The end of the builder?

  The giant 3D printer than could create a HOUSE in 24 hours

• Printer can create all fixtures and fittings as it creates house layer by layer 
• Could be used to build a 2500 square foot house in a day

  Scaled up 3D printing technology could be used to build a house in under 24 hours, according to an engineer from the University of Southern California.

Contour Crafting is a layered fabrication technology that uses a huge moveable gantry to build a house in the same way that a 3D printer deposits layers of plastic.

Professor Behrokh Khoshnevis claims that his Contour Crafting construction method can build entire houses with all the fixtures and fittings.

Those behind Contour Crafting believe it could be used to develop entire neighbourhoods

Strong walls are built up layer by layer using concrete with automatic reinforcement, while plumbing and electrics are also added by the system during the building process. 

The nature of the technology means it will also be possible to create curved walls and architecture that is both 'exotic' and 'beautiful', according to Khoshnevis.

Khoshnevis says current construction methods are slow, labour intensive and costly. 

He believes that Contour Crafting could build houses for a fraction of the cost and in significantly less time. 

Khoshnevis says that a 2500-square-foot house can be built in approximately 20 hours with Contour Crafting.

Contour Crafting is a scaled up version of 3D printing. MakerBot (above) is a 3D printer that costs around £600 and uses reels of plastic to print objects

Printed 3D sculptures such as this are becoming increasingly popular as the technology is commercialised

As a result, it could be ideal for emergency housing, commercial or low-income structures.

However, it could also be used to print out customised luxury homes, according to Khoshnevis. 

Furthermore, he believes that the technology could be applied beyond our planet.

'Contour Crafting technology has the potential to build safe, reliable, and affordable lunar and Martian structures, habitats, laboratories, and other facilities before the arrival of human beings,' his website reads. 

The technology has been developed over several years and was presented at the TEDx conference in February.

3D printer creates physical model of fetus for expecting parents

 By Eric Pfeiffer, 

A Japanese clinic is offering parents-to-be the chance to hold their baby months before the child leaves the womb. Using a "Bio-Texture" process and MRI scans, the technology offered by Fasotec and Hiroo Ladies Clinic in Tokyo, Japan, creates a 3D model of the mother's fetus and womb.

The "Shape of an Angel" service costs 100,000 (about $1,276), not including the cost of the MRI.

"We actually got three expectant mothers to try this out. They said it felt great to see how their babies looked before birth, and to be able to actually hold the inside of their own body," Fasotec representative Tomohiro Kinoshita told DigInfo. "They also enjoyed looking at the model after giving birth, thinking, 'This is how my baby looked inside me' and recalling how it felt to be pregnant."

3D printing is an exciting, emerging technology that uses digital models to create real-life objects. Last week, we told you about University of Southern California engineer Behrokh Khoshnevis, who said it would be theoretically possible to build a home in 20 hours using 3D printing technology. There are plenty of critics of the new technology as well. After all, in June a U.S. gunsmith showedused 3D printing to help create a working firearm.

Highest-Resolution Photo Printer Makes Microscopic Color Prints

By Kevin Lee, PCWorld

[Credit: A*STAR]You might have thought that the highest-resolution image would have come in the form of the world’s most massive print. But it is actually printed on the world’s tiniest canvas, measuring just 50 micrometers squared.

Researchers from the Agency for Science, Technology and Research’s (A*STAR) Institute of Materials Research and Engineering (IMRE) in Singapore have created the world’s highest-resolution printer that's capable of producing full-color images at 100,000 dots per inch (dpi). The printer far outpaces current industrial-grade inkjet and laser printers, which can only achieve up to 10,000 dpi.

This printer is nothing like the one in your office, since it doesn't even use ink or dyes to make its images. Instead, the printer actually treats the nano-surface as a lithographic material, manipulating its light-reflecting properties to achieve a full-color image.

The researchers’ inspiration came from stained-glass windows, which have embedded metal particles that scatter the light as it passes though the glass to achieve a certain hue. The printer creates a similar effect by printing the surface with a metal film coated with precisely patterned tiny metal discs. Each of these discs are sized and spaced specifically to reflect light into the individual nano-dots of color that make up the 100,000-dpi image.

Besides making really cool images that can only be viewed under a microscope, the technology could revolutionize the way images are printed, as well as allow for new types of high-density optical data storage.

A*STAR's technology transfer arm, Exploit Technologies Pte Ltd, is already talking with potential collaborators to explore the licensing opportunities of its technology.

Highest-Res Color Printer Ever Fits Images on a Human Hair

IMAGE CACHE

 Jamie Condliffe

This image might look a little grainy to you, but you really should give it a chance. What you're looking at is the output from theworld's highest resolution color printer, and it's actually an extreme close-up of an image that measures just 50 micrometers across—the same width as a human hair.

The printer, developed by researchers at the Agency for Science, Technology and Research (A*STAR) in Singapore, prints images at a staggering 100,000 dots per inch, in full color. To do that, each pixel in the ultra-resolution image is printed by depositing four nanoscale pillars just tens of nanometers tall, which are then capped with silver and gold nanodisks.

