From dot matrix to the starting grid: Racing car created by 3D printer can go from 0 to 60mph in just four seconds

  • Giant 3D printer created the the race car - engineers just added engine and wheels to get the vehicle moving
  • Design took just three weeks to go from concept to reality
  • Successful test runs carried out at Hockenheim and Silverstone race tracks

Over the last few years, 3D printing has started to come off the starting grid.
The technology, akin to paper-printing, sees nano-layers of plastic built up layer-by-layer to create a solid 3D object of practically any design.
Now the technology has undergone one of its largest test yet - printing out a full-sized race-car, which has now successfully competed on the Hockenheim race circuit in Germany.
A 16-man strong team of 'next-generation engineers' from Belgium designed the car, which can go from 0 to 60mph in just four seconds, and can reach 141km/h (87mph).

The team of engineers, from the Group T-International University College took three weeks to take the car, named 'Areion' after the extremely swift, immortal horse of Greek mythology, from concept to reality.
They went to 3D printing firm Materialise, which has an appropriately-named 'Mammoth' 3D printer, which can manufacture parts of up to 210x68x80cm.
This allowed them to take the team's designs for the shell of the vehicle, and import the digital files into the Mammoth, before the team sat down to watch the machine print out the vehicle in front of their eyes.

Starting from the group's design for the outer shell, engineers at Materialise applied their experience from other projects to the creation of the car body, which included integrated clips and connection points, making it easy to 'slot' the car together.
The intricate printing process saw much of the car's inner-structure built in to the design, making the shell of the vehicle practically complete once printed, needing little more than wheels and an engine to start moving.
Both the right and left sides of the car were designed and printed with complex cooling channels.
Printed into the left side pod are a nozzle behind the radiator and a diffuser, which optimise cooling by creating the ideal flow of air through the radiator.
A fan was also installed behind the radiator in order to help airflow even at low speeds and while the car is stationary.
In the right side pod, complex channels were developed and printed to create a cyclone effect that removes water and dirt from the air before it enters the engine compartment.

Once the engine was added, the 3D car was ready for its test run, which was completed on the race track earlier this month. It has now also completed a circuit at Silverstone in the UK.
A spokesman for Materialise said: 'With a build envelope that massive, the Formula Group T team recognised the possibility to not only print the entire body of the car, but to also integrate some unique features directly into the design.
'Cutting-edge technologies incorporated into their eco-friendly race car included an electric drive train, bio-composite materials, and of course, 3D printing on a grand scale with Materialise.  
'Therefore, working in close collaboration with engineers at Materialise, this is exactly what they achieved: going from initial shell design to a fully finished 3D Printed car body in just three weeks.'
3D printing its still in its infancy, although commercial and even domestic printers are now hitting the market.
The technology opens up the exciting world of 3D printing to both industry and the public, with many applications in science and medicine.
For instance, in the future, you may be able to print out small items for your life - almost anything from cups to trainers.
The medical applications are also significant.
The technology has been trialled in dental work and bone reconstruction, with one lady having her jaw reconstructed via 3D printing following a bone infection.
