The US military wants super-soldiers to control drones with their minds

Posted by in categories: 3D printing, drones, military, neuroscience

I n August, three graduate students at Carnegie Mellon University were crammed together in a small, windowless basement lab, using a jury-rigged 3D printer frame to zap a slice of mouse brain with electricity.

The brain fragment, cut from the hippocampus, looked like a piece of thinly sliced garlic. It rested on a platform near the center of the contraption. A narrow tube bathed the slice in a solution of salt, glucose, and amino acids. This kept it alive, after a fashion: neurons in the slice continued to fire, allowing the experimenters to gather data. An array of electrodes beneath the slice delivered the electric zaps, while a syringe-like metal probe measured how the neurons reacted. Bright LED lamps illuminated the dish. The setup, to use the lab members’ lingo, was kind of hacky.

World’s Biggest 3D-Printer Makes World’s Biggest 3D-Printed Boat

Posted by in categories: 3D printing, employment

University of Maine’s Advanced Structures and Composites Center just printed a 25-foot, 5,000-pound boat, the largest object that has ever been printed. The exorbitant act earned the college no less than three Guinness World Records.

The awards are as follows: one for the world’s largest prototype polymer 3D printer, one for the largest solid 3D-printed object, and one for the largest boat which has ever been produced by a 3D printer. The 3D printer is designed to print objects as long as 100 feet by 22 feet wide by 10 feet high, and can print at 500 pounds per hour.

Cut Your Own Vinyl Records With This $1,100 Machine

Posted by in categories: 3D printing, employment, robotics/AI

3D Printing was one example of how technological advancement made manufacturing accessible to all. Will robots take all the jobs? I doubt it, but technological advancement will make many things inaccessible, accessible to many more than before, by lowering the cost of production. This is but one example.

Better clear out several shelves of storage space, vinylheads, because your record collection is about to expand into infinity. Soon, you’ll be able to get absolutely anything on vinyl. Even better—you’ll be able to make it.

The Phonocut is an at-home vinyl lathe, allowing anyone with a digital audio file and a dream to make a 10-inch record.

Shape-shifting robot built from ‘smarticles’ shows new locomotion strategy

Posted by in categories: 3D printing, robotics/AI

Check out the new shape-shifting robot made out of “smarticiles” that show a new locomotive strategies!! ~via ScienceDaily… #churchofperpetuallife #perpetuallife #sciencedaily

Building conventional robots typically requires carefully combining components like motors, batteries, actuators, body segments, legs and wheels. Now, researchers have taken a new approach, building a robot entirely from smaller robots known as “smarticles” to unlock the principles of a potentially new locomotion technique.

The 3D-printed smarticles — short for smart active particles — can do just one thing: flap their two arms. But when five of these smarticles are confined in a circle, they begin to nudge one another, forming a robophysical system known as a “supersmarticle” that can move by itself. Adding a light or sound sensor allows the supersmarticle to move in response to the stimulus — and even be controlled well enough to navigate a maze.

Though rudimentary now, the notion of making robots from smaller robots — and taking advantage of the group capabilities that arise by combining individuals — could provide mechanically based control over very small robots. Ultimately, the emergent behavior of the group could provide a new locomotion and control approach for small robots that could potentially change shapes.

3D printing technique accelerates nanoscale fabrication 1000-fold

Posted by in categories: 3D printing, engineering, nanotechnology

Using a new time-based method to control light from an ultrafast laser, researchers have developed a nanoscale 3D printing technique that can fabricate tiny structures 1000 times faster than conventional two-photon lithography (TPL) techniques, without sacrificing resolution.

Despite the high throughput, the new parallelized technique—known as femtosecond projection TPL (FP-TPL)—produces depth resolution of 175 nanometers, which is better than established methods and can fabricate structures with 90-degree overhangs that can’t currently be made. The technique could lead to manufacturing-scale production of bioscaffolds, flexible electronics, electrochemical interfaces, micro-optics, mechanical and optical metamaterials, and other functional micro- and nanostructures.

The work, reported Oct. 3 in the journal Science, was done by researchers from Lawrence Livermore National Laboratory (LLNL) and The Chinese University of Hong Kong. Sourabh Saha, the paper’s lead and corresponding author, is now an assistant professor in the George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology.

This flat structure morphs into shape of a human face when temperature changes

Posted by in categories: 3D printing, materials

Researchers at MIT and elsewhere have designed 3D printed mesh-like structures that morph from flat layers into predetermined shapes, in response to changes in ambient temperature. The new structures can transform into configurations that are more complex than what other shape-shifting materials and structures can achieve.

As a demonstration, the researchers printed a flat mesh that, when exposed to a certain temperature difference, deforms into the shape of a . They also designed a mesh embedded with conductive liquid metal, that curves into a dome to form an active antenna, the resonance frequency of which changes as it deforms.

The team’s new design method can be used to determine the specific pattern of flat mesh structures to print, given the material’s properties, in order to make the structure transform into a desired shape.

NASA’s rolling Shapeshifter robot concept splits into two drones

Posted by in categories: 3D printing, alien life, drones, robotics/AI

When NASA’s Cassini performed more than 100 flybys of Saturn’s moon Titan, scientists piecing together the data began forming a picture of a pretty treacherous environment, with liquid methane rain, cold rivers and icy volcanoes all potentially part of the mix. The agency’s scientists are already at work developing vehicles that will one day be used to explore such surrounds, with its newly revealed Shapeshifter robot another interesting example.

The Shapeshifter is a developmental concept at this early stage, and is designed to change its shape depending on the type of alien terrain it encounters. The team at NASA’s Jet Propulsion Laboratory have 3D printed a prototype of the robot that is already capable of some impressive maneuvers.

Future Tech: Spinning a Space Station

Posted by in categories: 3D printing, engineering, robotics/AI, solar power, space, sustainability

The ultimate way of building up space structures would be to use material sourced there, rather than launched from Earth. Once processed into finished composite material, the resin holds the carbon fibres together as a solid rather than a fabric. The beams can be used to construct more complex structures, antennae, or space station trusses. Image credit: All About Space/Adrian Mann.

The International Space Station is the largest structure in space so far. It has been painstakingly assembled from 32 launches over 19 years, and still only supports six crew in a little-under-a-thousand cubic metres of pressurised space. It’s a long way from the giant rotating space stations some expected by 2001. The problem is that the rigid aluminium modules all have to be launched individually, and assembled in space. Bigelow Aerospace will significantly improve on this with their inflatable modules that can be launched as a compressed bundle; but a British company has developed a system that could transform space flight, by building structures directly in space.

Magna Parva from Leicester are a space engineering consultancy, founded in 2005 by Andy Bowyer and Miles Ashcroft. Their team have worked on a range of space hardware, from methods to keep Martian solar panels clear of dust, to ultrasonic propellant sensors, to spacecraft windows. But their latest project is capable of 3D printing complete structures in space, using a process called pultrusion. Raw carbon fibres and epoxy resin are combined in a robotic tool to create carbon composite beams of unlimited length – like a spider creating a web much larger than itself. Building structures in space has a range of compounding virtues, it is more compact than even inflatables, as only bulk fibre and resin need to be launched. Any assembled hardware that has to go through a rocket launch has to be made much stronger than needed in space to survive the launch, printed structures can be designed solely for their in space application, using less material still.
