No Tooling or Fixturing
DMLS builds parts straight from your CAD file, so there are no dies or fixtures to wait on. That cuts lead time and cost, and lets us print several design revisions in a single build.
Direct Metal Laser SinteringServices and Capabilities
Direct Metal Laser Sintering (DMLS) fuses metal powder one layer at a time with a focused laser, building dense, functional parts straight from your CAD file. No hard tooling means fast revisions and tight tolerances on complex geometry.
About Our DMLS Services
In 2004, members of the Evology team brought in an EOS EOSINT M270, one of the first DMLS systems in the United States. We have run the process ever since, building functional metal parts to tight tolerances.
DMLS uses no hard tooling, so we can adjust a design and reprint it without waiting on new dies or fixtures. That keeps revisions fast and short runs affordable.
DMLS is one of several metal additive processes. See how it fits alongside the rest on our manufacturing capabilities page.
Why Choose DMLS?
DMLS earns its place where geometry, weight, and lead time matter more than raw volume. Three traits set it apart from machined and cast metal parts.
Design Flexibility
Because the part grows layer by layer, you can build internal channels, lattices, and consolidated assemblies that are hard or impossible to machine. A design change means a file change, not new tooling.
Range of Alloys
We print aluminum, maraging and stainless steels, Inconel, and titanium, so you can match the alloy to the load, temperature, and corrosion demands of the part.
Applications of DMLS
DMLS suits functional metal parts where the design carries complex internal features or has to hold up under heat, pressure, or load. Here is where it earns its place most often.
Heat Exchangers
Dense metal parts with internal channels that move heat efficiently inside a compact envelope.
Conformal Cooling Inserts
Mold inserts with cooling channels that follow the part, cutting cycle time and reducing warp.
Drill Bits
Custom cutting tools and bits in tool steel for specialized drilling and machining work.
Casting Replacements
Functional metal parts that stand in for castings without the tooling cost or long lead time.
Functional Metal Parts
Load-bearing components in aluminum, steel, Inconel, or titanium for demanding service.
Technical Specifications
DMLS is a powder-bed process that fuses metal one layer at a time with a focused laser, closer to micro welding than to casting or machining. The result is a dense, structurally sound part that holds tight tolerances.

Our Experience & Capacity
We have run DMLS since 2004 and have grown the fleet as demand has grown, which lets us take on larger builds and react quickly to tight schedules. Our parts ship into automotive, aviation, defense, and medical programs.
Whether you need a single functional prototype or a recurring production part, we can scope the build and recommend the right alloy. Explore the rest of our manufacturing capabilities to see how DMLS pairs with our other additive and traditional processes.
See DMLS at work in our case studies, from a Baja rear knuckle that cut weight 86% to a structural Formula SAE oil pan.
