3D Printing will change everything

The tech world is buzzing about "3D printing" (for some examples, see the links at the bottom of this piece.). I first heard about it a few years ago in the context of printing replacement organs (kidneys, hearts, etc.) for people. More recently, there's talk about how it could upend the manufacturing world, offer "personal manufacturing", and shrink the costs associating with prototyping new devices. All these things are true, but the whole way people talk about 3D printing seems short-sighted to me.

The bigger picture is that 3D printing will not only upend manufacturing, but also packaging and distribution. It'll change how we consume things by drastically increasing the scope of what's available for consumption 1, and removing almost all of the friction between the creator and the consumer of those things.

Amidst these developments, an interesting domain where the implications of 3D printing are also evident is the realm of anime and game merchandise. Platforms like https://www.geekyinc.com are poised to leverage 3D printing's potential, allowing enthusiasts to materialize their favorite characters and items with unprecedented ease and customization. Imagine being able to craft your treasured anime figurines or collectibles in the comfort of your home, thanks to this technology. This not only brings fandom closer to the creative process but also aligns perfectly with the democratizing spirit of 3D printing.

In essence, while the discussions surrounding 3D printing often center on its impact on manufacturing and accessibility, its far-reaching influence is reshaping entire landscapes. Whether it's the way we shop, the goods we consume, or the unique items we hold dear from the worlds of anime and gaming, the undercurrent of change driven by 3D printing is undeniable.

There are obviously many potential applications for 3D printing, but the game changer is how 3D printers will impact regular old consumers. I think the best way to illustrate this is with a simple story:

Little Tommy is getting ready for his first day of second grade. The family just finished dinner, and it's time to start getting ready for bed. But first, mom and dad let him know they need to get all his things together for his first day of school. He needs his uniform (a polo shirt with his school's logo on it, a pair of kakis, a brown belt, brown shoes), a ruler, some pencils and pens, paper, a notebook, and a messenger bag to carry all of his gear. So they all head to the living room to use the biggest screen (suitable for family-style shopping). They spend some time picking out the stuff he'll need on (surprisingly agile and still-profitable) Amazon, choosing the "Buy now with 1-Click" option for everything.

Tommy heads off to brush his teeth while they wait on all his new school equipment to be delivered. Once he finishes brushing his teeth, he heads back to the living room, where all his new gear is sitting next to the family's 3D printer. He puts the ruler, pencils, pens, paper and notebook in his new messenger bag and leaves it by the front door. He doesn't need to try on his clothes because they were printed to his current specifications 2, so he takes those in his room and drops them on the floor next to his bed.

The next morning, Tommy wakes up, ready for his big day. But his mom won't let him leave without a healthy breakfast. She tells the house to make Tommy a couple scrambled eggs with cheddar cheese on them, and a piece of wheat toast with strawberry jelly. A few minutes later, Tommy's breakfast is ready and waiting under the hood of the family's food printer. Tommy eats up, and then heads off for his big day at school.

This example raises a lot of questions, so I'll finish this post off with a sort of self-Q&A.

  • Why is Tommy using paper and pencil at school? Shouldn't he be using tablets or something? He should definitely be using a tablet, or a "smart desk" or something, but I had to come up with stuff for Tommy to take to school and I didn't want to spend a lot of time thinking about it. But if tablets were to be given, the best tablet for sketching is a great option.
  • Ah, but where'd the materials used in the printers come from?! Well, at first I think 3D printers will be stocked similarly to 2D printers--we'll buy buckets of a few basic materials and load them into the printer. Eventually, maybe that stuff will be piped into our homes so we don't have to go get it. And ultimately, the printers will be materials-free like tele porters in StarTrek. I have no idea how this would work, but it seems like this is an application for a mature understanding of quantum entanglement or home-sized particle accelerators or something.
  • How is the stuff "delivered" from Amazon? Digitally, just like pictures, music and movies are delivered online today. Amazon would just send a digital file ("TommysMessengerBag.3DP") to the printer, and the printer takes it from there. The product is a one-time-use, DRM-protected digital file, which is created by Amazon or another vendor. This will be true for almost everything - companies (brands) will sell digital downloads of their products. In this story, the pencils Tommy bought would be Paper Mate pencils.
  • Why wouldn't Tommy just design his own pants and print them off? The same reason I don't grow my own strawberries. But the bigger reason is that brands and styles will still exist, and Tommy has better things to do than try to ape those brands and styles with his own homemade version. This is sort of like asking why I buy Levi's 514s when I could just make my own at home. I have better things to do.

