There are three different ways to make a digital 3D object:

1: You can model it, using 3D design software like Blender, Maya, Tinkercad, Sketch-Up or a CAD program.

2: You can download an already existing 3D object from a website like Thingiverse, TurboSquid or The Smithsonian Museum.

OR 3: you can take a 3D scan of an existing object, using a 3D Scanner or photogrammetry.

I’ve been working with 3D scanning for a few years and have gotten some good results. I’ve scanned native masks, glasses frames, dolls, tchotchkes, plants, and other various objects. Each one has it’s own challenges to overcome in order to get a good clean scan.
