What is a key method to achieve a smooth surface finish in FDM prints?

Optimizing print settings is crucial for achieving a smooth surface finish in Fused Deposition Modelling (FDM) prints. The print settings include parameters such as layer height, print speed, temperature, and infill density. By carefully adjusting these settings—such as using a finer layer height or adjusting the cooling settings—print quality can be greatly enhanced, resulting in smoother surfaces and fewer visible layer lines.

When the layer height is reduced, for instance, each individual layer is thinner, leading to a more refined finish. Additionally, optimizing the print speed can ensure that the filament adheres better and flows more consistently, which also contributes to a smoother appearance. Proper temperature settings can help with extrusion consistency, influencing the final surface quality as well. Therefore, a holistic approach to optimizing all these settings plays a vital role in achieving an aesthetically pleasing and smooth finish on FDM prints.
