Table 4.
The stress-strain properties used for grading purposes are summarized for specimens manufactured via an X-only laser scan strategy. The average and standard deviation values are provided (sample size is N=12), which take into consideration specimens from different manufactured blocks. Refer to Section 2.3 for information about the specimen notation used here. Some tests were invalid (INV) due to failure occurring outside of the gauge length.
