Each few months, information breaks of one other high-profile rider throwing their leg over a 3D-printed bike. Alex Dowsett, Filippo Ganna, world scratch race champion Will Tidball. The record is not precisely infinite, however every one makes headlines and will increase the sense of thriller. A shroud appears to cowl 3D printing, and as producers disclose scant particulars, pleasure builds round a darkish and thrilling artwork coming quickly to a storage or shed close to you.
In fact, it is not darkish, however it could possibly definitely be thrilling, and the probabilities it presents all of us are nearer at hand than you may think. In case your instinctive response once you first came upon that somebody printed a motorcycle was alongside the traces of “How the–?”, then you definately’ve come to the suitable place.
A really transient description of the way it works: the printer takes the fabric you feed it – whether or not that is a plastic filament or (for those who’re very wealthy) powdered titanium, or another materials – and melts it onto a baseplate, constructing it up in very wonderful element, layer by layer, till the piece is full. This is not like your normal house laser printer chucking out a facet of A4 in beneath 10 seconds, although. Until you are 3D printing one thing very small, it is an hours-long course of.
Sitting someplace among the many high branches of biking’s 3D printing tree is Tom Sturdy. He runs Sturdy Cycles in Frome, Somerset, the place creates bikes in titanium, using the liberal use of 3D printing for the whole lot from chainsets to cockpits, brake levers and even rear triangles. “I began constructing frames correctly about 10 years in the past,” Sturdy stated. “I used to be doing metal – conventionally manufactured metal frames, metal tubes both brazed or welded collectively.”

A couple of years in the past, he switched to creating bikes in titanium, utilizing 3D printing mixed with CNC machining in his personal workshop, enabling him to turn into extra environment friendly and work with a fabric for which clients anticipate to pay a premium worth. Importantly, it additionally enabled Sturdy to keep up the individuality of the bikes he was promoting.
Whereas Sturdy has his personal CNC machine in his Somerset workshop, the 3D-printed components aren’t so domestically made, no less than in the meanwhile. He sends his designs to a provider in New Zealand, which ships them over. That stated, he has used UK suppliers too. “We do the whole lot in-house right here excluding the metallic printing, and that’s due to [the cost],” says Sturdy. “You are speaking hundreds of thousands to purchase a kind of printers after which maintaining it operating will not be a small process both. Swiftly it turns into a really totally different enterprise.”
If 3D printing in biking was restricted to titanium and different costly metals such because the scalmalloy purportedly utilized in Ganna’s, Dowsett’s and Tidball’s bikes, it could be way more area of interest than it’s. Nonetheless, you may log on and purchase, for lower than £200, a funds 3D printer that may print in numerous types of plastic together with biodegradeable PLA, derived from cornstarch. Spend northwards in direction of £1,000 and you have a bit of equipment that may prove pro-level outcomes. The printing plastics are eminently reasonably priced – beginning at round £20 a kilo – and it stands to cause you can knock up fairly just a few 25g bottle cages or cable clamps earlier than operating low on a block like that.
Aerodynamics firm Aerocoach, which works with top-level groups and riders, makes use of 3D printing extensively, as director Dr Xavier Disley explains. “It is an integral a part of what we do, for certain,” he says. “We have now merchandise which might be 3D-printed; we’ve got merchandise which might be half 3D-printed, we have got 3D printers of assorted sorts.” The corporate additionally makes use of 3D printing for prototyping, the place the low value makes it supreme for producing one-off objects and making small alterations.

“[We use] the PLA stuff for very tough prototyping, getting a really feel for one thing,” says Disley. “We’re making a product in the mean time which you can slot in your fingers, and it is simply good to get hands-on with one thing. As a result of you may take a look at all of the CAD fashions that you really want on the pc, however you by no means actually know.” Disley additionally prints with resin, which might obtain the next decision (accuracy) for prototypes the place seeing how issues match to the closest fraction of a millimetre is required.
