Publish 3MF embeds the settings you choose into a 3MF file, so the model and its configuration are shared together.

Unlike Save Project, which captures a full snapshot, you pick exactly which settings are required for the print and would be packaged together.

When another user opens it, nothing on the user's setup is overwritten; published settings are just applied on top.

A 3MF that's published from OrcaSlicer will show a little badge on the top-left corner of the file, along with green PUB text next to the file title.

Simply open it just like any 3MF file!

Your printer setup does not change, and the filament/process settings required to print the model are applied directly on top of your existing settings.

A Publish 3MF video guide is also available on our YouTube channel. Link
