In a 3D printer today, what you can make is limited by the size of the machine. The geometry is external

is the Lego tower is more accurate than the child because the constraint of assembling the bricks lets you detect and correct errors

That's the exponential scaling for working reliably with unreliable parts

Because the parts have a discrete state, it means in joining them you can detect and correct errors

detect and correct state to correct errors to get an exponential reduction in error, which gives you an exponential increase in complexity

The next one is you can join Lego bricks made out of dissimilar materials.

The last one is when you're done with Lego you don't put it in the trash; you take it apart and reuse it because there's state in the materials. In a forest there's no trash; you die and your parts get disassembled and you're made into new stuff. When you make a 3D print or laser cut, when you're done there's recycling attempts but there's no real notion of reusing the parts

The metrology coming from the parts, detecting and correcting errors, joining dissimilar materials, disconnecting, reusing the components

On the very smallest scale, the most exciting work on digital fabrication is the creation of life from scratch. The cell does everything we're talking about. We've had a great collaboration with the Venter Institute on microfluidic machinery to load designer genomes into cells. One step up from that we're developing tabletop chip fab instead of a billion dollar fab, using discrete assembly of blocks of electronic materials to build things like integrated circuits in a tabletop process

a child can make a Lego structure bigger than themself

There's a series of books by David Gingery on how to make a machine shop starting with charcoal and iron ore.

There are twenty amino acids. With those twenty amino acids you make the motors in the molecular muscles in my arm, you make the light sensors in my eye, you make my neural synapses. The way that works is the twenty amino acids don't encode light sensors, or motors. They’re very basic properties like hydrophobic or hydrophilic. With those twenty properties you can make you. In the same sense, digitizing fabrication in the deep sense means that with about twenty building blocks—conducting, insulating, semiconducting, magnetic, dielectric—you can assemble them to create modern technology

By discretizing those three parts we can make all those 500,000 resistors, and with a few more parts everything else.

Now, there's a casual sense, which means a computer controls something to make something, and then there's the deep sense, which is coding the materials. Intellectually, that difference is everything but now I'm going to explain why it doesn't matter.

Then in turn, the next surprise was they weren't there for research, they weren't there for theses, they wanted to make stuff. I taught additive, subtractive, 2D, 3D, form, function, circuits, programming, all of these skills, not to do the research but just using the existing machines today

What they were answering was the killer app for digital fabrication is personal fabrication, meaning, not making what you can buy at Walmart, it’s making what you can't buy in Walmart, making things for a market of one person

The minicomputer industry completely misread PCs

the Altair was life changing for people like me. It was the first computer you could own as an individual. But it was almost useless

It was hard to use but it brought the cost from a million dollars to 100,000 and the size from a warehouse down to a room. What that meant is a workgroup could have one. When a workgroup can have one it meant Ken Thompson and Dennis Ritchie at Bell Labs could invent UNIX—which all modern operating systems descend from—because they didn't have to get permission from a whole corporation to do it

At the PC stage what happened is graphics, storage, processing, IO, all of the subsystems got put in a box

To line that up with fabrication, MIT's 1952 NC Mill is similar to the million-dollar machines in my lab today. These are the mainframes of fab. You need a big organization to have them. The fab labs I'll tell you about are exactly analogous to the cost and complexity of minicomputers. The machines that make machines I'll tell you about are exactly analogous to the cost and complexity of the hobbyist computers. The research we're doing, which is leading up to the Star Trek Replicator, is what leads to the personal fabricator, which is the integrated unit that makes everything

conducting, resistive, insulating.

The fab lab is 2 tons, a $100,000 investment. It fills a few thousand square feet, 3D scanning and printing, precision machining, you can make circuit boards, molding and casting tooling, computer controlled cutting with a knife, with a laser, large format machining, composite layup, surface mount rework, sensors, actuators, embedded programming— technology to make technology.

Ten years you can just plot this doubling. Today, you can send a design to a fab lab and you need ten different machines to turn the data into something. Twenty years from now, all of that will be in one machine that fits in your pocket.

We've been living with this notion that making stuff is an illiberal art for commercial gain and it's not part of the means of expression. But, in fact, today, 3D printing, micromachining, and microcontroller programming are as expressive as painting paintings or writing sonnets but they're not means of expression from the Renaissance. We can finally fix that boundary between art and artisans

You don't go to a fab lab to get access to the machine; you go to the fab lab to make the machine.