In the case of the tip product, 3D printing can be utilized to create customised items with out the necessity for a number of costly carbon moulds. “Carbon moulding is actually costly,” Disley says. “The tooling prices are nuts. So you need to be actually cautious about the way you incorporate that into your pricing plan, as a result of you are going to must move it on to the patron sooner or later.” Disley provides the instance of time trial bar extension end-grippers: “The gripper is made out of [3D printed] nylon, so it means we are able to change the form of it fairly shortly… We are able to have a great deal of totally different skews. Then we bond that nylon piece right into a carbon shaft or a titanium 3D-printed shaft if we need to make it a bit bit lighter,” he explains.
In the case of items of tube reminiscent of these bar extensions, 3D-printed titanium trumps carbon in that it permits manipulation of the interior partitions. A lattice will be launched, for instance, and it is considerably simpler to create totally different wall thicknesses.
Making a motorcycle body utilizing the method is much more durable – therefore the £55,000 price ticket on the retail model of Tidball’s machine.
Printing for the peloton
Not surprisingly, Disley’s equipment will not be the one 3D-printed goodness to search out its method into the professional peloton. Sam Rees is a mechanic with German Continental crew Maloja Pushbikers. He ended up shopping for a 3D printer with a view to furnishing the crew’s bikes with numerous trinkets. “I used to be printing quantity brackets for the riders, and simply carried on,” says Rees, who prints in a plastic known as PETG. “I do not do something structural; it is a lot better to simply do plastic after which you do not have to fret that one thing may fail. So it is usually issues like quantity holders, backside bracket spacers, little issues.”
One among Rees’s most up-to-date prints is a checking instrument for the UCI’s new brake lever angle laws. Issued as a template by the UCI itself, the instrument permits Rees to make sure his crew bikes will not fall foul of UCI sorts with clipboards. That is among the stunning issues in regards to the 3D printing world. You do not have to be a design whizz to provide you with a viable design for the merchandise you need to create. There are literally thousands of templates for nearly something you may consider (and rather a lot you most likely could not) accessible to obtain on open-source websites, and most of them are free.
The angle-checker will not be the one instrument Rees has made. His repertoire additionally features a Shimano crank remover and bearing punches. “I’ve at all times obtained the suitable instrument,” he says. “I can design it myself or by wanting on-line – very often another person has already executed it earlier than, so I contact them and ask them for the file.” The 3D-printing group is pleasant in that method, Rees says, with most keen to assist one another out. He prints objects for different crew mechanics who do not have 3D printers.
Proudly owning an organization or working for a UCI crew is not a prerequisite for entry to the 3D-printing membership. Glasgow-based Ryan Fearne heads up part firm Experience Stash Parts, however for him 3D printing started as a interest. Having labored in quite a few bike retailers, Fearne graduated in sports activities engineering after which labored in medical gadgets, the place he was surrounded, as he places it, “by plenty of toys and 3D printers, high-end kind of stuff”. He subsequently purchased his personal desktop mannequin to print all method of fine details, from home items to cycling-related items.

Fearne got here up together with his Experience Stash mount after struggling a mechanical whereas out driving and realising he wanted an honest instrument mount. Unable to search out what he wanted on-line, he set about designing his personal, and the Experience Stash mount was born. Realising he had created an efficient product, he determined “we’ll market it” – and it’s proving widespread. Fearne prints on UV-resistant ASA plastic in an enclosed printer with filters to stop dangerous fumes. Within the early phases, Fearne handed out the mounts to associates, appearing on their suggestions.
Whereas it appears to have rather a lot going for it, 3D printing is thought to be doubtful by some shoppers, in accordance with Fearne. “It is not good for the whole lot,” he concedes. “I suppose with me it is attempting to indicate that, , you will get some actually good high quality components out of it.”
