Additive manufacturing is the process of building a component or a product layer-by-layer, as opposed to casting the component and then performing various subtractive machining processes like turning, drilling, milling which are the approach of subtractive manufacturing. The term 3D printing refers to the family of additive manufacturing processes, which utilize different mechanisms in order to build the product from a sliced computer aided design (CAD) model fed to the machine. direct metal laser sintering (DMLS) is the one method of 3D printing functional metal parts are suitable for engineering applications and has the potential to provide a viable alternative to conventional methods of manufacturing and produce superior quality components with great flexibility in design using a wide range of materials. This paper presents the overview of DMLS technology, process parameters, design considerations, case studies of parts manufactured by DMLS and its applications in metal casting and rapid tooling.Keywords
Additive manufacturing; direct metal laser sintering; metal 3D printing.

Fatigue is a process of progressive localized plastic deformation occurring in a material subjected to cyclic stresses and strains at high stress concentration locations that may culminate in cracks or complete fracture after a sufficient number of fluctuations. Fatigue testing is carried out using the ASTM D3479 with a notch or crack for investigating the initiation of crack. Several fatigue tests were conducted in tension-tension and/or tensioncompression loading at a frequency of 10Hz or sinusoidal wave’s frequency of 5Hz, and at constant-amplitude. The fatigue tests were interrupted by the researchers at regular intervals after a predetermined number of cycles to monitor crack advance and to observe the failure modes by various ways such as visual observation, digital camera, traveling microscope, CCD camera, etc.Keywords
