What computer file represents an AM part as layers and automatically generates the toolpaths for an AM procedure?

The computer file that represents an additive manufacturing (AM) part as layers and automatically generates the toolpaths for an AM procedure is G-code. G-code is a language used to control CNC machines, including 3D printers. It consists of a series of commands that guide the printer on how to move the print head, how much material to extrude, and other operational parameters necessary for the additive manufacturing process.

When an AM model is sliced using slicing software, the software converts the 3D digital model into layers, preparing the necessary instructions for the printer in G-code format. This process involves determining the specific paths that the printer will follow for each layer based on the geometry of the part, the type of material being used, and the printing settings selected.

In contrast, STL files are commonly used to represent 3D models in terms of surface geometry, but they do not contain information on how to slice the model into layers or generate toolpaths directly. CAD files represent the design intent of parts but also lack the specific slicing and path information needed for actual printing. OBJ files are similar to STL files, providing 3D model geometry but do not inherently include layering or toolpath functions. Therefore, G-code is essential for translating the layered representation
