Direct Metal Laser Sintering (DMLS) icon

Direct Metal Laser Sintering (DMLS) uses a precise, high-wattage laser to micro-weld powdered metals and alloys to form fully functional metal components from your CAD data. DMLS eliminates time-consuming tooling, and creates complex geometries not possible with other metal manufacturing processes. Made from materials like Inconel, Aluminum, Stainless Steel, and Titanium, DMLS parts are strong, durable, and heat-resistant. DMLS parts are also denser than investment casted metal parts. This accurate metal 3D printing process provides fine feature detail, making it ideal for complex oil and gas components, custom medical guides, consolidated aerospace parts, and tough functional prototypes.

Benefits of DMLS

Design Freedom

Build real metal parts without conventional manufacturing limitations. With DMLS, you can create durable, intricate metal parts that until now, were difficult or impossible to fabricate with other manufacturing processes.

Streamlined Manufacturing

Consolidate design and optimize value. As a 3D printing technology, DMLS allows you to integrate multiple components – such as mountings, fasteners, and sectioned parts – into a single, strong metal part. This reduces weight, cuts down waste, and saves the time and resources needed for assembly.

Functional Parts, Fast

Cut lead times and get results. From prototypes to low-volume production parts, DMLS can accelerate your project’s design and manufacturing timeline. Build tough, hard-working prototypes to test components in real-world applications, and eliminate time-consuming tooling for low-volume production parts.


Raw parts have a surface finish comparable to a fine investment cast part, but expert finishing services are crucial for a successful end-use component. This is partly why DMLS is not feasible for many companies and firms to take in-house with their own 3D printing operations, but Stratasys Direct Manufacturing has the resources and experience you need. We offer a variety of professional finishing options, such as media blasting, electroplating, polishing, and CNC machining. Parts can also be heat treated in order to maximize mechanical properties.

DMLS Applications

DMLS is a great solution for complex metal parts you can’t build with conventional manufacturing technologies.

3D printed metal part
  • Common applications include:
  • Parts with cavities, undercuts, draft angles
  • Fit, form, and function models
  • Tooling, fixtures, and jigs
  • Conformal cooling channels
  • Rotors and impellers
  • Complex bracketing

Working with machine

SCHIVO is also delighted to announce a partnership with Waterford’s Institute of Technology South Eastern Applied Materials Research Centre (SEAM) and the availability of an EOS INT M 280 Direct Metal Laser Sintering (DMLS) metal 3D Printing machine.

The EOS M 280 can produce parts up to a volume of 250 x 250 x 325 mm. The wide range of materials from light metals to super alloys includes maraging steel for toolwork and mechanical engineering, to stainless, Inconel and Cobalt, Chromium and Nickel steel alloys and titanium.

These features makes 3D DMLS ideal for such sectors as aerospace, medical and industrial end use. The benefits include cost reduction, lightweight design and tool less production.
