Direct Metal Laser Sintering or DMLS is an industrial metal 3D printing technology. It is a powder bed fusion process similar to SLS, which builds parts from a range of metal materials one layer at a time by sintering metal powders together.
DMLS 3D printing is a process capable of building highly complex shapes which would be near impossible to make via other methods. This technology promises to have a massive range of applications as it improves and becomes better understood.
|Maximum Build Size||280 x 280 x 280 mm (11″ x 11″ x 11″)|
|Lead Time||3 days|
|Prototyping Applications||Complex-shaped functional prototypes for testing|
|End-Use Applications||Low volume functional end-use parts|
|Sanding||All||–||Sanding DMLS printed parts is a good way of smoothing edges, minimizing visible layers, and getting rid of any leftover support marks.|
|Spray Painting||All||Black, Pantone/RAL colours||Spray painting is a quick way to colour DMLS parts. It can also reach areas that cannot be reached with a brush.|
|Plating||All||–||Polishing is often used to enhance the appearance of an item, create a reflective surface or prevent corrosion.|
To achieve better part quality and dimensional accuracy, it is important that your 3D model closely follows a set of geometric recommendations. Learn actionable design tips for DMLS and SLM.
Direct Metal Laser Sintering (DMLS) is a metal 3D printing technology that uses lasers to fuse powdered metals into functional prototypes and low-volume end-use parts.
Metal printing defies traditional Design-For-Manufacturing guidelines, so designs that would typically be made in assemblies can be made in a single piece.
DMLS and SLM produces parts that cannot be made using traditional manufacturing techniques.
Metal 3D printed parts do not require tooling which reduces the manufacturing lead time from weeks to days, allowing for faster innovation and speed to market.
SLM and DMLS utilizes powdered metals with strong mechanical and dynamic properties, making it perfect for end-use parts.
Direct Metal Laser Sintering, or DMLS, is an additive manufacturing technology that produces functional metal prototypes and low-volume production parts by melting and fusing layers of metallic powder together through a high-power laser beam.
Ultimately, Direct Metal Laser Sintering (DMLS) and Selective Laser Melting (SLM), often used interchangeably, are very similar additive manufacturing processes. They both use laser energy to add metal powder together rapidly. The main difference is that SLM heats the metal powder until it fully melts into a liquid, whereas DMLS just sinters heat particles enough so that their surfaces weld together.
At HLH, we offer both DMLS and SLM 3D printing services.
DMLS can produce complex-shaped and functional metal alloys or pure metal prototypes and low-volume end-use parts.
