One of the most common questions I get about 3D printing from reporters is “what is going to happen when companies discover this and start freaking out?”  More specifically, what happens when an industry has a “Napster moment” and decides that these crazy 3D printers are destroying their business model?

My usual answer is that I hope that the industry (whatever it is) learns from history and does not simply repeat it.  When the internet became widely available and Napser showed just how easy it was to distribute music online, the music industry’s first reaction was to sue.  The industry dedicated time, money, and effort to trying to turn back innovation and protect a business model that was suddenly outdated.  It took years, and essentially being tricked by Apple, before the industry started dedicating some of that time, money, and effort to monetizing the internet. 

Hopefully, the first industry disrupted by 3D printing skips phase one (sue everyone and pretend the technology does not exist) and jumps right to phase two (figure out how to turn this new technology into a way to make money).  Encouragingly, there is some evidence that this is actually happening.

The first example of this was Teenage Engineering, a company that makes synthesizers.  These synthesizers have small plastic parts, and sometimes those parts break.  Unfortunately, it was costing their customers a lot of money to replace these small plastic parts because shipping them was expensive.  Teenage Engineering decided to put the CAD files for the parts up on its site so that its customers could just print their own.

Today, we have a similar example of an even larger company viewing 3D printing as an opportunity, not a threat.  Nokia announced that it was releasing CAD files for the back shells of one of its phones.  This allows consumers to create their own customized back plates for their phones and print them out on their own.

Simply put, this is great news.  When confronted with widespread access to 3D printing, both of these companies are asking “how can I use this to my advantage?” not “how can I sue to stop this?”  Going forward, hopefully more companies decide to learn from history and follow these examples.

The general reaction to the idea of expanding DRM to 3D printing has been, encouragingly, negative.  DRM has completely failed to slow the supply of unauthorized copies of music, movies, and books online.  At the same time it has succeeded in frustrating perfectly legitimate uses of copyrighted content.  There is no reason to think that either of those outcomes would be different if DRM was applied to 3D printing.  However, there could be a way to apply DRM-like techniques to 3D printing in a positive, consumer-friendly way.

Two distinct categories of DRM

Broadly speaking, there are two types of DRM.  The first is DRM that focuses on the needs of sellers.  This is DRM that is generally associated with music, movies, and books, and basically treats all users like they are criminals a click away from committing copyright infringement.  The second is DRM that focuses on the needs of the buyers.  Truth be told, this is not really DRM at all.  Instead, this is a bundle of techniques that allow users to trace the origin of a particular good.  It has more in common with trademark than copyright, and could also be thought of as digital verification technology (DVT).

Pro-seller DRM, the kind that does not work

DRM, as a stand-alone protection for copyright-protected works, is fatally flawed.  It assumes that as long as an average user cannot circumvent copy protection, no unauthorized copies will be made.  However, because the protected works are digital, an average user does not have to be able to circumvent copy protection.  As soon as one not-so-average user breaks the digital lock and creates an unprotected copy, that copy is available to everyone.  Average users do not need to be able to break the lock themselves – they can just find the unprotected copy made by the person who broke it for them.

Because of this flaw, DRM does not actually provide a benefit to creators.  However, it does impose a cost on users.  DRM can cause platform lock-in, making it hard to transfer things like movies or books between devices.  It can also create a barrier to otherwise legitimate uses – a problem that the Copyright Office tries but fails to address every three years.  

The fundamental weakness of pro-seller DRM is that consumers have no real interest in maintaining its integrity.  A legitimate purchaser who only wants to use media within the scope of DRM-allowed parameters never really comes into contact with it.  A legitimate purchaser who wants to use media in a way that is legal but exceeds the DRM parameters sees it as a nuisance (at best).  An illegitimate copier circumvents the DRM herself or simply finds a copy that has already been separated from DRM.  None of these users has an incentive to support the integrity of the DRM scheme.  

Pro-Consumer DRM, a kind that could work

Contrast this traditional role for DRM with a slightly different application – digital verification technology (DVT).  The role of DVT is not to prevent unauthorized copying on behalf of sellers.  Instead, DVT is designed to assure consumers that the file they have will produce the object they want.

While this type of verification could be used in the digital world (and is used in the form ofchecksums), in general it is not necessary.  A digital copy is, by definition, an exact copy.  A copy of a movie downloaded from iTunes can be copied identically tens, hundreds, thousands of times.  For an end user, the original authorized copy will produce exactly the same movie as the thousandth copy.

