Why Convert STP (STEP) to AMF?
STP (STEP) (Standard for the Exchange of Product Data) is a parametric CAD exchange format used in SOLIDWORKS, CATIA, Fusion 360, and NX. While powerful in its native ecosystem, STP (STEP) files often need to be converted to other formats for cross-platform compatibility, visualization, or manufacturing.
AMF (Additive Manufacturing File) is a XML-based format for additive manufacturing with material and color support. Converting from STP (STEP) to AMF enables you to leverage the strengths of the AMF format — whether that's web delivery, game engine integration, 3D printing, or CAD interoperability.
Our online converter handles the entire STP (STEP) to AMF conversion process server-side, so you don't need to install any desktop software, plugins, or CAD licenses. Just upload your file and download the result.

Frequently Asked Questions
Is the STP (STEP) to AMF conversion free?
Yes, our converter is completely free for files up to 50MB. Registered users get extended limits up to 100MB per file.
Will the conversion preserve my model's geometry accurately?
Yes. Our conversion engine uses advanced algorithms to preserve geometry, surface details, and dimensional accuracy as closely as the target format (AMF) supports.
How long does STP (STEP) to AMF conversion take?
Most 3D conversions complete within 10–30 seconds depending on file size and geometric complexity. Maximum processing time is 2 minutes for very large files.
Do I need to install any software?
No. The entire conversion process runs in the cloud. Simply upload your STP (STEP) file and download the AMF result — no plugins, no desktop software required.
Can I send the converted AMF file directly to my 3D printer?
Yes. AMF files are compatible with all major 3D printing slicers including Cura, PrusaSlicer, Simplify3D, and Bambu Studio. Simply import the converted file and prepare your print settings.
Which CAD software exports are supported?
Our converter supports STP (STEP) files from all major CAD platforms including SOLIDWORKS, CATIA, Fusion 360, NX (Siemens), Inventor, Creo, and FreeCAD.
