3D objects files (.obj) are most likely one of the most common and widespread files for 3D modeling purposes and as such frequently used for 3D printing. It is thus no surprise that many 3D modeling or 3D conversion programs support the obj to stl conversion, which is actually the quintessential format for 3D printing.

Understanding OBJ and STL file formats
The OBJ file format is a widely used format for 3D models. It is a simple, text-based format that represents 3D geometry, including the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon. OBJ files are commonly used in 3D graphics applications and are supported by many 3D software packages.
The STL file format, on the other hand, is a file format native to the stereolithography CAD software created by 3D Systems. STL is widely used for 3D printing and computer-aided design. It describes only the surface geometry of a three-dimensional object without any representation of color, texture, or other common CAD model attributes.
How to convert OBJ to STL
Converting an OBJ file to an STL file is a common task in 3D modeling and printing. This conversion allows you to take a 3D model created in a software that exports OBJ files and prepare it for 3D printing, which often requires STL files.
Best software for OBJ to STL conversion
One of the best software options for converting OBJ to STL is MeshLab. MeshLab is an open-source, powerful tool for processing and editing 3D triangular meshes. It supports a wide range of file formats, including OBJ and STL, making it an excellent choice for file conversion.
To convert an OBJ file to STL using MeshLab, follow these steps:
- Open MeshLab and load your OBJ file by clicking File → Import Mesh.
- Once the file is loaded, you can view and edit the model if necessary.
- To convert the file, go to File → Export Mesh As and select STL as the output format.
- Save the file, and your OBJ file will be converted to an STL file.
Alternative converters
Another popular tool for converting OBJ to STL is Blender. Blender is a free and open-source 3D creation suite that supports the entire 3D pipeline. To convert using Blender, import your OBJ file, then use the File → Export → STL option to save your model as an STL file.