Over the next maybe five years we'll be transitioning from buying machines to using machines to make machines. Self-reproducing machines

But they still have consumables like the motors, and they still cut or squirt. Then the interesting transition comes when we go from cutting or printing to assembling and disassembling, to moving to discretely assembled materials

because if anybody can make anything anywhere, it challenges everything

Now, the biggest surprise for me in this is I thought the research was hard. It's leading to how to make the Star Trek Replicator. The insight now is that's an exercise in embodied computation—computation in materials, programming their construction. Lots of work to come, but we know what to do

And that's when you do tabletop chip fab or make airplanes. That's when technical trash goes away because you can disassemble. 

irritated by the maker movement for the failure in mentoring

At something like a Maker Faire, there's hall after hall of repeated reinventions of bad 3D printers and there isn't an easy process to take people from easy to hard

We started a project out of desperation because we kept failing to succeed in working with existing schools, called the Fab Academy. Now, to understand how that works, MIT is based on scarcity. You assume books are scarce, so you have to go there for the library; you assume tools are scarce, so you have to go there for the machines; you assume people are scarce, so you have to go there to see them; and geography is scarce. It adds up to we can fit a few thousand people at a time. For those few thousand people it works really well. But the planet is a few billion people. We're off by six orders of magnitude. 

Next year we're starting a new class with George Church that we've called "How to Grow Almost Anything", which is using fab labs to make bio labs and then teach biotech in it. What we're doing is we're making a new global kind of university

Amusingly, I went to my friends at Educause about accrediting the Fab Academy and they said, "We love it. Where are you located?" And I said, "Yes" and they said, "No." Meaning, "We're all over the earth." And they said, "We have no mechanism. We're not allowed to do that. There's no notion of global accreditation."

Then they said something really helpful: "Pretend."

Once you have a basic set of tools, you can make all the rest of the tools

The way the Fab Academy works, in computing terms, it's like the Internet. Students have peers in workgroups, with mentors, surrounded by machines in labs locally. Then we connect them globally by video and content sharing and all of that. It's an educational network. There are these critical masses of groups locally and then we connect them globally

You still have Microsoft or IBM now but, with all respect to colleagues there, arguably that's the least interesting part of software

To understand the economic and social implications, look at software and look at music to understand what's happening now for fabrication

There's a core set of skills a place like MIT can do but it alone doesn't scale to a billion people. This is taking the social engineering—the character of MIT—but now doing it on this global scale.

Mainframes didn't go away but what opened up is all these tiers of software development that weren't economically viable

If you look at music development, the most interesting stuff in music isn't the big labels, it's all the tiers of music that weren't viable before

You can make music for yourself, for one, ten, 100, 1,000, a million. If you look at the tracks on your device, music is now in tiers that weren't economically viable before. In that example it's a string of data and it becomes a sound. Now in digital fab, it's a string of data and it becomes a thing.

What is work? For the average person—not the people who write for Edge, but just an average person working—you leave home to go to a place you'd rather not be, doing a repetitive operation you'd rather not do, making something designed by somebody you don't know for somebody you'll never see, to get money to then go home and buy something. But what if you could skip that and just make the thing?

It took about ten years for the dot com industry to realize pretty much across the board you don't directly sell the thing. You sell the benefits of the thing

2016 it's in Shenzhen because they're pivoting from mass manufacturing to enabling personal fabrication. We've set Shenzhen as the goal in 2016 for Fab Lab 2.0, which is fab labs making fab labs

To rewind now, you can send something to Shenzhen and mass manufacture it. There's a more interesting thing you can do, which is you go to market by shipping data and you produce it on demand locally, and so you produce it all around the world.

But their point was a lot of printers producing beautiful pages slowly scales if all the pages are different

In the same sense it scales to fabricate globally by doing it locally, not by shipping the products but shipping the data.

It doesn't replace mass manufacturing but mass manufacturing becomes the least interesting stuff where everybody needs the same thing. Instead, what you open up is all these tiers that weren't viable before

There, they consider IKEA the enemy because IKEA defines your taste. Far away they make furniture and flat pack it and send it to a big box store. Great design sense in Barcelona, but 50 percent youth unemployment. A whole generation can't work. Limited jobs. But ships come in from the harbor, you buy stuff in a big box store. And then after a while, trucks go off to a trash dump. They describe it as products in, trash out. Ships come in with products, trash goes out

The bits come and go, globally connected for knowledge, but the atoms stay in the city.

instead of working to get money to buy products made somewhere else, you can make them locally

The biggest tool is a ShotBot 4'x8'x1' NC mill, and you can make beautiful furniture with it. That's what furniture shops use

Anything IKEA makes you can make in a fab lab

it means you can make many of the things you consume directly rather than this very odd remote economic loop

the most interesting part of the DIY phone projects is if you're making a do-it-yourself phone, you can also start to make the things that the phones talk to. You can start to build your own telco providers where the users provide the network rather than spending lots of money on AT&T or whoever

Traditional manufacturing is exactly replaying the script of the computer companies saying, "That's a toy," and it's shining a light to say this creates entirely new economic activity. The new jobs don't come back to the old factories. The ability to make stuff on demand is creating entirely new jobs

