If it's possible to 3D print blood vessels, robots, and guns, then why shouldn't you be able to 3D print your own personal electronics? Well, now you can -- in the lab at least.
University of Warwick researchers have developed a conductive plastic composite material that can be used with unmodified, low-cost, hobbyist 3D printers to make functional electronic devices. The devices can even be custom-designed, such as tailoring a game controller to fit the shape of a particular user's hand.
The team, headed by Simon Leigh of the university's School of Engineering, says the inexpensive material, called "carbomorph," makes it possible to print out electronic tracks and sensors as part of a 3D-printed structure.
To date, the researchers have used the material to print objects with embedded flex sensors, such as a mug that can sense how full it is, or those with touch-sensitive buttons, such as a working computer game controller. The results were published in an article in the open-access journal PLOS One.

The printer can create touch-sensitive areas in the structure that can be connected to a simple, printed circuit board.
The computer game controller was printed using a Bits from Bytes BFB3000, Leigh told Design News in an email. "It's designed to interface with an Arduino board, then it can be plugged into a PC and used to play any game on your PC," he wrote. "The idea behind it is that you could in theory customize the layout of the controller hardware to your own specification."
Leigh and his team envision the technology being used to 3D print functioning electronic devices, making those devices more individualized. This could, he says, reduce electronic waste by customizing products to make them closer to what users want, and fitting their unique needs. Another application could be embedding sensors in products and monitoring how people use them, so designers could better understand how people tactilely interact with products.
The most immediate, short-term use Leigh envisions is giving the next generation of young engineers the hands-on experience of designing and producing electronic products in the classroom with advanced manufacturing technology like 3D printing. According to Leigh, existing open-source electronics and programming libraries can be used for monitoring the printed sensors.
One of the biggest advantages to 3D printing electronics is the fact that sockets for connecting the devices to equipment, such as interface electronics, could be printed out, rather than using conductive glues or paints. That's the research team's next step: to print more complex structures and electronic components, including the wires and cables that connect the 3D printed devices to computers.
I believe that in 20 years, we will be 3D printing organs like the liver, pancreas, etc. I thought robotics would be transformative, and it is in biomechanical medical procedures, but 3D printing is certainly leading the pack.
Good question, Chuck. I, too, had previously heard of conductive plastics used in flex circuits. This is the first time I've seen them combined with 3D printing. 3D printing isn't yet aimed at high volumes, but several efforts are underway to do just that, including this one we wrote about http://www.designnews.com/author.asp?section_id=1392&doc_id=248401
I'll bet we can look forward to all sorts of electronic hacks in the future with this techology. I can imagine future nerd clubs sharing files (and a 3D electronic printer) that you can interlink to build all sorts of stuff.
Wow, Cabe, you weren't kidding! I remember hearing about MBE a while ago, but didn't realize it was a 3D printing method. Must be insanely expensive. I'd bet a lot of technology has been inspired by Star Trek shows.
Cabe, that gave me a good laugh. I don't think 3D printing technology has yet arrived that can print at the molecular level :-). Regarding why do this, the main point is customizing the electronics to fit an individual's needs, such as the customized grip mentioned in the article.
I suspected you were a Kurzweil follower, BrainiacV. For those who want to know more about Kurzweil joining Google, see EE Times' story from yesterday here:
Sounds like you've been reading Raymond Kurzweil's books, BrainiacV. I don't know if any of his predictions involve 3D printing, but the two of you seem to be on the same wavelength. He has written two books on living forever: "Fantastic Voyage: Live Long Enough to Live Forever and "Nine Steps to Living Well Forever." Kurzweil's a prolific inventor (notably, the Kurzweil reader) and, it should be mentioned, former Design News Engineer of the Year.
I'm looking forward to a bioprinted liver to replace my current transplant when it wears out in about 20 years. It would be nice to get off the expensive immunosuppressant drugs I have to take to prevent rejection.
But why stop with existing organs, why not make a few improvements while we are at it?
I find it interesting that they are talking about including 3D printers on space flights so they can make replacement parts. Would have come in handy for Apollo 13.
I thought robotics were going to be the future, right now it looks like 3D printing is going to be the transformative technology.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
