3D sketching pens are big news this year, but the high temperatures required to melt the plastic could make parents wary about letting the kids play with them.
Now, however, a new pen has been unveiled, which uses ABS/PLA plastic with photo-polymers that solidify under a blue light emitted from the pen's tip.
The Polyes Q1 uses a light-curing process which means the pen doesn't have a hot nozzle or smell.
The brainchild of Delaware, US-based studio Future Make 3D, the cordless pen is aiming to become the first child-safe 3D sketching pen on the market and is expected to launch a Kickstarter campaign soon following its debut at EXPO in China.
3D pens have been a runaway success this year, with inventions such as CreoPop — billed as "the world's first cold ink 3D pen" — garnering attention for its technique, which uses light-sensitive ink solidified via UV light.
The miniature Lix pen, which at just 16.5cm long has been marketed as the smallest 3D pen on the market, has also proved hugely popular. — AFP/Relaxnews 2014
