Will 3D Printing Upend Fashion Like Napster Crippled the Music Industry? Before MakerBot, no one could have conceived of Napster for fashion. A Burberry trench couldn't be replicated digitally, which meant the garment industry was more or less safe from the revolution that upended music production and book publishing. But with 3D printing, Fifth Avenue is headed for its own disruptive moment. 3D printers can manufacture spare parts for spacecraft, produce food and housing, even replicate human organs. Simultaneously, the materials used in 3D printers are improving by leaps and bounds, incorporating metals and plastics, wood and nylon. "We are living a world in which fashion and design take on a personal element," says Jonathan Askin, a professor with the Brooklyn Law School and a consultant in Internet law. At the moment, 3D-printed fashion exists mainly in the world of haute couture. As 3D printing evolves, it will introduce new conflicts into the already murky arena of copyright law. "We'll no longer have to buy a suit off the rack and hope it fits.

How to Create a Million-Dollar Business This Weekend (Examples: AppSumo, Mint, Chihuahuas) Noah Kagan built two multi-million dollar online businesses before turning 28. He also looks great in orange. (Photo: Laughing Squid) I first met Noah Kagan over rain and strong espressos at Red Rock Coffee in Mountain View, CA. It would be the first of many. The matchmaker then introducing us was the prophetic and profane Dave McClure, General Partner of 500 Start-ups, which is now headquartered just down the street from Red Rock. Mr. He was employee #30 at Facebook, #4 at Mint, had previously worked for Intel (where he frequently took naps under his desk), and had turned down a six-figure offer from Yahoo. The purpose of this post is simple: to teach you how to get a $1,000,000 business idea off the ground in one weekend, full of specific tools and tricks that Noah has used himself. He will be your guide… Enter Noah For some reason, people love to make excuses about why they haven’t created their dream business or even gotten started. We made the original product for Gambit in a weekend.
Open Source Ecology Além da impressão 3D: Microfábrica imprime, fresa e corta Mecânica Com informações da New Scientist - 18/09/2013 A "fábrica doméstica" portátil também ganhou em precisão, permitindo fabricar objetos com maior nível de detalhamento. Microfábrica Nem bem começaram a fazer sucesso, as impressoras 3D estão prestes a receber o primeiro upgrade significativo. Agora elas não apenas são capazes de imprimir objetos, como também podem cortar, entalhar e fresar, ampliando muito o conceito de hardware livre. O melhoramento é tão significativo que Jeremy Fryer-Biggs, que está lançando sua inovação, chamou seu equipamento de Microfábrica. A Microfábrica é uma máquina portátil completa, pouco maior do que uma impressora 3D doméstica. Além do equipamento padrão de impressão 3D, ela incorpora uma série de cabeças de corte e desbaste que podem imprimir, cortar e fresar plásticos, madeiras e alguns metais leves. A máquina pode ser carregada com plásticos de até quatro cores ou dois materiais diferentes. A demonstração do protótipo impressionou.
Building Your Own 3D Printer Big data: The next frontier for innovation, competition, and productivity | McKinsey Global Institute | Technology & Innovation The amount of data in our world has been exploding, and analyzing large data sets—so-called big data—will become a key basis of competition, underpinning new waves of productivity growth, innovation, and consumer surplus, according to research by MGI and McKinsey's Business Technology Office. Leaders in every sector will have to grapple with the implications of big data, not just a few data-oriented managers. The increasing volume and detail of information captured by enterprises, the rise of multimedia, social media, and the Internet of Things will fuel exponential growth in data for the foreseeable future. MGI studied big data in five domains—healthcare in the United States, the public sector in Europe, retail in the United States, and manufacturing and personal-location data globally. 1. 2.

