      When the first pieces were tried there was an attempt to break them, to show that "mere plastic" just would not do. Sure enough the piece disassembled and a chunk went flying across the room. As comments were being made about inferior product someone retrieved the broken part. The nylon had held, but a steel pin had not. There were no more arguments about 'cheap plastic' from then on.

    Xerox officials held an emergency press conference Wedensday to announce a
    total recall of all Reprotron 5000 Three-Dimensional Copy Machines.

    Xerox stock has plummeted to a new all-time low since the release of the
    innovative device. Xerox hailed the Reprotron 5000 as a "new revolution in
    copying" when it introduced the machine just two weeks ago, and market
    insiders were certain that the copier would send Xerox stock through the
    roof.

    At a demonstration of the Reprotron in August, Xerox staffers made full
    three-dimensional copies of an Oriental vase, a bowl of fruit, and a perfect
    red rose. Reporters were invited to sample apples and oranges copied from
    the original fruit, though Xerox technicians did warn that the copied fruit
    might taste slightly of toner. John Thompson (inventor of the Reprotron)
    stepped forward to make a copy of a Manhattan phone book, but accidentally
    copied his hand and forearm. He quickly disposed of the highly detailed,
    frantically wiggling half-limb as it slid out of the copier's delivery slot.

    But Xerox wasn't ready for what happened next. "We assumed that people would
    behave as responsible, thinking human beings with this copier, and obviously
    we were wrong," Thompson states. From all across the USA, reports have been
    filing in of the copier being used in what Thompson calls "sick, greedy
    ways."

    At a Copy Center in Austin, Texas, a couple was arrested for making 15
    copies of their three-year-old son, Jeremy, and then refusing to pay for the
    copies, claiming that some of the new children were "smudged." Local
    authorities were uncertain as to which charges should be pressed.

    In Union City, Arizona, Treasury Department officials are investigating
    reports of a secretary who allegedly copied a single bar of gold bullion 150
    times. A task force investigator stated, "Granted, it takes money to make
    money, but we're almost certain that this action is in violation of some
    laws."

    Xerox officials are also under fire from consumers, due to rumors that the
    three-dimensional copying technology is imperfect. Harold Butz of Peoria,
    Pennsylvania, made a copy of a common cement brick spray-painted gold. Butz
    claims he was "shocked and dismayed" when he discovered that the
    machine-made copy was 22-karat solid gold. "All I wanted was a really good
    copy of a cement brick spray-painted gold'" Butz stated. "What the hell am I
    going to do with this thing?"

    Xerox plans to scrap all the machines they are able to recall, but Thompson
    expressed concern over the so-called "black market Reprotrons."

    "Apparently some sick and greedy people discovered that if they had two
    machines, they could use one to make a working copy of the other," Thompson
    revealed. "To tell the truth, we only sold two machines in all - to the
    Cappelli family, a New Jersey based Meat packing firm. These copy pirates
    should be aware that as with anything that is copied from a copy and so on,
    there are bound to be defects in the copies produced. We have no idea what
    kind of stuff will pop out of the slot when a person copies something on a
    fourth- or fifth-generation machine." Thompson declined to comment on
    reports that hundreds of the pirated machines have a human thumb attached to
    the coin slot which constantly wiggles - the result of a person's thumb
    getting in the way during one of the original copier-to-copier copies.

    "Ultimately, we're not too worried," Thompson stated. "People owning the
    copiers will eventually run out of the fluid that make the machine work, and
    we've taken all the fluid off the market. A machine can only last two weeks
    or so without a fluid refill, and there won't be any fluid refills." When
    asked why people with copiers couldn't simply make copies of the fluid
    cannisters they already have, Xerox officials hastily ended the press
    conference, stating that they "need to reconsider a few things."

Among other things, this means that you can't use a 3D printer to fabricate pre-assembled complex machinery: you'd need some other device to assemble the parts.

Of course, since we wanted a polycarbonate product, we only looked at companies that had 3D printers that worked in polycarbonates. So that's a highly biased sample.

      • "raw materials are relatively cheap" -- Are they? What form do raw materials have to be rendered into to be suitable for input to a general-purpose assembler?
      • goods distribution as opposed to raw materials distribution is "inefficient from an energy perspective" -- Why would shipping the specific goods someone wanted be more expensive in terms of energy than shipping them raw materials for things they may or may not want? And why is non-centralized assembly assumed to be cheap in terms of energy? Is this a magical appliance that doesn't use energy?
      • "think about the recycling applications" -- Waste is intrinsic to all energetic processes. Processing resources out of waste is intrinsically costly and also creates a buildup of unprocessable waste in the system (or more technically, leads to a point of diminishing returns in which the reprocessing of remainder waste becomes economically unfeasible).

