Printing Pen Turns Doodles Into 3D Art
A 3D printing pen has been invented that lets people draw in the air - turning their doodles into three-dimensional objects.
The 3Doodler, which looks like a cross between a large pen and a soldering iron, melts coloured plastic, which then flows from the nib end of the device.
The melted plastic cools almost immediately due to an in-built fan, allowing the artist - or rather writer - to create three-dimensional pictures or structures.
US firm WobbleWorks has produced a video showing how the device works.
The pen is used to make basic objects like a coiled spring, to more complex items such as a small house with smoke coming from its chimney.
The company showed off an ostrich and dragonfly - and even a scale model of the Eiffel Tower. Different coloured plastic can be used, and the pen can be reloaded to let the user create multi-coloured designs.
WobbleWorks co-founder Peter Dilworth explained: "We wanted to design a 3D printing device that could be used within minutes, without needing any technical knowledge, software or computers.
"We also wanted it to be affordable as well as fun, so that anyone could 3Doodle!"
The existing device is powered from the mains electricity, but a cable-free version of the pen is in development.
The firm says the pen can be used by anyone who can "scribble, trace or wave a finger in the air".
As well as models, the pen can be used to create jewellery, toys, decorative art or fridge magnets.
The product was funded via Kickstarter, and the company is taking pre-orders.
