What is the primary purpose of layer resolution in FDM printing?

Layer resolution in Fused Deposition Modelling (FDM) printing primarily refers to the thickness of each layer that is deposited during the printing process. This thickness directly affects the level of detail that can be achieved in the final printed model. When the layer resolution is set to a smaller thickness, the printer can create finer details and smoother surfaces, resulting in a higher-quality finish. Conversely, thicker layers may lead to a more rugged appearance with less intricate detail.

While layer resolution can have secondary effects on factors like strength and printing speed, its primary role is to dictate how well the printer can reproduce intricate designs. Therefore, understanding layer resolution is crucial for achieving the desired detail in a print, making it a vital consideration in FDM printing.
