The Future of 3D Printing
“Three-dimensional printing makes it as cheap to create single items as it is to produce thousands and thus undermines economies of scale. It may have as profound an impact on the world as the coming of the factory did....Just as nobody could have predicted the impact of the steam engine in 1750—or the printing press in 1450, or the transistor in 1950—it is impossible to foresee the long-term impact of 3D printing. But the technology is coming, and it is likely to disrupt every field it touches. ”
—The Economist, February 10, 2011

How Do I Get Started?
"In traditional construction you have to make a mould of wood and you fill it with concrete and then you take out the wood - it's a waste of time and energy.
"You can print what you want - it's a more direct way of constructing."
The first "landscape house" should be in position by 2014
"Each room is printed separately on site before being assembled into one house...Each room is different and consists of complex and tailormade architecture and unique design features...Each printed room consists of several parts, which are joined together as large Lego-like blocks."
"Contour Crafting technology has great potential for automating the construction of whole structures as well as sub-components. Using this process, a single house or a colony of houses, each with possibly a different design, may be automatically constructed in a single run, embedded in each house all the conduits for electrical, plumbing and air-conditioning.
The potential applications of this technology are far reaching including but not limited to applications in emergency, low-income, and commercial housing.
Our research also addresses the application of Contour Crafting in building habitats on other planets. Contour Crafting will most probably be one of the very few feasible approaches for building structures on the Moon and Mars, which are being targeted for human colonization before the end of the new century."
Not just for humans...

"The 2D scans were not precise enough...they used a Makerbot Replicator 2X to create a 3D-printed model of Roland's heart, with all of the defects. The 3D-printed heart was printed in three separate pieces so that the surgeons could take it apart and look inside.
[Dr.] Austin spoke with the Courier Journal, where he said: "Once I had a model, I knew exactly what I needed to do and how I could do it". The 3D-printed heart allowed Austin to cut out time that would normally be wasted on exploratory surgeries, as well as shorten the time operating on Roland's heart.
The surgery was successful on February 10."
"Through a collaboration with Medical Modeling Inc. in Golden, Colo., Dr. Michael Egnor and Dr. Elliot Duboys were able to virtually plan the entire surgery beforehand. Additionally, the company created 3D printed before-and-after models of Gabriel’s skull for the surgeons, so they could accurately predict how the operation’s results would look."
Consider, for example, the case of patient Millie, a canine with a skull deformity that was limiting her quality of life.
“It’s difficult to fully understand the malformation until we have it in our hands,” [Dr. Galban] said via a release. “That usually doesn’t happen until we’re in surgery.”
Galban worked with PennDesign’s Stephen Smeltzer and Dennis Pierattini to produce models based on CAT scan files of Millie’s head that lead to a 3-D printed model of the pup’s skull.
Craig Gerrand, consultant orthopaedic surgeon at Newcastle upon Tyne Hospitals NHS Foundation Trust, used 3D printing to create a pelvis – the first of its kind – for a patient who had lost his to cancer.
In a medical first, doctors used plastic particles and a 3-D laser printer to create an airway splint to save the life of a baby boy who used to stop breathing nearly every day.
In a single day, they "printed out" 100 tiny tubes, using computer-guided lasers to stack and fuse thin layers of plastic instead of paper and ink to form various shapes and sizes. The next day, with special permission from the Food and Drug Administration, they implanted one of these tubes in Kaiba, the first time this has been done.
"Researchers at the University of Texas in El Paso are using 3D printers to make tissue, including skin that could one day help treat wounds and other medical problems."
Helping students "see" history.
Study fossils without risk of damage.
“Combined with advanced 3D printing, we can now slice though the ancient fossil skulls and print them in halves showing the full anatomy in clear definition. This will no doubt revitalise palaeontology.”
"When [Dr. Olsen] printed out one protein for a colleague, they found a curvy 'tunnel' of empty space running right through it. The conduit couldn't be seen clearly on the computer screen, but a puff of air blown into one side of the model emerged from the other. Determining the length of such tunnels can help researchers to work out whether, and how, those channels transport molecules. Doing that on the computer would have required some new code; with a model, a bit of string did the trick."
Help scientists visualize molecules.
"Astronomers Carol Christian and Antonella Nota of the Space Telescope Science Institute in Baltimore, Md., are experimenting with the innovative technology to transform astronomy education by turning images from NASA's Hubble Space Telescope into tactile 3-D pictures for people who cannot explore celestial wonders by sight."
