Selective Laser Melting
Selective laser beam melting is a process where metal powder is melted by a laser beam. This results in dense, fine-structured components.
Physical-Chemical Mechanism of Action
A laser beam with high energy ensures the complete melting of metal powder particles. The powder particles are heated to a temperature in a very short time at which they change to liquid and fuse together.
Metallurgical Relevance & Risks in Welding
This process enables the precise shaping of components with a high resolution. It reduces the risk of porosity and improves the mechanical properties of the material. However, an inaccurate focus or too high energy settings can lead to overheating and distortion.
Workshop Practice & Operating Instructions
Use a high-precision laser with a stable, calibrated beam. Make sure the powder is fine and clean. Keep the energy settings constant and monitor the temperature of the material continuously. Avoid cooling too quickly or too slowly to ensure a homogeneous structure.
