to water molecule evaporation. As this peak was not than the original PVA filaments, and (ii) water molecules
present for samples Filament 1D and Filament 3D, two may play an important role in the crystallinity of PVA.
major conclusions may be drawn: (i) the 3D-printed Water molecules may act as plasticizers for PVA chains,
PVA channels are more susceptible to water absorption hindering the crystallization process. During the thermal
