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

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

3D printing factory opens in New York City

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 for new tissues and organs

June 19, 2009

Rapid prototyping might one day allow kidney, liver and muscle tissues to be constructed in the laboratory from a patient’s own cells with close-to-natural detail ready for transplantation.

3D printing lowers environmental impact, says study

October 5, 2013

3d_printed_blocks_large

Making things at home on a 3D printer uses less energy — and therefore releases less carbon dioxide — than producing it in a factory and shipping it to a warehouse.

That’s according to a study led by Joshua Pearce, an associate professor of materials science and engineering/electrical and computer engineering at Michigan Technological University.

The team conducted life-cycle impact analyses on three products:… 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

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

3D printing: the desktop drugstore

A small Indian village is perhaps the last place you would expect to see the future of manufacturing, but in the Maharashtra region, there are plans to create one of the hottest pieces of technology around, BBC Future reports.

“Learning while doing” is the philosophy behind an educational project in Pabal called the Vigyan Ashram — part of a worldwide project called FabLab, set up… read more

3D Projection Without the Glasses

November 16, 2000

LAS VEGAS — Perhaps the most exciting technology at Comdex this year was a 3D display that projected volumetric images into thin air, prompting show goers to gasp, burst out laughing and run around the booth in excitement.
At the back of one of the exhibit halls, Dimensional Media set up a booth full of 3D displays that projected images — of objects such as cell phones or soda cans… read more

3D reconstruction of neuronal networks uncovers hidden organizational principles of sensory cortex

Most cortical circuitry interconnects neurons across cortical columns, rather than within

An international research team has reconstructed anatomically realistic 3D models of cortical columns of the rat brain, providing unprecedented insight into how neurons in the elementary functional units of the sensory cortex called cortical columns are interconnected.

The models suggest that cortical circuitry interconnects most neurons across cortical columns, rather than within and that these “trans-columnar” networks are not uniformly structured: they are highly specialized and integrate… read more

3D sketching system ‘revolutionizes’ design interaction and collaboration

University of Montreal researchers present their Hyve-3D system at SIGGRAPH 2014 conference

University of Montreal researchers have developed a collaborative 3D sketching system called Hyve-3D (Hybrid Virtual Environment 3D), which they presented at the SIGGRAPH 2014 conference in Vancouver this week.

“Hyve-3D is a new interface for 3D content creation via embodied and collaborative 3D sketching,” said lead researcher Professor Tomás Dorta of the university’s School of Design.

Photovoltaic Array

http://web.mit.edu/newsoffice/2012/three-dimensional-solar-energy-0327.html

MIT researchers are building cubes or towers that extend solar cells upward in three-dimensional configurations and show power output ranging from double to more than 20 times that of fixed flat panels with the same base area.

The biggest boosts in power were seen in the situations where improvements are most needed: in locations far from the equator, in winter months and on cloudier days.… read more
