You're listening to Part Time Genius, a production of Kaleidoscope and iHeartRadio.
Guess what Will? What's that Mango?
So I was reading about three D printing this week and I realized I've been thinking of it as a new technology when really it's been around for nearly half a century.
Oh wow, I actually had no idea I went back that far. Yeah.
So, the Japanese researcher Hideo Kodoma submitted the world's first patent for a three D printer in nineteen eighty one, and two years later, American inventor Chuck Hall created the first working prototype. And before you ask, yes, we do know what the first object you prayed was. It was a little plastic eyewash cup. You know, I don't know what I was expecting you to say, but that definitely was not it. And what even is an eye wash cup?
It is a tiny cup with a curved rim to fit around an eyeball, so if you get a piece of dust in your eye, you can fill the cup with water and flush it out.
Like, was this a recurring problem for Hull?
Yeah? His eyes were notoriously dirty dirty.
Yeah.
No, I'm actually not sure why he chose an eye wash cup, And I know it sounds like a random thing to make as the first three D printed object, but to be fair, that would probably be the case no.
Matter what he picked.
You know, it's still impressive that he was three D printing over forty years ago. Like, I feel like I only heard about.
This in the last I don't know, at least within the last decade, right.
Yeah, So it took a lot of years of fine tuning to make three D printers affordable and simple enough for the consumer market. But now that we have, it's easy to see what guys like Codoma and Hall knew the whole time, which is that three D printing is truly revolutionary. It's transforming almost anything you can think of, from construction to food prep to aerospace engineering. And of course there's an incredible creative community that's developed around it too.
And the reason we're thinking about all of this is that one of our listeners asked us to do an episode about three D printing, and we love an intriguing request, and we really wanted to know how people make things out of thin air or thin plastics.
So let's dive in.
Hey, their podcast listeners welcome to part time genius. I'm Will Pearson and as always I'm joined by my good friend Mangeshot Ticketer and on the other side of the soundproof glass printing out the same sheet of paper for what must be the hundredth time now, not exaggerating. He just keeps printing. That's our friends and producer Dylan Fagan. He just keeps loading and reloading the same sheet. He's wasting a fortune on ink. But do you know what's going on with this mango?
Yeah, he said he felt left out about not having a three D printer, so he's using a two D printer to print out a picture of a three D printer.
Got it.
I guess the idea is if he prints it on the same page enough times, eventually the ink would build up and the picture will be three dimensional.
You know, that's an interesting idea.
I'm not sure that'll work, but you've got to admire this guy's ingenuity always. And weirdly enough, that is basically how a three D printer works. Like following instructions from a digital file, the printer gradually builds an object by adding one layer of material on top of another on top of another, and the problem here is that you need to use something a bit sturdier than liquid ink, and most.
People make three D printed objects out of plastic, right.
Yeah, but plastic is really just the tip of the iceberg. So industrial three D printers can handle all kinds of multiple materials, including ceramic, wood, fiber, paper, glass, even edible proteins.
Actually, oh, that's right, edible proteins. So will When was the first time you heard about three D printers?
You know, I feel like this probably goes back to the days when we were working a little bit more closely with the house Stuff Works team.
Even thinking back to.
You know, Marshall Brain who founded so many years ago, and remembering him talking about this, it might have been a little more than a decade ago. It was probably like fourteen fifteen years ago.
How about you.
Yeah, I think about the same.
I remember.
Around twenty thirteen or twenty fourteen. The first time I heard something interesting with three D printers was before this party. They had all these attendees send in photos and then as a party favor, they were handed a three D printed pez dispenser of their own face.
Oh no, cool. I remember thinking that was just really weird and fun.
At the time. But the thing that really blew me away was when they started talking about those three D printed foods like pizzas and cookies, Like if you could print a meal at home, that just seems so futuristic to me.
Yeah.
The London pop up you're talking about was called food Inc. And even though it was only open for three days back in twenty sixteen, it made an impression because it was many people's introduction to the idea of printable meals. Now, in the years since, lots of other companies have tinkered with similar concepts, including a finished research center that's developing
vending machines that print snacks huh. And this Israeli food tech company called Stakeholder Foods that's specializing in three D printed meat, which sounds so weird.
