Direct Metal Laser Sintering
Direct metal laser sintering (DMLS) is an industrial 3D printing process that builds fully functional - rapid 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.
DMLS design guidelines will help you understand capabilities and limitations.
Why Choose DMLS For Your 3D Printing Project?
DMLS materials are generally accepted to be equal or better than those of wrought materials. DMLS is also ideal when the geometry or structure of the part is not possible in any other process (for weight saving designs using honeycomb or latice structures for example). Protolabs can also produce parts for implant medical applications. We offer a range of secondary CNC machining services to further enhance your DMLS project.
DMLS material data sheets can be found in our Material Comparison Guide
How Does Metal 3D Printing Work?
The DMLS machine begins begins the 3d metal printing process by 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.
