Which AM output file breaks the 3D part model into layers for machine processing?

STL files are specifically designed for 3D printing applications and serve as the standard file format for additive manufacturing. The crucial function of STL files is to translate a 3D part model into a series of triangular facets, effectively providing the necessary information for slicing software to interpret and manipulate the model.

When an STL file is processed by slicing software, it breaks down the model into layers based on the desired layer height set by the user. Each layer corresponds to a cross-section of the 3D model, allowing the printer to construct the part layer by layer. This functionality is essential for additive manufacturing, as it guides the printer in the precise deposition of material, ensuring that the final part is built accurately according to the original design.

In contrast, OBJ files, while they can represent complex geometries, do not inherently include layer information for 3D printing, making them less suitable for this specific application. AMF files are also intended for 3D printing, but they focus on enhancing the information provided in STL files, such as support structures and color data, rather than breaking down the model into layers in the same manner. DXF files are primarily used for 2D vector graphics and are not tailored for 3D printing processes
