Physical characterization of the 3D-printed PCL and PLATMC, in terms of wettability and mechanical properties. a micrographs for contact angle measurement (top), and macroscopic images for the hydrophilic behavior using a drop of dye/water (bottom raw). b and c charts for the contact angle measurements of PLATMC versus PCL in 3D-printed (b) and casted sheet forms (c), respectively. d load force vs time curves, with inset photographs for the printed samples prepared according to ASTM-D638. e and f column charts of the mean ultimate tensile stress, and Young’s modulus, respectively. Note the significant higher wettability and tensile strength of PLATMC. * p > 0.0332, **** p < 0.0001
