- October 2, 2016

Found this old video I made a few years ago. Still pretty neat. The printer is a giant self built Delta, which has since been deconstructed and turned into a laser cutter.

Sculpting in VR

My wife sells 3D printed sterling silver jewelry (Nün&Noot). She currently uses a combination of clay and digital sculpting tools to design her very organic pieces.
