How it works:
A high-power laser scans across a bed of polymer powder, melting only the areas that make up the part. Each new layer of powder is spread evenly, while the previous layer solidifies. As shown in the diagram, un-melted powder surrounds the part, acting as a natural support structure throughout the build.
Where it’s used:
SLS is widely used in aerospace, automotive, and industrial design for producing complex housings, brackets, and connectors. It’s favored for functional prototypes, end-use parts, and custom components with mechanical loads. Its support-free printing and strong material properties also make it a great choice for small-batch production runs.
