Fig. 7 . Yield Strength (UTS) for 0 group ( as-built condition). Min value for horizontally and vertically fabricated specimens, as per EOS reference (Table 3). Horizontally fabricated maximum uncertainty as per EOS reference (Table 5).

Fig. 8 . Fracture elongation (El%) for 0 group ( as-built condition). Min value for horizontally and vertically fabricated specimens, as per EOS reference (Table 5).

A1 group (H900 STANDARD) Average measured UTS for vertical specimens (UTS v =1621±18 MPa) and horizontal (UTS h =1494±11 MPa) as well as average measured YS for vertical specimens (YS v =1503±16 MPa) and horizontal (YS h =1374±14 MPa) are equivalent within the error bar (full error bar=2σ ( - σ; + σ; symmetric), σ being the standard deviation, calculated for each group of samples). Average measured ROA% for vertical specimens (ROA% v =50,0±1,8) and horizontal (ROA% h =50,6±3,8) are perfectly equivalent within the error bar (full error bar=2σ ( - σ; + σ; symmetric), σ being the standard deviation, calculated for each group of samples). Average measured El% for vertical specimens (El% v =14,5±0,6) and horizontal (El% h =21,1±0,9 MPa) shows a different ductile behavior of samples in the two building directions (full error bar=2σ (- σ; + σ; symmetric), σ being the standard deviation, calculated for each group of samples) .
