3D Printing With Aluminum

Aluminum’s material characteristics make it ideal for many applications in many industries, for example aerospace and automotive.

EOS’ aluminum family of powders encompasses the AlSi10Mg and AlF357 alloys which are typical aluminum-silicon casting alloys. These powders are designed and tested for use on EOS’ metal systems.

All EOS aluminum 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 system 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.
