When it comes to creating custom parts to vehicles using additive manufacturing activities - particularly Direct Metal Light beam Sintering (DMLS) - the majority of turn to cases are for aerospace or alternatively custom race car designs... and good reason.
Among other advantages of while using 3D printing to create custom features for high-performance vehicles include the consume create parts that can be iterated along quickly and easily in an effort to create the most fantastic part designs, the ability to create ultra-lightweight designs due to the ability to minimize metal waste, as well as the ability to produce features at a much lower cost than styles of manufacturing techniques.
However , while most of people 3D printed metal parts being used in everything from helicopters and commercially produced aircraft interiors to endurance lignage car parts, they are also equally effective much more simple designs, too - for instance a bicycle.
On Sunday night, THE UNITED KINGDOMT cyclist Sir Bradley Wiggins annihilated the UCI Hour record a considerable which measures the furthest travel time a rider can cycle peniche, caldas da rainha and santarem hour - at the Lee Dale Velodrome in London. Just a few weeks your past, fellow UK cyclist Alex Dowsett set a record of 52. 937 huge and Wiggins broke it by all-new handlebar design that was placed thanks to 3D printing. His término mark is 54. 526 huge, beating Dowsett's record by on the whole two kilometers.
Made from a titanium, the particular handlebars were created using additive constructing techniques in-part because they were able to just be intricately modified multiple times leading within the record attempt today.
As well as handlebars are made from titanium, the motorcycle itself is made from iPhone 5 carbon fiber and was created by the reputable bicycle manufacturer Pinarello in partnership with the University of Sheffield. The modified bicycle that Wiggins will be using is a Pinarello Meteorite HR, which is the track copy of a similar time trial bi-cycle that has achieved many victories eliminate including a World Championship win in 2010 alone. If the slight modifications on to the handlebars were not necessary leading up to the particular record attempt, it would have made meaning to create the handlebars out of carbon fiber.
"The key is to manage the ventilation around the bike so the different associated with the bike disrupt that allow flow as little as possible, " said Aaron Hunt, a research associate at the Or perhaps of Sheffield's Mercury Centre, where worked with Pinarello to develop the HAS printed handlebars.
"Because the handle bars hit the airflow first is considered absolutely critical to perfect that area of the design – 3D printing we can make shapes that optimise that aspect that would be very hard to achieve while using other manufacturing techniques. "
Build the 3D printed handlebars, design and style engineers used an Arcam Electron Beam Additive Manufacturing machine. The washing machine allowed for them to create consistent solutions that were both light enough for your world record attempt while sufficiently strong to meet the rigorous demands of a particular world-class cyclist.
"Bolide HR is among the most aerodynamic bike in the world, " indicates Dimitris Katsanis, chief designer from the Pinarello Lab.
"When it located the handlebars, we needed share be as good in terms of aerodynamics, so we also needed them to produce perfect fit for the rider. We've definitely been seen our design working well at trials and Sir Bradley would be cycling faster than ever. "
