Terminator-inspired printer ‘grows' objects

A 3D printing process that harnesses light and oxygen has been demonstrated at the Ted (Technology, Entertainment and Design) conference in Vancouver, BBC News reported.

Carbon3D said its "game-changing" process could make objects such as car parts, medical devices or shoes.

The technique was inspired by the film Terminator 2, in which the T-1000 robot rises from a pool of metallic liquid.

One independent expert told the BBC the technology showed huge potential, if the company's assertions stood up.

"It's not unusual for huge claims like this to be made," said James Woodcock, group editor for TCT Magazine.

"But as it's renowned experts working on it, it gives it some gravitas."

On the Ted stage, the Carbon3D machine produced a plastic ball from a pool of resin in 10 minutes.

"It would traditionally take up to 10 hours to print this," Carbon3D chief executive Prof Joseph DeSimone told the audience.

He said that current 3D printing methods had some fundamental flaws.

"First up, the name is a misnomer. It is really 2D printing over and over again," he said.
The process is also often very slow.


"There are mushrooms that grow faster than some 3D-printed parts," he joked.


And finally the objects created by traditional 3D printing are often mechanically weak because they are made up of multiple layers.


His method is 25 to 100 times faster and can print solid final parts. It can, he said, potentially be up to 1,000 times faster.
