EOS Maraging Steel (18Ni300 · MS1)
About The Materials
Parts show very good mechanical properties being easily heat treatable using a simple thermal age-hardening process to obtain excellent hardness and strength.
Materials Documentations
Tool Steel for Additive Manufacturing
Tool steel’s material characteristics make it ideal for a wide range of tooling applications across all industries.
The tool steel family of powders encompasses the MS1, 1.2709, CX and CM55 alloys. All these powders are designed and tested for use on EOS’ metal systems.
All EOS 3D printing tool steel powders are shipped with an inspection certificate (according to EN 10204, Type 3.1) showing the results of the extensive QA testing not only of the powder itself but also of test parts built on a dedicated 3D printer with a dedicated process.
EOS also offers a wide range of validated processes for each of the above materials. These offer the optimal combination of parameters (e.g. laser power, layer thickness, etc.) in order to ensure that the properties of the 3D printed part are consistently achieved.
