STL and OBJ files are two common formats used in 3D modeling and printing. Here’s a quick overview of each:
| Files Type | STL Files | OBJ Files |
|---|---|---|
| Format: | STL stands for “Stereolithography.” | OBJ is a standard 3D image format developed by Wavefront Technologies. |
| Purpose: | Widely used in 3D printing and computer-aided design (CAD) for representing the surface geometry of a 3D object without any color, texture, or other attributes. | Commonly used for 3D modeling and computer graphics, especially when color, texture, and detailed geometry are important. |
| Structure: | Consists of a series of triangles (facets) that make up the surface of the model. | Can store complex geometry, including vertices, edges, faces, and textures. OBJ files are often accompanied by an MTL file that stores material and texture information. |
| Advantages: | Simple and universally supported by most 3D printers and CAD software. | Supports detailed information, including textures, colors, and multiple objects within a single file. |
| Limitations: | No support for color, texture, or complex geometry details like curvature or edges. | Larger file sizes and may be more complex to work with compared to STL. |
