• fused deposition modelling
• flat
• curved and adaptive slicing

Fused deposition modelling is one of the additive manufacturing techniques in which part quality is often influenced by stair-step effects and internal meso-structures. Adaptive slicing employing slices of varying thicknesses was attempted as a means of overcoming some of these problems, but with limited success, while speed and time of printing often lead to further complications. On the other hand, curved layer deposition is proved to improve surface quality and part strength in specific cases. This research brings both flat and curved layer approaches together through specific algorithms developed and employed combining the two to process given parts. The mixed slicing method is applied successfully to three test cases, practically implemented on a test bed, and proved to be feasible and effective.
