What is the purpose of a slicer in additive manufacturing?

The purpose of a slicer in additive manufacturing is to convert 3D models into instructions for 3D printers. This software takes the digital representation of a model, which is often in formats like STL or OBJ, and breaks it down into layers that the 3D printer can understand. Each layer is translated into specific movements and actions, detailing how the printer should move, where to extrude material, and how fast to print based on the desired settings. This process is essential because it prepares the model for the layer-by-layer construction that is characteristic of 3D printing.

The slicer also allows users to adjust settings such as layer height, print speed, and infill density, which can affect the quality and finish of the printed object. Thus, the role of the slicer is a critical step in the additive manufacturing workflow, as it bridges the gap between the digital design and the physical object printed by the machine.