FabLab Maastricht video interview - PlugnMake FabLab Maastricht specializes in 3D printing research. Its aim is to make both tools and materials as affordable as possible. To do that, they avail themselves of the collaboration with companies, universities and research centers. 21-year-old Floris Hoff managed to build his own company, byflow, thanks to the experience acquired within the FabLab. byflow is a foldable 3D printer with interchangeable nozzles, which allows you to print a wide range of materials through a user-friendly interface. Frits Hoff, manager of FabLab Maastricht, told us about the research lines conducted in the Lab, and about the adopted policies of financing and sharing. Could you tell us about FabLab Maastricht and its value for the community? FabLab Maastricht started 4 years ago with not enough money, like a normal FabLab. Finally, we received some funding, from European Union, but also from the local and national government. Now, we are a professional FabLab doing research in affordable 3D printing.
‘Anti-Gravity’ 3D Printer Uses Strands to Sculpt Shapes on Any Surface 3D printers build objects by cross-section, one layer at a time from the ground up—gravity is a limiting factor. But what if it wasn’t? Using proprietary 3D printing materials, Petr Novikov and Saša Jokić say their Mataerial 3D printing system is gravity independent. The duo’s method allows a robotic arm to print objects on floors, walls, ceilings—smooth and uneven surfaces. Novikov and Jokić invented their system (patent pending) in collaboration with the Institute for Advanced Architecture of Catalonia. In contrast to the 3Doodler, Novikov and Jokić’s system is a software-controlled 3D printer. Why is this an improvement on current tech? Novikov and Jokić say, "This method gives us a flexibility to create truly natural objects by making 3D curves instead of 2D layers. Whether the system can print a wide variety of shapes isn't shown in the video. But the concept is cool, and the tech will likely improve. Image Credit: Mataerial
Eventorbot! Open source 3D printer. by eventorbot Eventorbot! Open source 3D printer. Simple with less materials. Frame is made of a single 4' long, 2 1/2" square tube (16 gauge/1.5mm/.0598" thick, cost: less then $20.00). With the design there is less plastic parts, stronger structure, all wires are hidden, and a more appealing/finish look. The unit is supposed to resemble a robotic arm with hydraulic tubes. For those who do not have access to a 3D printer. Eventorbot has met its funding goal! Well, I'm speechless and overwhelmed with all the support. Thank you... thank you... thank you... Big Data's Management Revolution - Erik Brynjolfsson and Andrew McAfee by Erik Brynjolfsson and Andrew McAfee | 10:05 AM September 11, 2012 Big data has the potential to revolutionize management. Simply put, because of big data, managers can measure, and hence know, radically more about their businesses, and directly translate that knowledge into improved decision making and performance. Of course, companies such as Google and Amazon are already doing this. After all, we expect companies that were born digital to accomplish things that business executives could only dream of a generation ago. We’ve seen big data used in supply chain management to understand why a carmaker’s defect rates in the field suddenly increased, in customer service to continually scan and intervene in the health care practices of millions of people, in planning and forecasting to better anticipate online sales on the basis of a data set of product characteristics, and so on. Case #1: Using Big Data to Improve Predictions Minutes matter in airports. More >>

Silkworms work with robot to make 3D-printed dome | Crave - CNET A dome has been created by teaming up a 3D-printing head on a robotic arm — and a swarm of 6500 silkworms. Animals can do some amazing things, and their behaviours or physical properties have inspired some ground-breaking tech. But what if we could do more with what animals make? But by far one of the most productive animals we use is the silkworm. In order to explore the potential relationship between digital and biological fabrication, MIT Media Lab's Mediated Matter research group has created a project called Silk Pavilion — a 3.65-metre diameter dome that is a collaboration between human designers, machines and grubs. The robotic arm, onto which was attached a 3D printer head, created the primary structure. When the dome's skeleton was completed, 6500 silkworms were positioned on the bottom rim of the scaffolding, filling in the empty spaces with a raw silk canopy. Tiny magnets were placed on the silkworms' heads in order to motion-track their movement as they built their cocoons.