The transition from digital to physical makes copying less reliable.  The same digital file can produce meaningfully different physical objects when printed by different types of 3D printers. Even two identical 3D printers will produce slightly different physical objects.

Sometimes these differences will not matter to a consumer.  But other times they will.  It is not hard to imagine that someone printing a functional part for an industrial machine would be interested in knowing that the source file is the file that will produce the correct object on the 3D printer being used, not just a reasonable approximation of that file. 

This is where DVT comes in.  Not every consumer will be interested in using DVT for every print.  Someone buying “designer” sunglasses from a table set up on the sidewalk may not be interested in verifying where the sunglasses were really made or that they were designed correctly.  Similarly, someone downloading a file for designer sunglasses from some dark corner of the internet may not care about the file’s source. 

However, there are plenty of instances where consumers will care.  After all, consumers care about being able to verify that their medicine really came from a factory that was using active ingredients.  They could also care that someone who knew what they were doing designed the latch holding the hood of their car shut – or the bracket supporting the shelf over their head.  This does not mean that the file the consumer is using is an authorized copy.  Rather, it means that the file for the object is actually a copy of the “real” file – not just a file that has been reversed engineered with an unknown degree of accuracy. 

Every person using a 3D printer may not want, or care, to implement this technology.  But it is likely that many will.   Unlike DRM, this consumer interest means that DVT might actually work.  Instead of assuming the end user is a criminal, DVT enlists the consumer as a willing partner.  

A Useful Path Forward

Work is already being done on this type of technology.  For example, Professors Daniel G. Aliaga and Mikhail J. Atallah at Purdue University have been working on embedding signatures in physical objects.  This information could be ignored by an uninterested consumer, but could be highly valuable to a consumer searching for assurances that the file they are using came from a trusted designer and printer.

Of course, there are also individuals and companies discussing more traditional DRM in the context of 3D printing.  They are free to continue what will likely be a wasted effort, at least unless they begin trying to require all 3D printers to implement it.

Going forward, hopefully innovators will focus on ways to give consumers who want it confidence in the source of their digital files and, ultimately, physical goods.  As 3D printing becomes more prominent and 3D printed goods become more common, quality will be critical to convincing the public that the technology is more than a fad.  Allocating development resources in this way, instead of in a futile attempt to prevent unauthorized copies, will be much more beneficial in the long term.

Internet Service Providers (ISPs) regularly insist that data caps are a legitimate tool to ease congestion on their networks and an effective way to signal value to consumers. But, as we haveargued, data caps do not resolve congestion, are confusing to consumers, and lend themselves to unfair and anticompetitive behavior. 

In light of this disagreement, it is a promising sign that a recent study published by the National Cable & Telecommunications Association (NCTA) and co-authored by Steven S. Wildman, the new Chief Economist of the FCC, moves beyond some of the previous rhetoric and takes a significant step towards focusing the debate on real areas of conflict.  

Unfortunately, it stops short of recognizing a critical distinction in understanding the heart of the disagreement. Let’s take a look:

Congestion is not the Issue

On Friday, Rep. Steve Israel reportedly invoked 3D printing to illustrate his concerns about undetectable plastic firearms.  This may represent the first time that a lawmaker has explicitly linked 3D printing with a perceived threat to society.  Hopefully, Rep. Israel recognizes there is no such thing as a 3D printing-specific solution to the problem of plastic guns.

Let’s be clear about one thing: nobody wants people sneaking guns onto airplanes or into other areas protected by metal detectors.  And we have all seen In the Line of Fire enough times to understand that plastic guns can be smuggled into places that metal guns might never see.  But any attempt to address these concerns should focus on plastic guns, not 3D printers.

Fundamentally, this is because there is not a 3D printing-focused solution to this issue.  3D printers work by turning a digital file into a physical object.  That physical object can be made out of any number of materials.  While a digital file may work better or worse with some materials than others, nothing about the file is inherently tied to a given material. 