By varying the diameter and spacing of these microscopic structures, it's possible to control what color of light they reflect—a concept known as structural color—to develop a palette that can be used for full-color printing. The technique is described in Nature Nanotechnology.

The new method boasts resolution ten times higher than the highest-res laser and inkjet printers. In fact, this image is at the limit of optical resolution: if the researchers put the pixels any closer together, light reflecting off them will diffract, and the two objects blur together. In other words, scientists currently believe that printing can never get higher-res than this.

For a more detailed dive into the science behind the new technique, take a read of Nature's long article on the subject. Or, in the meantime, continue looking at the image in bewildered amazement a little longer. [Nature Nanotechnology via Nature]

Printing technology comes to supercapacitors

Wound (rolled) rechargeable batteries and supercapacitors (Electrochemical Double Layer Capacitors) are similar in construction, with two foil electrodes, the electrodes being kept apart by a porous membrane called a separator soaked in an electrolyte. There are even hybrids of the two. Like batteries, the active electrode material on those current collector foils is usually crudely applied with a scraper using a chemical mud.

 

However, Cellergy is an example of a supercapacitor manufacturer that is now using "an advanced form of screen printing" for its active electrodes and we can expect this level of sophistication to reach the favourite rechargeable batteries - Lithium Ion - in due course.

 

Supercapacitors are starting to appear in energy harvesting, mobile phones, trucks, buses, trams, trains, cars, bikes, wind turbines and much more besides. Their charge-discharge rate, life and "fit and forget" is something battery manufacturers can only dream about. While expensive per Wh, they are improving faster than batteries and there are already five manufacturers offering versions with the energy density of lead-acid batteries. They start a truck when the battery is too cold: they let you take a flash photo with your phone at ten times the distance and they improve the sound of professional audio systems. Indeed, several professors calculate that they could eventually have higher energy density than the best rechargeable batteries of tomorrow - maybe even 1000 Wh plus if using grapheme and more modern deposition technology.

 

The most conservative market forecasts come in at a blistering 30% compound value growth for supercapacitors over the coming decade. In the last three years, the number of supercapacitor manufacturers has doubled to around seventy. In short, supercapacitors, otherwise known as ultracapacitors or Electrochemical Double Layer Capacitors EDLS are one of the top drivers of the new electronics and electrics.

 

This is a game of improving electrode area so graphene and, to a lesser extent, carbon nanotubes come centre stage. Improvement to manufacture includes progressing from scraping of active electrode pastes based on coconut shells to advanced screen printing and carbide-derived-carbon, carbon aerogel and nanocarbon being used with improved electrolytes, both aqueous and organic. The half-way-house of supercabatteries (Asymmetric Electrochemical Double Layer Capacitors AEDLC) has properties between batteries and supercapacitors and is mainly aimed at replacing batteries where price is less important than performance. The lead UltraBattery^TM and the lithium-ion "lithium capacitor" versions clearly have huge potential.

 

Come to this conference to understand the latest position and the future a device that is now of vital interest to all in electronics, electrical engineering, fine chemicals, printed electronics, materials science and vehicles.

There are office files, letter pads, envelops, paper bags and writing boards, all of them made by the students of the Printing Technology section at their Production cum Training centre.

At the Government Vocational Higher Secondary School for the Deaf in Jagathy, the students do not go in search of stationery shops to purchase new notebooks.

They just walk down to their printing lab and at Rs.10, and proudly take back a notebook made by their fellow students.

At their school’s printing lab, its not just stacks of notebooks that one would find. There are office files, letter pads, envelops, paper bags and writing boards, all of them made by the students of the Printing Technology section at their Production cum Training centre.

Arathy Unni, a second year student of Printing Technology, was quick with the cutting machine and as she measured the book on the cutting plate, one could see that she was very precise in her calculations.

“Many of these children are highly skilled. They can rarely concentrate in the theory classes but are quick to learn the practical works. The products made by them are of good standard and they can easily grasp the working of these machines”, said Manju Annie Mathew, vocational teacher of the Printing Technology section.

Speak of their skills, one would have never guess that the identity card hanging around their neck, neatly laminated with nearly perfect binding, is a product of this lab. Some of these students can also make as many as three note books within two lab sessions.

Many who sought admission at the school were interested in joining the course after seeing how their seniors had handled the machines like experts. As soon as their teacher mentioned the name Vishnu, a former student of the school, all nodded with excitement and explained in sign language that he is good.

These students and the staff are looking forward to the full scale implementation of the Vocational Production cum Marketing Co-operative Society at their school. The project, under the Department of Education aims at providing quality training and ensuring permanent jobs for vocationally talented students.

The production is now carried out on a small scale through the society, which is started on an experimental basis at the school. Once developed, we can bring in former students who seek employment and take up mass production orders in binding, lamination and certificate printing works, said J.Baiju, a teacher at the school.
