What does the term "slices" refer to in 3D printing?

In the context of 3D printing, the term "slices" refers to the layers of material that are printed one on top of the other to create a three-dimensional object. When a 3D model is prepared for printing, it is typically processed by slicing software that breaks the model down into thin horizontal layers or "slices." Each slice represents a cross-section of the object, and the printer builds the object layer by layer, following these predefined slices.

This layering process is crucial because it allows for the precise reproduction of complex geometries and details found in the 3D model. As the printer lays down each layer, it gradually constructs the complete object, helping to achieve the desired shape and structure. Understanding slices is essential for anyone involved in 3D printing, as it directly influences the quality and success of the final print.
