Our free and fast tool will convert most 3D mesh or STP (STEP-File) model files to a standard AMF (Additive Manufacturing File) 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 STP file click the Upload button above and select the file to convert. Once selected, the file will be converted to a AMF file and will ready for download shortly afterwards. For more information about the STP to AMF conversion process see the conversion information section below for more information.
Here are 2 simple steps to convert your STP to AMF.
First click the "Upload..." button, select your STP file to upload. Select any configuration options. When the STP to AMF conversion has completed, you can download your AMF file straight away.
We aim to process all STP to AMF 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 STP file you submit to us. The resulting AMF file, once created is deleted 1 hour after upload and the download link will expire after this time.
Yes! Our STP to AMF 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 STP 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.

The STP file format is a 3D format defined in 1994 and used to store 3D objects for use in Computer-aided design (CAD) applications. STP files are text-based formatted files containing one instance per line.
Although STP 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.
STP files when imported will be converted to 3D geometry comprising vertices and faces. If the STP file contains color information this will be converted where possible.

The AMF or Additive Manufacturing File format is an open standard 3D file format primarily used within additive manufacturing processes such as 3D printing. The initial release version of the file was in 2011 and the format continues to be developed today.
As this is a 3D file format the contents which are Xml based describe one or many 3D objects broken down into solid volumes defined with vertices and triangles. The format has support for color and texture materials.
