The world is not standing still, and new technologies appear every day. The innovation from the Dutch scientists has amazed the world!
What is this technology and how it is connected with gold bars? Read in the article!
New technologies appear every day. One of the latest popular trends is 3D-printing, which allows printing different kinds of objects.
The scientists from Twente, the Netherlands, developed a new technology of 3D printing based on direct laser induced transfer.
According to the “Popular Mechanics” magazine, the method is based on spraying a thin layer of gold to a transparent underlay with the laser ray focused on these.
The laser affects gold in such a way that it spreads to the underlay in the way of microscopic drops. The diameter and intensity of a laser ray can be controlled, as well as its direction. Also, the printer’s software allows controlling the laser’s work.
Owing to this laser technology, first results were achieved, which is printing 2 milimeters high gold pyramids. Also, scientists succeeded in “drawing” a microscopic copper painting.
Researchers say that gold and copper allow to print any kinds of three-dimensional objects, even having difficult geometrical shapes.
This suggests the possible beginning of the new era of producing gold bars.
The Green Gold Online Gold Shop provides its clients with the investment gold bars of the highest quality for them to have sustainable economy.
