3D maps show brain gene activity

June 25, 2002

A 3D map of the brain’s genetic activity should help researchers pinpoint the neurological underpinnings of autism, schizophrenia and other brain disorders.

3D mash-up maps let you ‘edit’ the world

December 1, 2009

(Ordnance Survey)

As part of a project to demonstrate the potential of 3D mapping, lasers were fired at the coastal resort of Bournemouth in southern England from the ground and from the air to capture the height of buildings, trees and other features, using a technique called Lidar.

Adding information from aerial photos and traditional surveys produced a full-color 3D map, built up from more than 700 million points. The map… read more

3D material that behaves like graphene discovered

June 5, 2014

Scientists at Oxford, SLAC, Stanford and Berkeley Lab have discovered that a sturdy 3-D material, cadmium arsenide, mimics the electronic behavior of 2-D graphene. This illustration depicts fast-moving, massless electrons inside the material. The discovery could lead to new and faster types of electronic devices. (Credit: Greg Stewart/SLAC)

Cadmium arsenide could yield practical devices with the same extraordinary electronic properties as 2D graphene, researchers from Oxford, SLAC, and Berkeley Lab have found.

In addition, the new “semimetal” material exists in a sturdy 3D form that should be much easier to shape into electronic devices such as very fast transistors, sensors and transparent electrodes, the researchers say.

The results are described… read more

3D microvascular network allows for repeated self-healing in composite materials

April 18, 2014

microvascular networks

Researchers at the Beckman Institute for Advanced Science and Technology at the University of Illinois at Urbana-Champaign have created a 3D vascular system that allows high-performance composite materials such as fiberglass to heal autonomously and repeatedly.

Internal damage in fiber-reinforced composites, which are used in structures of modern airplanes and automobiles, is difficult to detect and nearly impossible to repair by conventional methods. A small, internal crack… read more

3D model for lung cancer mimics the real thing

October 12, 2012

lung_cancer_methodist_hospital

Using a new technique that allows scientists to grow lung cancer cells in three dimensions, researchers at The Methodist Hospital and the University of Texas MD Anderson Cancer Center have created a model that uses biological matter to form miniature lungs that mimic the structure and function of real lung cancer, after which human lung cancer cells are added.

The model could accelerate discoveries for a type of cancer that has benefited… read more

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.

3D printed car is as strong as steel, half the weight, and nearing production

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

3D printed meat development funded

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

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 creates hi-res implantable device for customized heart treatment

Could radically transform measurement, treatment, and prediction of cardiac disorders
February 27, 2014

Using an inexpensive 3-D printer, Washington University biomedical engineers have developed a custom-fitted, implantable device with embedded sensors that could transform treatment and prediction of cardiac disorders.

Igor Efimov, PhD, at the School of Engineering & Applied Science at Washington University in St. Louis and an international team of biomedical engineers and materials scientists have created a 3-D elastic membrane made of a soft, flexible,… 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
