From Prototyping to Production Using Laser Powder Bed Fusion

The ultimate in speed and precision for metal 3D printing, Metal Laser Sintering — which includes Direct Metal Laser Sintering (DMLS), also known as SLM (Selective Laser Melting) — additively manufactures 99 percent dense metal prototypes and end-use parts.

Producing fine featured parts with the strength and durability comparable to forged parts, the Metal Laser Sintering process is ideal for functional components requiring fast lead times and a design freedom that don't exist with traditional machining.

Metal Laser Powder Bed Fusion (LPBF) is an additive manufacturing process where a high-powered laser selectively fuses fine metal powder layer by layer to build a 3D part. The laser melts the powder according to a digital design, creating complex and highly precise metal components. After each layer is fused, the powder bed lowers, and a new layer of powder is spread for the next layer of the build.

Materials

Select From a Range of Materials

Name

Description

Aluminum - AlSi10Mg

Ideal for components requiring a combination of lightweight, complex geometries with good thermal properties

Copper Alloy - CuCrZr

Cu-based alloys cover a much wider range of applications than most other alloys due to their functional properties. Typical applications include heat exchangers, electrical and are widely used in bearings

Nickel Alloy - Inconel 625

Non-magnetic, corrosion and oxidation resistant, nickel-base superalloy. Outstanding strength and toughness in the temperature range cryogenic to 2000°F (1093°C)

Stainless Steel 17-4PH

Martensitic precipitation/age-hardening stainless steel offering high strength and hardness, along with excellent corrosion resistance, up to 600°F (316°C)

Stainless Steel 316L

Low carbon, non-magnetic, austenitic stainless steel that exhibits moderate to good strength, good fracture toughness, and has generally good corrosion resistance, especially intergranular corrosion