How do you print meat?
It's you know, you can load just about anything into a three D printing syringe if it's a smooth consistency. So Research as a Columbia did it with chicken puree and ran it through a system that cooked it while it was printing. But in the case of Stakeholder Foods, the three D printed meat is actually plant based. They make three D printed whitefish filets and steak using a mixture of water, soy and pea protein, also oil and
a few other ingredients in there. And so these faux meats have different textures, so the outside gets crisp when you cook it, and the steaks even come with lines of three D printed fat.
That sounds so bizarre, but I guess it's fine as long as it tastes good, right, So.
The bad news about that. There was a Wired journalist named Matt Reynolds and he did this taste test last year and he described the Stakeholder meats as being quote technically food, but ad they quote had all the joy of licking a catering catalog. So you know, delicious food might be an area where three D printing still has a long way to go.
So you know, you mentioned that London restaurant and how it was many people's first introduction to three D printed foods, but Gabe tipped me off that Star Trek had a machine called the Replicator that could produce anything on demand, so basically a three D printer, and the crew mostly used it to make food and drinks, which is pretty cool, But I guess, as you were describing, we're not quite there yet no.
But I am glad you brought up the connection between three D printing and science fiction, because this idea has been a recurring theme in sci fi stories for some time now, and some actually predate Charles Hol's Big Brain break through in the early eighties. In fact, the earliest known reference to three D printing was in a short story by American novelist Murray Leinster. It was called Things
Passed By. It was published in nineteen forty five, about four decades before hle printed his Eye wash Cup, and it describes a machine that uses plastic to create three dimensional objects from two dimensional drawings.
And I'm sure he described printing an eye wash cup.
I kind of wish.
But now in this story, the tech is used to build spaceships, and the process is incredibly similar to how three D printers would eventually work. So Linser describes the liquid plastic flowing through a hose connected to this moving arm that gradually deposits blobs of plastic in shapes determined by the drawing. Now, he likened it to an insect spinning a cocoon, which I kind of actually love that description, and.
It's kind of accurate, right, Like, so Obviously this stuff is rooted in sci fi. But walk me through some of the real world applications of three D printing, Like why were so many people excited about it?
The since people are so enamored with three D printing is because of its ability to help us prototype. Take jewelry for instance, Like, Historically, it's been a very time consuming process. So after coming up with an idea for a piece of jewelry, the designer had to hand carve a model from clay kind of sculpt out the details there. Then they'd use that model to create a mold, and then finally pour molten metal into the mold to create this finished piece. That could take days or weeks or
even longer depending on how sophisticated it was. But now jewelers can actually design new pieces digitally using CAD software and three D print them as wax or like a resin model, and then they can go from design to prototype or even a finished product in just a few hours. These days, about ninety percent of all jewelry sold in the US has been made with some degree of three D printing.
So what definitely do you mean by some degree?
Well, in addition to prototyping, designers can skip the mold making stage and just print metal jewelry directly. This has done through a process called laser centering, which also kind of sounds like something they'd have in Star Trek.
Yeah, star Trek, the next generation of jewelers, I'm not sure.
Yeah, well, let me tell you what centering actually is. So you spread this thin layer of metal powder on a bed and then a laser fuses it together. Then you spread a thin layer of powder on top of that, and then laser it again, building layer by layer, and after each sweep of the laser you add a fresh layer of powder on top, and it keeps building until the object's finished.
That's obviously incredible. But are we just using this for jewelry or are there other applications?
No, it's just jewelry.
People have not figured out anything but jewelry now. Definitely other applications, like all kinds of industries are using laser centering. For example, car manufacturers use it to prototype hardware. It's even used for some finished products like aerospace components, medical hardware, electronics, like it's pretty long list.
Well, speaking of medical hardware, one thing that blew me away is that almost every hearing aid on the market these days is three D printed.
Oh wow.
Yeah, people use have a hard time finding hearing aids that match the contours of their ear canals, and that's because hearing aids only came in a few standard sizes, so if one of them didn't fit, you just had to make do with something that was too loose or too snug. But now with three D printing, audiologists can take a digital scan of a patient's ear and create
a perfectly customized hearing aid just for them. And you can find these advances all over the medical field, like whether it's with three D printed surgical tools, implants, or even artificial limbs.
