Metal 3D-printing with steels and other iron-based materials fit in to a wide range of applications due to the high material strength. From stainless steels to tool steels to quenched and tempered steels, we are sure you’ll find a material that meets the requirements for your application. If not, we can also qualify new materials for you.

Our metal 3D-printing systems, based on the Laser Powder Bed Fusion (LPBF) technology, process a wide variety of metal materials. The iron-based materials can meet any requirement of your components whether in prototyping, tooling, special applications and series production.

With over 40 qualified metal materials, Rosswag Engineering offers a globally unique selection and thus the right material for many iron-based, steel-based and stainless steel 3D printing applications. The classification of the materials in Technology Readiness Level (TRL) shows the maturity of a material from initial qualification to series production.
As a customer, you benefit from our expertise in processing all materials in a holistic process chain with the appropriate process parameters in each case.
