Direct Metal Laser Sintering Dmls Technology

In this process powdered metal free of binder or fluxing agent is sintered by the scanning of a high power laser.

Direct metal laser sintering dmls technology.

A part created using direct metal laser sintering. Direct metal laser sintering dmls is an additive 3d metal printing technology that builds prototype and production metal parts from a cad file producing complex geometries without the need for tooling. Direct metal laser sintering dmls direct metal laser sintering dmls is an additive manufacturing technique that uses a yb ytterbium fiber laser fired into a bed of powdered metal aiming the laser automatically at points in space defined by a 3d model melting or rather welding the material together to create a solid structure. Direct metal laser sintering was patented by erd and eos back in 1994 before eos pioneered the technology in their dmls 3d printers.

The direct metal laser sintering technology is extremely innovative and offers the opportunity to realize not only prototypes but also final metal parts without the necessity of developing tools or moulds dmls is a so called free form fabrication technology which permits the manufacturing of free and complex shaped parts internal concavities and channels impossible to realize with the traditional fabrication methods. Dmls uses a laser to selectively fuse a fine metal powder in either stainless steel or aluminum materials. Direct metal laser sintering dmls was developed jointly by rapid product innovations rpi and eos electro optical system germany starting in 1994 as the first commercial rapid prototyping method to produce metal parts in a single process. Dmls technology is well known as a leading technology implementing in the direct hard tooling an application known as direct tool.

As a growing additive manufacturing technology dmls is predicted to nearly double in its use by 2018. This process is an advancement of powder metallurgy a mature metal moulding technology that uses heat and pressure to form powdered metal parts. Direct metal laser sintering dmls was developed jointly by rapid product innovations rpi and eos gmbh starting in 1994 as the first commercial rapid prototyping method to produce metal parts in a single process. The dmlm process is very similar except that the material is completely melted to create ultra thin liquid pools which solidify as they cool.

Direct metal laser sintering dmls is one of the few 3d printing technologies that directly create a metal part from its 3d computer model. Dmls was developed by elextrolux rapid development and the eos firm of munich germany. The direct metal laser sintering dmls process uses lasers to partially melt particles so they adhere to one another.
