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.

Welcome to the Future: Wearables Part 2 - Android Wear

Our ability to tell time has come a long way

I too have been using one of these new wearable computers. RD went through his thoughts on the Microsoft Band seeing as he is a Windows Phone user. I, being primarily an Android user, went with a Samsung Gear Live which runs the Android Wear platform. I have been using it since July of 2014. After a little over a year, I can say that I will be sticking with it.

When I first saw Android Wear announced, I was curious. I did not think that I would end up using one of the first generation watches. I did not immediately plan to buy one as soon as one was available. Unlike RD, I was not going to the store hoping they had one in stock. I could have cared less if they were out of stock. How I came to purchase one was that I had traded in my old MacBook Air for some Amazon credit. After adding my Chromebook to the cart, I had about the same amount left over as the cost of the Gear Live. Amazon happened to have it in stock, so I thought I’d give it a try.

Before I go any further, I think that it might be notable to explain that, to this day, I am not convinced of the utility that a smartwatch provides to the average consumer. I once kept my phone in my left pocket. My watch goes on my left hand. It is not effectively more convenient for me to look at my wrist and get vibrations on my wrist as opposed to the same in my pocket. If I still used a pocketable smartphone, I would not have even tried an Android Wear watch.

At the time that I decided that my use case was such that I might benefit from Android Wear, I had a seven inch tablet, the Nexus 7, as my carry around communication device. At one point I had both an iPhone and a full sized iPad and had become frustrated by the complexity and needlessness of two touch screen devices and realized that I could do everything just fine with one smallish Android tablet. The only issue with this was that I often missed notifications. The tablet stayed in my bag or on a table somewhere in the house. I saw this watch as the solution to that issue.

Android Wear works great for getting me the notifications that I had been missing and freeing me from feeling that I need to be close enough to my tablet to hear the audible notifications. But Android Wear has other benefits too. I can read and reply to messages without having the device in my hand. The car connects to my tablet via bluetooth when I start it up and I can play music without digging it out of my bag. I like being able to set timers when I am cooking without touching a screen with my food saturated hands. Having my alarm on my wrist means that it targets no one but me to wake up at the early hours that otherwise bother family members who prefer to keep sleeping. These are all nice extras beyond my original purpose for the device. The fitness tracking features are nice too, but might be better with GPS baked into the watch since I do not want to take my tablet for a run with me.

In summary, Android Wear is a nice accessory for me. I still do not know how useful it is in general and question how far the niche customer base for wearables can drive market demand enough to keep them in production. I think that most people have long since left a watch out of their accessory arsenal and prefer to keep it that way. If wearables are to thrive, I believe a little more creativity and innovation, or at least evolution, will be required. We shall see what the future brings in this space.
