An anonymous reader writes "What will it mean when 3D fabricators become cheap and common? A NY Times article explores the ease of copying objects by scanning them with NextEngine scanner and sending them to 3d 'print shops'. The experiments were done with Legos because most of the things around his office were protected by copyright. What will happen to the economy for engineering when we can just download a pirated description of a machine and 'print' it out? 'The world is just beginning to grapple with the implications of this relatively low-cost duplicating method, often called rapid prototyping. Hearing aid companies, for instance, are producing some custom-fitted ear pieces from scanned molds of patients. Custom car companies produce new parts for classic cars or modified parts for hot rods. Consumer product makers create fully functional designs before committing themselves to big production runs.'"

Implications are obvious (Score:5, Insightful)
When you think about it, modern society is moving more and more to the production of "intellectual property" (i.e. an idea as something you can own) rather than the production of physical goods. A modern individual has the capability of mastering their own music and movies, post-processing and distributing their own photographs in both digital and physical form, creating their own PCB-based electronics, designing their own Microprocessors, building their own vehicles (airplanes are a big one!), and many other tasks that used to require massive resources and tens-to-hundreds of emlpoyees.
Each time a task went digital, society was temporarily disrupted while the new technology was integrated. Then life went on, except that society was now capable of greater production than before. The implications of 3D printing technology are the same. The value of goods themselves will be reduced to the cost of initial development. Once that development has been achieved, unlimited copies will be possible. So the average consumer will see a reduction in costs, and the average producer will see an increase in profits.
"Piracy" will continue to be a problem, but it will be just like today. If producers offer a good value for the price, the majority of consumers won't bother with piracy. If producers are dumb enough to resist the change (*cough*I'm looking at you music industry*cough*), then they can expect that piracy will run rampant until they do offer such services.
Then life will go on, but just a bit better than before.

The reason it has happened that way in the past is because creating and replicating audio and video are relatively easy once they are digitized. The sensory data (sound saves and light waves) lend themselves well for digital reproduction at close to perfect quality. Duplication can be done perfectly, with no loss in transmission.
That is not the case with physical reproduction, and I doubt will be for some time. These 3d scanners are good for only what their ads say: prototyping. There will not be a day when you will be able to scan copy and duplicate even a nut or a bolt in your garage anywhere near as cheaply as it can be done en masse at a production plant simply because the mould, tools and materials are too expensive on a small scale to be feasible. Now I know about the "never say never" line in technology, but I'm going to go out on a limb here and say that while the productive capacity of the home user will scale up, you will never get to the point where manufacturers of physical items will be squeezed out the way manufacturers of virtual goods (music, movies etc) have been. There's a fundamental difference between copying Britney Spears' latest warblings and copying a Ferrari.

I agree and yet I disagree at the same time. I agree that scanning is an imperfect process that isn't likely to improve sufficiently in the next few decades. However, when a modern engineer is developing a part, does he still use a pen and paper to design the diagram? Of course not! The object is designed in detail in a CAD program. Those CAD drawings are then used in manufacturing a mold to spec.
Now consider for a moment, what happens when you take that 3D model and feed it into a 3D Printer? In theory, at least, the printer will be able to reproduce the object with perfect quality. In reality, the printer will be limited by its design (as most manufacturing methods are), possibly requiring the 3D model to be tweaked for the printer. However, most parts are created with similar limitations in mind (e.g. a plastic part is likely to be in two pieces with open ends that fit together) making the models very easy to transfer over to 3D printing.
Now I don't disagree that there will continue to be significant differences between what someone can manufacture in the home and what can be manufactured in an industrial environment, but the gap will close. It has always closed and will continue to close in every industry in existence. Today, we can develop high-quality prints of photos from digital negatives with an in-store machine. We can print and bind nearly any book with an in-store machine. We can press a CD or DVD with a color label with a simple machine. We can quickly produce a custom PCB board with a simple machine. These things have come down to the consumer scale, even if machines that can do even better exist.
The same will happen with 3D printers. You're going to have everything from a home machine capable of printing toys, widgets, and useful household items; you're going have large machines capable of printing houses and ship hulls; and you're going to have everything in-between. I for one can't wait for the day when I can print my own customized CD shelf or cup holder.

Actually, you can create it in any material supported by the printer. As the 3D Printers evolve, they're beginning to print other materials besides plastic. For example, that 3D House Printing story a few weeks ago was not done out of plastics and resins. It was done out of concrete materials designed to work well with the printer. Unsurprisingly, there are also metal printers [bathsheba.com] available for many tasks. You only hear about plastic materials so much because they're easy to work with, cheap to produce, and are very versatile in creating different objects.

