Hi there
As the population/usage of 3mf files is constantly growing (and maybe one day will be the new standard) I I request to add 3mf file support in order to view 3D models with babylon.js sandbox.
(And also as the support for Microsofts 3D viewer is ending soon and babylon.js sandbox is the suggested successor tool to be used but 3mf support is missing for the moment).
Thank you 
Cheers, Michael
Hey @mikeych welcome to the Babylon.js forums
We recently got 3MF export support thanks to a community contribution: 3MF Support by pandaGaume · Pull Request #17858 · BabylonJS/Babylon.js
We would love if the community contributed an importer too! Meanwhile you could transform your 3MF files into GLTF to load them as a workaround.
Hi Alitar
Thanks for your feedback.
Yes. This is what I am looking for: an importer. I am only using babylon.js to view 3D models either in 3mf or stl.
Cheers, Michael
