Nanoengineers can print 3D microstructures in mere seconds [Jacobs School of Engineering: News & Events] San Diego, Calif., September 13, 2012 – Nanoengineers at the University of California, San Diego have developed a novel technology that can fabricate, in mere seconds, microscale three dimensional (3D) structures out of soft, biocompatible hydrogels. Near term, the technology could lead to better systems for growing and studying cells, including stem cells, in the laboratory. Long-term, the goal is to be able to print biological tissues for regenerative medicine. For example, in the future, doctors may repair the damage caused by heart attack by replacing it with tissue that rolled off of a printer. Reported in the journal Advanced Materials, the biofabrication technology, called dynamic optical projection stereolithography (DOPsL), was developed in the laboratory of NanoEngineering Professor Shaochen Chen.
Current fabrication techniques, such as photolithography and micro-contact printing, are limited to generating simple geometries or 2D patterns. Abstract - SpringerLink.

The semiconductor that continues to reinvent display At the heart of every DLP® projection system is an optical semiconductor known as the DLP® chip, which was invented by Dr.
Larry Hornbeck of Texas Instruments in 1987. The DLP chip is perhaps the world's most sophisticated light switch. It contains a rectangular array of up to 8 million hinge-mounted microscopic mirrors; each of these micromirrors measures less than one-fifth the width of a human hair. When a DLP chip is coordinated with a digital video or graphic signal, a light source, and a projection lens, its mirrors can reflect a digital image onto any surface. 2. A DLP chip's micromirrors tilt either toward the light source in a DLP projection system (ON) or away from it (OFF). The bit-streamed image code entering the semiconductor directs each mirror to switch on and off up to ten thousand times per second. 3.
The on and off states of each micromirror are coordinated with these basic building blocks of color. 4. DLPLIGHTCRAFTER - DLP® LIGHTCRAFTER™ DLP® LightCrafter™ is a compact evaluation module for integrating projected light into industrial, medical, and scientific applications. This DLP-based platform enables faster development cycles for end equipments requiring small form factor, lower cost and intelligent, high-speed pattern display. DLP LightCrafter features the 0.3 WVGA chipset, which provides a variety of embedded functionality such as: structured light pattern projection, intelligent lighting, wavelength selection and portable display. Developers can easily create, store, and display high-speed pattern sequences through DLP LightCrafter’s USB-based application programming interface (API) and easy-to-use graphical user interface (GUI). The module also features the powerful TMS320DM365 digital media processor based on DaVinci™ technology from Texas Instruments.
The DLP LightCrafter includes a 20 lumen, RGB LED light engine developed and manufactured by Young Optics International. Cables and power supply sold separately. DLP LightCrafter.

Technische Universität Wien : The World’s Smallest 3D Printer. 3D-printer at TU Vienna Markus Hatzenbichler and Klaus Stadlmann with their micro-printer Printers which can produce three-dimensional objects have been available for years. However, at the Vienna University of Technology, a printing device has now been developed, which is much smaller, lighter and cheaper than ordinary 3D-printers.
With this kind of printer, everyone could produce small, taylor-made 3D-objects at home, using building plans from the internet – and this could save money for expensive custom-built spare parts. Several scientific fields have to come together, to design a 3D-printer. Layer for LayerThe basic principle of the 3D-printer is quite simple: The desired object is printed in a small tub filled with synthetic resin. This method is not designed for large-scale production of bulk articles – for that, there are cheaper alternatives. Picture download.
