About Stainless Steel

Stainless steel is a sturdy metal material with high tensile strength, good thermal properties and highly resistant to corrosion. The material has been playing a crucial role in multiple industries for over a century. The ability to 3D print in stainless steel will likely expand the potential of this high chromium and low carbon alloy. After all, 3D printing in stainless steel creates parts that are higher in the complexity of design than machined parts, without compromising the material’s excellent material properties. Such achievement is nearly impossible with conventional production technologies.

Stainless steel 3D printed parts are strong, durable and lightweight with a good level of detail. Depending on the chosen stainless steel material, parts can withstand temperatures of up to 800°C. Another advantage of 3D printing in stainless steel is the possibility of creating large objects with fantastic surface quality and resolution. It is with no surprise that this high-performance metal 3D printing material is used for many industrial applications in aerospace, automotive and manufacturing.
