Paragraph starter
The 'staircase effect' is a common artifact in additive manufacturing due to planar layer deposition. Research by Etienne et al. (2019) demonstrates that by deforming the 3D model to optimize for curved layer deposition in FFF, this effect can be significantly reduced, leading to improved surface quality and aesthetics. This suggests that for design projects prioritizing visual finish, exploring advanced slicing techniques beyond standard planar methods is a valuable consideration.
