Negative Strain Scaling Factor

The additive Print result requires a negative strain scaling factor for calibration, but this is not possible. What to do?

There are 2 potential causes for the need for a negative strain scaling factor. In some alloys, there is a phase change that swells the part, or a user may improperly build the part with beam offsets that overcompensate for shrinkage. If it was maraging steel, then a negative strain scaling factor is physically realistic. For 316L, the user needs to follow the recommended approach for building the part. A negative strain scaling factor will be available in 2019 R3 for alloys that swell.
