Our DMLS 3D Printing Services

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
Resolution ± 0.3mm
Prototyping Applications Complex-shaped functional prototypes for testing
End-Use Applications Low volume functional end-use parts

Metal 3D Printing Materials

Pure Copper

3D printing with pure copper is possible with DMLS and SLM. Copper is a malleable, ductile, and an extremely good conductor of both heat and electricity. It is ideal for heat exchangers and electrical equipment such as wiring and motors.

Bronze

Bronze is an affordable metal 3D printing material option. It's a copper-based alloy that resists corrosion and metal fatigue better and conducts heat and electricity better than most steels. Bronze is commonly used for sculptures, musical instruments, medals and in other industrial applications.

Stainless Steel

At HLH, we can 3D print in different grades of stainless steel. Stainless steel is strong and highly resistant to corrosion and rust, making it ideal for parts that are exposed to different elements for long periods and do not easily break.
Material Reference
FS 316L, FS 420, FS 15-5PH, FS 17-4PH

Typical DMLS Finishing Options

Applicable Materials Colour Description
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.

Post-Process Machining

DMLS and SLM can produce accurate parts to 0.1mm. Achieve even tighter tolerances with our in-house cnc machining services while benefitting from the design freedom of additive manufacturing.

About The Process

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.

Advantages of Metal 3D Printing

Efficiency
Metal printing defies traditional Design-For-Manufacturing guidelines, so designs that would typically be made in assemblies can be made in a single piece.

Complex Geometries
DMLS and SLM produces parts that cannot be made using traditional manufacturing techniques.

Rapid Turnaround
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.

Production Parts
SLM and DMLS utilizes powdered metals with strong mechanical and dynamic properties, making it perfect for end-use parts.

FAQS

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.
