3D nanotube assembly technique for nanoscale electronics

October 23, 2008
(Evin Gultepe et al.)

Northeastern University researchers have developed a method for high-volume manufactuing of three-dimensional, single-wall carbon nanotube electrical interconnects without the need for high-temperature synthesis.

They assemble the nanotubes into 3D structures by using an applied electric field to coax the nanotubes into deep nanoholes in a porous alumina template.

The method could also integrate well into existing silicon platforms for use in microelectronics, field emission displays, electronic… read more

3D plasma shapes created in thin air

February 28, 2006

The night sky could soon be lit up with gigantic three-dimensional ads, thanks to a Japanese laser display that creates glowing images in thin air.

The display uses an ionization effect which occurs when a beam of laser light is focused to a point in air.

urbee

Picture an assembly line not that isn’t made up of robotic arms spewing sparks to weld heavy steel, but a warehouse of plastic-spraying printers producing light, cheap and highly efficient automobiles.

If Jim Kor’s dream is realized, that’s exactly how the next generation of urban runabouts will be produced, Wired reports. His creation is called the Urbee 2 and it could revolutionize parts manufacturing while creating… read more

August 17, 2012

modern_meadow_meat

Billionaire investor Peter Thiel’s philanthropic foundation has announced a six-figure grant for bioprinted meat, part of an ambitious plan to bring to the world’s dinner tables a set of technologies originally developed for creating medical-grade tissues, CNET reports.

The recipient of the Thiel Foundation’s grant, a Columbia, Mo.-based startup named Modern Meadow, is pitching bioprinted meat as a more environmentally-friendly way to satisfy… read more

3D printer brings animated movie stars to life

March 5, 2009

A 3D printer (“prints” small objects) has been used for the first time, in the new animated movie Coraline, to give characters in an animated movie a far greater range of facial expressions than has been possible before, replacing painstaking hand-sculpting of every facial expression,

3D printer could build moon bases

April 20, 2010

3D Printer

An Italian inventor, Enrico Dini, chairman of the company Monolite UK Ltd, has developed a huge three-dimensional printer called D-Shape that can print entire buildings out of sand and an inorganic binder.

The printer works by spraying a thin layer of sand followed by a layer of magnesium-based binder from hundreds of nozzles on its underside. The glue turns the sand to solid stone,… read more

3D printer makes tiniest human liver ever

April 25, 2013

organovo_liver_tissue_model

Lab-grown livers have come a step closer to reality thanks to a 3D printer loaded with cells, New Scientist reports.

Created by Organovo in San Diego, California, future versions of the system could produce chunks of liver for transplant.

The mini-livers that Organovo made are just half a millimeter deep and 4 millimeters across but can perform most functions of the real thing.… read more

3D printer used to make bone-like material

November 30, 2011

printed bones

Washington State University researchers have used a 3D printer to create a bone-like material and structure for orthopedic procedures, dental work and to deliver medicine for treating osteoporosis. Paired with actual bone, it acts as a scaffold for new bone to grow on and ultimately dissolves with no apparent ill effects.

After just a week in a medium with immature human bone cells, the scaffold was supporting… read more

3D printers: Almost mainstream

December 23, 2011

Robotic-Wallrover

Professional solid modeling tools such as AutoCAD and SolidWorks and 3D printer kits costing less than $1,500 are making 3D printing cost-effective and time-saving, says Computerworld in a comprehensive overview.

Richard Smith used a consumer-grade 3D “plastic jet printer” (The RapMan) and a computer-aided design (CAD) program to design a 3D model of the WallRover, cutting product delivery time from six months to two weeks.

Commercial models… read more

3D Printing and Self Replicating Machines In Your Living Room — Seriously!

April 10, 2009

Its like having a mini factory in your own home: the Reprap machine consists of a half-meter frame enclosing its fabrication workspace, motors, electronic circuitry and an extruder — a device that can squirt out complex three-dimensional patterns of molten plastic filaments that will ultimately solidify into the shape of your 3D object.

How it works: software on a PC takes design files produced by 3-D drawing programs and… read more

Shapeways, a Netherlands-based online 3D printing company, has opened a “factory of the future” in Queens, New York that plans to house 50 high-resolution industrial 3D printers and print custom-designed products a year, Popular Science reports.

The company will allow customers to upload custom 3D designs, and then prints them using materials including acrylic, nylon, glass, gypsum, ceramic, and sandstone, and precious metals such as silver, and ships the… read more

3D printing may put global supply chains out of business: report

October 11, 2012

make_replicator_2

Will 3D printing make global supply chains unnecessary? That’s a real possibility, according to a recent report from Transport Intelligence, Smart Planet reports.

3D printing (or “additive manufacturing,” as it’s called in industrial circles) takes offshore manufacturing and brings it back close to the consumer. It has enormous potential to shift the trade balance. Goods will be cheaper to reproduce within the domestic market, versus manufacturing and then shipping them… read more

3D printing: ‘potential to revolutionize the way we make almost everything’ — President Obama

February 13, 2013

(Credit: White House)

In his State of the Union address Tuesday night, U.S. President Barack Obama noted that “Our first priority is making America a magnet for new jobs and manufacturing. After shedding jobs for more than 10 years, our manufacturers have added about 500,000 jobs over the past three.

“Caterpillar is bringing jobs back from Japan. Ford is bringing jobs back from Mexico. After locating plants in other countries… read more
