Object File Format An object file format is a digital representation of a 3D model, containing information about geometry, texture, and material properties. Common formats include STL, OBJ, 3MF, and AMF. These files are essential for 3D printing as they define the model's shape, dimensions, and surface details. OBJ files support complex geometries and textures, while STL is widely used for its simplicity and compatibility. 3MF is preferred for multi-material and color printing due to its advanced metadata support. Proper file formatting ensures accurate slicing, printability, and dimensional accuracy. |