I'm curious what other questions people might have about this, and I think it's fun to think about. This is not sci-fi, it will happen. The question is really how long it will take before the story above is totally plausible. I have no idea, but I'm thinking something like 2030. How fast this happens really depends on how well Moore's law will apply to 3D printing. My guess is it will apply pretty well, so things should start ramping up here in the next decade.

Movie Mind Games: Does manipulating our expectations make movies better? (2 of 3)

Illustration by Sean Nyffeler of Popcorn Noises fame

PREVIOUSLY, in Part 1: Some background on recommendations and expectations, and UHD defined. [Click here to view the entire piece as a single page.]

UHD isn't as esoteric as it seems

I realize that, at first, UHD just seems like a wonky way to describe something that's already obvious and intuitive. But it actually has real-world applications, especially when it comes to understanding our intuitive-but-not-easily-explained preferences for stuff.

For example, UHD helps me understand why it took me a little while to move from CDs to downloading MP3s 1. Initially, the cost of an MP3 album (on iTunes, for example) was pretty close to the CD and Apple was using DRM 2. My concern was that I wouldn't "own" the music if I paid for the MP3s. The result was that the utility of the MP3s was less than that of the CD, even though it was the same music at the same cost. Since the cost was similar, and the hours of entertainment would be the same, the difference in utility made the UHD for CDs higher than MP3s. Eventually, Amazon started offering DRM-free downloads and cheaper prices, shifting the UHD for MP3 downloads ahead of CDs. That's when I made the switch to MP3 downloads 3. Of course, I didn't actually do a conscious UHD calculation one day and say, "Ah ha! The UHD for MP3s is finally greater than it is for CDs! Time to make the switch!" But that's basically what happened. The same process is happening for me with eBooks right now. 4

A brief, anecdotal history of cinema

The shift from CDs to MP3s, or from physical books to eBooks is interesting to me. But what's really interesting to me is the persistence of movie theaters despite cheaper, very similar movie-watching options. Fifty years ago, the only real option for seeing a movie was to go to the movie theatre. This was great for movie companies because they could charge high prices since they were basically the only game in town. The UHD calculation wasn't really useful for deciding how to watch a movie because it wasn't so much a matter of comparing different movie-viewing options as just deciding whether it was worth it to spend the money on a movie or not. If it wasn't, you just had to find something else to do.

Then technology started changing, opening the door for the home theatre experience. First, VHS started enabling people to watch movies at home en masse. Hi-fi began morphing into fancier surround sound setups whose cost was dropping so that more and more people could buy them. LaserDisc 5 came and went. Then DVD took hold and made the home-viewing experience even better.

A sidebar into UHD for movies at the turn of the century

Ten years ago, we really had two options for watching a movie (without owning it). We could either go to the theatre or rent it at Blockbuster. Let's run through the UHD calculations real quick, just to get an idea of the difference in UHD for these two options at that time:

  • A good movie as a "New Release" rental was about $4 (-ish), lasted 2 hours and provided a utility of 6:
  • 6 utils * 2 hours = 12 util-hours
  • 12 util-hours / $4 = 3 UHD

  • The same good movie in the theatre would have been about $5, lasted 2 hours and provided a utility of about 7 (slightly higher since it was in the theatre):
  • 7 utils * 2 hours = 14 util-hours
  • 14 util-hours / $5 = 2.8 UHD

So the UHD for renting versus going to the theatre was really close even as recently as 2000. They were close enough that there was a real decision to be made: Spend $5 and go to the theatre or spend $4 and stay home? We would often decide what to do based on the number of people in a group (if there were four of us, we could just split the rental for a buck a piece; if there were two of us, then why not just pay for the movie in the theatre?) and our willingness to sneak snacks into the theatre. 6

