Convert FCSTD to AMF Online
Convert FCSTD to AMF in seconds. FreeCAD (FCStd) is FreeCAD's native parametric project format; AMF's strength is this: carries color/material data beyond plain STL geometry. No software installation required — everything runs in your browser.

Why Convert FCSTD to AMF?
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 open-source parametric CAD design with a full feature history, converting is usually the fastest path — FreeCAD (FCStd) and AMF serve different enough purposes that recreating the asset from scratch rarely makes sense.
Our engine reads a file built around open-source parametric CAD design with a full feature history and rebuilds it aiming to preserve this: carries color/material data beyond plain STL geometry — rather than producing a generic, lowest-common-denominator result.
The short version: FreeCAD (FCStd) is optimized for open-source parametric CAD design with a full feature history, AMF is optimized for 3D printing with color and material metadata, an early alternative to 3MF, and this converter exists for the moment those two needs don't line up.
How to Convert FCSTD to AMF
- Upload your FCSTD 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
- Fast turnaround, typically under a minute per file
- No local software installation required for either side — not FreeCAD, not some legacy 3D-printing tools — everything runs in the cloud
- Converts FCSTD into AMF, aiming to preserve what matters most: carries color/material data beyond plain STL geometry
- Purpose-built for the shift from open-source parametric CAD design with a full feature history to 3D printing with color and material metadata, an early alternative to 3MF, not a generic pass-through
- Produces output ready for some legacy 3D-printing tools, picking up right where FreeCAD left off

Frequently Asked Questions
Will I lose anything converting FCSTD to AMF?
Converting to AMF means adapting to a real constraint: far less widely adopted by current slicers than 3MF became. Anything FreeCAD (FCStd) carries — built as it is for open-source parametric CAD design with a full feature history — that has no equivalent there won't make the trip, but the core content converts faithfully.
How long does the conversion take?
Most conversions finish in 10-30 seconds. Larger or more complex files can take up to a minute.
What's the real difference between FCSTD and AMF?
FreeCAD (FCStd) is built around open-source parametric CAD design with a full feature history (FreeCAD's native parametric project format). 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.
Why does AMF exist as a separate format instead of everyone just using FCSTD?
Because they're built for different jobs — FreeCAD (FCStd) is aimed at open-source parametric CAD design with a full feature history, while AMF is aimed at 3D printing with color and material metadata, an early alternative to 3MF. Neither format is "better," they just fit different parts of a workflow.
Why would I need AMF instead of just keeping FCSTD?
Mainly when your workflow specifically calls for 3D printing with color and material metadata, an early alternative to 3MF — that's AMF's whole reason for existing, and FreeCAD (FCStd) isn't built to provide it, since it's focused on open-source parametric CAD design with a full feature history instead.