To keep playing that forward, when I was in Barcelona for the meeting of all these labs hosted by the city architect and the city, the mayor, Xavier Trias, pushed a button that started a forty-year countdown to self-sufficiency. Not protectionism

I need high-torque efficient motors with integrated lead screws at low cost, custom-produced on demand. All sorts of the building blocks that let us do what I'm doing currently rest on a global supply chain including China's manufacturing agility

The short-term answer is you can't get rid of them because we need them in the supply chain. But the long-term answer is Shenzhen sees the future isn't mass producing for everybody. That's a transitional stage to producing locally

My description of MIT's core competence is it's a safe place for strange people

The real thing ultimately that's driving the fab labs ... the vacuum we filled is a technical one. The means to make stuff. Nobody was providing that. But in turn, the spaces become magnets. Everybody talks about innovation or knowledge economy, but then most things that label that strangle it. The labs become vehicles for bright inventive people who don't fit locally. You can think about the culture of MIT but on this global scale

My allegiance isn't to any one border, it's to the brainpower of the planet and this is building the infrastructure to scale to that brainpower

If you zoom from transistors to microcode to object code to a program, they don't look like each other. But if we take this room and go from city, state, country, it's hierarchical but you preserve geometry

Computation violates geometry unlike most anything else we do

The reason that's so important for the digital fabrication piece is once we build molecular assemblers to build arbitrary systems, you don't want to then paste a few lines of code in it. You need to overlay computation with geometry. It's leading to this complete do-over of computer science

If you take digital fab, plus the real sense of Internet of Things—not the garbled sense—plus the real future of computing aligning hardware and software, it all adds up to this ability to program reality

I run a giant video infrastructure and I have collaborators all over the world that I see more than many of my colleagues at MIT because we're all too busy on campus. The next Silicon Valley is a network, it's not a place. Invention happens in these networks.

When Edwin Land was kicked out of Polaroid, he made the Rowland Institute, which was making an ideal research institute with the best facilities and the best people and they could do whatever they want. But almost nothing came from it because there was no turnover of the gene pool, there was no evolutionary pressure.  

the wrong way to do research, which is to believe there's a privileged set of people that know more than anybody else and to create a barrier that inhibits communication from the inside to the outside

you need evolutionary pressure, you need traffic, you need to be forced to deal with people you don't think you need to encounter, and you need to recognize that to be disruptive it helps to know what people know

For me the hardest thing isn't the research. That's humming along nicely. It's that we're finding we have to build a completely new kind of social order and that social entrepreneurship—figuring out how you live, learn, work, play—is hard and there's a very small set of people who can do that kind of organizational creation.

The consumer electronics company Plantronics, for example, knowing that on any given day 40% of its workforce will be working elsewhere, designed its corporate campus to only 60% capacity

Their joint enterprise, NextSpace, became their first venture into what they call “coworking,” or the creation of “shared collaborative workspaces.”

also nurtures what the authors call “managed serendipity” — ad hoc collaboration between people with diverging but complementary skills

the number of coworking spaces worldwide has shot up from 30 in 2006 to 1,130 in 2011

someone needs to keep an eye on the big picture, to “connect the dots.”

workspaces are designed on a flexible, on-demand and as-needed basis

Coonerty and Neuner found that the most productive collaborations tended to pair highly specialized experts with big-picture thinkers

they were struck by the number of entrepreneurs and freelancers working at coffee shops in the area

Business Talent Group

Clients get the specialized help they need at a cost below that of a full-time employee or traditional consulting firm, and specialists are well compensated and rewarded with flexible schedules and a greater degree of choice about which projects to take.

This has produced a new market dynamic in which the headhunter of yesteryear has been replaced by “talent brokers” who connect highly specialized talent with companies on a project-by-project basis

Matthew Mullenweg, doesn’t have much faith in traditional office buildings or corporate campuses: “I would argue that most offices are full of people not working.”

On the other hand, Mullenweg is a big believer in face-to-face collaboration and brainstorming, and flies his teams all over the globe to do so.

He also set up an informal workspace in San Francisco called the Lounge

Additionally, a 2010 Kauffman-Rand study worried that employer-based health insurance, by discouraging risk-taking, will be an ongoing drag on entrepreneurship

the problem of payroll taxes for freelancers

up to 44% of independent workers encounter difficulty getting paid fully for their work

The chief problem with the paper scrip of the colonial governments was the tendency to print and spend too much.

he Pennsylvania colonists corrected that systemic flaw by establishing a publicly-owned bank, which lent money to farmers and tradespeople at interest

To get the funds into circulation to cover the interest, some extra scrip was printed and spent on government services.

The interest returned to public coffers, to be spent on the common weal.

The result was a system of money and credit that was sustainable without taxes, price inflation or government debt
