What GLTF and 3MF files are
GLTF
glTF (GL Transmission Format) is an open 3D format from the Khronos Group, often called the JPEG of 3D. A .gltf file describes the scene in JSON and can point to separate binary and texture files, and it loads quickly in web viewers and game engines with support for realistic PBR materials and animation.
3MF
3MF (3D Manufacturing Format) is the 3D printing format of the 3MF Consortium, founded in 2015 by Microsoft and other industry members. A 3MF file is a ZIP package holding the model in XML with its units, colours, materials and the placement of every object on the build plate, and it is the project format of slicers such as PrusaSlicer, Bambu Studio and Cura.
