Over the last four decades, additive manufacturing has established itself as a cost-effective, on-demand method for fabricating geometrically complicated structures. Tissue engineering has incited a lot of interest in recent years due to its enormous potential for repairing or replacing damaged tissues. In terms of mechanical and biological properties, creating scaffolds for tissue engineering remains a challenge. The current review concentrates on scaffold manufacturing of PLA nanofibers (NF)-based scaffolds as it is bioresorbable & biocompatible with human body, since they are one of the three most significant components in tissue engineering, along with seed cells, growth regulators, and scaffolds that could be helpful for novice researchers. In addition, the technological aspects of the electrospinning technique are employed to manufacture PLA NF in the case study, and fused filament fabrication (FFF) technology is used to build tensile specimens of PLA/PLA-NF composites. The results of the case study have been supported by tensile testing, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM).
