Prashanth Ravi brings additional data to light in a recently published study, ‘ Understanding the relationship between slicing and measured fill density in material extrusion 3D printing towards precision porosity constructs for biomedical and pharmaceutical applications .’

 .

Helping us to understand more about the effects of slicing and porosity in biomedical applications, Ravi explores basic yet crucial printing parameters like fill density in FDM (FFF, Material Extrusion). While such topics have been the center of numerous research studies from use with 3D printed medical models, to materials like PLA , and new techniques and settings, in this study Ravi investigated discrepancies and deviations regarding the measured and slicing fill density for smaller-sized prints with low fill and high porosity.
