Table 3.

The stress-strain properties used for grading purposes are summarized for specimens manufactured via an XY laser scan strategy. The average and standard deviation values are provided (sample size is N=12, except for XY-30° where N=9), which take into consideration specimens from different manufactured blocks. Refer to Section 2.3 for information about the specimen notation used here. The seven stress-strain properties are Young’s modulus (E), the 0.2% offset yield strength converted into true stress (σ_Y), the true stress at a true strain of 0.05 (σ_0.05), the true stress at a true strain of 0.10 (σ_0.10), the true stress at a true strain of 0.20 (σ_0.20), the ultimate tensile strength converted into true stress (σ_UTS), and the true strain at the ultimate tensile strength (σ_UTS).