      You also decline to discuss the issue of economies of scale in mass production. If general-purpose assemblers become cheap, then don't specialized assemblers become even cheaper? At the very least, you can use general-purpose assemblers to create special-purpose ones. The special-purpose ones will then produce the particular goods faster and cheaper.

    2. Re:This is an issue of distribution... by einTier · · Score: 2
      I think I can answer your question.


      Would replicators be expensive? Undoubtably, yes. Few people today actually own a photocopier, but almost everyone has access to one. The cost of the machine doesn't seem to get in the way of producing very cheap copies of pages. I suspect that the cost of a replicator would be the same. Perhaps in the future you can buy your raw materials at Wal-Mart, bring them to the front and tell the replicator what you'd like. Or, better yet, you tell it what you want, it builds it and gives you a bill for the power and elements it consumes, with a small markup to cover the cost and maintenence of the machine.


      Now, the big question. Why should this be cheaper? It should be cheaper in much the same way that robotic factories are generally cheaper than ones staffed by workers. You're not paying for labor anymore. Most of the money in production goes to actually building the product, not the raw materials involved in building. But that's not the only reason. Let's look at yours:


      Equipment: Yes, the replicator will be expensive. However, how expensive is a factory? You don't exactly see them being built everyday, but their cost is covered in the cost of every manufactured product you buy. You even pay for a processing plant, machines, and distribution on the produce you buy at the grocery store. No matter how expensive the replicator is, I have serious doubts that it would anywhere near as expensive as a moderate-sized factory (and should be more useful and for a longer period of time).


      Energy: Good question, because this is a huge unknown. Who knows how much power a molecular replicator should consume? However, I would suspect it would be at least as effecient as the factories and human labor we have in place today. I would hope that it would be more productive cost-wise than humans.


      Time: How quick do you really need your item? How quick can the machine build it? It might well be possible to build something with a replicator than it is through conventional processes. In theory, it should be faster, just because you don't have to machine and assemble complex items -- or wait for organic ones to grow. Even if it is slower, how much slower does it need to be before it impacts the cost of the items coming out of it?


      Waste: Well, there shouldn't be any waste -- other than the waste discussed in energy above. You put raw elements in, and you get an item out. Whatever you need is used up, the rest stays in raw form, ready to be made into something else. Currently, production generates a lot of waste product that cannot be used at all. This should theoretically cut out waste altogether.


      Raw materials: This shouldn't even factor in. You've got to have the raw materials to begin with in normal production. There's no reason this item should be any more or less expensive than it is in traditional manufacturing. Granted, some elements will be very expensive -- but you really don't see much platinum used in every day life, do you? For some, such as titanium, being able to work with the elements themselves and not have to machine it will dramatically cut production costs (titanium isn't expensive or rare, it's just fighteningly difficult to work with).


      Now for your biggies: R&D and design costs, which are really the same thing. In our current copyright world, I think these two things will be prohibitively expensive. People will try to recoup the lost money by either a)charging an enourmously high price for the initial item -- once purchased it can be infinately copied or b) charging immense prices for templates, which cannot be copied, and produce uncopyable items, and possibly a royalty on each item produced. I think this is what kills a replicator in today's world.


      However, I think in a future world, where copyright isn't paramount, maybe things like open source can be expanded to include all things. And, perhaps development will be easier because someone could say "it would be really cool if I could build this, but I'd need this, this, and this which I cannot currently build -- but now that I have a replicator, I can easily obtain these items."


      Of course, this almost completely destroys the capitalist system, because there is no value in objects any more. I'm not entirely sure how I feel about that.

      2. Energy: It makes sense that hi-res fabrication will consume more energy than traditional production. Of course, less energy will be spent on transport.
      3. Time: Replication takes longer than traditional production. But production+shipping could take longer than replication. And I think the machines will get faster.
      4. Waste: It seems like a replicator using a uniform raw material would produce waste of the same material (possibly fused, melted, charred or otherwise altered) that could be recycled into the raw material.
      5. Distribution: ?
      6. Raw Materials: We could have a cost-effective infrastructure for delivering these. Stage 1: people buy 75 pound bags at a store. Stage 2: Tanker trucks fill tanks under your lawn (as is done with heating oil in the northeast US). Step 3: Material flows through pipes under the streets and each replicator has a feed hose. Note that each of these delivery mechanisms is cheaper than moving the equivalent mass of finished goods, because the material takes less space and because there is no switching, or decision-making. In comparison with a five-pound parcel shipped via UPS, five pounds of raw material will take a much simpler (thus cheaper) route.
      7. R&D / Design: Of the replicator or part? If part, I think we'll see a lot of free designs on the net. (To avoid the thorny question of proprietary designs.)
      Why would shipping the specific goods someone wanted be more expensive...
      Because raw material might lend itself to bulk handling technologies, like pipelines and pumps. Also, no packaging materials.

