Enhancing bone repair ability of 3D-printed PLLA scaffolds via N-methyl-2-pyrrolidone etching

Key Points

• The etching process significantly enhances the bone repair capability of the PLLA scaffolds.
• N-methyl-2-pyrrolidone was used in the etching process to modify the scaffolds effectively.
• 3D-printed scaffolds provided a supportive structure for enhanced bone regeneration outcomes.
• The findings underscore the potential of advanced biomaterials to improve surgical outcomes.
