Time for Monumental Thinking in Additive
Karen Haywood Queen for AdvancedManufacturing.org: The limits of CAD and CAE tools and the STL file format are holding manufacturers back
As additive manufacturing emerges from a long infancy, the industry is grappling with a key challenge: A file format and design tools from the 20th century are being asked to do 21st century jobs.
“The industry was a hobby industry for 25 years and it’s starting to grow up,” said Kirk Rogers, technology leader at GE.
“You made a 3D model and it had a cool factor—Mickey Mouse or a little chess piece—it was awesome to look at,” said Kenneth Church, CEO of the R&D engineering firm Sciperio, as well as the 3D printing firm nScrypt. “What if I made it functional? Cont'd...
With 3D printers and nanofingers, HP Labs builds a new future
Stephen Shankland for CNet: Get ready for the third chapter in the book of Silicon Valley.
During the first chapter, innovation in Silicon Valley was about atoms, carving up silicon wafers into the electronic transistors that started the computing revolution. The second one, more ethereal, brought the triumph of internet services like Facebook and Google.
To be competitive now, a company must blend both approaches. That's the view of HP Chief Engineer Chandrakant Patel, who rose through the HP Labs ranks over 30 years to secure 151 patents and become the company's chief engineer.
"The 21st century will require Silicon Valley to be a cyber-physical valley," Patel said. Cont'd...
3D printing hack: Researchers crash drone with sabotaged propeller
Conner Forrest for TechRepublic: University researchers were able to sabotage a drone by hacking the computer controlling the 3D printer that made its parts, according to a research paper released Thursday. By changing the design of the propellor before printing, they caused the $1,000 drone to "smash into the ground" and break, shortly after take off.
The paper, titled dr0wned - Cyber-Physical Attack with Additive Manufacturing, was a joint effort from researchers at Ben-Gurion University of the Negev (BGU), the University of South Alabama, and Singapore University of Technology and Design. In the paper, the researchers explained how they committed the cyberattack, and what the attack could mean for the future of 3D printing security.
Using a phishing attack, the researchers gained access to the PC that was connected to the 3D printer. Cont'd...
GE opening microfactory in Chicago to build industrial prototypes
Robert Channick for the Chicago Tribune: GE is opening a microfactory in Chicago to turn big industrial ideas into small-batch prototypes. The Chicago manufacturing facility, set to open in December, will be the first for Fuse, a new GE crowdsourcing initiative to create and build innovative industrial products. One of the first challenges on the Fuse drawing board, for example, is finding a new way to quickly inspect a hot jet engine between flights.
"The idea of reaching out to the online community really accelerates how we introduce new products," said Axel Grippo, Fuse's inaugural general manager. The microfactory will be housed inside the mHub technology incubator, and will employ a staff of about 15 to 20 once manufacturing gets up to speed, Grippo said. The first prototype is expected to roll out early next year. Cont'd...
Give a 3D printer artificial intelligence, and this is what you'll get
Dyllan Furness for Digital Trends: A London-based startup has combined some of today’s most disruptive technologies in a bid to change the way we’ll build the future. By retrofitting industrial robots with 3D printing guns and artificial intelligence algorithms, Ai Build has constructed machines that can see, create, and even learn from their mistakes.
When CEO and founder Daghan Cam was studying architecture, he noticed a disconnect between small-scale manufacturing and large-scale construction. “On one side we have a fully automated production pipeline,” Cam explained at a recent conference in London. “On the other side we’re completely dependent on human labor.” With the emergence of more efficient printing technologies, he thought there must be a better way.
“We wanted to push the boundaries of how intricate we could design things through computation and how we could create them through 3D printing,” Cam said. Cont'd...
MIT's Foundry software is the 'Photoshop of 3D printing'
Andrew Dalton for enGadget: Because the materials from a 3D printer aren't the most functional, their output has largely been limited to prototyping in the past. That should change in the near future with devices like MIT's own MultiFab, which can print up to 10 different materials at a time, but it still doesn't solve the problem of how to design such complex objects. That's where the new program called Foundry, created by MIT's Computer Science and Artificial Intelligence Laboratory comes in.
According to MIT CSAIL, Foundry can import objects designed with traditional CAD programs like SolidWorks and then assign specific materials or properties to different parts of the object. While creating a multi-material object in the past might have required days of work and multiple 3D printers to create (assuming it was possible with existing technology at all), CSAIL says these sorts of designs can now be created in mere minutes. Rather than manufacturing a separate piece for each material in the finished product, the entire object can now be printed in one fell swoop. Cont'd...
Blockchain plus 3D printing equals 'smart manufacturing' and Ethereum you can touch
Ian Allison for International Business Times: Genesis of Things is a new "smart manufacturing" company which leverages intellectual horsepower from members of the Ethereum community.
This young company, established and launched just a few weeks before DevCon2 in Shanghai, has produced a tangible proof of concept in the form of a set of 3D printed titanium cufflinks inscribed with a QR code and bearing the insignia of the Ethereum logo.
Genesis of Things combines 3D printing, blockchain and IoT in a virtuous, futuristic flow that re-imagines manufacturing processes. The company is in stealth right now and more details about how it operates and possible use cases will be released going forward.
It should be repeated that the cufflinks pictured are a proof of concept; this is not a commercial product but rather a limited edition to show the potential of the technology. Cont'd...
3-D-printed robots with shock-absorbing skins
Adam Conner-Simons for MIT News: Anyone who’s watched drone videos or an episode of “BattleBots” knows that robots can break — and often it’s because they don’t have the proper padding to protect themselves.
