Utilisation of lattice discrete particle model for modelling of 3D-printed alloys
Original language description
The paper presents a novel and detailed numerical approach for modelling 3D-printed titanium alloys, particularly in the context of intraosseous implant parts. The research is motivated by the need to comprehend the effects of manufacturing imperfections, such as porosity, which significantly influence the mechanical properties of these alloys. Using the Lattice Discrete Particle Model (LDPM), the study simulates the material's behaviour at a mesoscopic level, focusing on how imperfections that arise during the 3D printing process impact the material's performance under different loading conditions. The LDPM approach, which considers particle size and distribution, crucial factors in understanding the material's behaviour, was used to validate the model with experimental data from three-point bending tests on specimens with varying thicknesses. The findings underscore the practical implications of the research, revealing that thinner specimens, which are closer to the limits of 3D printing capabilities, tend to have higher porosity and, thus, lower ultimate strength. This model is crucial for developing patient-specific implants by predicting material performance in real-world applications. The paper emphasizes the importance of accurate numerical modelling in enhancing the design and functionality of 3D-printed materials, particularly in biomedical applications where implant success is critical. By integrating experimental data with advanced simulation techniques, the research provides a valuable tool for optimizing the design and manufacturing process of 3D-printed titanium alloys used in medical implants.
