The Green 3D Printing Materials We’ve Been Waiting For

by

Eerth Techling

There’s no denying that 3D printing has moved beyond the laboratory and into the mainstream. 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. That’s why we’re so excited about the work of Emerging Objects, a two-architect outfit that teaches 3D printing in Berkeley. Founders Ronald Rael and Virginia San Fratello are working to move the trend away from plastic and toward far more sustainable materials like wood, salt, and clay.

“Emerging Objects is interested in the creation of 3D printed buildings, building components and interior accessories that can be seen as sustainable, inexpensive, stronger, smarter, recyclable, customizable and perhaps even reparable to the environment,” write the architects. “We want to 3D print long-lasting performance-based designs for the built environment using raw materials that have strength, tactility, cultural associations, relevance and beauty.”

Micro Manufacturing, Third Wave Style…Perfect for Worker Coops?

In the Next Industrial Revolution, Atoms Are the New Bits

By Chris Anderson

The door of a dry-cleaner-size storefront in an industrial park in Wareham, Massachusetts, an hour south of Boston, might not look like a portal to the future of American manufacturing, but it is. This is the headquarters of Local Motors, the first open source car company to reach production. Step inside and the office reveals itself as a mind-blowing example of the power of micro-factories.

In June, Local Motors will officially release the Rally Fighter, a $50,000 off-road (but street-legal) racer. The design was crowdsourced, as was the selection of mostly off-the-shelf components, and the final assembly will be done by the customers themselves in local assembly centers as part of a “build experience.” Several more designs are in the pipeline, and the company says it can take a new vehicle from sketch to market in 18 months, about the time it takes Detroit to change the specs on some door trim. Each design is released under a share-friendly Creative Commons license, and customers are encouraged to enhance the designs and produce their own components that they can sell to their peers.

Here’s the history of two decades in one sentence: If the past 10 years have been about discovering post-institutional social models on the Web, then the next 10 years will be about applying them to the real world.

This story is about the next 10 years.

Berto Jongman: 4D Printed Objects Self-Assemble

TED 2013: 4D printed objects ‘make themselves’

Many are only just getting their heads around the idea of 3D printing but scientists at MIT are already working on an upgrade: 4D printing.   At the TED conference in Los Angeles, architect and computer scientist Skylar Tibbits showed how the process allows objects to self-assemble.  It could be used to install objects in hard-to-reach places such as underground water pipes, he suggested.  It might also herald an age of self-assembling furniture, said experts.

Smart materials

TED fellow Mr Tibbits, from the MIT’s (Massachusetts Institute of Technology) self-assembly lab, explained what the extra dimension involved.  “We’re proposing that the fourth dimension is time and that over time static objects will transform and adapt,” he told the BBC.  The process uses a specialised 3D printer that can create multi-layered materials.  It combines a strand of standard plastic with a layer made from a “smart” material that can absorb water.  The water acts as an energy source for the material to expand once it is printed.  “The rigid material becomes a structure and the other layer is the force that can start bending and twisting it,” said Mr Tibbits.

Open Access: a remedy against bad science

Who has never been in the situation that he had a set of data where some of them just didn’t seem to fit. A simple adjusting of the numbers or omitting of strange ones could solve the problem. Or so you would think. I certainly have been in such a situation more than once, and looking back, I am glad that I left the data unchanged. At least in one occasion my “petty” preformed theory proved to be wrong and the ‘strange data’ I had found were corresponding very well with another concept that I hadn’t thought of at the time.

3-D Printed Car Is as Strong as Steel, Half the Weight, and Nearing Production | Autopia | Wired.com

Kor and his team built the three-wheel, two-passenger vehicle at RedEye, an on-demand 3-D printing facility. The printers he uses create ABS plastic via Fused Deposition Modeling (FDM). The printer sprays molten polymer to build the chassis layer by microscopic layer until it arrives at the complete object. The machines are so automated that the building process they perform is known as “lights out” construction, meaning Kor uploads the design for a bumper, walk away, shut off the lights and leaves. A few hundred hours later, he’s got a bumper. The whole car – which is about 10 feet long – takes about 2,500 hours.
