In this step, you assign a material to each geometry body, considering the following guidelines:
All bodies comprising the build (part and supports) must be the same material.
The base plate can be a different material.
If you are modeling powder, use the same material as the build.
Non-build components can be different materials.
Procedural Steps
When you select a geometry entity in the project tree, the Details view lists all the settings associated with that body.
In the project tree under Model, expand the Geometry object to see its child objects below it. Select the geometric entity that is the build geometry and, in Details view, change the Assignment (under Material) to be the AM material that you want to use, either one of the Ansys predefined samples, or a custom material you defined in Engineering Data. When you assign a material to the build, the child objects below it (the part and supports) are also assigned that same material.
Select the entity that is the base plate body and change its material Assignment, as desired.
