Actual values may vary with build conditions.

Strong tensions due to part geometry may distort parts, potentially leading to greater deviation in values. Values for surface roughness depend on the orientation of the surface; downward-facing surfaces and surfaces with support will be rougher.

These measurement values show the material characteristics with additional stress relief heat treatment. Extra heat treatment steps or aging for even higher mechanical properties may be possible, e.g. for serial-produced parts.
