Table 2. Results of the tensile test in the bio-3D printed structures and the native esophagus of rats.

	Thickness (mm)	Maximum load tensile elongation (mm)	Tensile strength (N)
Group 1 (n = 3)	0.64±0.05	1.92±0.18	0.29±0.081*
Group 2 (n = 3)	0.63±0.24	2.11±0.34	0.31±0.011*
Group 3 (n = 3)	0.8±0.09	1.24±0.62	0.19±0.011
Group 4 (n = 3)	0.63±0.18	2.02±0.27	0.12±0.043
NE (n = 3)	0.59±0.26	5.27±0.43	0.46±0.068

Values are expressed as the mean ± standard deviation

* The structures in groups 1 and 2 exhibited significantly greater tensile strength than those in group 4 (P<0.05)
