Paragraph starter
This research highlights the critical role of surface roughness in layer-based additive manufacturing, demonstrating that predictive modelling and controlled post-processing are essential for achieving desired product quality. The development of theoretical models, validated experimentally, allows for a better understanding of surface topography, while techniques like acetone vapour smoothing can significantly improve surface finish, with optimal parameters dependent on geometric complexity. This underscores the need for designers to integrate surface quality considerations into their design process for AM parts.
