Method 1 is the very best class of auto racing sanctioned by the Fédération Internationale de l’Car (FIA), that means F1 automobiles are the quickest road-course race automobiles on this planet, able to reaching 370 kmh (230 mph) and pulling over 6 Gs round corners. They’re so quick that the drivers are required to have Tremendous Licenses, the very best class of racing license issued by the FIA. It takes a whole lot of engineering to make automobiles go that quick, and each F1 group makes use of cutting-edge expertise to stay aggressive, which suggests each F1 group makes use of 3D printing.
Every time one thing must be quick, it must be light-weight and aerodynamic, two issues 3D printing excels at. The explanations that engineers are adopting 3D printing for rockets and fighter jets are the identical causes that F1 groups are utilizing the expertise: weight discount and geometric freedom. Not solely do exterior components need to be form-fitting to scale back drag, however F1 automobiles are very small for the quantity of horsepower and expertise that’s crammed into them, so all the inside components need to take up as little room as attainable. Many elements need to nest inside each other and should be designed to suit no matter house is out there, and there’s no higher manufacturing technique than 3D Printing for fabricating such components.
After all, the automobiles aren’t the one issues flying by in F1, there’s additionally time. The rules change each season so the groups principally construct new automobiles yearly. It’s onerous sufficient to remake the identical automobile yearly, however after factoring in time for making regulatory modifications, R&D enhancements, testing, inspections, and practising, it turns into clear that the groups wouldn’t have time to sleep in the event that they didn’t depend on 3D printing. Solely AM can produce iterations of components quick sufficient to maintain up with the blistering tempo of F1.
F1 was an early adopter of 3D printing, having used the expertise to provide the size fashions utilized in wind tunnel checks because the late 1990s. And AM remains to be used for the wind tunnel fashions in the present day, but it surely’s used for a lot greater than that now.
Alfa Romeo Racing lately introduced that their 2020 season automobile sports activities 143 steel 3D printed components, most of that are several types of Titanium and Aluminum alloys printed on 4 MetalFAB1 methods. Printing all of these components resulted in a 2% weight discount, which is important in F1 the place each gram issues. Every part from cooling circuits and security constructions to chassis inserts and fairings had been printed, and even among the bodywork as properly. Alfa Romeo acquired its fourth steel printer in 2019, and so they work alongside 5 large-format SLA printers and some SLS printers from 3D Programs that permit the group to print in a variety of isotropic supplies.
There aren’t too many pictures of the 3D steel printed F1 components obtainable, however this one was discovered on the Alfa Romero F1 web site. It seems to be some form of duct cowl or vent.
3D printed metals permitted by the FIA
Elementum 3D simply bought two of its high-performance Aluminum alloys for 3D printing permitted by the FIA for the 2021 season. A6061-RAM1 and A2024-RAM2 are each extremely light-weight, but sturdy, supplies that can permit the groups to shave much more mass off of the automobiles. A number of different metals utilized in AM had been permitted as properly, together with Inconel 625, Cobalt Chrome, and extra Titanium and Metal alloys.
The 2021 checklist comprises the next part on permitted additive steel supplies:
Aluminium Alloys; AlSi10Mg, AlSi7MG, Al Cl-30AL
Aluminium Alloys with particulate reinforcing, A20X, 2024-RAM2, 6061-RAM2
Aluminium-Magnesium Alloys; Scalmalloy
Titanium Alloys; Grade 1, Grade 2, Ti6Al4V, Ti 5553, Ti 6242.
Metal Alloys; 316, 304, MS1, 15-5PH, 17-4PH, 300M, 4140.
Copper Alloys not containing Beryllium.
Superalloys; Inconel 625, Inconel 718, Cobalt-Chrome.
Regulatory wind tunnel checks
The FIA can also be utilizing AM for its regulatory testing of 2021 automobiles. The group depends on wind tunnel checks to information their regulatory choices, and due to enhancements in print high quality, it’s now attainable to make use of smaller fashions than what had been used traditionally. 100% scale fashions are banned as a result of quantity of (arguably pointless) prices related to making them, so most groups use 60% scale fashions. In a wind tunnel check, there are two main parts to think about: the forces being utilized to the automobile and the turbulence within the currents behind the automobile. Each parts can create drag and gradual the automobile down. By utilizing a smaller mannequin, there’s extra room within the wind tunnel to look at the currents behind the automobile. Nonetheless, because the mannequin will get smaller, the small print develop into much less correct, which then decreases the accuracy of the wind checks. Up till lately, a 60% mannequin provided probably the most balanced perspective, however now that 3D printers can seize extra particulars, a 50% mannequin could also be more practical.
In case you think about you have got a full dimension automobile in there, you can solely have a look at a tenth of a automobile behind it. So 50% is an effective compromise in that we are able to nonetheless get a very good stage of element on the mannequin however we nonetheless have distance behind. It’s true groups have tended to go extra to 60% lately. There are benefits to that, in modelling, however trendy manufacturing methods, significantly additive manufacturing and stuff like that means that you can make very correct 50% fashions lately.Pat Symonds, F1’s Chief Technical Officer
Turbulence within the wake
The FIA is making an attempt to craft rules that permit extra overtaking throughout races, which is why they’re so involved with the wake behind the automobiles. If there’s a whole lot of turbulence within the wake, then drivers gained’t have the ability to get shut sufficient to the automobile in entrance of them to overhaul. So the 50% fashions give a a lot better view of that wake. Their checks confirmed that the wind tunnel outcomes very carefully match the CFD (Computational Fluid Dynamics) outcomes, which is nice information because it’s a lot simpler to run a CFD simulation.
Metallic 3D printed F1 perfume bottle
And simply to place a cherry on prime, F1 debuted its first (and presumably solely) perfume in 3D printed steel bottles which might be sculptures in and of themselves. Ross Lovegrove, Welsh industrial designer, is behind the unique bottles. They’re meant to symbolize the spirit and uniqueness of F1, as Lovegrove explains in a method that sums up this text fairly properly, “These designs are solely attainable of their complexity by way of this new expertise: additive 3D printing. The factor is, between steel printing of titanium and the stainless-steel variant, they’re nearly unimaginable to repeat as a result of they’re so complicated, as is a F1 automobile, so it’s a self-protecting, self-defining type of design.”
From April 2020, these fragrances will attain retailers globally. This time Lovegrove will use Carbon’s DLS expertise, creating an intricate technopolymer exoskeleton to deal with the perfume bottle. These will probably be obtainable beginning at $250 obtainable at choose retail.
