Back in 2012, Bogue, Cowen and Dilworth were having a hard time with a 3D print. Somewhere along the hours-long process they endured to make a toy prototype, the printer they were using missed a few layers. They lamented about how much easier the whole process would be if they could just take the nozzle off the printer and fill in the gaps. This was their eureka moment.
They knew what they were making was something unique. “It’s a massive game-changer,” explains Cowen. “You could never just pick up a pen and create an object in 3D before. Now you can.” The ability to draw in thin air was definitely something new, so creating a machine small enough to fit in your hand to allow users to draw with ease was going to be a challenge.
