This week in 3D printing, we discovered why green screens and St. Patrick’s Day don’t mix, enjoyed some magical dancing sculptures, got a tiny bit scared by some hyper-realistic robots, and watched some holograms try to get in on the 3D printing game.

No word on if it’ll let you rewind last night

Artist Toki’s stop motion sculpture is entirely 3D printed, and incredibly intricate. When light passes through it, an animated dancer appears, similar to a zoetrope. He says he’s trying to express the relationship between time and movement, and to “capture the beauty and nature of time itself.”

And they say robots won’t take over the world…

This skeleton may look like one of the 3D printed hosts in Westworld, but believe it or not, it’s even realer. Weta Workshop’s been creating hyper-realistic endoskeletons for use in movies and beyond, bringing tangibility to sci-fi.

VentureBeat’s Dean Takahashi interviewed Xbox co-founder Seasmus Blackley’s about how he’s working on a way to enable instant 3D printing — with the use of augmented reality and something AR firm Daqri has dubbed as “software defined light.” Much like how lasers inside a 3D printer fuse plastic, Blackley is working to project holograms into tanks of monomer, solidifying the parts touched by the light.
