F

ans of the Warhammer franchise and fantasy wargaming in general were no doubt aware that video game developer SEGA was releasing Warhammer 40,000: Dawn of War III earlier this year. But as well as this niche market, SEGA also wanted to create a buzz around the release in mainstream media too. It decided to do this by giving members of the press an opportunity to wear a reallife working replica of the Warhammer Power Fist.

In the game, the Power Fist endows the Space Marines with superhuman punching power making it easy for them to hammer there way through an armoured tank, for instance, to tear out the passengers. Although SEGA didn’t exactly have that kind of power in mind, it wanted to at least give wearers the ability to punch through a brick wall or a hefty object such as a toilet.

“We also got some rough dimensions and basically it was a process of copying what they had created into SolidWorks and then working out how the whole thing was going to fit together.”

The client wanted a rapid turnaround and within a week and a half of receiving the internal components Luma-iD was able to send the completed files to the manufacturers.

The main fist component was sent to 3D Systems Europe, which created the 3D print as a single piece in glass reinforced nylon. Meanwhile the fingers were sent to Proto Labs where they were CNC machined from solid aluminium. “The lead time for the 3D printing and the metal machining was another three to five days, which is still pretty fast,” says Passmore.
