Our free and fast tool will convert most 3D mesh or STEP (STEP-File) 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 STEP 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. For more information about the STEP to 3MF conversion process see the conversion information section below for more information.
Here are 2 simple steps to convert your STEP to 3MF.
First click the "Upload..." button, select your STEP file to upload. Select any configuration options. When the STEP to 3MF conversion has completed, you can download your 3MF file straight away.
We aim to process all STEP to 3MF 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 being added every week.
Yes, of course! We do not store the STEP file you submit to us. The resulting 3MF file, once created is deleted 1 hour after upload and the download link will expire after this time.
Yes! Our STEP to 3MF tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.

The STEP file format is a 3D format defined in 1994 and used to store 3D objects for use in Computer-aided design (CAD) applications. STEP files are text-based formatted files containing one instance per line.
Although STEP files are widely supported by most CAD applications the format does have its limitations, such as the necessity to read the complete file into memory in order to parse the contents and due to the text storage of information the files can be quite large.
STEP files when imported will be converted to 3D geometry comprising vertices and faces. If the STEP file contains color information this will be converted where possible.

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 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.
