the analysis of the mapping relationship between the process parameters - the melt pool state - the signal characteristics, it can realize the assessment of the process state, so as to ensure the quality and consistency of the parts. In addition, real-time monitoring is the basis for closed-loop control as well as intelligence of the metal 3D printing process.

　　Production Quality Management System: Predictive maintenance is provided for the most common overflow bucket full alarms during the printing process. Users can predict the time to clean up the overflow bucket by using the powder volume curve to avoid the resulting unplanned downtime. Sensor data and log files during printing are recorded on a job-by-job basis to support production quality management.

　　In addition, LiM-X400M+ is also equipped with automatic grafting technology, which can realize the effective fusion of different parts and different metal materials, and complete grafting printing efficiently, stably and accurately.

　　LiM Laser always adheres to the principle of “application-oriented and market-oriented”, and focuses on the requirements of various fields, explores rich application scenarios, and lays out the future industry in a forward-looking manner, so as to provide high-quality and high-efficiency metal 3D printing solutions for more users, and help them transform and upgrade their business.