How lengthy, then, earlier than we’re all driving off into the sundown on our 3D-printed bikes? Whereas it is clearly doable to print a motorcycle, that bank-account-busting swing tag on Tidball’s bike strongly suggests that is not the imminent future for many of us. Sturdy units out the prices of what he does versus the large identify bike manufacturers constructing in conventional methods.”For these firms, the price of the supplies is just a few hundred {dollars}. My materials value is round 50% of what I am promoting the bike for. For me, you are speaking 10 to 12 occasions what it could value different firms to supply their bikes,” he explains. “It could take lots of effort for that method to work for the business on an even bigger scale.”
It is extra possible that, as 3D printing slowly breaks into the mainstream, with printers and supplies turning into extra refined and reasonably priced, 3D printing goes to turn into the go-to choice for the typical rider trying to create a helpful mod for his or her machine or workshop. “It is positively getting in direction of the mainstream,” says Fearne. “Most individuals will know somebody who’s a bit bizarre and 3D-prints stuff,” he jokes, “and it is nice to see a great deal of individuals choosing it up and utilizing it for biking. If individuals have a selected downside, they need not go and hunt for the suitable half, they will have a crack at designing themselves.”
As a mechanic, Rees predicts the 3D printer can have an more and more useful position as a workshop sidekick, not only for crew workers like himself however in retailers too. He provides the instance of a earlier bike store he labored for with the ability to substitute a buyer’s out of date fork bushing.
You are unlikely to search out your self on a 3D-printed bike any time quickly. However the possibilities of your bike ending up with one thing 3D-printed bolted to it – or maybe having been adjusted utilizing a 3D printed instrument – are more and more excessive. That bolt-on may even be one thing you printed your self.
CW tried it: ‘Look ye, a printed drip catcher!’
Biking Weekly net editor Michelle Arthurs-Brennan on her personal 3D-printing experiences
Our family’s Creality 3D printer is, in my husband’s phrases, “the equipment automotive of 3D printers”. It’s fiddly, comes with its personal idiosyncrasies, however makes for an pleasing interest. It set us again simply £120.
Regardless of each being cyclists, we’ve but to print something bike-related. The closest we’ve obtained to a 3D-printed biking product has been an ‘Aeropress drip catcher’ – how did we cope with out it?! To this point, the designs we’ve used have come from open supply web sites, such because the aptly named ‘Thingiverse.com’. Highlights embrace the cable organiser we by no means knew we would have liked, and the right toothbrush holder.
To print bike components, we must improve to dearer, extra resilient printing materials reminiscent of ABS – the draw back of which is a poisonous particulate danger. We might possible want a dearer printer too, reminiscent of a Bambu, whose printers include filters to lure poisonous particles.
Filippo Ganna’s 3D printed Hour file bike

On the high degree, 3D-printed bikes have been utilized by Filippo Ganna, Alex Dowsett and Will Tidball, creating fairly the excitement across the manufacturing methodology
Pinarello, which developed Ganna’s Bolide with UK-based Metron AE, was very open about its machine. Created in 5 bonded components produced from a scandium-aluminium-magnesium alloy known as scalmalloy, it options shapes unattainable to make utilizing carbon-fibre. Ganna used the bike to nice impact, knocking the Hour file out of the park together with his 55.792km in October 2022.
Dowsett’s crew employed 3D printing to create a track-going rear triangle in titanium for his favoured Issue Hanzo time trial bike. He additionally used Aerocoach 3D-printed handlebar extensions for his 2021 try at reclaiming the Hour file, which in the end fell round 500m wanting the mark.
In distinction, Tidball’s bike, developed by the UK Sports activities Institute (UKSI), is shrouded in secrecy, little question partly as a result of it’s for use at this 12 months’s Paris Olympics. Bearing the catchy moniker UKSI-BC-1, the one info on the UKSI web site is that the bike is being “constructed utilizing 3D printing”.
Not all of 3D printing’s cycling-related headlines are constructive. The Australian crew pursuiters fell foul of a snapped 3D-printed base bar throughout the qualifying rounds on the Tokyo Olympics in 2021. It was faraway from sale by producer Bastion instantly afterwards.