That is really so cool. We've come a long way from that one little eye wash cup.
And I think the coolest fact about this technology is that it's not just limited to stuff like making a custom phone case or improving an industrial production process. It's actually improving and saving lives every day in ways that most of us don't even realize.
Indeed, and you know, we have some really fascinating examples of that coming up. But first, let's take a quick break. You're listening to part Time Genius and we're talking about the world of three D printing. All right, mego, so tell me more about how this technology is actually saving lives these days.
Yeah, it's not just saving any lives, it's saving turtle lives.
Okay, I'm intrigued, tell me more so.
Back in twenty sixteen, a group of animal rescuers in Brazil came across a tortoise that had lost eighty five percent of its shell in a brush fire. The tortoise, which the team named Freddy, didn't have a high chance of survival without a shell, so after treating the little guy for his burns, they decided to build him a new one. First, they built a three D model of a shell based on pictures of Freddy and other tortoises.
Then they printed out in four interlocking pieces, and the all white plastic shell was assembled in gluten place around Freddy's body, and as a final touch, the team hand painted it to make sure it looked like his old shell.
That's heartwarming and pretty amazing science. Yeah yeah, I love the story. And it's not just Freddy. Other turtles have been saved with three D printing as well. For example, in places like Arizona and Florida, hundreds of turtles a year are injured by cars and left with broken shells, and a turtle with a hole in its shell is highly vulnerable to infection and even spinal damage. In the past, custom prosthesis for this type of injury could cost hundreds
of dollars or more. But now it's actually possible to scan the broken pieces of a turtle shell, create a three D model, and print out new ones for as little as I don't know, like twenty bucks, oh wow. And similar techniques have been used to restore bird bills, reattach alligator tails, and replace the missing limbs of cats, dogs, and other species including humans.
It really is pretty incredible.
And actually, you know, you talked about how three D printing has brought the cost of animal prosthesis down, and that's actually also true for humans. So high end bionic arms canst upwards of one hundred thousand dollars, which means that less than one percent of the adult amputee population can actually afford to buy one.
I can't even imagine. But is that because the components are so expensive or why is not?
I mean, that's part of it, But the other issue is that the production process is just super complicated like, different components get made in separate factories by different companies, then yet another company assembles them. So all these manufacturing costs and markups get factored into that final price. But three D printing can streamline this process by cutting out the middleman. Now a company can scan print and as symbol a bionic arm with a single facility.
And so how much cheaper does that actually become?
You know, there's some variables here, like the size and complexity of the arm, and of course what kind of insurance you have. But if you look at the two leading companies in the field, you've got Unlimited Tomorrow and Open Bionics. Their prosthetic arms cost five to ten times less than a traditional manufactured one. And this is especially important when you consider the difficulty for young amputees because kids outgrow these prosthesis and you know, they need bigger ones as they get older.
You know, I never actually thought about that, Like I feel like I get stressed out watching how fast my kids outgrow their shoes. Yeah, you can't even imagine for amputees.
No, it's very true, and the lower cost isn't actually the only advantage here, because when all the components are three D printed. There's also more opportunity for customization. For instance, open i Biotics calls their limb the Hero Arm, and it has all these cool magnetic panels that you can pop off and on. They come in different colors and textures.
You can coordinate them with your outfits. They even make these panel sets based on licensed characters, so you can trick out your arm to look like like Iron Man's Gauntlet or Adroid from Star Wars.
Like, there's so many cool possibilities.
I'm sure that is great for kids, but I bet there are plenty of adults who would also love a superhero, are right.
I mean it's so cool you get to cosplay at work and nobody can complain because like, that's just.
Your arm, you know.
And I know that decorating your arm might sound frivolous, but I actually found this quote from one of open Bionics founders, Samantha Pain, and she pointed out that having a prosthetic limb that purposefully looks artificial is kind of subversive and fun. So, as she puts it, quote, a
generation ago, as a society, we valued conformity. Everyone wanted to look the same, and that's why you saw a lot of prosthetic arms that tried to blend in that tried to look human, but as engineers, we couldn't quite get the look right. So it's really cool that as time moved on, we began to celebrate individualism and self expression.
