SLM

Hunan Farsoon Co., Ltd. focuses on the research, development, production and sales of industrial-grade additive manufacturing equipment, providing metal (SLM) additive manufacturing equipment and polymer (SLS) additive manufacturing equipment to global customers, as well as 3D printing materials, processes and services. The company has developed more than 20 types of equipment and more than 40 types of special materials and processes. Its products are being rapidly applied in aerospace, automotive, medical, mold, sports shoes, electronics and other fields. It is one of the few additive manufacturing companies in the world that has the independent research and development and production capabilities of 3D printing equipment, materials and software.

In selective laser melting (SLM), infrared (IR) thermal imaging provides key benefits:
  1. Real-time Melting Pool Monitoring: IR captures precise temperature dynamics of the molten pool, enabling immediate adjustment of laser power to prevent defects like porosity or uneven solidification.
  2. Layer-by-Layer Defect Detection: IR imaging identifies thermal anomalies (e.g., insufficient fusion, hot spots) in real time, ensuring each printed layer meets quality standards.
  3. Process Stability Optimization: By analyzing IR thermal data, operators optimize laser scanning speed and energy density to minimize warping and improve part dimensional accuracy.
  4. Non-destructive Quality Control: Non-contact IR monitoring allows continuous in-process inspection, reducing reliance on post-print testing and enhancing production efficiency.
