Quick Cite

Paragraph starter

The application of additive manufacturing (AM) is significantly influenced by the inherent complexities of its processes, leading to uncertainties in final part quality and mechanical properties. As highlighted by Bikas et al. (2015), current modelling approaches often fall short in accurately predicting these outcomes due to phenomena like melting, solidification, and heat transfer. This necessitates the development and utilization of advanced simulation techniques to bridge the gap between digital design and physical realization, enabling better process control and ensuring design intent is met.
