MIT engineers have developed a new desktop 3D printer that performs up to 10 times faster than existing commercial counterparts. Whereas the most common printers may fabricate a few Lego-sized bricks in one hour, the new design can print similarly sized objects in just a few minutes.

The key to the team’s nimble design lies in the printer’s compact printhead, which incorporates two new, speed-enhancing components: a screw mechanism that feeds polymer material through a nozzle at high force; and a laser, built into the printhead, that rapidly heats and melts the material, enabling it to flow faster through the nozzle.

The team demonstrated its new design by printing various detailed, handheld 3D objects, including small eyeglasses frames, a bevel gear, and a miniature replica of the MIT dome—each, from start to finish, within several minutes.

Researchers at the Samsung Advanced Institute of Technology (SAIT) have managed to develop a “graphene ball” which could transform the way we think about batteries.

In a statement on Tuesday, South Korean tech giant Samsung described the graphene ball as a “unique battery material” which allows a 45 percent increase in capacity, as well as charging speeds that are five times faster than standard lithium-ion batteries.

In 2004 researchers at the University of Manchester, in England, managed to isolate graphene for the first time. According to the university, graphene is the thinnest material on the planet, is 200 times stronger than steel, transparent, and is also the world’s “most conductive material.”

Revolutionizing technology and spaceflight.

‘It’s the first-ever sample of metallic hydrogen on Earth, so when you’re looking at it, you’re looking at something that’s never existed before’

For nearly 100 years, scientists have dreamed of turning the lightest of all the elements, hydrogen, into a metal.

Workers took the Keystone oil pipeline offline on Thursday after it spilled 5,000 barrels of oil in rural South Dakota, officials said.

A TransCanada crew shut down the pipeline at 6 a.m. Thursday morning after detecting an oil leak along the line, the company said. The leak was detected along a stretch of the pipeline about 35 miles south of a pumping station in Marshall County, South Dakota.

A new drug being trialled for treating breast cancer and diabetes has been shown to ‘melt away’ the fat inside arteries that can cause heart attacks and strokes.

Researchers from the University of Aberdeen, using pre-clinical mouse models, showed that just a single dose of the drug (Trodusquemine) completely reversed the effects of a disease that causes a host of heart problems.

Atherosclerosis is the build-up of fatty material inside the arteries.
