The significant critical barrier in the ascension of fused deposition modeling (FDM) into a scalable

technology is the lack of defined quality benchmarks for validating filament performance. To avoid this

issue, we aimed to create a comprehensive quantitative approach providing a road map to evaluate the

fabricated filament for successful FDM 3D printing. Materials & methods: A detailed in vitro physicotechnological

analysis including axial as well as oscillatory stress tests were performed to validate the

melt-extruded filament. Results & conclusion: The results from the above noted tests as well asmicroscopic

examinations suggested toward the superiority of 6.5% plasticizer-loaded drug-polymer filaments in

terms of mechanical prerequisites like feedability, extrudability and printability, as well as complete

molecular homogenization.
