What is DMLS 3D Printing?

Direct metal laser sintering services (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.

Xin Pin is one of leading direct metal laser sintering suppliers and direct metal laser sintering manufacturers, providing DMLS printing service with good accuracy and excellent mechanical properties. It is can be fully used for end-use applications. DMLS for sale from one of the professional direct metal laser sintering suppliers.

Difference between DMLS and SLM

DMLS and SLM are both powder bed fusion technologies that melt metal powder with lasers. SLM machines often have more powerful lasers than DMLS (1000 watts vs. 400 watts). The output power of the SLM lasers can also be adjusted to change the part's detail resolution.

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 into 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 DMLS manufacturing process of 3D printing parts China 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 bulk 3D printing service. 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.
