Study of the bio-nanofluid heat transfer rate and thermo-physical properties of fused deposition modeling of bone scaffold dip-coated by polyvinyl alcohol/nano-diopside

Since the introduction of 3D printing to biomedical fields, numerous advancements have been achieved in tissue engineering due to the advantages it offers. However, 3D-printed polymeric scaffolds may lack certain properties, impacting their functionality and success, such as bioactivity and cell affinity. In this study, the dip coating method was employed to enhance the biological and mechanical properties of 3D-printed polylactic acid (PLA) scaffolds using fused deposition modeling (FDM) technology. Specifically, the scaffolds were dip-coated with a polyvinyl alcohol (PVA)/nano-diopside solution. The thermal features of the 3D-printed scaffolds were analyzed using the differential scanning calorimetry method, revealing a calculated crystallinity of about 13
