3D Printing and the New Manufacturing Revolution

3D print your own keys for the typewriter

Star Trek has driven my desire for a lot of technological advance. Much of it is already here. For example, Personal Access Display Devices (aka PADD) have come in the form of the many iPads, Surfaces, and other tablets that are ubiquitous today. Some functionality of the tricorder is already available in the pocket sized tablets which (for some reason) we refer to as phones. While I would love to go anywhere on Earth relatively instantly using a matter transporter, what I think we are much closer to today are the replicators that the ships on Star Trek have installed pretty much everywhere.

For the non-trekker, a replicator on the show is a machine capable of creating (and recycling) objects. Replicators were originally seen used to synthesize meals on demand, but in later series they took on many other uses. In the show the replicator works by rearranging subatomic particles to form the object. Here in the 21st century however, we actually have to be able to recreate the object using raw materials. What I am talking about here is 3D printing.

3D printing, also known as additive manufacturing, was developed in the 1980s. But it was not until some patents expired more recently that we started seeing the open-source community develop both commercial and do it yourself printers that brought costs down enough to be accessible to the average joe.

The manufacturing applications of 3D printers are many. Companies can make use of mass customization to allow customers to create a unique version of their product using a simplified interface. Companies looking to prototype their product before having it manufactured in mass can now do that easily. If you as a consumer do not have access to a 3D printer, there are online companies where you can upload your design and have it shipped to you.

In the world of Star Trek we were first introduced to the replicator as a way to be fed. Therefore, I was more interested in 3D printing as a way to indulge my hunger. My interest was peaked when I saw pancakebot, a printer specifically for making pancakes, and a NASA 3D printer making a pizza. Crackers, candy, and pasta are apparently already good candidates for 3D printing as well.

Other applications for 3D printing have so far included a car known as Urbee which has had all of it’s paneling and glass printed using additive manufacturing. Apparel makers and fashion designers of products such as shoes, bikinis, and dresses are using the technology for prototyping. Eyewear frames can be customized for the customer right in the shop. Architects no longer have to create their models by hand. There has even been plans for a 3D printed gun released online leaving many to question the efficacy of gun control in the world of today.

As with all technology it can be used for the betterment of society or its destruction as the firearm example arguably represents. On the other side of the coin medicine has been benefiting from patient specific implants and prosthetics. 3D bio-printing technology has been studied for possible use in tissue engineering applications. Layers of living cells are deposited onto a gel medium or sugar matrix and slowly built up to form three-dimensional structures. 3D printed pills are also on the horizon. Spritam, a drug that treats epilepsy, has already been FDA approved and uses a specialized 3D printing process to enable high doses of the drug in a single pill which quickly dissolves.

The big question is how these printers, once fully accepted and sufficiently advanced will start to affect things like our basic economy. Here again we have technology that replaces labor. How will we adjust as more jobs are taken away by home manufacturing machines? It is certain that we need to readjust our models of employment and distribution. The value of human labor is set to change dramatically. I am anxious to see how that all unfolds.

Drones: The Good, the Bad, and the Unsettling

Your newest delivery man

A few evenings ago, as the library was closing, I was sitting in my car in the parking lot catching up on some things on my phone. Suddenly I heard a tap at the window. There was a woman outside and she was pointing toward the sky. I got out to find out what she was so excited about.

There were some red and green blinky lights hovering in the air above the street a half of a block away from where we were standing. It was too dark to be sure what the lights might have been attached to. “What do you think that is?” she asked. I told her that it seemed like it might be a drone. Once it started moving I was certain it was a drone. I saw a light occasionally come on which I think must have been to facilitate a camera controlled remotely somewhere.

Her theory was that it might be a UFO. I stopped myself from explaining that since UFO stands for “unidentified flying object” and we have not definitively identified the flying object it technically was a UFO. Nonetheless, I could tell that she was very creeped out by what was happening. I reassured her that, since it hovers like a drone and moves like a drone, it was most likely a drone and not a visitor from somewhere else in the universe. We parted ways and I started thinking about the future.

We are not too many years away from wide scale drone delivery. Last year Amazon, the country’s largest online retailer, sent a letter to the FAA regarding the development of their Amazon Prime Air service. When I first heard about this I was pretty excited. Same day delivery via drone sounds pretty nice. But the applications go far beyond my consumer fancy of same day toilet paper or flying fast food. I started thinking about natural disasters and getting medical supplies out to where they are needed much faster than we can now.

Currently there are not that many drones which have the kind of range required to master drone delivery, but you can be sure that there are many companies working on perfecting it. Of course technology companies like Amazon and Google are working on it. But so are parcel delivery services such as FedEx and UPS. The first FAA approved drone delivery has actually already taken place. Although aided by an airplane modified by NASA to work remotely like a drone, this pioneer delivery dispatched medical supplies. Domino’s and a company called Tacocopter are already delivering food now as well.

These delivery applications are all very provocative, but what about those creeper drones that I started with? Even more scary, to me, are the drones being used by our military to attack unsuspecting weddings. Well, those things are already here. It is true that a peeping tom could use a drone to look into your window and there is nothing that you can do about it. In fact, because that it is considered an aircraft, it is a felony to shoot it down. As far as this scenario goes though, I think that the legal situation will change and that drones that are hovering within a certain height on private property will start to face some sort of legal consequence if it has not been invited.

As far as military use of drones goes, I guess the question to ask is whether our technology has outpaced our sense of compassion for humanity. I would argue that perhaps it has, but it certainly is not just because we use drones. For that matter it is not even remotely recent. Ever since humans have been making tools, there were always some made or used as weapons. This is just a modern version of that human foible.

What do you think? Are drones appealing or chilling? Let me know your views in the comments.
