A New Spin On 3D Printing Can Produce an Object In Seconds

An anonymous reader quotes a report from Ars Technica: A 3D model is sliced up into hundreds of 2D horizontal layers and slowly built up, one layer at a time. This layer-by-layer process can take hours or even days, but what if we could print the entire model at once? A new technique demonstrated by researchers from Switzerland's Ecole polytechnique federale de Lausanne (EPFL) -- and further detailed in this Nature article -- does just that and can print an entire model in seconds. The new techn...

New Super-Fast 3D Printing Method: Prints in Seconds, High-Res, No Layers, Soft or Hard Materials

Researchers at Switzerland's EPFL (Ecole polytechnique fédérale de Lausanne) have invented a new 3D printing method similar to stereolithography, but with far faster results.The similarity between the two systems is that both use photosensitive resins cured by lasers. Where they differ is that EPFL's system, which is tomography-inspired, doesn't build layer-by-layer on a vertically-moving platform, but instead comprehensively blasts their beams into a spinning container holding the resin. This e...

3D Printers Are Finally Starting to Work More Like Star Trek's Replicators

Transporters? Spaceships that can travel at the speed of light? Star Trek introduced us to many fantastical technologies that have us looking forward to the 23rd century. But we might not have to wait that long for all the tech Captain Kirk had to play with, as 3D printing has taken another big step toward making…Read more...

Researchers find a way to 3D print whole objects in seconds

When you think of 3D printing, you probably imagine a structure being created layer by layer, from the bottom up. Now, researchers from Switzerland's Ecole polytechnique fédérale de Lausanne (EPFL) say they have developed a completely new way of creating 3D objects that offer remarkable resolution "in record time."

Personalized cancer vaccines

The only therapeutic cancer vaccine available on the market has so far showed very limited efficacy in clinical trials. EPFL researchers are currently working on an alternative. They have developed a platform that allows a cancer vaccine to be delivered to a precise location and stimulate the immune system in a safe way -- thereby overcoming one of the two obstacles to creating an effective vaccine.

A novel formulation to explain heat propagation

Researchers at EPFL and MARVEL have developed a novel formulation that describes how heat spreads within crystalline materials. This can explain why and under which conditions heat propagation becomes fluid-like rather than diffusive. Their equations will make it easier to design next-generation electronic devices at the nanoscale, in which these phenomena can become prevalent.

Breathing may change your mind about free will

Is free will just an illusion? For decades, a signal from the brain called the 'readiness potential' has been interpreted to mean that free will may be an illusion. Backed by signals from the brain and lungs, EPFL scientists have discovered that the readiness potential is in fact coupled to breathing and that acts of free will happen as you exhale -- providing an unexpected perspective on free will.

EPFL researchers propose concept to capture trucks’ CO2 and covert it to liquid fuel while driving

In Switzerland, researchers at EPFL have patented a new concept that could cut trucks’ CO2 emissions by almost 90%. It involves capturing CO2 within the exhaust system, converting it into a liquid and storing it on the vehicle. The liquid CO2 would then be delivered to a service station and where it will be turned back into fuel using renewable energy. Scientists propose to combine several technologies developed at EPFL to capture CO2 and convert it from a gas to a liquid in a process that re...

Proposed CO2 Capture System Could Reduce Truck Emissions By 90 Percent

Researchers at the Swiss Federal Institute of Lausanne (EPFL) have come up with a new concept for capturing CO2 from truck exhausts which could reduce emissions by up to 90 percent. Engadget reports: In a paper published in the journal Frontiers in Energy Research, the researchers propose capturing carbon dioxide from a truck's exhaust pipe and turning it liquid, which is stored in a tank on the vehicle's roof. This liquid carbon dioxide can then be delivered to a service station where it can be...

This tiny, soft robo-bug scoots with smarts and survives swats

Nature is a good source of inspiration for roboticists, but it’s rare that nature’s elegance and genius can be replicated in any real way. Still, we’re getting closer. This tiny insect-like robot is made of soft materials and weighs less than a gram, yet can move quickly and with some intelligence — and is robust enough to survive a pounding from a fly swatter. For the most part, tiny robots like this are compromises. For instance, they can move quickly, but only with external power. Or they can...

When grown right, palm oil can be sustainable

Turning an abandoned pasture into a palm tree plantation can be carbon neutral, according to a new study by EPFL and the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL). These findings, based on measurements of 56-year-old palm tree plantations in Colombia, suggest we may be able to find sustainable alternatives to deforestation for the production of palm oil -- a practice currently under fire by environmentalists.

Access to mobile phone location data can help understand spread of vector-borne diseases

Researchers from EPFL and MIT have shown that human mobility is a major factor in the spread of vector-borne diseases such as malaria and dengue even over short intra-city distances. In a paper published in Scientific Reports, the team compares different mobility models and concludes that having access to mobile phone location data can prove crucial in understanding disease transmission dynamics - and, ultimately, in stopping an outbreak from evolving into an epidemic.
