What is Direct Metal Laser Sintering?

Direct metal laser sintering (DMLS) is an additive manufacturing technique that is also referred to as selective laser melting (SLM). It is suitable for metals production. In this process, each layer of a part is created by aiming a laser at the powder platform in specific points in space, followed by a digitally produced CAD file.


It offers good accuracy and excellent mechanical properties. It is can be fully used for end-use applications. Contact Xinpin Model for the price, one of the professional direct metal laser sintering suppliers.

The Advantage of DMLS


  • 1. Support Impossible Structure

Such as overhanging and hollow geometry.

  • 2. Quick Delivery Date

DMLS parts are often turned in 1-3days.

  • 3. Recyclable Material

The material is reusable for a metal powder that is not sintered or melted.

Direct Metal Laser Sintering Process


The DMLS machine begins the 3d metal printing process by sintering each layer—first the support structures to the base plate, then the part itself—with a laser aimed onto a bed of metallic powder. After a cross-section layer of powder is micro-welded, the build platform shifts down and a recoater blade moves across the platform to deposit the next layer of powder into an inert build chamber. The process is repeated layer by layer until the build is complete.

FAQs of DMLS 3D Printing

1 How strong is DMLS?

Fusing together fine layers of powder, DMLS has the ability to produce very strong and accurate parts (± 0.05 mm/0.002 in.), from simple to complex geometries. This makes it a great alternative to machining parts.

2 What is direct metal laser sintering used for?

Direct metal laser sintering (DMLS), also called selective laser sintering (SLS), is a type of metal additive manufacturing or 3D printing. It's used for both rapid prototyping and mass production of metal parts.

3 How do parts made by DMLS compare to cast parts?

Parts that are printed using direct metal laser sintering are stronger, denser, and can be more precise than casted metal parts.
