Damage to neural tissue is typically permanent and causes lasting disability in patients. But a method for reconstructing neural tissue using patterned nanofibers in 3D hydrogel structures promises to one day help in the restoration of functional neuroanatomical pathways and structures at sites of spinal cord injury, traumatic brain injury, tumor resection, stroke, and neurodegenerative diseases.

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.
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

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,

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

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

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

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

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
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

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.

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