An interesting article in The Economist:

As an expert on intellectual property, Mr Weinberg has produced a white paper that documents the likely course of 3D-printing’s development — and how the technology could be affected by patent and copyright law. He is far from sanguine about its prospects. His main fear is that the fledgling technology could have its wings clipped by traditional manufacturers, who will doubtless view it as a threat to their livelihoods, and do all in their powers to nobble it. Because of a 3D printer’s ability to make perfect replicas, they will probably try to brand it a piracy machine.

[. . .]

As with any disruptive technology — from the printing press to the photocopier and the personal computer — 3D printing is going to upset existing manufacturers, who are bound to see it as a threat to their traditional way of doing business. And as 3D printing proliferates, the incumbents will almost certainly demand protection from upstarts with low cost of entry to their markets.

Manufacturers are likely to behave much like the record industry did when its own business model — based on selling pricey CD albums that few music fans wanted instead of cheap single tracks they craved — came under attack from file-swapping technology and MP3 software. The manufacturers’ most likely recourse will be to embrace copyright, rather than patent, law, because many of their patents will have expired. Patents apply for only 20 years while copyright continues for 70 years after the creator’s death.

[. . .]

In that, the record industry was remarkably successful. Today, websites and ISPs have to block or remove infringing material whenever they receive a DMCA takedown notice from a copyright holder — something that happens more often than actually justified. Google reckons that more than a third of the DMCA notices it has received over the years have turned out to be bogus copyright claims. Over a half were from companies trying to restrict competing businesses rather than law-breakers.

Rallying under the banner of piracy and theft, established manufacturers could likewise seek to get the doctrine of “contributory infringement” included in some expanded object-copyright law as a way of crippling the personal-manufacturing movement before it eats their lunch. Being free to sue websites that host 3D design files as “havens of piracy” would save them the time and money of having to prosecute thousands of individuals with a 3D printer churning out copies at home.
