    about your specific example. By which i simply mean you need a different example.

    3d printing will never advance to the point it can create anything. Shoes are a complex technology just as clothes are.

    You may be able to print out a set of nylon gloves (which you then need to put together) but for most things a general 3d printer just wont be suitable.

      of shoes which look like shoes fairly easily on a good printer, but you are right about the final product.

        and rolls of charts, often with mistakes and guesswork, around the late 1400s.  I suspect that you would agree that technology for determining your current location has improved.

        While 3-D manufacturing right here and now may not make a shoe, give it a year or three, and it will.

        NASA had (last time I checked was 2 yrs ago) a very talented blacksmith on its staff. I know, because he taught me some techniques on toolmaking and treatment of metal, such as hardening it without causing it to be brittle). He was a great guy - a metallurgist PhD, who kept an anvil, a coal forge, and a gas forge in his lab. Man, could he smith. What a talent. What a warped sense of humor, too.

        HIs key job? The engines powering the lift-off of the space shuttle had a complex titanium part that they could not manufacture properly in a factory. Instead, they relied on him to hand fashion the part for each engine, and for each test firing. That's right, one of the most modern and powerful engines relying on the second oldest profession  to work.

        Because that engine design was so robust and effective, I suspect that it will be used in future craft for some time to come. BUT, Nasa did announce that certain parts for that engine will now be manufactured by 3-d technology, using titanium.  

        My point is, his job is about to be replaced with a 3-d machine, a technology that currently mimics an iron needle in a bowl of water, trying to point north.

        What we call god is merely a living creature with superior technology & understanding. If their fragile egos demand prayer, they lose that superiority.

      advance to the point where you can make anything as long as you have enough of the raw elements (carbon, oxygen, nitrogen, gold, etc) available.  That includes things like an already "cooked" steak, a new set of clothes, or even another such printer.  That is because it would be a full blown universal constructor (i.e. tabletop nanofactory) similar to the matter compiler in The Diamond Age and the cornucopia machine in Singularity Sky.

      •  I don't know when you expect that to happen (4+ / 0-)

        but I seriously doubt I'll see it in my lifetime (i.e., the next 40 or 50 years, if no disaster strikes.)

        I'm no chemist, but I know this much: Every chemical reaction is different. Every reaction requires its own reagents, has its own optimal temperature and pressure conditions, and may have specific containment requirements. Every reaction produces different byproducts, which are often toxic. And the desired byproducts of each reaction will have different physical characteristics -- some will be solid, some liquid (and possibly corrosive), and some gaseous.

        How you design a machine that can start from basic elements and create any chemical product (and everything is a chemical product) is beyond me, but its complexity would be beyond Jules Verne raised to the Rube Goldberg raised to the Dr. Seuss. And it still won't be able to make you a decent cup of tea.

        Let us all have the strength to see the humanity in our enemies, and the courage to let them see the humanity in ourselves.

        I've read articles where people are claiming that you'll be able to 3D print  your shoes at home. this would of course mean that you had all the raw materials necessary, a 3D knowledge about how to use, time to do it and space to store the printer and materials. It would be more efficient to simply buy them from Reebok, New Balance or Nike.

        It is a lot harder to create a complex  molecule from items off hte periodic chart than you think.

      •  We are still a long way from "Replicators" (0+ / 0-)

        We still have not developed a practical home energy source to power such a device - (or those flying cars).

        Kind of like dreaming about Ipads in 1899.

        Still love Star Trek as much as anyone though.
