DMLS Produces High-Quality Metal Parts Without Tooling

Direct metal laser sintering (DMLS) is a metal 3D printing technology used to build metal parts with exceptional mechanical properties and precision. Our Manufacturing Supplier Network gives you massive on-demand production capacity with a wide range of DMLS machines and high-performance materials.


Designers often chose DMLS for its ability to produce all-in-one metal assemblies and highly precise metal parts with complex features like internal supports and lattices. DMLS does not have upfront setup or tooling costs, making it an affordable option for fully dense metal parts, with the design freedom of additive manufacturing. With DMLS’s affordability, speed, and superior design freedoms, companies and creators can build metal designs they never thought possible and produce accurate metal components.

    This table depicts the general tolerances for Direct Metal Laser Sintering (DMLS). Stresses during the build and other geometry considerations may cause deviation in tolerances and flatness. Part designs with thicker geometries, flat or broad parts, and parts with uneven wall thicknesses may be prone to significant deviations or warp. Improved tolerances may be possible with a manual quote review, after successful completion of a prototype build, and must be approved on a case-by-case basis. General tolerances apply before secondary finishing or post-processing unless otherwise specified. Please check out Xometry's Manufacturing Standards for more information on tolerances per process.

    How a Direct Metal Laser Sintering Machine Works

    Direct metal laser sintering (DMLS) is an additive metal printing technology that builds metal parts from a CAD file by selectively fusing stainless steel or aluminum powder into thin layers. 

    Direct metal laser sintering’s layer-by-layer printing allows multiple parts to be combined during the printing process. With traditional manufacturing processes, metal parts are machined or metal casted into several parts and assembled. Printing an all-in-one assembly strengthens the finished part while reducing the weight and cost of production significantly. DMLS techniques can also create parts at a high density. This is ideal for parts under high pressure such as in oil and gas industries.

      Best Applications for DMLS

      Rapid tooling

      Rapid Tooling

      Because DMLS parts are strong yet lightweight, they are widely used for rapid tooling, fixtures, and jigs.

      Fast parts and fast shipping

      Rapid Prototyping

      DMLS metal laser printing is typically affordable and fast, and therefore is often used to make proof-of-concept models and fully functional late-stage prototypes.

      Digital manufacturing

      Production

      Cast-quality finish (fully dense) and durable materials make DMLS printing a favorite technology for end-use products.
