An Opportunity and a Warning
The next great technological disruption is brewing just out of sight. In small workshops, and faceless office parks, and garages, and basements, revolutionaries are tinkering with machines that can turn digital bits into physical atoms. The machines can download plans for a wrench from the Internet and print out a real, working wrench. Users design their own jewelry, gears, brackets, and toys with a computer program, and use their machines to create real jewelry, gears, brackets, and toys.These machines, generically known as 3D printers, are not imported from the future or the stuff of science fiction. Home versions, imperfect but real, can be had for around $1,000. Every day they get better, and move closer to the mainstream.
In many ways, today’s 3D printing community resembles the personal computing community of the early 1990s. They are a relatively small, technically proficient group, all intrigued by the potential of a great new technology. They tinker with their machines, share their discoveries and creations, and are more focused on what is possible than on what happens after they achieve it. They also benefit from following the personal computer revolution: the connective power of the Internet lets them share, innovate, and communicate much faster than the Homebrew Computer Club could have ever imagined.
The personal computer revolution also casts light on some potential pitfalls that may be in store for the growth of 3D printing. When entrenched interests began to understand just how disruptive personal computing could be (especially massively networked personal computing) they organized in Washington, D.C. to protect their incumbent power. Rallying under the banner of combating piracy and theft, these interests pushed through laws like the Digital Millennium Copyright Act (DMCA) that made it harder to use computers in new and innovative ways. In response, the general public learned once-obscure terms like “fair use” and worked hard to defend their ability to discuss, create, and innovate. Unfortunately, this great public awakening came after Congress had already passed its restrictive laws.
Of course, computers were not the first time that incumbents welcomed new technologies by attempting to restrict them. The arrival of the printing press resulted in new censorship and licensing laws designed to slow the spread of information. The music industry claimed that home taping would destroy it. And, perhaps most memorably, the movie industry compared the VCR to the Boston Strangler preying on a woman home alone.
One of the goals of this whitepaper is to prepare the 3D printing community, and the public at large, before incumbents try to cripple 3D printing with restrictive intellectual property laws. By understanding how intellectual property law relates to 3D printing, and how changes might impact 3D printing’s future, this time we will be ready when incumbents come calling to Congress.
3D Printing
So what is 3D printing? Essentially, a 3D printer is a machine that can turn a blueprint into a physical object. Feed it a design for a wrench, and it produces a physical, working wrench. Scan a coffee mug with a 3D scanner, send the file to the printer, and produce thousands of identical mugs.
While even today there are a number of competing designs for 3D printers, most work in the same general way. Instead of taking a block of material and cutting away until it produces an object, a 3D printer actually builds the object up from tiny bits of material, layer by layer. Among other advantages, this allows a 3D printer to create structures that would be impossible if the designer needed to find a way to insert a cutting tool into a solid block of material. It also allows a 3D printer to form general-purpose material into a wide variety of diverse objects.
Because they create objects by building them up layer-by-layer, 3D printers can create objects with internal, movable parts. Instead of having to print individual parts and have a person assemble them, a 3D printer can print the object already assembled. Of course, a 3D printer can also print individual parts or replacement parts. In fact, some 3D printers can print a substantial number of their own parts, essentially allowing them to self-replicate.
