Here we’ve got what’s undoubtedly one of the crucial advanced bicycle frames ever created -. Yet you’ve in all probability never seen and even heard about it.

Produced as a joint collaboration between UK agency Mirada Pro, tubing specialist Reynolds and framebuilder Ted James Cycles, the body is at the moment a one off that demonstrates a new direction for the people behind Mirada Pro.

Robot Bike Co R160: the way forward for bike design?

Taken from design to manufacture in just eight weeks, the frame uses multiple 3D-printed titanium lugs that are welded to customized titanium tubing from Reynolds.

Look nearer and you’ll see 3D printed titanium lugs make up the pinnacle tube, backside bracket, titanium bar dropouts and high tube/seat tube intersection. These lugs have been welded to custom drawn titanium tubes from Reynolds in a 53cm frame that emulates the geometry of a standard alloy road bike. The result’s a sub-1kg (999g) frame that Mirada Pro claims offers improved torsional stiffness over a comparable alloy merchandise.

The design also allows for welds to be moved away from excessive stress areas, and for the surfaces destined for welding to be simplified. Less elements and reduced machining occasions mean that manufacturability needs to be improved whereas expensive tooling will also be performed away with.

The potential of 3D printing in bicycles is but to be absolutely realised but under is an honest example of how the expertise has made a giant affect among different industries – this one’s from the world of aerospace.

The metal component to the left was traditionally CNC milled from a large titanium billet. On the precise is the redesigned version of the identical part, and one that’s optimised for 3D printing. Compared with the unique design, the 3D-printed half affords the same power and stiffness but is 50% lighter. Better but, the economic system of the method is on one other degree: the CNC course of producing a remarkable 70% of waste material in contrast to only 2% from the 3D printed half.

Indeed, it wouldn’t be going too far to say that 3D printing is having fun with its own industrial revolution, but to say this know-how will get rid of extra traditional manufacturing could be improper, at the very least for the foreseeable future.

Restrictions with 3D printing at the moment revolve round the price of the printers themselves, that and the bodily measurement restrictions of the beds within them. Similarly, though tolerances from 3D printing are already very spectacular, typically they aren’t fairly close enough for the most demanding applications, and so many 3D-printed parts can be finished by way of CNC. The process isn’t just a case of clicking print either, and every part will require work to assist with powder removing, heat treatment and finishing.

A distinct design method

New strategies of manufacture also require a brand new take on the design course of, and this is the place 3D printing actually does get attention-grabbing. Suddenly, longstanding design rules have gone out of the window as shapes and constructions that would’ve previously been uneconomical or even unimaginable are actually simply achievable.

Rather than painstakingly eradicating materials in the proper places, software program is able to pinpoint precisely where stress happens, and demonstrates to designers where and the way a lot materials should be present.

Within the case of this frame, Mirada Pro used the load figures a body needs to attain with the intention to move EN security assessments, which engineers then enter into their CAD program. The program then interpreted how a lot titanium powder needed to be where in a formation that would offer the correct energy but with minimal material. Just take a glance on the CAD drawing beneath. You’ll discover large vein-like structures that move by the design. These constructions have largely been depicted by the software used to design the frame, and you’ll see immediately how they translate to the completed elements.

Why Ti?

Cost restrictions implies that standard titanium frames are comparatively uncommon in the cycling world although 3D printing does add an fascinating spin on issues. Titanium really works out to be the most affordable material that Mirada Pro works with, regardless that the machines are capable of producing identical components from alloy or stainless steel, each could be significantly more time consuming within the printer, remember – time = cash. The truth is, printing with aluminium takes twice as long as it does with titanium.

What goes between the lugs is another matter altogether, and what’s at the moment full of Reynolds titanium tubing may simply as simply be carbon fibre. This brings another advantage to this design, its versatility. Tweaks on the design stage might make it potential for this frame to be completely modular: want completely different tube stiffness for various sized frames? easy. Geometry or sizing adjustments might easily. Quickly be made in a way that isn’t actually doable as issues stand. An online configurator could be made to print out a bike to your actual spec.

Who’s behind Mirada Pro?

Mirada Pro is an arm of Birmingham-based 3D printing specialist Innovate 2 Make (i2M). If you loved this short article and you would like to receive much more facts concerning titanium rod (pastelink.net) kindly check out our web site. The majority of its work stems from the aerospace and motorsport industries, where the benefits of 3D printing manufacturing are already properly established. This offers Mirada Pro an enormous benefit as, not like most people in possession of a 3D printer, its workforce have machines that run nearly continually.

In manufacturing, titanium sheet time = money, and the extra these machines are lively, the more cheaply such parts might be produced in quantity. As such, Mirada Pro insists that it may create frames and elements that would show price efficient in today’s market, and that’s simply what it intends to do.

Mirada Pro is for now merely dipping its toes into the bicycle enviornment, but has sturdy intentions to supply a frame sometime within the near future. Interestingly, the agency is aiming to work with framebuilders fairly than larger manufacturers to fulfil its brief-term ambitions. It’s a name you must actually look out for sooner or later.
