What Is 3D printing and prototyping?

Nowadays, more or less everyone has heard about 3D printing to some extent. It’s used all over the world by individuals or big companies to transform computer models to real-life objects. For a bike R&D and manufacturing company like FuroSystems, 3D printing is vital in order to be able to iterate fast between designs while keeping prototyping costs low. It was essential in bringing the FX, the SIERRA and the L1 to life. But how does it work exactly?

What Is 3D Prototyping?

When designing a new part or component, engineers use CAD (Computer Aided Design) software such as Solidworks or Autodesk Inventor. These allow creating shapes and patterns which aggregate to solid 3 dimensional objects. The CAD software then allows saving this object in the form of an STL file which basically maps the surface of the object with triangles. This file is then uploaded to the 3D printer which reads it and proceeds to create the object vertically layer by layer following different processes described below.

Extrusion deposition is the method employed by most desktop 3D printers and consequently the most widely used in 3d printing. Here, a filament of thermoplastic (most common) or metal is passed through a heated nozzle to melt, deposit on a surface and harden instantly. The nozzle turns the flow of material on and off while motors displace it according to the 3d coordinates contained in the STL file.

Another process consists in the binding of granular materials. Powders of materials such as metals or plastics are deposited on a bed. Powerful lasers or binding agents are then applied to it according to the model’s coordinates to fuse and harden the beads layer by layer, starting from the bottom and progressing upwards. Technologies using this process are Selective Laser Sintering (SLS), Direct Metal Laser Sintering (DMLS), Selective Laser Melting (SLM) or Electron Beam Melting (EBM).

Photopolymerisation is also an interesting 3D printing technique. Processes such as Stereolithography (SLA) are based on the hardening of liquid materials into solid shapes. Here, baths of liquid polymers with photosensitive additives are exposed to controlled lighting which leads them to harden. Again, this process is applied from bottom to top through little increments where the shape being built is slowly displaced downwards as new material is solidified. This technique allows to obtain smoother plastic surfaces and therefore reduce the need for part post-processing (smoothening, etc).

Advantages of 3D Printing for Prototyping

In the end, 3D printing is a real revolution in hardware development. It allows materialising designs at record speeds and with similar aesthetic properties to finished products. Of course, engineering characteristics such as strength cannot be similar to those in properly manufactured products but they are sufficient to test shapes, details and configurations before moving to the factory machinery. In turn, 3D printing saves designers considerable amounts of time and money and enables smaller entities to come up with great products and compete with the big guys, often less inclined to innovate from their comfortable leading position.

Why an eBike is so good for commuting

This is going to sound cliché, but FuroSystems genuinely started from the following thought: what are some of the biggest problems in our society right now? And can the latest technologies combined with clever engineering solve them?The global population is growing which with urbanisation is causing population densities around cities to increase. In addition, personal transportation systems such as cars, vans and motorcycles are bulky and noisy. Add to that the fact that about a century ago, we chose fossil fuels over electricity (rightly so at the time), we now have a nice combo of polluting, traffic stimulating and impractical vehicles. As this has even become deadly, we urgently need something better.

Traffic Jam

At FuroSystems, we really think that the clear solution is electric bicycles. They are now powerful enough and offer sufficient autonomy to take a rider anywhere, around any city in the world, for multiple days. They are compact, fast, quiet and clean. This is why we decided to use our expertise to help accelerate our society’s transition to this amazing and fun mode of transportation. How? By making them better, more practical, more attractive and more affordable.

As with any great innovation, electric bikes have their sceptics, the main argument is that it’s essentially a way to cheat cycling, something for the lazy.

According to Steve Garidis, the UK’s Bicycle Association’s operations director: “It’s quite difficult to explain what [an ebike] feels like: you’re still cycling but it’s like being an Olympic athlete; you can go faster and longer; hills are less effort. The acceleration is quite fun, even for the most sceptical grown up.”

So yes, ebikes do make it easier. They allow older or handicapped people to go places they can’t anymore or never could, and ride with their loved ones. It makes commuting and cycling more manageable. However, they also allow everyone else to experience a new level of acceleration, speed and performance. They don’t remove the effort if you still want it, they just make everything better, more intense, it’s an enhancement of your physical capacities whether you are fit or not. For example, our bikes the SIERRA and the FX give you the option of riding them unpowered making them feel exactly like normal bikes, but they also allow you to multiply your acceleration, uphill capacity and speed, whenever you feel like it. To make it even simpler, they are a 250 W to 600W power add on to your body which you can choose to activate on demand.

Deciding to use an ebike for your commute instead of your car, scooter or moped is probably the best thing you could do today. No more pollution, no more noise, no more fuel, no more insurance and a healthier lifestyle. Folding bikes like the FX are also incredibly more practical, particularly when they are that light while staying very powerful and offering great range, not far off from that of a 50cc petrol scooter.

Electric bicycles are the mode of transportation of the future, they literally solve every single problem you could think of in modern transportation and greatly enhance cycling. In addition, battery technology is close to making significant leaps forward with technologies such as solid-state chemistry, supercapacitors or 2D materials such as graphene. You can trust that we will be here to implement each of these advances in your FuroSystems ebikes as soon they are out!

A little eye candy for those of you that stayed with us to the end 🙂

Carbon Fiber: the wonder material explained

Most of you will have heard about it. Carbon fiber, the wonder material that makes everything lighter and stronger. It’s used in supercars, aerospace machinery and the FuroSystems SIERRA and FX (could we call them superbikes?).FuroSystems FX Full Carbon Fiber Folding Ebike

So what is it? Its basic element is carbon, it’s made of 6 electrons, 6 protons and 6 neutrons and without it, you wouldn’t exist, nor would any life on Earth. When you overcook your food or burn some wood, the residual ash is mainly carbon. Carbon fibers consist of these atoms being assembled in crystals and bonded in a direction that is approximately parallel to the fiber’s long axis. Each fiber is between 5 and 10 micrometers (millionths of a meter) wide or 2 to 20 times narrower than a human hair. This configuration gives them a strong strength to volume ratio. Individual fibers are relatively weak on their own but once woven together they lead to a very strong cloth.

Carbon Fiber fibers

At this point, carbon fiber is just a fabric similar to the ones made of cotton for your t-shirts, only much stronger and much more expansive. To transform it into a useful and solid engineering material, the cloth is mixed with a plastic resin such as epoxy to form a composite also called carbon fiber reinforced composite. The manufacturing process usually consists of a technician laying the fibers on a mould, painting them with the chosen resin and then baking the assembly to obtain a part with the desired shape. The result is an extremely rigid and very high strength to weight ratio component.

Carbon fiber reinforced composites (CFRP) are about ten times stronger and 5 times lighter than steel and eight times stronger while 2 times lighter than aluminium. In addition, their very manufacturing removes the need for welds and allows for sleeker and smoother shapes. CFRP indeed tend to be more brittle and crack slightly more easily than aluminium or steel. However, this is easily compensated through design by ensuring that the load necessary to lead to a crack will always be much larger (MUCH LARGER) than the greatest load your bike will ever experience during its use.

Also, the fact that carbon frames cannot be fixed once broken is a myth, they absolutely can, in a very rapid and discreet way as well. After all, if it’s trusted to make the wings of giant machines that fly hundreds of km in the sky, costing hundreds of millions of dollars and carrying hundreds of people (that’s a lot of hundreds), then it can most likely be used to enhance your biking experience, and that’s exactly what we’ve done. Aerospace engineering at the service of happy riders!
