How does using finer layers affect the FDM printing process?

Using finer layers in the FDM (Fused Deposition Modeling) printing process generally leads to a smoother finish on the printed object. This occurs because thinner layers allow for more details to be captured in the final product. Each layer is laid down with less height, which enables a more refined surface profile that can more closely resemble the intended design without the visible steps or ridges that might occur with thicker layers.

This characteristic is particularly important in applications where aesthetics matter or when additional post-processing, like sanding or painting, is to be minimized. Finer layers also allow for better reproduction of intricate details in complex geometries, contributing to an overall higher quality print.

While finer layers can increase print time, potentially lead to more filament being used due to longer print duration, or have an impact on dimensional accuracy in certain cases, the primary impact is the enhanced surface finish that results from this technique.
