【 摘 要 】

Rapid Prototyping (RP) is a special technology which has many types included Direct Metal Laser Sintering (DMLS). The process starts by applying a very thin layer of material onto the construction platform, then fusing the powder at the exact points specified by the CAD model. After that, the platform is lowered and another layer of the substance is laid restarting these steps till the desire model is ready. Nowadays Additive Manufacturing (AM) expression is used instead of RP, because it is characterizing much better the process. This paper focuses on the microstructure, and EBSD examination of Ti-6Al-4V (Grade 5) samples produced with DMLS technology. Our main aim was to compare the properties of AM produced samples to the properties of traditional Grade 5 titanium alloy.