      I guess the relationship of dedicated production equipment to replicators will be like that of CD pressing plants to CDRs. One is cheaper when a large quantity is needed; the other lends itself to ad-hoc production of customized units.

    It's an interesting counterargument. The fact is that a special-purpose computer is faster than a general-pupose computer for any real-world algorithm which turns out to be computational expensive. That is one of the main reasons why we have ASICs. However, an ASIC is not necessarily cheaper, since many algorithms run fast enough on the general-purpose processor, and the separate chip would not pay for itself given the lack of demand.

    It might be that a general-purpose fabricator would prove to be fast and cheap enough for some common goods, and so undercut the need for mass manufacturing of those goods. However, I think this remains entirely speculative given that we don't have anything like a general-purpose fabricator today, and don't know what its characteristics would be. It probably wouldn't work anyway -- see the current Scientific American, in which the world's only nanotech Nobelist explains why there will never be a nanoassembler

    Of course, there is a wide range of possible special-purpose fabrication techniques well short of the dream of general-purpose fabricators, and some of these might be useful for distributed manufacturing. Food and clothing come to mind. Reprogrammable cell cultures together with a robotic chef might be able to make reasonable biological simulacra of most possible foodstuffs, while a robotic loom/sewing machine could produce a great deal of high quality clothing. I submit that in either case, the specialization would allow for faster and cheaper production of the goods than attempting to build them molecule by molecule -- if that were even possible.

    You're repeating something that's also been said elsewhere in the thread, as well as being a standard doctrine of personal computer technology, which is that this kind of distributed computing (a general-purpose computer in nearly every home) would be cheaper than current specialised super computer techniques. What is the basis for that assertion? The equipment itself is currently quite expensive even in the limited forms which are now available, and there is a floor to the cost (unless you know somewhere I can buy a good computer for $1000?) Then there is energy, time, and waste, as well as distribution of software and the cost of software itself.

    I haven't seen any basis for the assumption that all of these can be driven to near zero. If they can be driven way down, then so can the costs of specialised super computing, which could be driven down even further due to economies of scale. A machine that specialises in computing a type of problem is going to process that one thing faster and cheaper than a machine that can process anything. That's true even of theoretical personal computing systems.

    Okay okay, I took some liberties, but your comment basically boils down to "it seems counter intuitive, so it can't be true". Nano skeptics are becoming an increasingly endangered species, mainly because the technology looks so promising. And if you think my analogy above is flawed because processing information is qualitively different to processing materials, then I gently suggest you've not thought about nanotech enough. :-)

    Your comment:
    The equipment itself is currently quite expensive even in the limited forms which are now available (...)

    Is like pointing to any new technology and saying "it's more expensive than the way we do things now, so it always will be more expensive, so it won't work". Do I really need to point out the flaw here?

    No it isn't. Or to use your words - what is the basis for that assertion? A nano-assembler is a nanoassembler, whether it's in a factory or a suburban nano-shop or your basement. Why would we build a nanoasembler that is only able to build one thing?

    Sure, I can imagine a big assembler being able to produce goods faster than a small one (it can literally churn out more per second because it is bigger and can suck in and push out more material), but why significantly cheaper?

    Besides, this misses the point - with widespread nanotech, the very concept of mass-produced identical items is redundant. Why would we do this? Why fill warehouses with product X and then try to sell it, as we do now? Heck, we're moving away from that model even with current technology, why do it that way with nanotech?

    Items could be produced that are individually tailored to the user, and only when needed by the user. These items may cost a little more than an identical item that had been mass-produced, but items tailored to me are not going to be mass-produced, so the comparison is moot.

    As nano-tech becomes possible, cheaper, and widespread, the advantages of just-in-time and just-for-you manufacturing will outweigh the advantages of mass-produced for-everyone, I predict. There are other things to worry about (like how to prevent abuse of cheap widespread nanotech assemblers).
