Direct Metal Laser Sintering (DMLS)
i3D MFG™’ exclusively utilizes EOS M280 and M290 Direct Metal Laser Sintering (DMLS) machines to manufacture metal parts from 20-40 micron powders with 400W lasers that fuse micro-layers of fine metal together to create complex geometries from 3D design files. DMLS parts are typically characterized as having strength, hardness and densities comparable to or better than machined, cast and forged parts in comparable metals. The metal powder is melted and forged over and over again, creating 99.9% uniquely uniform densities throughout the parts.
The powdered metal is spread by a sliding arm on the print platform, laser fused, and then 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 finished and ready to be Wire EDM precision cut from the build platform.
DMLS parts are typically characterized as having strength, hardness and durability that is, at the least, comparable to cast or forged parts in a comparable metal. 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.
