| Abstract Scope |
Additive manufacturing has emerged as a promising tool for fabricating complex, patient-specific scaffolds for bone tissue engineering. Biodegradable materials are increasingly used because they progressively degrade while new tissue forms, ideally matching bone regeneration and enabling gradual load transfer.
Polymer-metal composites produced via fused filament fabrication offer a promising strategy to tailor mechanical and degradation behaviour, where continuous metallic reinforcements enhance the stiffness and strength of biodegradable polymers while influencing degradation kinetics. However, biodegradable 3D-printed wire-reinforced scaffolds for bone regeneration remain underexplored.
The aim of this work is to manufacture and characterise bioabsorbable wire-reinforced polymers for bone regeneration. Polylactic acid scaffolds reinforced with magnesium wires were fabricated using a customised 3D printing system. Mechanical and degradation studies were conducted to evaluate the scaffold's ability to maintain structural integrity during degradation while supporting native tissue regeneration. Finally, biological characterisation was carried out through in vitro and in vivo testing. |
