Laser Powder Bed Fusion

LPBF / SLM Standard Particle Size Distribution
10 60 μm

Laser Powder Bed Fusion (LPBF), also known as Selective Laser Melting (SLM), is a metal 3D printing technology that uses a high-powered laser to selectively melt and fuse metal powder particles together to create a solid part. 

In LPBF/SLM, a layer of metal powder is deposited onto a build platform. The high-power laser is then used to selectively melt and fuse the powder particles together, layer by layer, until the part is complete. The process is performed in a controlled atmosphere to prevent oxidation and ensure high-quality part production. 


LPBF/SLM is used in various industries, including aerospace, automotive, medical, and industrial manufacturing. It is particularly useful in applications that require high-strength, high-temperature-resistant parts with complex geometries. LPBF/SLM can also be used for rapid prototyping, tooling, and customization applications. 


Design flexibility

LPBF/SLM enables the creation of complex geometries and intricate designs that would be difficult or impossible to produce with traditional manufacturing methods.

High precision

LPBF/SLM can produce parts with high accuracy and detail, making it useful for creating parts with tight tolerances.

Material flexibility

LPBF/SLM can be used with a wide range of materials, including various metals and alloys, giving designers and engineers more material choices.

Reduced waste

LPBF/SLM only uses the exact amount of material needed to produce a part, reducing waste and saving on material costs.

Metal powders are widely used in various industries, including additive manufacturing, metallurgy, and coatings. The particle size distribution (PSD) of metal powders plays a crucial role in determining the final properties of the end product.
Different metal powder technologies are available with varying PSDs to cater to specific applications.
