Direct Metal Laser Sintering

Faster Metal Parts for Prototyping, Rapid Tooling, and Digital Manufacturing

How Does Direct Metal Laser Sintering Work?

By definition, Direct Metal Laser Sintering (DMLS) is an Additive 3D metal printing technology that builds prototype and production metal parts from a CAD file using a laser to selectively fuse a fine metal powder in either stainless steel or aluminum materials. A DMLS machine is capable of producing highly complex features and all-in-one assemblies using metal materials that would be difficult to achieve with subtractive manufacturing techniques.

Our DMLS printing service typically offers build volumes up to 250 x 250 x 325 mm, but we may be able to accommodate larger part volumes upon request in the quote. (See our Manufacturing Standards for more details) Find out the cost of the parts you need using DMLS or compare the costs of DMLS vs. SLS. Get a free instant quote today.

DMLS Applications

Rapid Tooling using DMLS

Because DMLS printers can print in metal, they are widely used for rapid tooling, i.e., creating fixtures and jigs.

Rapid Prototyping using DMLS

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

Direct Digital Manufacturing through DMLS

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

DMLS Advantages

Rapid Turnaround

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

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

Strength

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

Complex Geometry

DMLS produces parts that cannot be made using traditional manufacturing techniques.

Efficiency

DMLS defies traditional Design-For-Manufacturing guidelines, so designs that would typically be made in assemblies can be made in a singular piece.

DMLS Materials

Metals

  • Aluminum
  • Stainless Steel

DMLS Finishes

Standard

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

Custom

Additional DMLS post processing, such as CNC Machining of features and polishing, are evaluated on a case-by-case basis.