Yeah, that feels really liberating. Of course, while getting creative seems smart for three D printing for your prosthetic arms, when it comes to three D printing internal organs, it helps to get as close to the real deal as possible. And that's why bioinc is so important, because while your body might not accept a bladder made of artificial material like plastic or carbon fiber, if you print one using bioinc, the chances are it'll get along just fine with your interiors.
So what is bioinc.
It is basically a mixture of a special kind of eletin and the cultured cells needed to create living tissue. And this gets a little technical here, but let's say someone's missing an ear and their doctor wants to print a functional replacement, which is a thing they can actually do. The first step is to harvest stem cells from the patient. These are undifferentiated cells, meaning they don't have a specific purpose yet, and they can turn into other types of
cells like tissue or bone. You can kind of think of them like a blank template of the human body. So the doctors would manipulate the genes in these stem cells so they develop into cells that do have a specific purpose. In this case, that would be functions related to hearing and balance. Then you mix them with gelatin and some other high end biomaterials to create something called bioinc and you load that into a three D printer
and voila instant ear. And the best part is, since it's made from the patient's own cells, the odds of the body rejecting it are much much lower compared to a donor transplant. This actually might blow your mind, but the first three D printed organ was transplanted into human way back in nineteen ninety nine, which is the same year a few other important things happened like SpongeBob SquarePants debuted and Napster launched.
So three equally important advanced mess.
But that's also the year that scientists at the wake Forest Institute for Regenerative Medicine created a new bladder using cells from a patient, and they successfully implanted it in the same person without any complications. The procedure has actually been repeated about a dozen times since then, and all of those three D printed bladders, even the ones from a couple decades back, are still fully functioning today. Wow.
You know, I'm thinking, as you're talking about this, about all the people waiting on transplant lists for organs, So can we do this for any organ.
So as the technology stands, it's easiest to bioprint flat or hollow organs. So you think about bladders, things like skin, ears, wind pipes, right, these are things that have been successfully transplanted already, but anything more complex and that is still off the table. So scientists have made some headway in recent years by printing small scale, functional replicas of hearts, kidneys, even brains, and the hope is that in the next few decades they'll be able to make them full size.
You know, maybe I think we've proven conclusively that three D printing can can really help humans and animals, especially tortoises with the story you were telling there, And that's all great, But like any technology, it's a tool that can also do harm unfortunately, So we probably should take a moment to recognize what may be the darkest side of three D printing, and that is ghost guns.
So I know this is the thing that people have been worried about, that you can make three D printed guns that can actually fire real bullets. But why exactly are they called ghost guns.
It's actually because they.
Don't have serial numbers like all real guns do, and this makes them virtually untraceable. So the first three D printed gun was created in twenty thirteen by a Texas firearms activist named Cody Wilson. Now, it wasn't exactly the same as a real gun. It only fired one bullet at a time, and it was prone to breaking, but Wilson released his design as an open source project that anyone could download or modify, and over the next few years,
he and others kept tinkering. They figured out how to make fully functional guns from three D printed kits and some basic metal parts, and some of these homemade guns were used in actual crimes. So, as you can imagine, this became a concern for law enforcement and for public health and safety groups gun control activists. Now, obviously there are strict rules that govern gun manufacturing in the US,
from licensing to requiring those serial numbers. We also have laws that prohibit people convicted of felonies from owning guns, and three D printing sort of bypasses all of that. So what can governments actually do about this? Well, in the past few years, several states have passed laws regulating three D printed guns, specifically requiring them to have traceable serial numbers, so that's a step and just as pass bringing.
The Supreme Court upheld a twenty twenty two rule that requires serial numbers and background checks for certain three D printed gun kits now, but that decision focused narrowly on some administrative details, so companies that make these kits could potentially get around it, and Cody Wilson has actually asked the Texas Court for an injunction that would prevent enforcement of that twenty twenty two rules. So it's really not clear how all this is going to shake out.
That feels a little depressing.
Actually, all right, well that may be the case, But after the break, I'm going to make it up to you by telling you how three D printing could help solve the housing crisis that I'm intoe.

