.3mf file type

Post by Antares »

Hello people

I ask about .3mf file type for Freecad, because a lot of resin printer slicers support it. It seem is really light than .stl and has more information, and no need triangles to pass information.
There exist some project to including it in the list of type of files than FreeCAD can export?
People maker, like me, will be thankful
Thanks you
Jordi.

PD: We can export files to .stl, but if we import .stl files is not possible to edit or modify
Thanks you
Jordi.

I haven't tried it, but there is an online converter (supposedly free) that can take step files and convert them to 3mf

Here are the (simplified) specs of the file format: https://en.wikipedia.org/wiki/3D_Manufacturing_Format

So, to support meshes this shouldn't be very complicated to implement our own exporter (and maybe importer).

The complete specs can be found here: https://3mf.io/specification/

Solution #1: MakePrintable Press “Upload Files” and choose your 3MF file. Select “Quick Repair”. This may take several minutes. Click on “Save/Export”. Choose “3D model” and then STL. Press “Download”, and your file should start downloading to your computer.

Is this 3MF export supported only in the Mesh workbench?

I've been starting to use 3MF more often, in place of exporting as STL for 3D printing. When choosing File --> Export for a part primarily designed in PartDesign, I'm not seeing 3MF as an option in the dropdown.

Thanks,

John

Currently it's only accessible in the Mesh wb's own export function. But sure I can add it to the global export dialog, too.
