  •  Meh, they're a tad over-rated (2+ / 0-)

    for example, it will cost something like $800 to print out a 2 L bottle full of Classic Coke.

    The local bottling plant, which can do so for a few cents, doesn't have * that * much to worry about . .. .

    •  Just wait. (1+ / 0-)

      •  The beauty of 3D printing is that (4+ / 0-)

        you can make things that otherwise you could never get.

        For example, let's say your (or my) 8-track player breaks and it needs a rather trivial part to be repaired.

        But, to get that part - a $50 million factory is needed to spit out 8,000 of them every hour - that's how they did it in the 70's.

        But today nobody is going to re-start that factory to make that 10 cent part for you or me.  Or even you AND me.  It's just not worth $50 million for them to do so.

        So we're stuck - we could never get the part to repair our 8 track player, at least not until 3D printers come along, which (assuming you already have one) can make the part for a few dollars.  Then Voila, in a few minutes for a few dollars, I'm back to listening to Anne Murray and Terry Jacks in all their 8-track glory.

        That's the promise of 3D printing - OTOH, it has little hope of replacing mass manufacturing of current products.  It is just too expensive.  

        Quite frankly, it is based on 30 year old ink-jet technology - which is cleverly finding new use for 3D manufacturing.  

        But like many things "nanotechnology" related, it is not clear if there is more hype than anything else involved.
