Principle of Metal 3D Printing
Metal 3D printing is a metal material additive manufacturing technology that is achieved through the selective laser melting (SLM) process. In this process, the laser beam is focused on the metal powder bed and scanned layer by layer along a predetermined path. During the scanning process, the laser energy melts and solidifies the metal powder to form a dense metal part.
Advantages of Metal 3D Printing
The advantages include: high precision, high efficiency, customizability, this technology can directly produce dense metal parts without traditional manufacturing processes such as cutting or EDM, thereby reducing production costs, while also saving resources, reducing waste generation, and benefiting environmental protection. Therefore, metal 3D printing has become one of the mainstream technologies for manufacturing metal parts with complex shapes and has received widespread attention.
Working steps of metal 3D printing
1. Laser scanning: First, use a laser to focus the beam on the metal powder bed and scan it layer by layer along a predetermined path.
2. Powder bed melting: The energy of the laser beam melts and solidifies the metal powder, gradually forming a dense metal part.
3. Solidification of metal parts: After the powder bed forms dense metal parts, cooling measures are taken to make them solidify quickly to form complete metal parts.
4. Cutting and forming: Finally, the metal parts can be separated from the substrate by cutting or forming.
Through the above four steps, the 3D printing process from metal powder to formed metal parts can be realized.
