3-D printing on the micrometer scale

Three-dimensional printers are popping up everywhere these days. Some are small enough to fit in a briefcase and others are large enough to build print houses, but scientists at the Vienna University of Technology are going for the microscopic. Earlier this year, the university built a 3D printer that uses lasers to operate on a tiny small scale. Now they're refining the technique to enable precise placement a selected molecule in a three-dimensional material. This process, called “3D-photografting,” can potentially be used to create a “lab on a chip” or artificially grow living tissue. Read More

New technology allows for high-speed 3D printing of tiny objects

Are 3D printers not amazing enough already? Apparently some scientists at the Vienna University of Technology (TU Vienna) didn’t think so, as they have now built one that can create intricate objects as small as a grain of sand. While the ability to 3D-print such tiny items is actually not unique to the TU Vienna device, the speed at which it can do so is. According to the researchers, this makes the commercial production of things such as medical implants much more viable. Read More

Using lasers to look through container walls from a distance and detect explosives

Contrary to what some cartoons might have led you to believe, explosives aren’t always emblazoned with the letters TNT making them easy to identify. Some people will actually go to the trouble of disguising explosives by placing them in nondescript containers. This means that to analyze them, some close quarter examination that puts someone at risk is usually required. Researchers at the Vienna University of Technology (TU Vienna) have developed a detection method using laser light that allows explosives to be detected not only from distances of over 100 meters (328 ft), but works even when the explosives are hidden inside an opaque container.

Crab shells used to produce cheaper pharmaceuticals

Crabs and lobsters ... they're not just for eating, anymore. Chitin, one of the main components of their exoskeletons, has recently found use in things such as self-healing car paint, biologically-compatible transistors, flu virus filters, and a possible replacement for plastic. Now, something else can be added to that list. Researchers from the Vienna University of Technology are developing a technique in which chitin is being used to cheaply produce a currently very-expensive source of antiviral drugs. Read More

Self-powered sensors developed for monitoring aircraft integrity

Because structural integrity is so crucial to the safe operation of aircraft, their bodies are regularly inspected for signs of faults such as stress fractures. Some of these fractures can be virtually invisible to the human eye, so scientists are looking into the use of permanently-installed sensors, that would continuously provide information on the state of various parts of the aircraft. Given that one commercial airliner could potentially utilize hundreds of these sensors, however, running wiring to all of them could get quite complex. Using battery-operated sensors is one option, although ground crews would be constantly checking and changing batteries, plus it would be wasteful. Researchers from EADS Germany and the Vienna Institute of Technology now think they might have a better alternative – self-powered sensors that wirelessly transmit data. Read More

Prototype miniature 3D printer could become an affordable product

With the recent release of the Trimensional app, people can now use their iPhones as inexpensive 3D scanners. Not only can users take three-dimensional images of objects, but they can use those images to create actual physical models ... as long as they have access to a 3D printer. Currently, such printers tend to be large, expensive devices that are usually only found in places like universities or industrial design companies. That could soon change, however, as researchers at the Vienna University of Technology (TU Vienna) have created a prototype compact, affordable 3D printer. Read More