Humans are not wired to behave the way in which you describe. People get bored doing nothing. All you have to look at for am example of this is the number of people who are perfectly financially secure who return to work anyway, because they are bored with retirement.
People's brains needs stimulus. Even if you consider games and other entertainment - if no one makes new entertainment, then the current supply will be quickly exhausted, and the populace will become bored again. At that point, they will start doing creative things they enjoy.
And none of this would "stifle innovation". What about all the dreamers who want to explore space and beyond, or to understand how the physical universe works in more detail? These people will always continue research and innovation - the difference is they will be able to innovate HOW they want and WHEN they want, without being constrained to rules of artificial scarcity or need for essentials, since all their materials would be "free" to them via their replicator.
Really, replicator instantly solve a vast amount of global issues. You no longer have hunger. You no longer have theft since there is no value in stolen objects. You no longer have a "drug problem" since everyone who wants rugs can replicate themselves into a stupor without harming anyone else, and darwinian processes will quickly weed people with those addictive tenancies into oblivion. Likewise, there will be little need for war since there are no resources to argue over, and even if there were you would be assured of mutual destruction since anyone can replicate any weapons they can imagine.

This has been changing. Modern printers use much stronger materials based on resins similar to those used in Legos. So if you need a plastic part, you should be able to print one of reasonable strength. For example, I could see a huge market for toys on demand much in the way that books are slowly moving to print on demand.
It's fairly rare to be able to create a moveable part in a single mold. Usually, you create a variety of parts, then assemble them. When this starts to catch on with consumers, I imagine you'll first see products coming in many parts with "some assembly required". Later revisions of the technology might include robotic assemblers that construct devices in a manner similar to how PODs are now able to print and bind nearly any book. While the precise assembly options may not be comprehensive, model developers will know the limitations of the machines and attempt to modify their models so that they're more easily assembled by the robotics.
Also, there is an issue of scale that needs to be considered. There's nothing preventing a larger 3D printer from printing in concretes or metals. In fact, there was a story here a few weeks ago about a 3D printer that could construct a house in a few days. But why stop there? Ship hulls, car bodies, air foils, and many other items which are so large as to be difficult to mold could conceivably be printed instead. In many cases it may even be advantageous, as the part will be producable as a single object with no seams or rivets. This can potentially strengthen the object overall. Chemical agents can also be used to treat the object for better strength and endurance.
Obviously, the technology is just getting started. But it has been making great strides in the short time it's been available. Give it a decade or two more and the necessary material injection techniques and production methods will get most of the bugs worked out.

Some of the other systems from companies like Dimension or Stratasys use stronger plastics but can't produce multicolored items.
Some can produce fully working items right from the printer . They deposit two types of material: one soluable and one insoluable. After the thing is printed, you wash away the soluable stuff and the gaps open up. It's amazing. I've played with fully adjustable crescent wrenches that are built with almost the same precision as the ones from Sears. The plastic isn't as durable as metal, but you can certainly build things with the wrench. I'm told one of the cooler demonstration items is a bicycle chain that's fully assembled after the wash.
In some sense, these pre-assembled machines are better than traditional manufacturing techniques because you can build working items inside of sealed shells. There's no ship-in-a-bottle paradox because everything is built from the bottom up.

Rapid prototyping/3d fabrication is becoming cheaper. You know what that will allow, more than anything? It'll allow competition by the little guy, to produce their own items and test them without the expense of the full production process for a lot of different things. That will mean that skill at design and meeting the real needs of customers will become more attainable by more people, and overall costs will go down.
It's like the commoditization of computer hardware that happened in the late 80's for the consumer sector, and late 90's for the mid-range server sector, and what's happening to the software sector right now. Who's allowed to feasibly compete for customer's money will become a more level playing field, which will cut into the biggest producers profits somewhat, as more people compete, but the big players that adopt the technology will ultimately win out over the big players who don't, and the little guys will generally stay little, with either have a few breakthrough big boom companies, or the few big growers get squashed/eaten if enough of the big players catch a clue fast enough. The latter happened with the hardware market, the former is happening with the software market (google).

He then argued, that Communism — which Soviet People were busily building, supposedly, while living under the less perfect Socialism — will become possible, when the means of production evolve even further, to the point where Communism's principle of distribution of goods: "From each by their ability, to each by their needs," — will come into being.
Ironically, it is the Capitalist societies, that are quickly approaching that benchmark. More and more things are given out free or for next to nothing to more and more people. Officially "poor" people have cars and TV-sets, and are entitled to substantial give-aways of food...
