In the aerospace and aviation field, the application of metal additive manufacturing technology has been very extensive. However, due to the complex design of the internal structure of the parts and the high precision requirements, the use of traditional manufacturing methods requires higher costs and longer time, and the production efficiency and cost control of enterprises are facing significant challenges. In the face of such a difficult situation, BLT has set up an independent R&D team from the development stage of the first machine, focusing on the development of intelligent software and hardware systems designed specifically for metal additive manufacturing.
After more than ten years of research and development experience, BLT has created a complete process monitoring system, including BLT-Intelligent Recoating Detection, BLT-3D Reconstruction and BLT-Video Monitoring module. The system includes the whole process monitoring from the beginning of manufacturing to the completion of pickup, which can realize visualized easy operation and intelligent real-time, help efficient and intelligent quality management of the production process, and save nearly 500,000 invisible costs for customers every year.
BLT-Intelligent Recoating Detection
BLT-Intelligent Recoating Detection can intelligently recognize the complex environment of different models of equipment in the process of printing and spreading powder, with the advantages of high detection accuracy, high finished product rate, and reduced labor costs. The software can intelligently recognize abnormal conditions such as lack of powder, squeegee jamming, and powder spreading cuts. The identification process does not need to worry about the impact of the printing environment, the detection success rate of up to 98%. The whole inspection process supports printing without stopping, and realizes the self-treatment of powder laying problems, which greatly reduces the time and labor costs.
BLT-3D Reconstruction
BLT-3D Reconstruction uses a high-quality industrial camera to take pictures of the forming section layer by layer, realizing real-time tracking of the forming process and accurately locating model defects during the printing process. It can clearly and accurately efficiently locate the defective areas of model slices, which is easier to trace when optimizing at a later stage; this module can not only track the formed section in real time, but also simulate the section about to be printed, which makes it easy to correct possible future errors in a timely manner, and improves the stability of the overall printing process. It takes only 3s to rebuild 12,000 layers with this function, which is in line with the demand for efficient, multi-layer reconstruction of large-size parts in the aerospace and aviation industry.
BLT-Video Monitoring
BLT-Video Monitoring plays a role in tracing the quality of the printing process, and equipped with a very clear operating screen, support for local one-key access. It supports video recording of the entire 3D printing process, and you can choose to assemble more than 4T capacity of large hard disk, as long as you set up a customized time interval, the module can be automatically stored in high-definition video and pictures in accordance with the format, to improve the convenience of the operation of the manual late quality traceability.
BLT-Intelligent Recoating Detection, BLT-3D Reconstruction and BLT-Video Monitoring cover the whole time period of process quality monitoring and can be connected to the BLT-MES system, so that users can grasp the production status in real time, which is convenient for remote inspection and later quality traceability. BLT’s process monitoring system combines software and hardware to optimize process parameters with advanced technology, ensure a more stable manufacturing process, and achieve high-efficiency and low-cost manufacturing of aerospace and aviation components.
