What advantages does Stainless Steel 316L offer in SLM versus other materials?

Excellent Corrosion Resistance

Stainless Steel 316L provides superior corrosion resistance compared with many other printable materials, especially in chloride-rich, acidic and marine environments. When SLM-processed through 316L stainless steel 3D printing, the alloy achieves a fine microstructure that enhances durability for components used in marine and pharmaceutical applications.

Good Printability and Process Stability

316L has a wide SLM processing window with low susceptibility to hot cracking, enabling stable melt pools and consistent layer bonding. This makes it easier to produce reliable parts with complex features compared to more brittle alloys or high-temperature superalloys.

High Ductility and Fatigue Resistance

SLM printing refines the grain structure of 316L, increasing ductility and fatigue life. This is particularly beneficial for pressure housings, medical components and load-bearing assemblies. Post-processing via CNC machining easily restores precision features and functional surfaces.

Design Flexibility and Complex Geometry

Compared with wrought and cast 316L, SLM enables internal flow channels, lattice structures and near-net shapes that reduce weight and improve performance. These features are key advantages in pharmaceutical and food and high-performance energy systems.