But this week researchers at MIT’s Computer Science and Artificial Intelligence Laboratory(CSAIL) will present a new method for 3-D printing soft materials that make robots safer and more precise in their movements — and that could be used to improve the durability of drones, phones, shoes, helmets, and more.
The team’s “programmable viscoelastic material” (PVM) technique allows users to program every single part of a 3D-printed object to the exact levels of stiffness and elasticity they want, depending on the task they need for it. Cont'd...
Metamaterial Mechanisms
From the Hasso Plattner Institute:
Recently, researchers started to engineer not only the outer shape of objects, but also their internal microstructure. Such objects, typically based on 3D cell grids, are also known as metamaterials. Metamaterials have been used, for example, to create materials with soft and hard regions.
So far, metamaterials were understood as materials—we want to think of them as machines. We demonstrate metamaterial objects that perform a mechanical function. Such metamaterial mechanisms consist of a single block of material the cells of which play together in a well-defined way in order to achieve macroscopic movement. Our metamaterial door latch, for example, transforms the rotary movement of its handle into a linear motion of the latch. Our metamaterial Jansen walker consists of a single block of cells—that can walk. The key element behind our metamaterial mechanisms is a specialized type of cell, the only ability of which is to shear.
In order to allow users to create metamaterial mechanisms efficiently we implemented a specialized 3D editor. It allows users to place different types of cells, including the shear cell, thereby allowing users to add mechanical functionality to their objects. To help users verify their designs during editing, our editor allows users to apply forces and simulates how the object deforms in response... (project homepage)
How to Attract Millennials to Advanced Manufacturing Jobs
Tony Oran for Quality Digest: In an age where popular technology careers are only seen as attractive if they are based in Silicon Valley or offered by the latest and greatest startup companies, the manufacturing industry must make changes to attract bright and talented Millennials. The numbers clearly illustrate this need.
Baby Boomers currently make up a large part of the manufacturing workforce. With many workers expected to retire in the coming decade, there will be nearly 3.5 million jobs to fill, according to Deloitte and the Manufacturing Institute. Millennials have now overtaken Baby Boomers as the most populous generation, making them one of the largest pools of talent for employers. Quantity, however, does not always translate to quality.
Employers are struggling to find qualified workers to fill available openings, and it’s a trend companies are seeing regardless of sector. Cont'd...
Home 3D Printing 'Just Not There Yet' Admits MakerBot
Alex Cranz for Gizmodo: MakerBot was going to change the world. It was going to bring 3D-printing, long a product limited to designer offices and workshops, into the home (or at least the garage). But earlier today, under a veil of marketing speak and glitzy videos, the company announced a new focus on commercial—not consumer—products, and in so doing, finally admitted what we’ve all known for a while. No one really wants a 3D printer in their house.
CEO Jonathan Jaglom called MakerBot’s event an “an overall repositioning” for the brand. That’s a market savvy way of saying MakerBot is abandoning the home and hobbyist and embracing offices and schools. Later, when I asked about MakerBot’s former dream of getting 3D printers into people’s homes Jaglom’s answer seemed to come easily, the consumer market’s “just not there yet.” Cont'd...
New modular AM 'smart factory' from Concept Laser decouples pre-production and production
Benedict for 3Ders.org: German metal 3D printing specialist Concept Laser has unveiled its new "smart factory" approach to additive manufacturing. The idea behind the Industry 4.0 "smart factory" is to decouple process stages, allowing tasks to be carried out in parallel and physically separate from one another.
The AM Factory of Tomorrow, Concept Lasers modular additive manufacturing factory-building kit, has been designed to allow manufacturers to seamlessly incorporate additive manufacturing technologies into existing production lines or to develop new and efficient AM production spaces. The Lichtenfels-based company has now revealed new aspects of its advanced manufacturing concept, detailing how a move from the sequential to the parallel could maximize production speed, cost-efficiency, and scalability.

Peugeot Teams Up With 3D Printing Startup for Parts and Possibly Full Cars
Daniel Bentley for Fortune: French carmaker PSA said on Thursday a partnership with a U.S. 3D printing startup would lead to cheaper production of whole vehicle structures as well as parts for its models.
The maker of Peugeot, Citroen and DS cars said it had agreed with Los Angeles-based Divergent 3D to develop metal printing processes for PSA production lines.
Carlos Tavares, PSA’s chief executive, said this could “dramatically scale down the size and scope of our manufacturing footprint” and yield lighter, more profitable vehicles. The carmaker did not quantify any impact on production jobs.
Industries from aerospace to healthcare use 3D printing for the production of metal and plastic components, while elaborate assemblies with moving parts often prove more difficult. Ford is among other carmakers exploring the technology. Cont'd...
3D printed designs easily stolen by nearby smartphone
Jack Loughran for E&T: 3D printers have been shown to be vulnerable to attack by smartphones that can steal designs by being within close proximity during the printing process.
A study from the University at Buffalo, USA explored security vulnerabilities in 3D printing, also called additive manufacturing, which analysts say will become a multibillion-dollar industry employed to build everything from rocket engines to heart valves.
"Many companies are betting on 3D printing to revolutionise their businesses, but there are still security unknowns associated with these machines that leave intellectual property vulnerable," said assistant professor Wenyao Xu, who worked on the project. Cont'd...
GE speeds up 3D printing push with bids for SLM, Arcam
Johannes Hellstrom and Maria Sheahan for Reuters: General Electric launched bids on Tuesday to buy two of the world's top makers of machines for metal-based 3D printing - Sweden's Arcam and Germany's SLM Solutions - for a total $1.4 billion to bolster its position in the fast-growing technology.
