“Objects printed in 316L stainless steel from fine metallic powder primarily composed of iron (66-70%), enriched with chrome (16-18%), nickel (11-14%), and molybdenum (2-3%). The material provides strong resistance against corrosion and is distinguished for its high ductility. These features make it a great candidate for implementation in several industries, such as the medical field for surgical assistance, endoscopic surgery, or orthopedics; in the aerospace industry for producing mechanical parts; in the automobile industry for corrosion-resistant parts; but also for making watches and jewelry.
316L Stainless Steel printing is very accurate because of the fine coating resolution (30-40 µm) and the laser’s accuracy. Unlike polymer powder sintering, stainless steel printing through DMLS requires adding base structures in order to attach the part to the board and to strengthen distinctive geometries like overhangs. The bases themselves are made from the same powder as the piece and will be taken off afterward.”
Stainless Steel 3D printing is produced by fusion or laser sintering. Two possible technologies exist for this material: DMLS and SLM. We use DMLS (Direct Metal Laser Sintering) technology, a laser sintering technique on a EOS M280 machine to print stainless steel. The laser beam brings the metal powder close to its fusion point layer after layer in order to produce your object.
