SUNDAY TIMES - South Africa in talks with Airbus, Boeing to print 3D parts. Officially launched in 2011 and backed by government, the Aeroswift research project last year produced its first three demonstrator parts – a pilot’s throttle lever, a condition lever grip which is part of the throttle assembly, and a fuel tank pylon bracket, in a digital process known as 3D printing, or additive layer manufacturing.

Increasingly adopted by the automotive, aerospace and military industries as a cheaper way of making complex parts, the new manufacturing process could save millions of dollars on fuel and production costs as aircraft makers replace alumimum bodies with lighter materials such as titanium alloys. "How best to commercialise the process is a discussion we are currently having with the Aeroswift partners and relevant government agencies," said Simon Ward, Airbus's vice president for international cooperation in Toulouse. South Africa ranks fourth in world titanium reserves, behind leader China, Australia and India, according to the U.S.

Scary new world of 3D printing

But with important patents running out this year, new printers that use metal, wood and fabric will become more widely available - putting the engineering world on the cusp of historical change. The defence industry is at the leading edge of this innovation, and the US military was already investing in efforts to print uniforms, synthetic skin to treat battle wounds, even food, said Alex Chausovsky, an analyst at IHS Technology. Scientists at the Massachusetts Institute of Technology have invented "4D printing" - creating materials that change when they come into contact with elements such as water. One day that could mean things such as printed uniforms that change colour depending on their environment. Late last year, UK defence firm BAE Systems put the first printed metal part in a Tornado jet fighter. Graphene 3D Lab unveils first 3D-printed graphene battery. Oct. 24, 2014 Graphene 3D Lab, based in Calverton, New York, announced in September that the company submitted a provisional application for a patent to the U.S.

Graphene 3D Lab unveils first 3D-printed graphene battery

Patent and Trademark Office for recent innovations in the materials and methods of 3D printable batteries. Yesterday Graphene 3D released a brief video outlining details of the 3D printed battery development. Graphene can be easily mixed with thermoplastics commonly used in FDM 3D printer. Currently the company is working on designing a mixture of plastics and graphene that can be turned into nanocomposite material filament. The key to power any electronic object is to have it attached to a power source. The company's 3D printed graphene battery can potentially outperform a conventional battery because of its shape, size and specifications that can be freely adjusted to fit the particular design of almost any 3D printed device.

Scientists build open-source 3D metal printer

The machines are helping scientists perform experiments in the lab, doctors treat patients, and very soon they'll be helping astronauts build things in space. So far, 3D printing mainly uses different types of plastic filament to build objects, but scientists at Michigan Technological University have come up with a way to expand what can be accomplished with these machines. The team, led by Joshua Pearce, an associate professor of materials science and engineering/electrical and computer engineering, have created an open-source and low-cost 3D metal printer to take on bigger and stronger things.

So far, the machine that lays down thin layers of steel has only made objects like sprockets, but the technology is evolving and you can help it to get better. How to make big things out of small pieces. MIT researchers have developed a lightweight structure whose tiny blocks can be snapped together much like the bricks of a child’s construction toy.

How to make big things out of small pieces

The new material, the researchers say, could revolutionize the assembly of airplanes, spacecraft, and even larger structures, such as dikes and levees. The new approach to construction is described in a paper appearing this week in the journal Science, co-authored by postdoc Kenneth Cheung and Neil Gershenfeld, director of MIT’s Center for Bits and Atoms. Gershenfeld likens the structure — which is made from tiny, identical, interlocking parts — to chainmail. The parts, based on a novel geometry that Cheung developed with Gershenfeld, form a structure that is 10 times stiffer for a given weight than existing ultralight materials.

But this new structure can also be disassembled and reassembled easily — such as to repair damage, or to recycle the parts into a different configuration. Nasa tests 3D-printed rocket engine fuel injector. 15 July 2013Last updated at 08:24 ET Nasa says 3D printing could one day be used by astronauts to make replacement parts Nasa has announced it has successfully tested a 3D-printed rocket engine part.

The US space agency said that the injector component could be made more quickly and cheaply using the technique. The part is used to deliver liquid oxygen and hydrogen gas to an engine's combustion chamber. The news follows General Electric's revelation that it planned to use 3D printing technology to make fuel nozzles for its jet engines. Nasa said that California-based Aerojet Rocketdyne had made the injector using a method called selective laser melting (SLM). TED 2013: 4D printed objects 'make themselves'.

TED 2013: 4D printed objects 'make themselves'

The green 3D printing materials we’ve been waiting for. There’s no denying that 3D printing has moved beyond the laboratory and into the mainstream.

The green 3D printing materials we’ve been waiting for

We’ve seen 3D printed body parts, electronics, and toys. Although the technology has quickly become quite sophisticated, the materials used in 3D printers have been slow to catch up. Though the idea of print-you-own has big green implications, there’s nothing earth-friendly about an uptick in plastic junk floating around the planet. This giant 3D printer can construct a house in as little as 20 hours. While 3D printing might be all the tech geek rage right now, the cooler story is what some people are doing with it to make an actual difference.

We’ve seen stories of medical uses such as new 3D-printed limbs and that’s incredible but USC professor Behrokh Khoshnevis has just blown my mind. Imagine 3D printing on such a large scale, using a concrete-style material, that could “print” a house in as little as 20 hours. Oh, and that material can withstand over three times the PSI force of standard concrete walls. 3-D Printed Car Is as Strong as Steel, Half the Weight, and Nearing Production.

Scientists ‘print’ 3D object with stem cells. By Agence France-PresseMonday, February 4, 2013 21:43 EDT Scientists on Monday said that for the first time they had printed 3D objects using human embryonic stem cells, furthering the quest to fabricate transplantable organs. Once fine-tuned, the technology should allow scientists to make three-dimensional human tissue in the lab, eliminating the need for organ donation or testing on animals, they reported. Human embryonic stem cells (hESCs) can replicate indefinitely and become almost any type of cell in the human body.

They are touted as a source of replacement tissue, fixing nearly anything from malfunctioning hearts and lungs, to damaged spines, Parkinson’s disease or even baldness.

Southampton engineers fly the world’s first ‘printed’ aircraft Ref: 11/75 28 July 2011 SULSA is the world’s first ‘printed’ aircraft.

Engineers at the University of Southampton have designed and flown the world’s first ‘printed’ aircraft, which could revolutionise the economics of aircraft design. The SULSA (Southampton University Laser Sintered Aircraft) plane is an unmanned air vehicle (UAV) whose entire structure has been printed, including wings, integral control surfaces and access hatches. No fasteners were used and all equipment was attached using ‘snap fit’ techniques so that the entire aircraft can be put together without tools in minutes.

The project team worked in partnership with 3T RPD who undertook the manufacture and detailing of the design, as well as supplying laser sintering knowledge and expertise.
