You've all probably seen my stories about projects being made with the new 3d printer, but here's some photos of it in action. My Form One is printing cylindrical concrete telephone booths. The real Southern Pacific Railroad put the full-sized ones along the railroad tracks in rural locations. (Real booth in the Sacramento Valley.) In the days before radio, they gave crews a way to talk with the dispatcher.
The clear resin and multiple cylinders make this print job a bit closer to fireworks than most of my prints!
