Metal 3D Printing

How Does 3D Metal Printing Work?

3D metal printing is a method of additive manufacturing that allows parts to be built more quickly and efficiently than by utilizing CNC machining. The process creates prototype and production metal parts by using a laser to selectively fuse a fine metal powder. While traditional methods of manufacturing remove material from a piece of stock metal, 3D metal printing processes such as direct metal laser sintering builds parts from the ground up.

This allows for the production of parts with very complex geometries, such as integrated fastening features, custom contours, and metal mesh structures. Using metal 3D printers allows for production of assemblies in a single part form, reducing the number of parts, assembly time, and opportunity for failures. Additionally, since metal 3D printed parts do not require tooling, the initial part manufacturing lead time can be reduced from months to days.

Metal 3D Printing Applications

Rapid Tooling

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

Rapid Prototyping

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

Direct Digital Manufacturing

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

Metal 3D Printing 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.


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

Complex Geometry

Produces parts that cannot be made using traditional manufacturing techniques.


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

Metal 3D Printing Finishes


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

Additional Finishes

Additional post processing, such as CNC Machining of features and polishing, are evaluated on a case-by-case basis. For examples of our additional finishes, please refer to the DMLS section of our photo gallery.
