Im still learning how to make "real" action figure joints (ball/swivel/hinge/etc) But in the meantime, Ive had "make an action figure that looks like my son" on my bucket list for a while.
I used the iphone X face scanner and em3d to scan his face, then put it on a "flexi" robot model https://cults3d.com/en/3d-model/art/flexi-print-in-place-fokobot-2-0
Heres the result:
I used blender, and its built in "3d print" module to make the scan manifold, and joined the models.
