This work establishes a novel, systematic methodological framework that bridges processing parameter quality (filament purity and infill density) with nondestructive macroscopic defect prescreening. By differentiating structural manufacturing artifacts from true material behavior prior to mechanical testing, this approach ensures reliable quality assurance for functional, biobased medical parts. The material was processed into a high-quality filament using a 3devo filament maker, followed by the fabrication of Type 5A dogbone specimens via Fused Deposition Modeling (FDM). To investigate the influence of internal architecture on material quality, two distinct infill densities were applied: 50% and 100%. Post-printing, a systematic macroscopic analysis was conducted to assess surface morphology, filament purity, and overall specimen consistency. The results provide a critical evaluation of the printing quality and the purity of the extruded filament. This work establishes a robust methodological framework for future destructive testing, ensuring that macroscopic defects are accounted for prior to mechanical performance characterization. These findings are essential for optimizing the production of reliable, biobased functional parts in medical applications.
