The Modern Ease of 3D Printing 264
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.'"

I can grow my own food, too, and have done so. What happens when someone copyrights corn's DNA? Monsanto has already patented genetic sequences, and sued farmers who grew food contaminated by Monsanto's GM crap.
Have none of you ever seen Star Trek? We are rapidly heading in that direction. 3D printers are the first step toward the "matter replicator". What happens when these 3D printers are microscopic, printing molecule by molecule or atom by atom?

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.
Big economic boom, but LOTS of violence (Score:4, Interesting)
The biggest economic boom in the history of human kind.
After the information age society is going to move into the replication age and manufacturing is going to shift from the factory back into the home. But the factory infrastructure won't go away - instead it will retool and go big. Mile long ships, mile high buildings, air ships as big as cities that have cities in them are just some of the possibilities. Society will become an invention service society.
One other thing. When invention commoditizes, the patent system will die - Just like the information age forced the commoditisation of information and the death of copyrights, and the industrial revolution forced the commoditisation of labor and the violent death of the plantation system. That is why it is so important THAT WE MUST KILL PATENTS!!!!! Think about it, you can't control information with physical force, but with invention you can. That is why the death of copyrights will involve lots of lawsuits but little physical violence. That won't be the case when killing the patent system. WE MUST KILL PATENTS NOW BECAUSE IF WE DONT THERE WILL BE AWFULL VIOLENCE.

Fasteners are more than just physical objects with a particular shape -- they also depend on the intrinsic material properties. You know, stuff that's only imparted by forging, heat treating, etc. If you don't believe me, try this as an experiment:
Go out into your garage, remove a/the cylinder head cover from your car's engine, remove a cylinder head bolt, heat it cherry red with a blowtorch and put it back. Dollars to doughnuts you'll soon be making a tow-truck assisted trip to your local dealership.

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.

If a burgler gets hold of the key, why the HELL do they need to copy it? If for some reason you think the owner wuold miss it, just replace the house key with any similiar key. They won't know there has been a switch until they get home anyways.
Of course, I don't think any burglers actually uses a key.
