Core Technology: Dominated by Powder Bed Fusion, Simultaneous Improvement of Precision and Efficiency

As a core branch of metal additive manufacturing, stainless steel 3D printing is currently dominated by powder bed fusion technology. Among them, Selective Laser Melting (SLM) and Direct Metal Laser Sintering (DMLS) account for 68% of the market share, achieving an ultra-high dimensional precision of ±0.05mm. Its core principle is to spread spherical stainless steel powder of 10-60 microns layer by layer, and selectively scan with a high-power laser to melt and solidify the powder for layer-by-layer superposition molding, enabling the manufacturing of complex structures without traditional molds. Among mainstream printing materials, 316L stainless steel accounts for 52% and 17-4PH accounts for 28%. With excellent fluidity and molding performance, they are widely adapted to the needs of various industries. Meanwhile, the application of multi-laser systems has increased printing speed by 40% compared with five years ago, and powder reuse efficiency reaches 90%-96%, greatly reducing material waste and promoting the technological upgrade towards high efficiency and low carbon.

   Diversified Applications: Penetrating Multiple Fields, Unlocking New Manufacturing Possibilities

With the advantages of high strength, corrosion resistance and customizability, stainless steel 3D printing has deeply penetrated aerospace, medical, automotive and other key fields, becoming an important support for the upgrading of high-end manufacturing. In the aerospace field, 72% of American aerospace manufacturers have integrated it into production for manufacturing aircraft structural parts and engine components, greatly reducing equipment weight and improving reliability. In the medical field, its good biocompatibility makes it an ideal manufacturing method for artificial joints and dental implants, enabling personalized customization according to patients' physical signs. The automotive industry uses it to realize small-batch customized parts and rapid mold development, shortening the traditional mold manufacturing cycle from several months to 1-2 weeks, and reducing the manufacturing cost of small-batch parts by 40%-60% compared with traditional processes. In addition, it also shows irreplaceable application value in energy, mold manufacturing and other fields.
