316L, a low-carbon alloy of stainless steel also known as 1.4404, is highly corrosion-resistant and offers excellent strength. 3D-printed stainless steel has high ductility and good thermal properties. Stainless steel can be used for food-safe applications, machine components and production tools. Other applications include ductwork, durable prototypes, spare parts, medical instruments and wearables.

How Does Metal 3D Printing Work?

Metal 3D Printing is a laser-based technology that uses powdered metals. Similar to Laser Sintering, a high-powered laser selectively binds together particles on the powder bed while the machine distributes even layers of metallic powder. Support structures are automatically generated and built simultaneously in the same material, and are later manually removed. Once complete, the part undergoes heat treatment.
