Elastic deformation behavior is modulated by biomaterial composition but not by printing itself. (a) Representative portion of stress/strain data from unconfined compression. (b) Young's moduli of hydrogels prepared with 10%, 15%, 20% GelMA and 0.25%, 0.5% LAP (****p ≤ 0.0001). There was no significant difference between hydrogels prepared with 0.25% and 0.5% LAP. (c) Young's moduli of printed and molded GelMA cylinders (15% GelMA, 0.25% LAP). Note that elastic moduli in (b) were measured in uniaxial compression with a strain rate of 10%/min, while elastic moduli in (c) were measured using a strain rate of 16.5%/min.
