Abstract
The printing approach of curved layer fused deposition modelling (CLFDM) is gaining popularity for its superior part properties when compared to those obtained from conventional FDM approach. Past studies reveal that the study of effects of fill gap (FG) on these two approaches (CLFDM and conventional FDM) with different printing directions needs a thorough numerical investigation. Therefore, the present work introduces numerical modelling based on genetic programming for investigating the flexural strength of the fabricated parts from FDM and CLFDM. It was found that the GP-based flexural strength models are able to generalize both processes satisfactorily. It was also noticed that the GP-based flexural strength models for horizontal printed parts predict with higher accuracy than those for parts printed in vertical directions. Experiments were performed to validate the GP models.
