Direct Metal Laser Sintering (DMLS)

Direct Metal Laser Sintering, a component of additive manufacturing technology which can manufacture parts out of metals and alloys from 3D designs without using tools. This process requires orientation of 3D Model and addition of support structures wherever necessary. This technology fuses each layer of metal powder into a solid part.

Utilizing a wide variety of metals like Stainless Steel, Aluminium, Titanium and alloys like Inconel, DMLS technology provides strong and durable metal parts. If the use case is functional metal prototypes, high-temperature applications, and user-oriented parts, DMLS is an optimum choice. Since DMLS uses quite a few alloys, prototypes can be made out of the same material as production components. The ability to generate functional metal prototypes in short time radically impacts design processes accelerating design cycles and time to market.

How does it work?

  • The Process begins by slicing 3D CAD data into layers. A program takes 3D CAD data and mathematically slices it into 2D cross-sections.

  • Each section acts as a blueprint for the DMLS, instructing the machine the location to sinter the material.

  • Once the data is transferred to the machine, a roller assembly pushes the powdered material from the material source to create a layer on the base.

  • In the next step, the laser creates a 2D cross section on the perimeter of the part.

  • After completion of every layer, the base plate is goes down by a few microns for the next layer to be complete.
