Free Online 3MF to OBJ Converter

Here is our free to use 3MF to OBJ 3D model converter tool that will take your 3MF file and convert it to the OBJ format ready for loading into your favourite 3D modeling package. Our 3D model converter supports batch processing of your files and can convert up to 20 3MF files at one time.

Select File(s)

Drag and drop your files here to upload or click the button above.
A maximum of 20 files can be converted at once.

Please note: Your 3MF file file, when uploaded to our server, will be deleted 15 minutes after upload. Please download your converted 3MF file file before this time.

The 3MF to OBJ model conversion tool will analyse your 3MF file and convert its 3D mesh data including vertices, surfaces and where applicable vector normals and texture coordinates to the OBJ format whilst maintaining the structural accuracy of your original 3MF 3D model file.

File information for 3MF and OBJ

Full Name	3D Manufacturing Format
Extension	3MF
Type	3D Model
Mime Type	application/vnd.ms-package.3dmanufacturing-3dmodel+xml
Format	Binary

The primary purpose of the 3MF format is to store and transmit 3D models for 3D printing. The format is ideally suited to this due to its ability to store not only the 3D model but also additional metadata required for 3D printing an object, such as units of measurement, surface material characteristics, and more.

Mesh Geometry

The 3MF file format is a mesh-based format; more specifically, the mesh is stored as a series of triangles that, when combined, can represent any 3D object. The format can contain many 3D mesh objects in a single file.

3MF Converter Capabilities

As materials containing texture and color information are both supported by the 3MF format, our tool will do its best to include these materials, including any texture files, in the converted file.

Full Name	Wavefront
Extension	OBJ
Type	3D Model
Mime Type	text/plain
Format	Text

An OBJ file is a text-based file format used for the storage of 3D model data. The format was developed in the 1980s by Wavefront Technologies as a means to store the geometric mesh data associated with a 3D model. It has garnered widespread support in the following years, and you will find options to load from and save to the OBJ format in most modern 3D modeling applications.

As OBJ files are essentially text files, they can grow quite large when working with large and detailed 3D models.

Mesh Geometry

Within a 3D OBJ file are lists of vertices, mesh faces, face normals, texture coordinates, and more. The vertices, normals, and texture coordinates are stored in a continuous list and are indexed referenced within a separate list of mesh faces, ensuring optimal use of space within the file. A mesh face may contain three or more points, each of which can use a unique vector normal and texture coordinate.

OBJ Converter Capabilities

As materials containing color information is supported by the 3MF and OBJ formats, our tool will do its best to include this in the converted OBJ file.
