Abstract Scope |
Additive manufacturing (AM) of bioresorbable magnesium (Mg) alloys has gained significant interest in the biomedical field due to their biocompatibility and patient-specific design. However, due to the safety concerns related to common metal AM techniques such as Laser Powder Bed Fusion (L-PBF), low-temperature AM methods such as material extrusion offer significant potential. Understanding the shrinkage and distortion occurring during thermal debinding and sintering is essential for optimising low-temperature AM processes. This study investigated the thermal debinding and sintering of Mg alloys both computationally and experimentally. Numerical simulations were performed to control polymer residue during debinding and to predict the shrinkage and distortion of Mg parts during sintering. To ensure accuracy, extensive experimental validation was conducted, gathering empirical data to refine the simulations. This iterative approach enhanced the model's predictive capabilities. Our results enable the effective optimisation of low-temperature AM processes for Mg alloys, improving their application potential in biomedical implants. |
