This study introduces a novel approach to 4D printing of biocompatible Poly lactic acid (PLA)/poly methyl methacrylate (PMMA) blends using Artificial Neural Network (ANN) and Response Surface Methodology (RSM). The goal is optimize PMMA content, nozzle temperature, raster angle, speed enhance shape memory properties mechanical strength. materials, PLA PMMA, are melt-blended printed pellet-based 3D printer. Differential Scanning Calorimetry (DSC) Dynamic Mechanical Thermal Analysis (DMTA) assess the thermal behavior compatibility blends. ANN model demonstrates superior prediction accuracy generalization capability compared RSM model. Experimental results show recovery ratio 100% an ultimate tensile strength 65.2 MPa, significantly higher than pure PLA. A bio-screw, with optimized parameters, excellent behavior, suitable for biomedical applications such as orthopaedics dental implants. research presents innovative method PLA/PMMA blends, highlighting their potential in creating advanced, high-performance materials medical use.
