Make holograms real, fast and accurate

We have already mentioned the development of holograms in space without the
need for devices that recreate the artifacts, now it is possible to do them in an ultra-fast and very precise way. Scientists at the Lawrence Livermore American Laboratory in California have developed a technique that can create complex objects in seconds, we can say using Shannon’s sampling theorem for imaging, now being three-dimensional.
This technique creates the objects in layers simultaneously, the details were published in the journal Science Advances in December 2017, there are two really important innovations there, the possibility of creating real images in ultra-fast mode using a photosensitive resin recreating 3D printing with a powerful laser which hardens this resin making it a plastic.
This can also be done with metals using electron beam and a metal powder instead of the resin, so does not need the numerous supports required for 3D printers. LLNL engineer Maxim Shusteff, who leads the study, told New Atlas: “The fact that you can make totally 3D parts, everything in one step really overcomes a problem in additive manufacturing”, now holograms can return to material parts.
Another option would be live tissue bio-printing: “We made a good first attempt,” Shusteff said, “but we have not yet taken it to the limit of its performance, so the space is open to us and others to demonstrate what this approach is able to do. “living tissue bioprinting. “We made a good first try,” said Shusteff,
If 3D printing was already heralded as a revolution, this new technique promises to further accelerate this process
