Jet Dragster Racing [Video] with 3D Printed Parts

Not many machines can reach 280mph in five and a half seconds – but for Larsen Motorsports, this is the norm.

These jet powered drag racing cars are marvels of precision engineering, and can reach incredible speeds in a quarter of a mile. Part of what allows them to achieve these feats is the manufacturing technologies they employ – including industrial 3D printing achieved with Markforged 3D printers.

In this 6-minute video, the Larsen Motorsports team including driver Josette Roach, who has been racing since she was 16 years old, show off their machines and how they push the limits of engineering with 3D printers.

Quality, Precision and Safety

“Quality, precision, and safety are probably the biggest factors for us. Especially when it comes to the racing, because someone’s life is on the line.”Brian Tocci, Head of Operations, Larsen Motorsports

With every innovation, the Larsen Motorsports team are striving to make their parts stronger, faster, lighter, and more customized. In the case of the steering wheel and it’s specialised inbuilt controls, fitting the hands of drivers is essential for ease of use and reliability. With a Markforged 3D printer, the team were able to custom design and print a wheel for Josette Roach’s hands. Not only could they prototype and iterate on this design more quickly than traditional methods, it was much cheaper and ultimately stronger than typical machined aluminium. 

Because the design was purpose made and came off the printer as one solid part, minimal to no post machining was required for the part. In addition, new designs can be available the next day, instead of having to wait 8 days for manufacture and delivery. 

Pictured to the right are the 3D printed part for the jet dragster and it’s aluminium predecessor, and Josette Roach.

How could you use this flexibility and strength in your organisation?
