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.
Here are 2 simple steps to convert your 3MF to STL.
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.
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.
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.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
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.
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.
Yes. Although you can use an Ad Blocker, if you like our 3MF conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
|Full Name||3D Manufacturing Format|
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.
If your 3MF file contains textures, these will be ignored. If a material contains color information this will be translated where possible.
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.
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.
