How many layers does the process of FDM typically involve?

In Fused Deposition Modeling (FDM), the process typically involves several layers, as this technique builds objects layer by layer. The layering is crucial to how FDM works; it deposits melted filament material onto a build platform, and once one layer is complete, the printer moves up slightly to create the next layer.

This method allows for the creation of complex geometries and shapes, as material is added incrementally. For a typical print job, the number of layers can vary significantly depending on the size and complexity of the object being printed, leading to a final product that may contain many layers, often in the hundreds or even thousands in cases of detailed designs.

Using only one layer, two layers, or a fixed number such as ten does not reflect the core characteristic of FDM, where the iterative process of adding multiple layers allows for the effective formation of the 3D object. This multi-layering approach is essential to achieving the strength, detail, and fidelity needed in most 3D printed parts.
