Faster Metal Parts

Direct Metal Laser Sintering (DMLS) is a 3D printing technology that uses metal powders and precision lasers to quickly and accurately create complex parts from a 3D CAD file.

Advantages of DMLS

DMLS can easily be called the best thing that has happened in digital manufacturing and design innovation.
It is perfect for manufacturing digital 3D models into production parts and prototypes, when durability and strength are critical.



DMLS parts do not require tooling, reducing manufacturing lead time from months to days.


Utilizes powdered metals with strong mechanical and dynamic properties, making it perfect for end-use parts.

Complex Geometries

Produces parts that cannot be made using traditional manufacturing techniques.



Enables all-in-one assemblies that reduce parts count, assembly time and opportunity for failures by combining multiple parts into a single design.

Rapid Turnaround

Stainless steel part are built within 5 business days, and aluminum parts are built within 8 business days, allowing for faster innovation and speed to market.





Rapid Tooling

Because DMLS printers can print in metal, they are widely used for rapid tooling, i.e., creating injection molds.

Rapid Prototyping

DMLS printers are used to make proof of concept models and fully functional late-stage prototypes.

Direct Digital Manufacturing

High-quality finish and durable materials have made DMLS printing a favorite technology for end-use products.



Material Details

Stainless Steel 17-4

Material Details


As Built

Minimal post processing takes place. Support structures are removed and the parts are lightly sanded.


In addition to the removal of support structures, the part surface is media blasted to provide a uniform finish.


Xometry can provide additional post processing including CNC machining of features and polishing.
