Time：2025-03-19
On March 17, TCTASIA2025 was held in Shanghai - National Convention and Exhibition Center, LiM Laser with 3 major metal additive “smart” manufacturing solutions shining debut, the first release of the LiM-X400 equipment equipped with laser heating solutions attracted attention, the program can break through the limitations of the traditional heating, relying on the 9000W The program can break through the traditional heating limitations, relying on 9000W high-power laser real-time heating, redefining the upper limit of metal additive manufacturing quality.
Laser real-time heating, breaking through the traditional heat conduction bottleneck
The traditional solution relies on the heat conduction of the substrate to heat the powder, and as the number of printed layers increases, the temperature of the powder bed gradually decreases, affecting the forming quality. LiM-X400 is equipped with a 9000W high-power multi-mode laser to heat the current layer of powder in real time, with a maximum heating temperature of up to 1,000℃; it relies on the real-time imaging and temperature measurement of the infrared camera, realizing the closed-loop precision control of temperature and power.
The program ensures that each layer of powder is in an advantageous molten state, significantly improving part density, especially for titanium alloys, refractory metals and other crack-prone materials stable molding.
High-end manufacturing fields such as aerospace require high precision and consistency of parts, and the laser heating function can effectively eliminate residual stress during the printing process, improve mechanical properties and inhibit cracks, which meets the user's stringent standards for critical parts.
Flexible Configurations, Double Jumps in Efficiency and Accuracy
LiM-X400 has two optional configurations of 400mm x 450mm x 550mm (W x D x H) dual laser and 450mm x 450mm x 550mm (W x D x H) quad laser, which can be flexibly configured with 500W or 1000W laser according to the demand, and is suitable for one-piece forming of parts in the fields of aviation and aerospace, energy and power, automobile manufacturing, mold manufacturing and so on. Molding.
Equipment forming cylinder is an independent unit module can be disassembled, the printing process and the powder to take the process of separation to achieve rapid cylinder change, continuous printing, greatly reducing the downtime waiting time; with the use of a number of forming cylinders, can be completed in parallel processing of multiple workstations, but also for the subsequent construction of intelligent production lines to provide strong conditions.
By optimizing the design of the wind field to effectively remove soot, keep the gas inside the chamber clean and the process stable, and further enhance the LiM-X400 printing consistency and uniformity; the use of imported THK screw guide, and equipped with a scale adjustment, can achieve the Z-axis positioning accuracy control within ± 0.005mm.
Intelligent production line, closed-loop control of the whole process
LiM-X400 meets the requirements of high quality and high efficiency production, and at the same time, it cooperates with cylinder management system, zero-point positioning system, automatic powder circulation system, monitoring system, truss transfer system, etc. to build up an intelligent production line with automated production capacity and sustainable operation, which further realizes the effect of large-volume and automated production.
Intelligent cylinder management system can realize automatic pick-up, cylinder specified movement, automatic cylinder installation and other operations, supplemented by high-precision and high-efficiency zero-point positioning system, realizing fast and reliable connection between forming shaft and forming piston, with repeatable positioning accuracy of ≤0.005mm.
Intelligent monitoring system with self-developed production line control and monitoring software can help users to master the working status and node operation of each equipment, and realize the whole process control of production process.
Combined with the intelligent truss transfer system, it realizes automatic cylinder identification and automatic transfer function according to the production process, improves the utilization rate of the production line, and ensures the consistency and high efficiency of the production process.
Transferring process: cylinder loading station - forming station - cylinder picking station - powder cleaning station - picking station -Powder cleaning station -Parts substrate storage area
Safety and certification for large-scale production
LiM-X400 strictly follows the safety standards, with perfect safety system certification, the whole machine has passed CE, explosion-proof, FDA certification, and at the same time complies with ISO9001, ISO14001, ISO45001 quality system, authoritative assessment, professional certification, to provide users with safe and reliable production guarantee.
The equipment adopts safety redundancy design, builds up a comprehensive safety protection system, equipped with forming chamber oxygen content monitoring system, carries out all-round oxygen content monitoring, ensures that the oxygen concentration in the chamber is maintained within 100ppm, and the exceeding of the limit is automatically alarmed, which ensures the safe operation of the whole machine system. Equipped with safety interlocking device, the door of the molding chamber can not be opened when the equipment is running; the laser can not be used when the door is opened, which doubly protects the safety of the operators.
With rich market experience and mature R&D system, LiM Laser continues to launch diversified and differentiated metal 3D printing solutions, continuously expanding application fields and application scenarios, and helping more industries to realize more efficient and higher quality automatic 3D printing.
