The ExOne Company, a global provider of binder jetting 3D printing systems, services and materials, has today released a new metal feedstock to help broaden the company’s potential customer base and applications.
Adding to an existing range high grade metal alloys, 17-4PH stainless steel metal powder has high hardness and corrosion resistance properties. It is typically used in aerospace, petroleum and chemical industries, reinforcing ExOne’s commitment to high-value engineering customers.

17-4PH is composed, approximately, of 15% chromium and 3% nickel, 5% copper and lesser amounts of other minerals such as manganese and silicon. As with most structural alloys, including aluminium, nickel and titanium, parts made from 17-4PH are heat-treated to increase hardness. Treatment provided, the metal is then capable of withstanding temperatures up to 600 °F (316 °C) which is essential for structural stability.
ExOne has made the material specially for 3D printing using its proprietary binder jetting technology. In this process, parts are solidified from a metal powder by the addition of a liquid binder. Each layer is individually cured, giving the technique an advantage...
