XJet has added 17-4PH stainless steel to its portfolio of materials for metal and ceramic additive manufacturing. The new material, offering high hardness and tensile strength, has been introduced to expand industrial applications across a range of sectors including medical devices and surgical instruments, aerospace and defence, oil and gas filtration, and high-precision tooling and manufacturing.

The 17-4PH solution promises a rapid production process with a new soluble support material, based on XJet’s proprietary NanoParticle Jetting (NPJ) technology. The new support material maximizes the freedom of design and dramatically shortens the automated end-to-end manufacturing process of Metal 3D parts, while further improving NPJ’s leading surface roughness and accuracy.

With XJet’s rapid three-step-process: Print-Wash-Sinter, and the accuracy and smooth surfaces delivered by XJet NPJ technology, post-processing requirements are an absolute minimum, shortening the manufacturing lead time to just weeks.

The material properties of XJet 17-4PH stainless steel—high tensile strength, hardness, fatigue resistance and corrosion resistance—in combination with accuracy to 50 microns with NPJ technology, will unlock new possibilities for innovation and drive new applications.
