3D Systems LaserForm® 17-4PH (B) Stainless Steel Materials Product Information -:- For detailed product information, please contact sales. -: # **3D Systems LaserForm® 17-4PH (B) Stainless Steel** ## **Product Overview** 3D Systems LaserForm® 17-4PH (B) is a premium metal powder material specifically engineered for additive manufacturing using Direct Metal Printing (DMP) and Laser Powder Bed Fusion (LPBF) technologies. This material is based on the widely recognized precipitation-hardening stainless steel UNS S17400 (17-4 PH), optimized for 3D printing to produce fully dense, high-strength components with excellent corrosion resistance and mechanical properties comparable to traditionally manufactured 17-4PH stainless steel. The "(B)" designation indicates a specific powder formulation optimized for build reliability and surface finish. ## **Technology Platform Compatibility** - **Primary Process:** Direct Metal Printing (DMP) / Laser Powder Bed Fusion (LPBF) -
