ProMateria GmbH (GMH GRUPPE)

ProMateria is an end‑to‑end industrial additive manufacturing partner that supports customers from material selection and design optimization through to the delivery of ready‑to‑install components. The company combines in‑house metal powder production with sinter‑based AM, enabling design freedom, mass customization, and high cost efficiency.

Its key differentiator is the use of high‑nitrogen steel, a material known for exceptional corrosion resistance, strength, hardness, and biocompatibility. With this alloy, ProMateria produces lighter, more durable, and highly polishable components that outperform parts made from conventional steel grades.
