Like how some animals can regenerate limbs or like how humans can, uh, make babies, 3D printers can 3D print the 3D printer parts necessary to make more 3D printers. Thankfully, they still require some living person to put these parts together because if they didn’t, they could just start eliminating us one by one as they self-replicate and replace us all.

To reach 1000mph and go supersonic, the wheels they’re using weigh over 230 pounds, nearly 3 feet wide and spin four times faster than a F1 car. Read more…
