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.

3D-printed hip implant lets teenager walk again The 3D-printed implant that has given a once wheelchair-consigned teenager the ability to walk on her own Image Gallery (2 images) Much of the fanfare surrounding 3D printing has centered on its enabling consumers to create objects themselves, potentially circumventing traditional production models. Alongside NBA figurines and 3D printed pizza, however, the technology continues to provide valuable solutions in the field of medicine. The 15-year old Swedish girl suffered from a congenital disease which saw a neurofibroma, a benign tumor which grows on the peripheral nervous system, cause extensive damage to her pelvis. Professor Rydholm of Skane University Hospital in Lund, Sweden, who was looking after the case, approached Mobelife, which on its website describes itself as "a specialist in implant design and production for challenging bone and joint reconstruction surgery." Mobelife then set to work in creating the custom implant. Source: Mobelife, Reuters About the Author

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.

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] 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

MakeVR brings motion control to 3D modeling Though 3D printers themselves are becoming more affordable, the complexities of 3D modeling software have also proven a hurdle to entry to the consumer market. While some companies have sought to enhance their mainstream appeal with catalogs of pre-designed printable objects, others are taking a more hands-on approach. Virtual reality firm Sixense, which this week announced its motion controlled solution for 3D modeling called MakeVR, hopes to make the design process more intuitive and appealing for the average user. View all Launched on Kickstarter on Wednesday, MakeVR is a 3D modeling system comprising two components: a CAD engine that the company describes as professional-grade, and Sixense's 3D multi-touch interface which uses specially designed STEM System Controllers. Tracking both hands independently, MakeVR's motion control allows users to design their 3D models through two corresponding cursors on-screen. Sources: Sixense, Kickstarter

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.

EBIKE 72v - X5404 Genesis Farfle build Pt1 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

The Mark One Carbon Fiber 3D Printer We took a look at a surprise 3D printer unveiled this week: Mark Forg3D’s Mark One, after a year of secret development work. At a glance, it looks like any other personal-sized 3D printer, albeit with a very slick metal case. But then you look at what’s being printed. Carbon Fiber. Yes, this device can actually 3D print carbon fiber. Carbon fiber produced by the Mark One is said to be 20X stronger than ABS - and even slightly stronger than aluminum! We were surprised to learn that you don’t need to 3D print objects made entirely of carbon fiber. According to Mark Forg3D, a typical part would be printed in a combination of nylon and carbon fiber. The Mark One has another very unique feature: it’s removable print bed has capabilities we’ve not seen before. The Mark One has a very healthy 305 x 160 x 160mm build volume and can manage up to 0.1mm accuracy.

Drymer Meet The 17-Year-Old Who Created A Brain-Powered Prosthetic Arm Easton LaChappelle’s story offers a reminder of the simplest key to success--if you want something badly enough, do the work and find creative ways to achieve your desired outcome. If traditional systems aren’t providing what you need to accomplish your mission, then break away--break away from your 9-5 job, break away from the agenda that’s set by conventional mind-sets. Easton broke away from the limitations of the public education system and taught himself what he wanted to know. For LaChappelle, this meant learning how to build a better prosthetic arm. “I tested a need in the market with a Kickstarter campaign. LaChappelle’s mission is to reinvent conventional prostheses. Living in a small town in Colorado, LaChappelle has had to self-teach himself everything--electronics, coding, how to use a 3-D printer, the list goes on. The first version was a wireless hand that was controlled by a glove.
