China just blew away the 3D printing speed record with stunning 0.6 seconds feat

A team of scientists from China has found an incredible method of turning holograms into physical objects that is so quick it has broken the 3D printing speed record.

While becoming increasingly important in the modern age of design, 3D printing can be a painstaking process of whirring machinery hour after hour.

But, imagine if you could do your day’s graft in under one second?

Well, one University in China has now found a way to create objects in just 0.6 seconds, smashing the 3D printing speed record.

Tsinghua University breaks 3D printing speed record with sub-second object creation

More and more studies are being poured into the 3D printing process as the technology has begun to become a paramount pillar of the design industry.

As displayed in a previous story, though, one man revealed that using the machinery can be a very long process filled with hours of whizzing and whirring.

But fear not, as a team at Tsinghua University has created complex millimeter-scale objects in 0.6 seconds by projecting holograms.

Regular 3D printing applications scan the object designed on a computer before layering one thin layer of materials at a time, building up the object until the sculpture is completed.

But this new format sees holographic images being formed and then, in layman’s terms, splashed into a resin container almost instantly.

There are no mechanical cogs chugging away, no whirring and whizzing, and no waiting for layers to dry in between prints. Just instantaneous production.

So far, the objects produced have been tiny, around a centimeter in size, but could soon be enlarged to make much bigger products.

“The iterative optimization of the holograms for different angles in DISH maintains 19-μm printing resolution across the 1-cm range that is far beyond the depth of field of the objective and enables high-resolution in situ 3D printing of millimetre-scale objects within only 0.6 s,” the team said in a paper published in Nature.

Why is 3D printing so important?

Already, the University is leading the way in 3D printing technology.

Having been the first to produce this new format of instant printing, the team also recently became the first group to create a full concrete bridge from a 3D scanner.

Elsewhere, 3D printing is being used to build supersonic jets and supercars, cutting down the costs of bending expensive metals to aerodynamic shapes.

So far, the world’s largest printer can create a house in under ’80 hours’.

But if it could learn the sub-second holographic technology used by this Chinese university, who knows how quickly we will be able to erect fully 3D-printed neighbourhoods.
