Selective Laser Melting in Powder Bed
Selective laser beam melting in a powder bed is a manufacturing process where metal powder is melted layer by layer with a focused laser. This enables the precise production of complex components with high density.
Physical-Chemical Mechanism of Action
A focused laser beam melts the metal powder in a limited area. The melting processes are selective and controlled, which enables high precision.
Metallurgical Relevance & Risks in Welding
The method allows the production of components with a high degree of density and accuracy. However, inaccurate focusing or too high speed can lead to distortions or missing melt spots, which affects quality.
Workshop Practice & Operating Instructions
Use a focused laser beam with a power of 100 to 400 watts. The powder density should be between 2 and 3 g/cm³. A melting speed of 50 to 100 mm/s is typical. Make sure the laser beam is focused precisely on the desired area.
