Eco-friendly 3D printed supercar

A California automotive start-up is hoping their prototype supercar will redefine car manufacturing. The sleek race car dubbed ‘Blade’ didn’t come off an assembly line – but out of a 3D printer.

Kevin Czinger of Divergent Microfactories has spent most of his career in the automotive industry. One day he realized that no matter how fuel-efficient or how few tailpipe emissions the modern car has, the business of car manufacturing is destroying the environment.

“3D printing of metal radically changes that. By looking at 3D printing not for that overall structure but to create individual modular structures that can be combined, that 3D printing transforms everything,” said Czinger during an interview with Reuters in Silicon Valley.

According to Czinger, 3D printing transforms everything by changing the way the structural components of cars are fabricated. Currently cars are pieced together on long assembly lines inside large factories that use massive amounts of energy. Even the most fuel-efficient car has a large carbon footprint before ever leaving the plant.

Czinger and his team’s approach was to take the large plant out of the equation. To accomplish this they printed the modular pieces that are used to connect carbon rods that make up the Blade’s chassis.

“The 3D printed chassis is only 102 pounds and has the same strength and safety protection as a frame made out of steel,” said Brad Balzer, the lead designer on the project.

By using carbon fiber instead of steel or aluminum for the body, the entire vehicle only weighs 1400 pounds (635kg), giving it twice the weight to horsepower ratio of a Bugatti Veyron.

The Blade is fitted with a 700 horse power engine that runs on natural gas, reducing its carbon footprint even further.

Balzer says designing an eco-friendly speed demon supercar as their first prototype was intentional.

“We focused a lot on the aesthetics of this car because it is very important to capture the people’s imaginations, especially when we are talking about the core enabling technologies,” he said.

The core enabling technology, the ability to print out car components that can be easily assembled, is what Kevin Czinger hopes will revolutionize car manufacturing. He says electric cars are a step in the right direction, but alone they won’t be enough to curb greenhouse emissions given the projected rise in demand for cars globally unless the way they are manufactured changes.

“By constructing a car this way it has less than one third of the environmental and health impact than the 85 hours all electric car for example has,” he added.

Czinger and Balzer are starting small but they believe their new 3D printing method for car manufacturing will have a huge impact on how the cars of the future are built.

A Dutch Woodworker Has Created an Eco-Friendly Bicycle Created Entirely Out of Aluminium and Wood

Oh, the joys of cycling — and of collecting bikes. If you know a bicycle enthusiast (or are one), you are probably aware they rarely just have one, and if said person lives in a city they usually have several bikes meant for every cycling scenario imaginable piled up in their living room, kitchen, or bedroom for safekeeping. Moving them or paring down the collection is simply not a thought that has crossed their minds whatsoever as they might need a commuter, a mountain bike, a hybrid, or a more customized bike that’s lighter in weight for going greater distances.

If you live with someone who is encroaching on your space with bikes, the advent of 3D printing might be even greater cause for you to worry if they are handy and technically savvy. The bikes could begin multiplying, as they 3D print out parts in delight, with Amsterdam designer Paul Timmer as the perfect role model.

Timmer has recently designed and built a bicycle completely out of wood and 3D printed aluminum parts. Timmer, obviously not just a woodworker and cyclist, but also a great artist, has constructed a streamlined design with the innovative technology of 3D printing and the superior quality of solid ash.

Featuring an extremely eco-friendly design — not to mention all recyclable — with the aluminum parts and solid ash wood, the bike weighs in at a mere 11 kilograms, which is equal to 24 lbs or so. This makes a normally constructed bike seem pretty clunky in contrast to Timmer’s sleek design, which is meant as an all-terrain means of transportation.

While not the only creatively constructed wooden bike on the market for sure, Timmer’s is the only one (that we know of so far) that employs 3D printed aluminum parts as a means of stability and added strength.

“The main advantage of the wooden frame is the exceptional comfort. All vibrations, due to bumps in the road, are instantly absorbed,” said Timmer. “Wood is the best construction material available. This bike can be as strong as a steel one, but it has to be designed better than a steel one.”

Why does someone stray off the beaten path so far with these types of materials for a bike? Timmer wanted a top-of-the-line ride and he just so happened not only to know how to build one but also how to create custom 3D designs for everything on the bike that wasn’t wood, and he had the resources to 3D print them.

Using ‘forks’ to form a triangle from the handlebar area down to the mechanics of the 3D printed chain, which is made out of a clean belt drive, keeps the wood grain as pristine as possible, and increases durability. As Timmer states on his website, the bike “becomes strong enough by extraordinary attention to detail.”

With 3D design, Timmer was afforded the freedom to tweak and refine parts and 3D print them out as needed rather than having to order something or rely on someone else to make it. That’s the beauty of 3D design and 3D printing as we know it. And while this design is currently the only one of its kind, Timmer has plans to produce them for other biking — and 3D printing — enthusiasts soon.

Is this a bike that interests you for your cycling needs? How do you think the combination of wood and 3D printed aluminum parts can be more helpful? Tell us your thoughts in the 3D Printed Bicycle with Wood forum thread over at 3DPB.com.
