Direct Metal Laser Sintering Dmls Technology

This process is an advancement of powder metallurgy pm a mature metal molding technology that uses heat and pressure to form powdered metal parts.

Direct metal laser sintering dmls technology.

It s a type of powder bed fusion in which a laser achieves full melt of the powdered metal to form a homogenous part. Many major valuable 3d printing companiesincluding 3d systems slm solutions concept laser and eos sell dmls metal 3d printersthat are able to create incredibly intricate metal parts and 3d printed jewelryfrom precious metals. Selective laser melting slm also known as direct metal laser melting dmlm or laser powder bed fusion lpbf is a rapid prototyping 3d printing or additive manufacturing am technique designed to use a high power density laser to melt and fuse metallic powders together. The direct metal laser sintering dmls process uses lasers to partially melt particles so they adhere to one another.

If you are interested in getting parts made call your current service provider who can work with you on dmls parts. Selective laser sintering sls is an additive manufacturing am technique that uses a laser as the power source to sinter powdered material typically nylon or polyamide aiming the laser automatically at points in space defined by a 3d model binding the material together to create a solid structure it is similar to selective laser melting. Direct metal laser sintering dmls is one of the few 3d printing technologies that directly create a metal part from its 3d computer model. Like in the sls process your metal part will be created layer by layer according to your 3d model.

A major difference is the sintering temperature. It creates parts additively by sintering fine metal powder particles to fuse them together locally. 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 is the most widely used metal 3d printing technology.

The two are instantiations of the same concept. Direct metal laser sintering dmls is a direct metal laser melting dmlm or laser powder bed fusion lpbf technology that accurately forms complex geometries not possible with other metal manufacturing methods. It is a highly popular 3d printing technology and achieves great results with mechanical properties above casting grade components and nearing wrought properties.
