Stainless steel is a 3D printing material that is known for its strength, corrosion resistance, and durability. It is a metal alloy that is composed of iron, carbon, and various other elements such as nickel, chromium, and molybdenum.
Stainless steel is compatible with several 3D printing technologies, including binder jetting and direct energy deposition (DED). In binder jetting, a binder material is used to bind the stainless steel powder together layer by layer to create the final part. In DED, a laser or electron beam is used to melt and fuse the stainless steel powder together to create the final part.
Stainless steel 3D printing produces parts with excellent mechanical properties, such as strength, ductility, and toughness. It also has good thermal and electrical conductivity, making it suitable for a wide range of applications such as aerospace, automotive, and medical devices.
When 3D printing with stainless steel, it is important to take into account the shrinkage that can occur during the sintering or melting process. Proper support structures may also be needed to ensure good part quality.
