Metal 3D Printing with Direct Metal Laser Sintering (DMLS)
Direct metal laser sintering (DMLS) is an industrial metal 3D printing process that builds fully functional metal prototypes and production parts in 7 days or less. A range of metals produce final parts that can be used for end-use applications.
How Does Metal 3D Printing Work?
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.
When the build finishes, 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.
