Our free and fast tool will convert most 3D mesh or STL model files to a standard CTM 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 file click the Upload button below and select the file to convert. Once selected the file will be converted and 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

CTM Notes

CTM files support per vertex color information. If your uploaded model contains color information our tool will attempt to save this in the CTM file at the end of the conversion process.

Supported Features

  • Mesh geometry
  • Vertex colors
  • All compression versions supported when converting from CTM