That's right, and as you mentioned at the top of the show, the idea for today's episode came from one of our listeners who goes by the handle Aurora Borealis, and I love this comment so much I want to read it in its entirety. It says, quote Will and Mango, please do one on three D printing. You can three D print anything from chocolate to houses. It's true, you can use concrete.
Google it.
Yeah.
I like that this had google it because they assume we wouldn't believe them, and then we google it.
So our listeners never lie and we trust you guys completely, but we also fact check. So yes, I did google it, and it turns out that Aurora was absolutely right. There are companies out there that specialize in three D printing full scale houses, and their material of choice is indeed concrete. Now, this begin in Europe in twenty eighteen, and there are now companies in the US and Mexico that are using the process for major development projects.
And to be clear, we're not talking about three D printing cinderblocks and stacking them into a house, right right, Like this is actually printing out all the walls of a house layer by layer.
That is exactly right.
Like you set up an enormous eleven foot tall robotic printer on a build site and you input a three D model of the floor plan, and then the printer's mobile nozzle goes to work squeezing out rounded lines of concrete one on top of the other. And it's kind of like this giant soft served concrete machine. That's fascinating and tasty. So I love that it is fully automated. Do you need humans to work machines? You do need humans, but not as many as you might find on a
normal construction site. You really only need two or three people to oversee the build of this, and the whole system can be controlled by a tablet or a smartphone.
That is so cool.
And since the printer does most of the actual physical labor, the system can operate around the clock.
So to compare, it.
Can take two to six months to build a like a fifteen hundred square foot home the old fashioned way, but you can three D print the same size house in two weeks. Now, if you're willing to go smaller, you can print a five hundred square foot house and less than twenty four hours.
That is bonkers, and they really print every part of the house.
Typically, the only parts of a three D printed house that aren't three D printed are the floor, the roof, and the finishing things like you know, doors and windows. But all of the exterior and interior walls are one hundred percent printed concrete. And it's easy to tell too, because you can see the different layers there. So some people say it makes the walls look like wide whale corduroy or like the bristles on a toothbrush.
I feel like that could take some getting used to, Like I imagine it's a pain to hang things in a house like that, Like you've got to drill through solid concrete just to put up I don't know, paintings or a curtain run. You know.
I thought the same thing, but I actually read an interview with someone who owns a three D printed house and they said that the concrete is actually easier for hanging things because you don't have to worry about running into studs all the time. And another cool thing is that the printer can account for things like electrical and plumbing outlets, so it'll automatically build those gaps into the walls, which means no one has to cut through the concrete
to build them later. Plus, because the concrete is highly energy efficient, three D homeowners tend to have lower utility bills, plus less street noise, and best of all, it is fire, wind and insect resistant. So for someone who lives in an area prone to wildfires or hurricanes or plagues of locusts, like whatever it may be, these three D printed concrete houses could actually be a lifesaver.
That's pretty incredible. And I'm guessing they're a lot cheaper than normal house too, right, Well, you.
Would think so, but no, not really, at least not yet so at the time of the recording. The world's largest three D printed housing development is woolf Ranch in Georgetown, Texas. Now, the homes there come in two and three bedroom models and they started just under four hundred thousand dollars, which is comparable to a similar size regular home in the area. Now that said, the three D printed real estate market
is just emerging. As it scales up and becomes more efficient, those prices could come down, or you'd expect them to come down. And I really hope that's the case, because three D printed homes could go such a long way toward alleviating the worldwide housing short.
You know, this whole time you were talking about three D printed concrete houses, I've been thinking about our old pal, Thomas Edison and how he would build houses by pouring concrete into a giant house sized mole.
And he was just pouring the walls of the house or was it more elaborate than that?
Definitely more elaborate. According to Edison's nineteen seventeen patent, all of the building's parts included the sides, roofs, partitions, bathtubs, floors, et cetera. It would be quote formed of an integral mass of a cement mixture. In theory, the molds could be used over and over again, and Edison hoped the technique would build low income housing in crowded cities. If you look online, you can actually find some of these houses and they're actually beautiful, like the moldings and things
like that. The only problem was that it wasn't exactly practical. His molds were enormous and composed of more than two thousand pieces, which of course made them super expensive to assemble. Now, Edison had a hard time convincing builders to make that initial investment, and even though he offered up the building plans for free, the only concrete houses to ever use his method were part of a small test batch made by his own company.
