Seth McFaralane uses that with his vinyl action figures. It works great for commercial use when you can grab the cast of the Walking Dead for an hour or two, scan them and print to use in molding for production. Really streamlines the method to get an action figure you can identify and will fly off store shelves, but it's not going to win over any modelers hearts or any contests.
The best 3D printing still hasn't come near the quality of a sculpt when it comes to organic things. They angles in something like a face are too complex. It's like a comparison between injection molded figs and a finely cast resin. It'll never be convincing in small scales, resolution becomes an issue, there's no room in a 1/35 head for layered printing.
However I've never seen the results as good as depicted in those photos, so either they've really upped the technology or the photos are a bit doctored. I do love the way the clothing came out. That's tedious to do by hand.
