Press Release

Leuven, Belgium – 8 June 2016. Materialise NV (NASDAQ: MTLS) has now introduced Stainless Steel, also known as 316L and 1.4404, into its Metal 3D Printing portfolio. The new material joins an ever-expanding repertoire of over 30 materials, including titanium and aluminum, at one of Europe's largest factories for 3D Printing.

The announcement follows the opening of Materialise's new Metal 3D Printing Factory in Bremen, Germany, in April 2016. In addition to the established benefits of Additive Manufacturing for unrestricted design, metal additive manufacturing in particular allows for the production of lightweight and complex designs that make efficient use of high-value materials. By expanding its material portfolio, Materialise aims to better serve its industrial customers in the sectors of manufacturing, automotive, and aeronautics.

With the introduction of Stainless Steel, Materialise brings the strength and flexibility of metal additive manufacturing to applications in machine-building and tool-making. Stainless Steel is also widely used for food-safe applications and medical instruments, and is well-suited to the production of durable prototypes, spare parts, ductwork, and production tools.

316L is a low-carbon alloy of Stainless Steel, with corrosion-resistant properties and excellent strength. This material is an ideal choice for applications that can take advantage of its durability, high ductility and good thermal properties.