Yeah, I bet he'd be glad to know that we finally found this work around with three D printing, and that his idea is now reality more than a century later.
You know, it's funny.
Three D printing has been the kind of the wave of the future for the past eighty years, going all the way back to the story I mentioned from the nineteen forties, but now here we are actually catching up to it in the present. It's pretty exciting.
Yeah, definitely. Well, before we sign off, let's do a little fact off. Three D printing has made its mark on restaurants, operating rooms, factories, construction sites, and also on fashion runways. It turns out designers love the tech for its ability to create complex organic structures and intricate patterns with ease, and the result has been this slew of visually striking, wearable art pieces inspired by everything from sacred
geometry to the iridescent feathers of hummingbird. There's even been crossover with the movie industry, where three D printing has been used to create props and costumes, for example, the elaborate headpiece worn by Angela Bassett's Queen in the Black Panther movies with three D printed and if hote couture isn't your thing and you're not a Hollywood star, do not wear you can still wear pree D printed gear. Some designers have started using it to make everyday wearables
like handbags, glasses, frames, and even sneakers. Right, well, here's a fun one I've found. So the Smithsonian website has an online three D digitization portal where you can download free print ready three D models of about one hundred different artifacts that are in their collection. Users can print the models themselves or simply upload the files of their choice to one of the many on demand printing services
out there, such as shape ways or craft Cloud. And that means you can print out things like a t rex skull, a Native American cat sculpture, Amelia Earhart's flight suit and not one, but two life mask of Abraham Link.
That's amazing. You can't have just one.
The artifacts make great decorations, gifts, learning aids, and the program supports the Smithsonian's mission to increase access to their collection for those who can't visit in person.
That is incredible.
Okay, so I brought up Thomas Edison earlier, so it's only fair that I give equal time to Albert Einstein, which is a rule on our show. And thankfully there is a really cool point of overlap between Einstein and three D printing, which is that you can now print free three D replicas of the toy blocks he played with as a child. The printing kit is available on a site called Open Einstein, and it was made through a partnership between the Lego Foundation, Unilever, Ikea, and National Geographic,
which is a wonderful and surprising collective of companies. Anyway, the kit provides models for thirty six building blocks of different sizes and shapes, all of which were scanned directly from the set of wooden blocks that Einstein used when he was a kid. The original blocks were made by this German company, anchor Stein Baluchistan and These must have been popular because they were actually used by a whole
group of budding geniuses. Frank Lloyd Wright had them as a kid, and Buckminster Fuller also had a set of his own. So results may vary with your own kids, but you know, if you're trying to raise a genius, it might be worth a shot, all right.
So we've covered a bunch of things that three D printers can make, but one thing that's still beyond their means, at least for now, is other three D printers. It kind of reminds me of when you were a kid and people are like, if you had one wish and you can't.
Wish for lots more wishes, you know what I mean.
So it would be a neat little trick because even though the cost of three D printers has come down in the last decade, they are still quite pricey. But if new three D printers could be assembled using low cost printed materials, the technology would become accessible to just about everyone. The problem is there are over one hundred different components in each device, and while many of them are simple enough to be reproduced by a single plastic printing unit, other parts.
Aren't printable at all. You think about things.
Like motors bearing circuit boards, but that hasn't stopped makers from trying so. The most famous example is the long running project called rep Rap, and they spent over a decade trying to develop the world's first self replicating three D printer. They went through multiple itterations, made a lot of headway, but the most recent build was still only
able to produce about seventy percent of the parts. Now the project has been installed for a few years now, but with three D printers getting more and more capable by the day, the dream of having one in every home could eventually come true.
I love the idea of a three D printed three D printer in every three D printed home.
Right exactly. That's the dream.
I cannot possibly top that dream. So will you deserve this trophy for this week?
And I'm going to hand it to you.
Look at that, Dylan made a three D printed little trophy here.
You didn't have to do that.
Oh it, dun's the best. It's actually an eyewash coop of us. That is it for today's show, but we will be back next week week with another brand new episode.
