Overview-of-Metal-Additive-Manufacturing-Direct-Metal-Laser-Sintering-(DMLS)-Technology.jpg

Metal 3D Printing is also known as Metal Additive Manufacturing. Metal 3D printing offers digital flexibility and enables the production of lighter and stronger parts. Metal 3D printing is helping us bring design and innovation to the forefront. 

Innovae3D specializes in manufacturing parts using Metal Additive Manufacturing (3D Printing), i.e. Direct Metal Laser Sintering (DMLS) technology. 

Innovae3D has a state-of-the-art manufacturing facility with comprises a DMLS 3D printer: EOS M280. And the entire facility is AS 9100 and ISO 9001:2015 certified! 

In this article, you will get an overview of DMLS technology. 

 

What is Additive Manufacturing? 

Basically, additive manufacturing technology uses 3D model data (computer-aided-design (CAD)) to deposit the material layer-by-layer (in a precise manner). 

As the name suggests, part is created by adding the material, as opposed to the subtractive manufacturing. 

In subtractive manufacturing, we remove material through conventional manufacturing processes like milling, turning etc. to achieve the desired final shape.

Additive manufacturing is also called by the names: 3D Printing, Rapid Prototyping, Direct digital manufacturing, freeform fabrications, etc.

Additive manufacturing has various processes. Here, we will explain you the DMLS process/technology. 

 

What is DMLS Technology? 

DMLS is additive manufacturing technology. This technology is also known as Direct Metal Laser Melting (DMLM).

This technology spreads the metal powder layer by layer and uses a powerful laser beam to melt the thin layer of metal powder.

Here, first, a thin layer of metal powder is deposited on the build platform. A powerful laser beam then melts the metal powder precisely as specified by computer generated design data. Then, the platform lowers by an amount corresponding to the layer thickness of the part geometry and then new layer of metal powder is deposited. This process is repeated until the entire part is created. 

After completion of part printing, loose powder is removed during the post-processing and same can be recycled for the next build. 

You can watch the following video to understand the working principle of DMLS technology.

DMLS technology allows the creation of complex parts with precise geometric shapes using CAD data. Thus, it is transformative approach for the production of lighter and stronger parts.  

If you are you looking for an easy change or revised version of your product, DMLS is the best technology for you.  

DMLS allows engineers to move from the static designs to produce the design which is highly efficient and cost-effective. In traditional manufacturing processes, any modification in design can lead to a significant increase in cost and lead time.

Design freedom is the primary advantage of DMLS technology.  

 

Benefits of DMLS Technology

Because of the unique working principle of DMLS, this technology has many benefits over substrative/traditional manufacturing process. 

  1. Design Freedom – full control over your design 

  2. Part weight reduction

  3. Rapid prototyping

  4. Consolidation of parts/assembly 

  5. Reduce the lead time/short production time 

  6. No tooling 

  7. Strong and durable components 

  8. Superior quality of the part 

 

Summary: 

Metal 3D printing/Additive Manufacturing uses 3D model data to deposit the material in layer-wise fashion. 

Direct Metal Laser Sintering (DMLS) is a Metal Additive Manufacturing technology. DMLS uses powerful laser beam to melt the thin layer of metal powder. 

Because of the unique working principle of DMLS, this technology has many benefits over substrative/traditional manufacturing process. 

DMLS offers design flexibility and enables the production of lighter and stronger parts. Thus, it helps to bring design and innovation to the forefront.
