HEXR: A 3D Printed Bike Helmet

Hexr: a 3d printed bike helmet

Irrespective of the place you’re biking, in case you’re biking round a rustic lane or biking in the course of all the town visitors, it’s at all times clever to put on your helmet. Helmets present the person the mandatory safety to stop you from getting harm within the occasion of a fall or crash.

This plastic casing can are available a wide range of shapes, sizes, types, and colours, however all serve to a single goal. Not all helmets are snug for all customers, irrespective of the scale. This results in bike riders to go for not utilizing helmets, growing the possibilities of head accidents, and even worse tragedies.

In Britain, for instance, greater than 100 cyclists are killed and round three,000 are injured yearly for not correctly utilizing their helmets. HEXR is seeking to scale back these numbers. HEXR is a British firm based by Jamie Prepare dinner who, throughout his mechanical engineering diploma at College Faculty London, acquired fascinated by cycle helmets and found that the oft used Expanded Polystyrene (EPS) just isn’t a really perfect materials for affect management. Prepare dinner developed an alternate as he continued his analysis on the College of Oxford as a postgraduate the place he spent the previous three years working along with main lecturers to develop the HEXR helmet.

Though it’s not the primary helmet to be 3D-printed, it nonetheless is the primary to be created from Polyamide 11, which is normally utilized in lots of industries and is named a troublesome materials. In keeping with Prepare dinner, vitality absorption on principally all design strategies relies on a flat contact space, like EPS, which hardens upon affect. HEXR’s Polyamide 11 (PA 11) helmet, nevertheless, it’s made up of hexagonal cells in a honeycomb designed and structured to dissipate the vitality. This helps to unfold the vitality over a bigger space and prevents the chance of a critical harm. The HEXR is claimed to regulate affect 68% greater than EPS constructed helmets.

From the start, Prepare dinner believed that HEXR could possibly be a terrific product each for riders and, in fact, the surroundings. However the greatest problem for Prepare dinner was in manufacturing the helmets and to manufacturing sustainable. Manufacturing a mould for HEXR’s complicated, intricate, and skinny partitions just isn’t simple, low-cost, neither fast with conventional injection molding. And since helmets require a wide variety of sizes to suit each head form, it means extra analysis, time, and exams. He had to decide on between increased prices for extra sizes and security. Fortunately for Prepare dinner, 3D printing can scale back the affect of those disadvantages.

When Prepare dinner commenced the event of the HEXR helmet, 3D printing was an enormous hype, and this led him to check a wide range of supplies, layouts, and manufacturing methods based mostly on 3D printing. As soon as once more, additive manufacturing allowed HEXR, as many different nice creations, to replicate an concept, produce it, and check rapidly. As soon as Prepare dinner discovered the precise design and base materials for his helmet, HEXR was lastly able to occur.

However how is every HEXR created to suit any rider’s head? Effectively, the reply is straightforward: 3D scanning. To completely measure the top of any rider or costumer, they first must placed on a swimming cap and get their head scanned. With the assistance of an iPad and depth-sensing cameras, the measurements are obtained. 30,000 knowledge factors are collected and used to later reconstruct a digital mannequin of the rider’s head. It’s then used to create a custom-made CAD blueprint for the HEXR helmet.

HEXR’s benefits are that the helmet is lighter, extra aerodynamic (in line with eager cyclists), however most significantly they’re much less wasteful, are constituted of eco-friendly supplies and it’s a lot safer than typical helmets. Nevertheless, the value isn’t low-cost. HEXR is promoting for $390, however in case you examine it with different helmets available in the market, it nonetheless is usually a significantly better choice in case you contemplate your security.

As talked about above, HEXR just isn’t the primary helmet to be 3D printed. A Canadian agency referred to as Kupol additionally believes bike helmets might be custom-made and safer through the use of 3D printing. Gabriel Boutin, the CEO of Kupol, makes use of PA12, a plastic powder to create his helmets. In keeping with Boutin, this materials is nice for its mechanical properties. Its density and thickness. 3D printing helps Kupol create helmets obtainable in lots of sizes in comparison with the normal ones.

Currently, the biking trade is taking plenty of discover and firms are making the most of the manufacturing course of 3D printing presents. Identical to bike helmets, saddles play an vital function when using a motorcycle. As these are sometimes blamed for being uncomfortable,  Specialised partnered up with Carbon Digital Gentle Synthesis (DLS) and introduced the S-Works Mirror. Making an allowance for that to get the precise saddle there are plenty of elements to contemplate, this saddle abandons typical foam padding and is 3D printed with a lattice construction that’s connected to a traditional carbon composite base. Density and construction might be custom-made to supply actually body-specific consolation and help.
