Abstract Scope Polymeric materials are being explored for their applications in biomedical sector owing to their biocompatibility and biodegradability. Recently, polyetherimide (PEI) has emerged as a potential biomaterial. Although several researchers are exploring PEEK for orthopedic applications, PEI material is still under-explored. Additionally, additive manufacturing techniques provide an opportunity to fabricate patient-specific porous structures required for bone tissue scaffolds. Several studies reported experimental investigations on additively manufactured scaffolds; however, utilization of numerical simulation tools for performance evaluation of these processes is still in infancy. Therefore, this study presents the performance assessment of 3D printed PEI-based porous scaffolds fabricated through the fused filament fabrication process. Numerical simulations of the FFF process were performed to evaluate the dimensional variations and process-induced defects. The results from these simulations will assist in identifying the hotspot regions for design improvements and investigate the mechanical properties of 3D printed porous scaffolds numerically.
