Özet
Additive manufacturing techniques, which have gained popularity in recent years, are all of the technology obtained by means of adding a certain material, such as plastic or metal, to each other. It was first produced in 1984 and today, many companies continue to produce and sell 3D printers and R & D services. In recent years, the market volume of additive manufacturing reached $ 2.2 billion, an increase of 29%. With additive manufacturing technologies, there is a serious demand and investment especially in the fields of Medicine, Aerospace, mold making, Automotive, Dentistry, Military equipment, Architecture, Personal tools, Sculpture, jewelry and Education. In the production stage of the materials, the 3D Model is first converted into an STL format file, which is the add-on manufacturing standard interface. Then, with the support of a laser that can move in x, y, z coordinates, the metal powders on the surface of the printer are sintered and the material is prepared. Different types of AM processes are available. The most popular are Powder Bed Fusion, Material Jetting, Stereo lithography (SLA), Directed Energy Deposition (DED) and Material Extrusion. In this study, we examined and reported the mechanical and characteristic properties of the sample printed by Direct Metal Laser Sintering (DMLS) method which is a member of Powder Bed Fusion system by using F357 aluminum-silicon metal powder and F357 powder with various test methods. EOSINT M270 in IIT, Turin was used as a printer and the material that we received from this printer was analyzed and reported together with the F357 metal powder. Throughout the report, various techniques such as Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Differential Scanning Calorimeter (DSC), and Vickers Hardness Indentation were used to find the characterization and mechanical properties of the material. The results which obtained were explained in detail to form the basis for future studies
