What is SLM 3D Printing?
SLM (Selective Laser Melting) is a powder bed fusion technology. In this process, a high-energy laser beam fully melts fine layers of metal powder, forming dense and high-strength metal parts. The mechanical performance of SLM parts often matches that of forged components and can even surpass traditional processes in certain applications.
How Does SLM 3D Printing Work?
-
A thin layer of metal powder is spread evenly across the build platform.
-
A laser beam selectively melts the powder according to the CAD model path.
-
Each layer is built up and fused with the previous one.
-
The process continues until the dense 3D metal part is formed.
-
After printing, post-processing steps such as support removal, heat treatment, and surface finishing are applied.
Key Features of SLM 3D Printed Parts
