Over the years, articular cartilage damage has impacted living standards world wide. Since each of the traditional therapeutic approaches has limitations, tissue engineering-based approaches have been recruited to provide a feasible solution. This study aimed to develop a novel nanocomposite 3D printed scaffold via a polymeric matrix accompanied with alginate nanoparticles and functionalized multi-walled carbon nanotubes (MWCNTs) to investigate its potential appropriateness for cartilage tissue engineering application. In this way, 3D printed constructs was developed by an extrusion-based printing method using the innovative nanocomposite inks consisting of PCL (polycaprolactone, P 35% w/v) and PLGA (poly (lactic-co-glycolic acid, P 15% w/v) incorporated with alginate nanoparticles (40 and 45% w/v), as a filler, and modified with or without MWCNTs (0.05 and 0.1% w/v), as a composite reinforcement. Next, the characterization of scaffold features was investigated. Results revealed that 3D printed scaffold containing PP/alginate45% with MWCNT0.05 (PPA45M0.05) had significant improvements in porosity (74.29%±7.33), water uptake, absorbance, cell attachment, hydrophilicity (64.15 ± 1.87), the compression modulus(0.2174MPa), and the degradation rate. In addition, the interaction within the whole constituents was validated by the spectra of ATR-FTIR. Due to the proper biodegradability, biocompatibility, and mechanical aspects, the PPA45M0.05 scaffolds would be a potential construct for cartilage tissue engineering.
