Abstract

In this study, the use of extrusion-based 3D printing for the fabrication of a personalized drug delivery Polylactic acid (PLA) – Aspirin (ASA) mesh for bone tissue engineering is examined. Hot Melt extrusion (HME) significantly improves the solubility and bioavailability of poorly soluble drugs, while 3D printing enables personalised drug dosage, geometry, and mechanical properties. PLA is biodegradable and has properties that allow cellular attachment and tissue regeneration; while ASA is a substance that promotes bone regeneration and decreases associated infections. Surgical meshes for bone tissue repair and drug delivery are created through Hot Melt Extrusion (HME) and Fused Deposition Modelling (FDM) 3D printing. This work investigates the production of PLA-ASA filament using a low-cost single-screw filament extruder, the effects of 3D printing temperature on ASA stability using Raman Spectroscopy, and the flexibility and integrity of 3D printed PLA-ASA mesh.
