SLS (Selective Laser Sintering) can be utilized to process micron-scale stainless steel powders (such as 316L and 304), falling under the category of "indirect metal 3D printing." This process involves using a laser to sinter metal powder, thereby forming a "green body," which subsequently undergoes post-processing—including debinding and high-temperature sintering—to yield dense metal parts. Distinguished by their exceptional properties—such as strong corrosion resistance, superior mechanical performance, excellent biocompatibility, mirror-finish polishability, and high-temperature oxidation resistance—these products are widely applied across the medical, aerospace, and precision manufacturing sectors.
