The DMLS machine begins sintering each layer—first the support structures to the base plate, then the part itself—with a laser aimed onto a bed of metallic powder. After a cross-section layer of powder is micro-welded, the build platform shifts down and a recoater blade moves across the platform to deposit the next layer of powder into an inert build chamber. The process is repeated layer by layer until the build is complete.
Support structures are automatically generated and built simultaneously in the same material, and are later manually removed. An initial brushing is manually administered to parts to remove a majority of loose powder, followed by the appropriate heat-treat cycle while still fixtured in the support systems to relieve any stresses. Parts are removed from the platform and support structures are removed from the parts, then finished with any needed bead blasting and deburring. Final DMLS parts are near 100 percent dense.
This technology combines the design flexibility of 3D Printing with the mechanical properties of metal. From tooling inserts with cooling channels to lightweight structures for aerospace, any application that involves complex metal parts potentially benefits from Metal 3D Printing.

It depends on 2 factors quantity & complexity of parts. For < 10 parts DMLS is cost effective. When the requirement is mass i.e. > 1000 casting will be cheaper.
For simple geometries like a 50 mm Dia x 50mm Length shaft DMLS cost 15,000 bucks where as in casting or machining it may cost max 2,000 bucks. So for complex geometries DMLS will be cheaper.
After DMLS printing there are a series of secondary process involved which comes time. Below mentioned are series of steps we do in DMLS printing process.
