Convert BREP to AMF Online
Convert BREP to AMF in seconds. BREP is a raw boundary-representation CAD export; AMF's strength is this: carries color/material data beyond plain STL geometry. No software installation required — everything runs in your browser.

Why Convert BREP to AMF?
Our engine reads a file built around exchanging exact CAD surface geometry between engineering tools and rebuilds it aiming to preserve this: carries color/material data beyond plain STL geometry — rather than producing a generic, lowest-common-denominator result.
BREP is a raw boundary-representation CAD export, commonly used for exchanging exact CAD surface geometry between engineering tools. That focus comes with a real limitation: a lower-level format most non-CAD software has no importer for. AMF doesn't share that problem — its strength: carries color/material data beyond plain STL geometry.
If you need a file built for 3D printing with color and material metadata, an early alternative to 3MF but only have one built for exchanging exact CAD surface geometry between engineering tools, converting is usually the fastest path — BREP and AMF serve different enough purposes that recreating the asset from scratch rarely makes sense.
How to Convert BREP to AMF
- Upload your BREP file.
- MiConvert converts it to AMF, aiming to preserve what makes AMF useful: carries color/material data beyond plain STL geometry.
- Download the converted AMF file.
- Use it directly with some legacy 3D-printing tools.
Key Conversion Features
- Keeps the parts of your file that matter for 3D printing with color and material metadata, an early alternative to 3MF intact, even though the source was built for exchanging exact CAD surface geometry between engineering tools
- Fast turnaround, typically under a minute per file
- Produces output ready for some legacy 3D-printing tools, picking up right where CAD kernels like OpenCascade left off
- Understands that BREP is a raw boundary-representation CAD export and AMF is an XML-based additive-manufacturing format, rather than treating the conversion as a blind format swap
- Bridges the gap between BREP's focus on exchanging exact CAD surface geometry between engineering tools and AMF's focus on 3D printing with color and material metadata, an early alternative to 3MF

Frequently Asked Questions
Can I convert the file back from AMF to BREP afterward?
Only what AMF actually carries can come back — anything specific to BREP's role in exchanging exact CAD surface geometry between engineering tools that didn't survive the original conversion won't reappear.
Do I need CAD kernels like OpenCascade installed to convert my file?
No — the conversion happens entirely on our servers. You don't need CAD kernels like OpenCascade, and you don't need some legacy 3D-printing tools either unless you plan to open or edit the AMF result afterward.
Will I lose anything converting BREP to AMF?
Converting to AMF means adapting to a real constraint: far less widely adopted by current slicers than 3MF became. Anything BREP carries — built as it is for exchanging exact CAD surface geometry between engineering tools — that has no equivalent there won't make the trip, but the core content converts faithfully.
What software works with the converted AMF file?
AMF is used by some legacy 3D-printing tools. If you were working with CAD kernels like OpenCascade (which produces BREP), this conversion is the direct bridge between the two.
What's the real difference between BREP and AMF?
BREP is built around exchanging exact CAD surface geometry between engineering tools (a raw boundary-representation CAD export). AMF is built around 3D printing with color and material metadata, an early alternative to 3MF instead (an XML-based additive-manufacturing format) — different enough that this is a genuine format conversion, not just a rename.
