XJet introduces new 17-4PH stainless steel solution

XJet has expanded its material portfolio for metal and ceramic additive manufacturing with the introduction of 17-4PH stainless steel, leveraging their NanoParticle Jetting (NPJ) technology. This material, known for its high hardness and tensile strength, is now available for industrial applications in sectors such as medical devices, aerospace, defense, oil and gas filtration, and high-precision tooling.

The 17-4PH stainless steel joins XJet’s existing offerings, which include ceramics and 316L stainless steel. One of the key innovations accompanying this new material is a novel soluble support material that enhances design flexibility and reduces the overall manufacturing time. XJet’s proprietary metal material jetting technology facilitates this advancement, which significantly improves surface roughness and accuracy of the produced parts.

Key Advantages:

  1. Time and Labor Savings: XJet technology reduces post-processing requirements dramatically. The soluble support material allows for removal in as little as six hours, which is considerably faster compared to other additive manufacturing (AM) processes.
  2. Rapid Production Process: The new 17-4PH solution integrates into XJet’s three-step process (Print-Wash-Sinter), minimizing post-processing needs and shortening the lead time to just weeks.
  3. Complex Inner Cavities: XJet’s technology can create intricate internal geometries that are difficult or impossible to achieve with other AM methods. This capability is particularly beneficial for pre-assembly in medical device manufacturing, offering true design freedom and reducing assembly complexity.
  4. Enhanced Design Freedom: The ability to produce complex parts without extensive post-processing and the support material’s quick removal time supports more innovative and efficient designs across various applications.

System and Applications:

  • XJet Carmel 1400M System: This system supports both 316L and 17-4PH stainless steel, providing users with versatile options for different industrial applications.
  • Medical and Aerospace: The new material and technology are especially advantageous for producing medical devices and surgical instruments, where precision and complex design are critical. The aerospace sector also benefits from these innovations, where durable and precisely engineered components are essential.

Industry Implications:

The introduction of 17-4PH stainless steel by XJet broadens the potential applications of NPJ technology, enabling manufacturers to produce high-precision parts more efficiently and cost-effectively. This development is set to accelerate the adoption of metal additive manufacturing in high-demand industries, providing solutions that were previously unattainable with traditional manufacturing methods.
