316L stainless steel is called UNS S31603 or EN 1.4404. It is a stainless steel material containing molybdenum. Its main components include iron, chromium, nickel, molybdenum and a small amount of manganese, silicon, carbon and other elements. Its chromium content is about 16%-18%, nickel content is between 10%-14%, and molybdenum content is about 2%. It is precisely because of the presence of molybdenum that 316L stainless steel has excellent resistance to pitting, crevice corrosion and chloride ion stress corrosion cracking, and also enhances its resistance to oxidizing and reducing media in high temperature environments.

In 3D printing technology, especially in metal additive manufacturing technologies such as selective laser melting (SLM) and electron beam melting (EBM), stainless steel 316L has become an ideal choice. Due to its excellent forming performance and mechanical properties, 316L stainless steel can be used to print various complex structure parts and is widely used in aerospace, medical equipment, petrochemical, food processing and other industries. Especially in the biomedical field, 316L is used to print human implants, such as hip joints, dental restorations, etc. Stainless steel 316L, as a representative austenitic stainless steel, has emerged in the field of 3D printing materials in recent years, and has attracted widespread attention with its excellent corrosion resistance, high strength and good biocompatibility.

1. Corrosion resistance: 316L stainless steel has high corrosion resistance, especially for seawater, organic acids, alkalis, salts and many inorganic compounds, which enables the printed products to maintain a good service life in a variety of harsh environments.

2. High strength and heat resistance: After 3D printing, although the microstructure of 316L stainless steel may be different, it can still maintain high strength and hardness as a whole, and has good high temperature strength and lasting strength, which is suitable for use in high temperature environments.

3. Biocompatibility: 316L stainless steel will not cause obvious rejection reactions when implanted in the human body for a long time, and it is not easy to cause allergies, so it is widely used in the field of medical implants.

4. Excellent printing performance: 316L stainless steel powder is easy to melt, and the microstructure after cooling and solidification is uniform and dense, which is conducive to ensuring the mechanical properties and dimensional accuracy of 3D printed parts.

5. Green and environmentally friendly: Stainless steel 316L generates less waste during production and use, which is in line with the concept of modern industry pursuing sustainable development
