Surely it is the process - as you can create multiple designs in one print run without having to set multiple different machining tools in process at the same time to produce them? He mentions it at the beginning.
It is just a tube, but where the design improvements come in is being able to produce tricky shapes that are difficult to consistantly produce with molten metal mould processing or cutting. Did I imagine it or have Campag been producing a derailleur arm with 3D printing to reduce weight that can't be achieved with conventional methods?
It may have all sorts of medical and aerospace uses but in many respects with bicycles it's still a solution looking for a problem.
Hmmm more precisely it's SLS (selective laser sintering).
So they're proud of a copying a bent-tube-with-plate dropout design & adding their logo twice? Did their tube bender break?
The skill is not the process (as anybody can send a STL file to somewhere like Shapeways & receive parts exactly like these) but about the design.
