This Nissin 3D bender is kind of like a PlayDoh Fun Factory, except it squirts out 1.25″ steel pipe instead of soft non-toxic-but-funny-tasting dough. Looks like most of the magic is in the bending-die head. [via Boing Boing]

  1. This machine is bending steel tube. I did a lot of that in a previous life with much simpler tools. Short rule of thumb, if it bends then it’s tube. If it doesn’t bend then it’s pipe.

    1. A pipe and a tube are generally the same thing, for the exact differences in their definitions check out the second paragraph in this Wikipedia article: http://en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

      I think you may be confusing pipe for pole, which is a solid cylindrical object.
