Mechanical Parameters of PA12 Printouts Obtained in the Uniaxial Tensile Test

Angle (°)	Tensile test
	TS (MPa)	ET (MPa)	EaB (%)
0	42.5 ± 3.1a	864 ± 72b	13.1 ± 2.3a
30	28.1 ± 8.4	690 ± 143	6.7 ± 1.6
45	16.0 ± 2.3	613 ± 27	2.7 ± 0.3
60	25.6 ± 8.9	694 ± 32	8.4 ± 5.7
90	17.1 ± 10.0	426 ± 150	6.0 ± 3.4

Values are presented as means ± SD. Differences between the analyzed printout orientations were examined by using the Friedman test (Dunn post hoc).

^a Statistical significance between 0° and 45°.

^b Statistical significance between 0° and 90°.

EaB, elongation at break; E_T, tensile Young's modulus; TS, tensile strength.
