A 3D printed security gadget has helped save the lifetime of an NTT INDYCAR SERIES driver.
Josef Newgarden was concerned in a high-speed collision with Louis Foster in the course of the latest Bommarito Automotive Group 500 race on the World Huge Know-how Raceway in Madison Illinois.
Newgarden, a two-time INDYCAR SERIES champion, collided with Foster on lap 131, sending his No. 2 Chevrolet airborne. The Staff Penske driver landed the other way up, earlier than skidding alongside the tarmac in a bathe of sparks.
After being righted by the American Medical Response Security Staff (AMR), Newgarden was capable of climb out of the car, escaping severe harm. The brunt of the pressure was absorbed by his Aeroscreen, a 3D printed cockpit security gadget that was first launched in 2020 and up to date with a extra light-weight design in 2024.
Foster, a Rookie driving for Rahal Letterman Lanigan Racing, spun out with main injury to his Honda-powered Dallara chassis. He additionally walked away largely unscathed after his Aeroscreen deflected a hail of particles.
The gadget is a compulsory characteristic on all NTT INDYCAR SERIES automobiles for street and road course races. It incorporates a 3D printed titanium body, engineered by Crimson Bull Superior Applied sciences (RBAT) and manufactured by the Austrian mechanical methods firm Pankl.
This body is paired with a laminated polycarbonate ballistic windscreen, developed by plane windshield specialist PPG Industries. Collectively, they kind a protecting barrier comparable in operate to the Halo crash-protection system utilized in Components 1 since 2018.
3D printed Aeroscreen enhances IndyCar security
Previous to its 2020 debut, a number of manufacturing methods had been explored for Aeroscreen manufacturing.
The primary design was reportedly made utilizing titanium casting. Nevertheless, prolonged manufacturing lead instances made it unable to satisfy the tight deadline forward of the 2020 INDYCAR season opener. Consequently, Pankl was chosen to manufacture the body utilizing its EOS M400-4 laser powder mattress fusion (LPBF) 3D printer.
The unique Aeroscreen (Model 1.0) featured a body constructed from 5 3D printed sections welded collectively. In pre-race testing, it withstood forces equal to 34,000 kilos, whereas the ballistic windscreen was examined to endure the impression of a 17.3-pound object touring at 220 mph. The gadget made its on-track debut throughout testing at Indianapolis Motor Speedway in October 2019 and was formally launched in competitors in February 2020.
Final 12 months, INDYCAR launched Model 2.0, a lighter display screen designed to reinforce efficiency and luxury. It contains built-in air vents to enhance cockpit cooling, together with a front-facing rubber 3D printed to assist forestall hand accidents throughout a crash.
The up to date design first hit the observe in the course of the 2024 Acura Grand Prix in Lengthy Seashore. Its weight was trimmed from 18.9 lbs on Model 1.0 to 14.5 kilos, whereas retaining the identical energy as the unique. That is due to the brand new, topologically optimized 3D printed titanium body.
Mixed with the ballistic windscreen, the up to date Aeroscreen affords a complete weight discount of 11.1 kilos, decreasing downforce by roughly 35 lbs.
Enhanced cooling performs a vital function in boosting driver efficiency, in line with Tino Belli, Director of Aerodynamic Growth for the NTT INDYCAR SERIES. She famous in a press launch that drivers constantly emphasised the necessity for higher airflow, as their physique temperatures typically exceed 100°F throughout races. Racing groups may set up an non-compulsory filter to assist hold mud out of the cockpit.
Additive manufacturing accelerates motorsport
3D printing shouldn’t be new in motorsport. Racing groups have lengthy leveraged additive manufacturing to supply an edge on the observe. For instance, the Oracle Crimson Bull Racing F1 Staff is a eager adopter of superior applied sciences, together with 3D printing.
In an interview with 3D Printing Trade, Ian Handscombe, Head of High quality Engineering at Crimson Bull Racing, claimed: “I don’t suppose we’ll proceed to be on observe except we embrace [3D printing].”
Technical partnerships with firms play a key function in supporting additive manufacturing at Crimson Bull Racing. A lot so, forward of the 2025 F1 season, Crimson Bull prolonged its long-term collaboration with manufacturing know-how firm Hexagon. This builds on an 18-year-long relationship with Hexago because the staff’s unique metrology accomplice.
The Swedish agency provides Crimson Bull with 3D scanners and digitalization capabilities. This know-how permits the F1 stalwart to make over 20,000 automotive design modifications every season. In keeping with Hexagon, metrology know-how has helped minimize faults by over 50% over the previous two years.
Elsewhere, BWT Alpine F1 staff leverages 3D Techniques’ SLA and SLS 3D printers to assist Components 1 wind tunnel testing. The racing staff reportedly 3D prints 25,000 components yearly to cut back analysis and growth time and enhance on-track efficiency.
Equally, the McLaren F1 racing staff has a protracted partnership with 3D printer OEM Stratasys. Relationship again to 2017, this collaboration has seen McLaren leverage 5 Stratasys Neo 800 to assist aerodynamic wind tunnel components. Elsewhere on the grid, Alfa Romeo Racing made intensive use of Additive Industries’ MetalFAB1 3D printer in the course of the 2021 season. The staff 3D printed light-weight racing automotive elements, which price 90% lower than these produced utilizing conventional strategies.
