3D Printer Pulls Eiffel Tower Out of Liquid Goo

Rome wasn’t built in a day, but at the rate of construction of ‘one iconic structure every seven minutes’ one wonders if Carbon3D doesn’t have the old adage in its sights.

Harnessing the power of CLIP—Continuous Liquid Interface Production—Carbon3D is calling 3D printing’s bluff. While the still-bourgeoning tech has given us self-defense dresses and brain-operated helmets it’s done it in the shadow of limited material options, frequent jams, and, most crucially, long production times. As a result, it’s failed to live up to its promise of upending manufacturing as we know it.

That bit of industrial magic which conventional 3D printing has yet to figure out is no doubt apparent in watching Carbon3D’s breakthrough technology seemingly pull an Eiffel Tower model out of nothing.

Outside of being jaw-dropping, the printing process Carbon3D employs is between 25 and 100 times faster than what has been available up until this point. That’s the difference between weekend pursuit and industry.

For those floored by the process, it works through a rather innovative means that surely beckons the T-1000 robot from Terminator 2 that inspired its creators. Through CLIP, objects are “grown” from a pool of resin through a balanced ballet of light and oxygen, with UV light triggering photo polymerization and oxygen inhibiting it. The desired object is defined by the careful interplay of resin manipulation.

Though speed is integral when it comes to industry takeover, commercial quality will be just as important in CLIP’s rise. As the electron microscope photo comparison shows, the inconsistent nature of 3d-printed parts is even more apparent at the micro level.

CLIP, on the other hand, is consistent and uniform—and certainly quite lovely where end results are concerned.

Who knew that the next step in manufacturing would be so enjoyable to watch?
