Here are 2 simple steps to convert your STL to 3MF using our fast and free STL converter tool.

The STL file format has its roots in the 1980's and is the native file format for 3D Systems stereolithography CAD software. The format defines a triangulated mesh with vertices and faces and is a popular format for sharing 3D printable model files.
There were several formats that attempted to extend the STL format namely SolidView and VisCAM whose formats included limited 15-bit color information for each mesh face which is often ignored by most modern 3D software. The STL format can be either Text or Binary, our tools will support both formats.

When converting 3D Model/Mesh files using our [ey] converter we will attempt to convert color materials into a suitable format for use in the converted file.
| Extension | 3MF |
| Full Name | 3D Manufacturing Format |
| Type | 3D Model |
| Mime Type | application/vnd.ms-package.3dmanufacturing-3dmodel+xml |
| Format | Binary |
3MF files are a modern 3D file format designed specifically for use with 3D printable models (additive manufacturing). It was designed to be the successor to the popular legacy STL format (also a common format in 3D printing) to overcome the limitations of that format.
The format of 3MF files is XML based that are compressed with the standard Zip file compression resulting in small, easily transferable files. The format supports 3D meshes along with associated materials and textures all contained within the Zip file.
3MF Converter Capabilities
When converting your STL to 3MF our tool will attempt to accurately convert any color/material information.
Your STL file will be converted to a 3MF file using our unified 3D model and mesh conversion tool. Our STL 3D tool performs accurate conversions of 3D elements such as vertices, faces, normals and relevant material information. As both STL and 3MF support color material information our tool will also attempt to convert the color information too.
First click the "Upload..." button, select your STL file to upload. Your STL file will be uploaded to our servers. When the STL to 3MF conversion has completed, you can download your 3MF file straight away.
We aim to process all STL to 3MF conversions as quickly as possible, this usually takes around 5 seconds however this can be longer for certain files, so please be patient.
We aim to provide the best conversion experience. Our tools are under constant review and development with new features being added every week.
