DMLS Is the Future of 3D Printing

    What Is Direct Metal Laser Sintering?

    Direct Metal Laser Sintering (DMLS) is a direct metal laser melting (DMLM) or laser powder bed fusion (LPBF) technology that accurately forms complex geometries not possible with other metal manufacturing methods.

    DMLS parts are stronger and denser than investment casted metal parts, and they can help you get to market first with faster turnaround times.

    Metal 3D printing is an ideal process for complex oil and gas components, custom medical guides, part-consolidated aerospace parts and tough functional prototypes.

    Advanced Metals with DMLS

    How Does Direct Metal Laser Sintering Work?

    DMLS uses a precise, high-wattage laser to micro-weld powdered metals and alloys to form fully functional metal components from your CAD model.

    DMLS parts are made with powdered materials like aluminum, stainless steel and titanium, as well as niche alloys like MONEL® K500 and INCONEL® 718.

    Finishing DMLS Parts

    Raw DMLS parts have a surface finish comparable to a fine investment casting part, and expert finishing services are sometimes needed.

    Stratasys Direct offers a full suite of professional finishing operations, including precision machining, media blasting, surface grinders and milling.

    Direct Metal Laser Sintering Quality Controls

    To maintain critical quality control standards, we use a range of tools to inspect and ensure customer specifications.

    With international certification standards ISO 9001 and AS9100, we have stringent systems in place to guarantee quality and consistently are met.

    We utilize tools like coordinate measuring machines, probes, cutup metallography processes and flow benches, hydrostatic pressure testing machines to guarantee quality is consistently met.

    Metals Like You’ve Never Seen Before with DMLS

    DMLS materials build fully dense, corrosive resistant and highly robust metal parts that can be further treated through heat, coating and sterilization.

    DMLS Frequently Asked Questions

    Are DMLS parts as strong as traditionally manufactured metal components?

    Yes. The parts created with DMLS have mechanical properties equivalent to a cast metal part. Detailed information can be found on the DMLS materials page. 

    What is the porosity of DMLS parts?

    DMLS parts can reach a 99.5% density. In fact, 3D printed metals are above industry standards for density testing.

    What level of detail can be obtained with DMLS?

    DMLS is available in several resolutions. At its highest resolution, the layer thickness is 0.0008” – 0.0015” Z and the X/Y resolution is 0.012” – 0.016”.

    The minimum hole diameter is 0.035” – 0.045”. Read the DMLS design guidelines to learn more.
