In Direct Metal Laser Sintering(DMLS),the metal powder is melted together by a laser in the printer to create 3D object. With the help of roller a super-thin layer of Aluminum or Titanium powder is spread all over the build chamber. The print chamber of the 3D printer is then heated below the melting of the powder. Now the process of sintering is done with the help of laser that touches those areas of the layer,raising the temperature just above the melting point of the part design. Thus, one layer of the part is sintered.
The process of spreading of powder, laser sintering of the object is continued until the complete object is build. It is not possible to yield the 3D print immediately after the completion of print. As we heated up the chamber earlier, the printer and the metal parts are allowed to cool down. Once the duration for cooling is completed,the object is lifted from the powder bed. If any support structures are given to the object to keep structurally strong while the printer builds it, those will be removed manually.
