When we debuted metal 3D printing, we were blown away by your overwhelming interest and excitement.

Since then, we’ve put together this brief post to help inspire and inform your decisions when designing for DMLS (Direct Metal Laser Sintering) 3D printed parts.

Xometry offers DMLS in both 17-4 stainless steel and lightweight aluminum alloy (AlSi10Mg).

Part Consolidation

Combine assemblies comprised of multiple components into a single, lightweight, printed part– all while retaining or exceeding the robustness of the original assembly.

Complex Geometries with 3D Printed Aluminum

Complex Geometries and Interior Structures

The freedom to design and manufacture complex geometries and intricate interior structures is one of the great promises of additive manufacturing. 3D printing technologies allow you to create parts impossible to manufacture any other way. Think outside the box!

How 3D Printing Aluminum with DMLS works


Like all additively manufactured parts, there’s no custom tooling or mold making involved, so your parts are made on-demand. It is an even faster alternative to CNC machining.

The final product is comparable to a metal casting in terms of fit and finish, and can be post-processed like any other metal part.

  1. Raw: This is the part before any finishes are applied.
  2. Bead Blast: Our standard finish that leaves the part looking bright and clean.

Large Build Volume available with 3D Printed Aluminum

Build Volume

Unique to Xometry, we can build aluminum 3D printed parts up to 6″ x 6″ x 6″, and stainless steel up to 9" x 6" x 6";. We're among the few manufacturers in the US with this capability.

Instant Quoting with 3D Printed Aluminum

Instant Quoting

Another feature unique to Xometry is automatic and instant quoting on metal 3D printed orders. Just upload a 3D CAD file and select either stainless steel or aluminum DMLS to get a price in seconds.
