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

Our free and fast tool will convert most 3MF model files to a standard STL 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 your STL file will be converted and ready for download shortly afterwards. For more information about the 3MF to STL conversion process see the conversion information section below for more information.

FAQ

What STL formats can I convert to?

Our tool will save all STL files in binary format. Optionally, our tool will allow you to save to the non-standard color STL format.

How can I convert my 3MF file to STL?

First click the "Upload..." button, select your 3MF file to upload. Select any configuration options. When the 3MF to STL conversion has completed, you can download your STL file straight away.

How long does it take to convert my 3MF to STL?

We aim to process all 3MF to STL conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.

How accurate is the 3MF to STL conversion?

We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features being added every week.

Is it safe to convert my 3MF to STL on ImageToStl.com?

Yes, of course! We do not store the 3MF file you submit to us. The resulting STL file, once created is deleted 1 hour after upload and the download link will expire after this time.

Can I convert 3MF to STL on Windows, Linux, Android, iOS or Mac OS?

Yes! Our 3MF to STL tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

File format information for 3MF to STL

Extension: 3MF

Full Name: 3D Manufacturing Format

Type: 3D Model

Mime Type: application/vnd.ms-package.3dmanufacturing-3dmodel+xml

Format: Binary

Description

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 Notes

If your 3MF file contains textures, these will be ignored. If a material contains color information this will be translated where possible.

Supported Features

  • Mesh geometry
  • Face and vertex colors

Unsupported Features

  • Textures

Extension: STL

Full Name: Standard Triangle Language

Type: 3D Model

Mime Type: application/vnd.ms-pki.stl

Format: Text & Binary

Description

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.

STL Notes

The standard STL file format does not support colored faces or vertices or texture information. The STL file generated by the tool will contain only raw mesh/triangle data by default which is perfect for 3D printing.

The tool also has an option to save the file to one of the non-standard formats that support colored faces such as VisCAM and SolidView which is perfect if you want to further process the STL in software which supports these formats.

Supported Features

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