This versatility is one of the characteristics that makes 3D printing so powerful.  Even without a 3D printer of your own, you can buy Bathsheba Grossman’s Gyroid sculpture in plastic.  Or steel.  Or silver.  Or glass.  Or sandstone.  You could travel to a Dutch Staples and print it in paper.  You could make nice with Hod Lipson and Jeff Lipton at Cornell and print it in cheese or batter.  That is just as true for a gun file.  The difference between a detectable and undetectable 3D printed gun lies in the printing.  Not the file.

And that file is a digital file just like any other.  For all intents and purposes, once it exists in one place online it exists every place online.  Congress cannot make a file for a 3D printed gun disappear off the internet any more than it can do so for a pirated version of The Avengers.

Finally, there is no way to stop a 3D printer from printing a particular type of thing.  As we havewritten before, a 3D printer is a general purpose machine that can be used to make just about anything – both good anythings and bad anythings. Printers do not run software that checks with a central approved database before they print something out.  In fact, because 3D printerscan print themselves, there is not even a central database that keeps track of all of the 3D printers in the world.

That is why, as a general rule, we do not focus on tools when we are trying to solve a policy problem.  We would never try and stop bombs by passing a law controlling wires or try and stop hacking by passing a law controlling the use of command line tools. 

Instead, we focus on behaviors.  It is illegal to blow something up with a bomb no matter how it was made.  It is illegal to hack into protected database no matter how you do it.   If you believe that people should not be able to carry plastic guns, make it illegal to possess plastic guns.  No one is worried about printing undetectable guns with a 3D printer per se.  They are worried about undetectable guns. 

It is probably a good thing that Rep. Israel is pursuing a conversation about plastic guns, and these days invoking 3D printing is a good way to bring attention to an issue.  But in crafting a solution, hopefully Rep. Israel will focus on the problem – not just a high-profile tool.  After all, if Congress passed a law banning undetectable guns in 1988, and John Malkovitch’s Mitch Leary was creating plastic guns in 1993, eliminating 3D printing from the equation is not going to solve any problems.  But it could cripple the growth of legitimate applications for this promising technology.

While you were preparing to get your Thanksgiving on last week, news broke that one of the oldest and largest 3D printing companies, 3D Systems, was suing one of the newest, Formlabs, for patent infringement.  Besides the obvious question (is Formlabs actually infringing?), the suit raises two other interesting questions: what does it mean when an established 3D printing company sues an upstart for patent infringement?  And why did 3D Systems decide to sue Kickstarter as well?

First, a bit of background 

3D printing has existed since the mid-1980s.  However, it was not until 2007 that Professor Adrian Bowyer created the RepRap – the grandfather of almost all “home” 3D printers available today.  Why the delay?  Largely patents.  

Once the first 3D printing patents began to expire in 2007, the community quickly embraced, and rapidly improved upon, the 20-year old technology.  In just a few years a number of companies were selling their own version of a home 3D printer.  

While each of these printers are unique, almost all of them worked in essentially the same way – they built objects up layer by layer from melted plastic.  This was because everyone in the market was building off of the same expired patents (and was limited by the same existing patents).

That was one of the things that made Formlabs’ FORM 1 printer so interesting.  It had higher resolution and used a fundamentally different technology than most existing printers.  While it was no doubt an impressive feat of  engineering, the real achievement appeared to be a feat of lawyering – how had everyone missed this hole in the existing patent wall?

3D Systems Suing Formlabs

Although there is a great deal of interesting discussion about problems with the patent system (especially software patents) and with the relationship between patents and open source 3D printers, those concerns are not necessarily relevant here. I will not pretend to be an engineer nor a patent attorney (and will update this post when I am corrected in my interpretation), but the patent in question seems to be reasonably close to what people might think of as a “regular” (non-controversial type) patent involving materials science.  The larger debate around patent reform rarely focuses on these types of patents, and no one can accuse 3D Systems of being a non-practicing entity (also known as a troll) or of hiding the fact that they own many patents related to 3D printing.

Similarly, the larger openness question does not directly apply to this case.  Formlabs may not have patented its technology, but it has not embraced openness either.  From an openness standpoint, this is essentially one closed company suing another.

All of this means that 3D Systems’ decision to sue Formlabs should not automatically make it a bad actor.  If they had a valid patent and Formlabs was infringing upon it, they have every right to sue. Furthermore, if Formlabs was able to beat all of its (consumer-grade) competitors by ignoring the patent that was keeping everyone else away from a better 3D printing technology, they should not necessarily be rewarded.
