To improve the interfacial mechanical properties by using an alternating print strategy, the interface can be enhanced by the formation of PLLA/PDLA stereocomplex crystals across the interface. By analyzing the 2D-WAXS patterns during and after performing a T-peel test on a single interface and using the measured force to calculate the fracture energy, a direct link between structure and interfacial properties can be made. Our objective is to study the influence of the stereocomplex crystal on the fracture energy, and whether the adhesion between layers can be improved by applying an alternative printing strategy that alternates the material.
