316L Stainless Steel
316L stainless steel is one of the most commonly used stainless steel grades in 3D printing. Thanks to the extremely high temperature gradient and extremely fast solidification rate during the printing process, the material's mechanical properties after molding are better than traditional castings (although some printers also support printing in 17-4 PH stainless steel). 316L is a metal with strong mechanical properties. The printed surface is usually rough and has pitting (melt pool marks). The material can provide a variety of polished or matte post-processing effects and is widely used in jewelry, functional parts, small sculptures and other fields.
