3D laser beam melting
selective laser melting (SLM)
definition |
|
The Selective Laser Melting (SLM, synonym Selective Laser Sintering = SLS) belongs to the technology family of generative production techniques. The three dimensional constructional part is generated by a laser beam (lamda = 1068 nm), which melts completely layers of metal powder. This offers the possibility to create complex structures and shapes in only one production step (near net shape). Because of this advantage this technique is commonly used for rapid prototyping. It is expected in the future that the potential of this technology will be useful for Additive Layer Manufacturing (rapid tooling and rapid manufacturing). |

At the beginning, a three dimensional CAD or CT model and will be sliced into 30-50 μm thin layers. Each layer has specific laser beam information which includes the detailed melting properties. Our team use the SLM 250 HL machine from the MTT Technology Group. |
