Researchers are developing methods to insert DNA-like info into 3D printed objects.
Researchers at ETH Zurich have now collaborated with an Israeli scientist to develop a means of storing extensive information in almost any object. “With this method, we can integrate 3-D-printing instructions into an object so that after decades, or even centuries, it will be possible to obtain those instructions directly from the object itself,” explains Robert Grass, Professor at the Department of Chemistry and Applied Biosciences.
As a use case, the researchers 3-D printed a rabbit out of plastic that contains the instructions (about 100 kilobytes’ worth of data) for printing the object. The researchers achieved this by adding tiny glass beads containing DNA to the plastic. “Just like real rabbits, our rabbit also carries its own blueprint,” Grass says.
