Convert 3DM to AMF Online
Convert 3DM to AMF in seconds. 3DM (Rhino) is Rhino's native NURBS surface 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 3DM to AMF?
3DM (Rhino) works well for freeform industrial design, jewelry, and architectural modeling, but has a real limitation: tied to Rhino's own file structure, which most other 3D software can't open directly. Converting trades that for this: carries color/material data beyond plain STL geometry.
AMF was built around 3D printing with color and material metadata, an early alternative to 3MF, which is precisely the gap 3DM (Rhino) leaves open, since it's designed around freeform industrial design, jewelry, and architectural modeling instead.
3DM (Rhino)'s limitation: tied to Rhino's own file structure, which most other 3D software can't open directly. AMF's strength: carries color/material data beyond plain STL geometry — it doesn't share that constraint.
How to Convert 3DM to AMF
- Upload your 3DM 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
- Converts 3DM into AMF, aiming to preserve what matters most: carries color/material data beyond plain STL geometry
- Built to handle the real-world quirks of files meant for freeform industrial design, jewelry, and architectural modeling, not just a textbook version of the format
- Free for files up to 50MB, 100MB for registered accounts
- Purpose-built for the shift from freeform industrial design, jewelry, and architectural modeling to 3D printing with color and material metadata, an early alternative to 3MF, not a generic pass-through
- 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 freeform industrial design, jewelry, and architectural modeling

Frequently Asked Questions
Will I lose anything converting 3DM to AMF?
Converting to AMF means adapting to a real constraint: far less widely adopted by current slicers than 3MF became. Anything 3DM (Rhino) carries — built as it is for freeform industrial design, jewelry, and architectural modeling — that has no equivalent there won't make the trip, but the core content converts faithfully.
What's the real difference between 3DM and AMF?
3DM (Rhino) is built around freeform industrial design, jewelry, and architectural modeling (Rhino's native NURBS surface 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.
Is there a file size limit for this conversion?
Free conversions handle files up to 50MB; registered accounts get up to 100MB.
Can I convert the file back from AMF to 3DM afterward?
Only what AMF actually carries can come back — anything specific to 3DM (Rhino)'s role in freeform industrial design, jewelry, and architectural modeling that didn't survive the original conversion won't reappear.
Is AMF objectively better than 3DM?
Not objectively — AMF is better specifically for 3D printing with color and material metadata, an early alternative to 3MF. For freeform industrial design, jewelry, and architectural modeling, 3DM (Rhino) is still the right tool; that's exactly why both formats exist.
