World's first 3D-printed titanium bicycle frame could lead to cheaper, lighter bikes

World's first 3D-printed titanium bicycle frame could lead to cheaper, lighter bikes
The MX-6 Evo mountain bike, sporting its 3D-printed titanium frame Image Gallery (3 images) When it comes to a high strength-to-weight ratio, titanium is just about the best material out there for manufacturing bicycle frames. Renishaw, an additive manufacturing firm, joined forces with Empire Cycles to build the one-off titanium MX-6 Evo mountain bike. The frame was built using an AM250 laser melting machine manufactured by Renishaw. Because titanium has a higher density than aluminum, less of it had to be used if Empire wanted a finished bike that was lighter than the stock model. As a result, at a total of 1,400 grams (3 lb), the finished Evo frame weighs 33 percent less than its aluminum counterpart. So, how could this project lead to cheaper titanium frames? It should also be relatively simple to tweak frame designs as needed, or to add custom features to individual frames.

L'homme moderne continue de plier des vélos Les designers ne cessent de réinventer les mille et une manières de plier un vélo destiné à la circulation urbaine, en attendant que celle-ci devienne un peu moins dangereuse pour être vraiment pratiquable. Et maintenant, ils savent même plier les roues: Tout ceci semble très convaincant, mais vous n’aurez peut-être pas envie que cette image vous revienne au moment où vous serez en train de pédaler comme un dératé entre un bus et un taxi à une intersection encombrée. Car elle vous rappellerait la réalité: ces quelques kilogrammes de métal, de plastique et de caoutchouc sont la seule chose qui vous distingue du bitume sur lequel vous roulez. [Treehugger via DVICE] China’s Huge 3D Printers, Soon Able to Print Automobile Sized Metal Objects One of the biggest possible economic impacts of 3D printing to the U.S. economy is the fact that it may eventually allow corporations to bring jobs back onshore from China. The United States outsources a large number of jobs over to Asia as a way to cut labor costs. 3D printing and robotics promises to change some of this, as companies can utilize industrial scale 3D printers and automation to manufacture parts for their products, cheaper than even the labor force in China can produce them. That’s if, of course China lags behind in their adoption of these technologies. It appears, however that China is investing heavily in 3D printing, just like those in the U.S. and Europe. Their corporate and government leaders clearly can identify an emerging technology and its possible economic impact on the future of China. In fact, back in June, China announced a gigantic 3D printer, which they claimed was the world’s largest at the time, with a 1.8 m build diameter.

Your next bike could be made from folded sheet metal - Images Go into any bicycle store, and pretty much all of the bikes in there will have frames made from metal tubes or carbon fiber. A few manufacturers have gotten a bit more adventurous, offering frames made of bamboo or wood, while some have even experimented with things like aramid panels and nylon. A trio of San Francisco-based entrepreneurs, however, have created a prototype bicycle using yet another frame material – hand-folded sheet metal. They claim that their product is lighter, stronger and cheaper to produce than an aluminum-tube frame, and they’re hoping to be able to sell you one. View all Rob, Mark and Andy are three mechanical engineers, who make up the company known as Ronin Metal Masters. After some experiments using heavy stock paper, the current prototype was built out of 0.024 inch (0.6 mm)-thick 6061-T6 aluminum. While the frame certainly has a unique “iron bridge” look to it, the choice of material goes beyond aesthetics. Source: Ronin Bicycle Works

EBIKE 72v - X5404 Genesis Farfle build Pt1 Programmable Matter: Claytronics or Gershenfeld We still tell our children “you can be anything when you grow up.” It’s time to start telling them “you’re going to be able to make anything…right now.” Similar work at MIT and Carnegie Mellon is pointing towards the next revolution in computers and manufacturing: programmable matter. In the future you won’t use computers to design a car, the car will form from billions of tiny computers that arrange themselves into anything you want. The physical and computational world will merge. Claytronics is developing tiny computers that can work together to form shapes. How can a material be intelligent? Carnegie Mellon isn’t the only university pursuing intelligent materials. It All Looks Good on Paper It would be amazing if these technologies were available today, but they are still a long way off. In hardware, Claytronics has already made centimeter sized cylindrical catoms that have basic features. To test Catom forces without gravity, helium filled prototypes are used.

BriTek's Brilliant Airless Bicycle Tire Reinvents the Wheel Flat bicycle tires could be a thing of the past thanks to BriTek‘s amazing new Energy Return Wheel. Whereas most bike tires regulate tire firmness with air pressure, with the Energy Return Wheel one simply adjusts the tension of the rubber that is stretched around a 29-inch carbon fiber wheel. Initially tested on cars, the airless tire is comprised of two layers of rubber – one at the center, stretched and held by adjustable rods, and the other on the outside. The space between, usually filled with air, holds a series of elastic cushions. The internal scaffolding of rods and cushions allow the tire go give and, according to Britek, react better to compression. The Energy Return Wheel is still being tested (the company is considering adding thin sidewalls to the fiber rims, to keep mud and trail debris from piling up within them). + Energy Return Wheel Via NBC News

ROTWILD Bikes - THE NEW ROTWILD GT S INSPIRED BY AMG Lightweight construction, dynamics, design and comfort – that’s what the ROTWILD GT S inspired by AMG stands for. The efficient thoroughbred special edition racer is limited to 100 models and perfectly combines high performance materials with refined chassis technology and a unique design. Development has incorporated the professional feedback of the AMG ROTWILD MTB Racing Team, preparing the bike for the most challenging mountain bike race circuits. Already during the early stages of development, the ROTWILD GT S inspired by AMG proved its exceptional qualities by winning a Junior’s World Championship title. After the full-suspension carbon mountain bike R.X45 AMG, the ROTWILD GT S inspired by AMG is the second mountain bike presented by ROTWILD and Mercedes-AMG. With the new model, the sports car and performance brand of Mercedes-Benz and the internationally renowned high-end mountain bike manufacturer take their collaboration to the next level.

Autopoietic Computing | DarkAI Blog Proposed by: on 12/30/2013 Reality augmented autopoietic social structures A self replicating machine is a machine which can make a copy of itself. Just as biological entities have DNA which operates on the same principle of self replication, the same fundamental process which takes place in biological organisms can take place in artificial lifeforms. Self replication of a reality augmented autopoietic social machine can be facilitated by many different methods. In order for an idea to replicate itself it must encourage itself to be copied and if we consider the essence of the decentralized autonomous corporation to be a general idea then the entire family of DACs all belong to the same family of ideas, the same family tree, and trace back to the same source. The protochain could just as easily have been called a seedchain. “Biological seeds grow into larger organisms using local matter and energy, and eventually produce copies of the original seed.
