The OBJ format was developed by Wavefront Technologies in the 1980s and has become one of the most widely supported 3D file formats.
While OBJ files are easy to work with, they often require separate MTL files for materials and individual texture files, making them cumbersome to share.
3MF (3D Manufacturing Format) was developed by the 3MF Consortium in 2015 as an open standard specifically designed for 3D printing workflows.
This conversion is especially useful when you need to prepare 3D models for 3D printing, as 3MF preserves all manufacturing-related information in a single, compact file.
Converting OBJ to 3MF involves transforming the geometry, material information, and textures from the text-based OBJ format into the structured XML-based 3MF format.
The process requires parsing the OBJ file's vertex positions, normals, UVs, and material definitions, then restructuring them into the 3MF's XML structure with proper references.
Our converter ensures that 3D printing-specific information like model orientation, scaling, and positioning are properly preserved in the 3MF output.
Converting to 3MF offers several advantages for 3D printing: it consolidates multiple files into a single package, preserves manufacturing data, and is supported by most modern 3D printers and slicing software.
An online OBJ to 3MF converter allows you to quickly transform 3D models between formats without installing specialized software. It's convenient for converting models from any device with a browser.
Our converter maintains the original geometry and basic material properties. The 3MF format supports advanced material properties and was designed specifically for 3D printing workflows, so you won't lose information.
Conversion time depends on the model size and complexity. Most conversions complete within a few minutes.
