DMLS 3D Printing Services

Direct Metal Laser Sintering (DMLS) is a metal 3D printing technology that selectively fuses a fine metal powder in aluminium or stainless steel. This 3D printing technology is used to manufacture both prototypes and production parts, especially with very complex features and all-in-one assemblies.

Advantages of DMLS with Xometry

Massive Capacity

Massive Capacity

We can quickly produce both prototypes and large batches thanks to the largest manufacturing network in Europe, with over 2000 vetted partners

Fast Production

Fast Production

You will get your 3D printing fast delivered in as fast as 3-5 days.

Quality Assurance

Quality Assurance

We have strong QA procedures, controlled by an in-house team of QA engineers, which allows us to deliver high quality parts.

Engineering Check & Status Updates

Engineering Check & Status Updates

All designs are checked by engineers before they’re sent for 3D printing. After confirming your order, you will receive status updates on your production.

DMLS Materials

  • Aluminium AlSiMG | EN AC-43000 | DIN EN 1706:1998
Steel & Stainless Steel
  • Tool Steel MS1 | 1.2709
  • Stainless Steel 17-4 | 1.4542

Pros & Cons of DMLS 3D Printing

Complex Geometries: DMLS makes it possible to manufacture parts that cannot be produced with subtractive manufacturingSurface roughness is higher than with CNC machining
Powdered metals used for DMLS 3D printing possess strong mechanical propertiesHigher costs than other manufacturing technologies
Variety of mechanical and electro-chemical post-processing options applicable for final part enhancementLimited volume size