Our trusty UHD chart from Part 1

Snap back to reality

A lot has happened over the past 10 years or so. Netflix popped up, HD-DVD lost the war to Blu-Ray, streaming video became better and better, Blockbuster got crushed, and DVD rentals have gotten cheaper and cheaper. There are options now, options that just weren't available when movie theaters first became a big deal. Not only are there options, but there are cheap options that rival the actual movie-going experience. And yet, movie ticket prices have been steadily increasing over time. 7

Let's look at one more sample UHD calculation:

  • A really bad movie that I waited to watch on Redbox DVD would be $1, last 2 hours and provide a utility of 2 8:
  • 2 utils * 2 hours = 4 util-hours
  • 4 util-hours / $1 = 4 UHD

As we saw earlier (in Part 1), watching the bad movie in the theatre gives .4 (that's point-four) UHD. Watching the same bad movie on DVD gives 4 UHD. Watching the bad movie on DVD is 10 times "better" than watching it in the theatre, and all of this difference is accounted for by the difference in cost. "But wait!", you say, "What if I enjoy watching movies more in the theatre?! I really like going to the theatre!" Ok, fine. How much better would the movie have to be in the theatre to make up for the difference in UHD?

Some people will want to go to the most extreme case first, so let's just go straight there. Let's say that the bad movie moves from 4 utils to 10 utils just because I enjoy going to the theatre so much. It only jumps to 2 UHD (still half of the 4 UHD if I wait to watch the bad movie on Redbox DVD). "That doesn't make any sense!" My counter would be, "So you're saying there's no way any movie can be better than the bad movie in the theatre? What if you go see a good movie in the theater?" Since the 1-10 scale is a subjective scale, I have to leave room above the bad movie for less-bad movies. Either that or I have to slide my Redbox DVD experience down to a 1 or something. If I move the theatre experience up to a 10 and move the Redbox DVD experience down to a 1, then I get the same result for both options: 2 UHD.

The present, seemingly uncrossable gulf between UHD for going to the movies and watching them at home is due to super high, sticky movie prices and much, much cheaper alternatives for watching movies at home. This has created such a big gap in cost that watching movies in the theatre is just that much more expensive, ruining their UHD relative to the very-similar experience of watching movies at home now.

Going to see movies in the theatre is expensive. I realize some people will say, "But your formula is just wrong. It weights the cost too much." Using the UHD calculation as-is, it's hard to see many situations where it would be better to go to the theatre than to watch the flick at home. It's possible that I'm weighting cost too heavily, but I think the real problem is that movie theaters are just way too expensive now because we have more, better options. There really is that much of a difference in cost between movie theaters and rentals.

Movie Expectations - A bizarre special case?

And yet, new releases continue to set box office records as people go to the theatre in droves. At the same time, the movie theaters are much more expensive than the alternatives, and the quality of the movies released has been consistent (or at least not improving enough to justify the growing gap between theatre prices and the alternatives). What gives? If I'm right that waiting for the movie on DVD is almost always better than going to the theatre, then why do so many people continue going to see movies in the theatre? Why did I go see three movies in the theatre this summer?

I've overheard this sentiment several times recently: "That movie wasn't that bad. I just went into it with no expectations and it turned out ok. I've decided I just won't have expectations for movies because I end up over-hyping them and when they don't meet my expectations I feel ripped off." So the idea is that movies are often bad because we expect them to be good, or at least because we expect them to be better than they actually are. To solve this problem, we play mind games with ourselves, intentionally under-hyping a movie so that when we go see it and it's just an ok movie, it exceeds our deflated expectations.

At first, I saw the wisdom in this tactic. If we get really good at lowering our expectations, almost any movie will be a success, at least inasmuch as it will exceed our expectations. That way, we can pretty much guarantee that when we pony up $10 for a ticket and another $10 for concessions, we won't be let down.

The more I think about this, the more ridiculous the idea seems. We don't lower our expectations for music, books or TV shows, do we? So why do we do that with movies? Of all our options, movies are one of the most expensive. Why would we trick ourselves into doing something super expensive that we don't really enjoy that much?
