Direct Metal Laser Solidification (DMLS®)

DMLS

Direct Metal Laser Solidification (DMLS®), is the process of manufacturing metal parts from 20-40-micron powders with 400W lasers. These lasers fuse microlayers of fine metal together to create complex geometries from 3D design files. Because DMLS® melts and forges metal powders repetitively, the process ensures 99.9% uniquely uniform densities throughout the parts.

The powdered metal is first spread by a sliding arm on the print platform. Then, the powdered metal is laser fused and lowered by a distance equal to a single micron powder layer. This entire process is repeated on tens of thousands of layers until a fully-functional production part is formed. Once the process is finished, the part is ready to be Wire EDM precision-cut from the build platform.

DMLS® machines produce parts that are known for their strength, hardness, and densities–each of which are comparable to or better than those of machined, cast, or forged parts of similar metals. In many cases, the rapid solidification rate, after the laser fusing, creates a very fine crystal structure with superior strength to forged or cast components. If the DMLS® part is heat treated, its density, durability, and strength are even greater.

Because of the superior quality and unique manufacturing process, DMLS® machines allow for design freedom. Designs can be built hollow or filled for even higher strength-to-weight ratios. From aerospace to firearms, find out how DMLS® can is used in your industry.

EOS DMLS® M280

Direct Metal Laser Sintering M280

The EOS M280 is the work horse of EOS Direct Metal Laser Solidification (DMLS®) printers. It produces production parts using fully automated laser sintering driven by Solidworks CAD files, no CNC programming, no tool changes necessary.

Constant system self-monitoring of the build process ensures that all parts are printed in fully functional, reproducible quality. 3D metal printing allows clients to design and manufacture products with extremely complex geometries including free-form surfaces, lattice and honeycomb structures, deep slots, and conformal cooling channels.
