Sam's jet pack is able to climb to an altitude of 3,048 km and reach speeds of 80km/h. The five-turbojet engine race suit was printed entirely in aluminium, steel and nylon and cost £340,000 to develop. It was developed as part of his degree and produced by Gravity Industries.

The company has tested it before, at up to 51,5 km/h, but Sam decided to prove that the device can show more results.

"Five turbojet engines spooling up on your body is a very intense and visceral experience,' the Product Design and Tech student said. 'To learn to balance, control and fly under that power feels very dynamic and the freedom of movement once airborne is like nothing else."

The suit consists of kerosene-fueled turbines worn on the back and each of the arms. Each one generates 22kg of thrust and Sam can pilot it using controls on the inside of the hand grip.

"Multiple versions of the suit were tested with leg engines and various other engines configurations,' Sam said. 'And I found that turbines on the arms and back was the optimal configuration. I redesigned the suit from traditional materials to being entirely 3D printed in aluminium, steel and nylon, which reduced the time and cost of building the suit."

According to Sam, he is planning to make a faster, more powerful and lightweight suit. He would also like to add wings so he could lie horizontally while flying.

Dr. Andrew Johnson, a lecturer in product design, said: "This project is a great way to highlight that additive manufacturing is playing an ever-increasing role in the design and manufacture of prototype and end-use products."
