Here we’ve what’s undoubtedly one of the crucial superior titanium tubing bicycle frames ever created -. Yet you’ve in all probability by no means seen or 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 brand new route for the individuals behind Mirada Pro.

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

Taken from design to manufacture in just eight weeks, the body uses a number of 3D-printed titanium lugs which are welded to customized titanium wire tubing from Reynolds.

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

The design additionally allows for welds to be moved away from high stress areas, and for the surfaces destined for welding to be simplified. Less parts and lowered machining occasions mean that manufacturability needs to be improved whereas costly tooling will also be accomplished away with.

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

The metallic part to the left was historically CNC milled from a big titanium billet. On the appropriate is the redesigned model of the identical element, and one that’s optimised for 3D printing. Compared with the original design, the 3D-printed half provides the same energy and stiffness however is 50% lighter. Better but, the economic system of the method is on another degree: the CNC process producing a outstanding 70% of waste material compared to just 2% from the 3D printed half.

Indeed, it wouldn’t be going too far to say that 3D printing is enjoying its personal industrial revolution, however to say this know-how will do away with more conventional manufacturing could be unsuitable, not less than for the foreseeable future.

Restrictions with 3D printing at present revolve around the cost of the printers themselves, that and the physical measurement restrictions of the beds within them. Similarly, though tolerances from 3D printing are already very spectacular, sometimes they aren’t quite shut sufficient for essentially the most demanding applications, and so many 3D-printed parts shall be finished via CNC. The process isn’t only a case of clicking print either, and every half will require work to assist with powder removing, heat remedy and finishing.

A unique design method

New methods of manufacture also require a new take on the design process, and this is where 3D printing actually does get interesting. Suddenly, longstanding design guidelines have gone out of the window as shapes and constructions that would’ve previously been uneconomical or even not possible are actually easily achievable.

Rather than painstakingly removing materials in the right places, software is ready to pinpoint exactly where stress happens, and demonstrates to designers where and how much materials must 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 checks, which engineers then enter into their CAD program. This system then interpreted how a lot titanium powder wanted to be where in a formation that would offer the correct energy however with minimal materials. Just take a look on the CAD drawing below. You’ll notice giant vein-like structures that cross via the design. These constructions have largely been depicted by the software program used to design the body, and you can see straight how they translate to the completed elements.

Why Ti?

Cost restrictions implies that standard titanium frames are comparatively uncommon in the cycling world though 3D printing does add an attention-grabbing spin on things. Titanium actually works out to be the most cost effective materials that Mirada Pro works with, though the machines are capable of producing an identical components from alloy or stainless steel, both can be significantly more time consuming in the printer, remember – time = money. Actually, printing with aluminium takes twice as lengthy because it does with titanium.

What goes between the lugs is one other matter altogether, and what’s at the moment full of Reynolds titanium wire tubing could simply as simply be carbon fibre. This brings one other benefit to this design, its versatility. Tweaks on the design stage may make it doable for this frame to be completely modular: need completely different tube stiffness for various sized frames? straightforward. Geometry or sizing adjustments could easily. Quickly be made in a means that isn’t actually attainable as issues stand. A web based configurator may very well be made to print out a bike to your exact spec.

Who’s behind Mirada Pro?

Mirada Pro is an arm of Birmingham-based 3D printing specialist Innovate 2 Make (i2M). The majority of its work stems from the aerospace and motorsport industries, where the benefits of 3D printing manufacturing are already properly established. This gives Mirada Pro a big benefit as, not like most people in possession of a 3D printer, its crew have machines that run nearly always.

In manufacturing, time = cash, and the extra these machines are lively, the extra cheaply such parts may be produced in volume. As such, Mirada Pro insists that it could create frames and components that may prove price efficient in today’s market, and that’s just what it intends to do.

Mirada Pro is for now merely dipping its toes into the bicycle enviornment, however has strong intentions to supply a frame sometime within the near future.

Interestingly, the agency is aiming to work with framebuilders slightly than larger manufacturers to fulfil its short-time period ambitions. It’s a reputation you should certainly look out for in the future.
