Additive manufacturing takes a leap in speed. Researchers in China have presented a 3D printing system that produces complete objects in 0.6 seconds, a time that marks a new world record. This development surpasses the known limits of speed in layer-by-layer manufacturing, while maintaining a precise level of detail. The advance has direct implications for sectors that require ultr-fast prototyping or custom production.
The Secret: Accelerated Volumetric Photopolymerization ⚡
The technology does not rely on traditional deposition methods. It uses an advanced variant of volumetric photopolymerization, where a container of liquid resin is illuminated by laser light projections from multiple angles simultaneously. This solidifies the entire piece in a single step, without the need to move the head or the platform. The computational synchronization of the light beams and the special formulation of the resin are key to achieving the reported speed and definition.
Your Printer Now Seems Like a Slow Tortilla Machine 🐌
While you read this, a printer in China has probably produced three dozen custom parts. Meanwhile, ours continues humming its monotonous tune, melting filament for the first layer of a pencil holder. We'll have to update our concept of fast printing: it will no longer be in less than a day, but in less than a blink. Maybe the next problem will be finding an operator with reflexes fast enough to remove the parts from the tray.
