Speedy process creates objects using oxygen, UV light and liquid resin
Researchers have created a versatile method for producing three-dimensional objects from a puddle of goo in mere minutes — faster than current 3-D printers by orders of magnitude.
The technique, reported online March 16 in Science, manipulates a liquid resin, ultraviolet light and oxygen to create objects with precision down to less than a tenth of a millimeter. It could be used to manufacture products such as engine parts and medical devices.
“They really thought about the chemical process,” says chemist Lee Cronin of the University of Glasgow in Scotland, who was not involved with the study. The speed and chemical tricks will “definitely move the field forward,” he says.
Scientists have been using 3-D printers since the 1980s to manufacture custom pieces, layer by layer (
