Convert Your 3D Mesh/Model STL Files to 3MF

Our free and fast tool will convert most 3D mesh or STL (Standard Triangle Language) model files to a standard 3MF (3D Manufacturing Format) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing.

To convert your STL file click the Upload button above and select the file to convert. Once selected, the file will be converted to a 3MF file and will ready for download shortly afterwards.

STL Notes

Standard STL files do not contain material or color information so this cannot be imported. There are however two formats (VisCAM and SolidView) that attempted to add color information to the STL file format. If our tool detects this additional color information it will attempt to import this information.

Supported Features

  • Mesh geometry
  • Face colors via the VisCAM and SolidView formats
  • Binary and Text versions supported

3MF Notes

3MF files support material and color information. If your uploaded model contains color information our tool will attempt to save this in the 3MF file at the end of the conversion process. Texture information is not supported at this time.

Supported Features

  • Mesh geometry
  • Face and vertex colors

Unsupported Features

  • Textures
