There’s little vacation cheer on this Christmas recording printed by DTU Physics on the Technical College of Denmark.
It is because it’s a document sufficiently small to slot in a single groove of a normal dimension copy. This spectacular feat of engineering marks the world’s smallest vinyl-printed document and options simply 25 seconds of “Rockin’ Round The Christmas Tree”.
In a demo showcased by the college’s DTU Physics group, the Nanofrazor Scholar 3D lithography system prints a 15×15 micrometer recording onto polymer movie. Extra impressively, the depth of the grooves etched into this strip of plaque is barely 65 nanometers deep.

“I have been doing lithography for 30 years, and despite the fact that we have had this machine for some time, it nonetheless appears like science fiction.” I said Peter Bøggild is a physicist at DTU. “We will write our signature on a purple blood cell with this factor to get an thought of ​​the size we’re working at. Essentially the most radical factor is that we are able to create freeform 3D landscapes at this loopy decision.”
Whereas there won’t be a lot practicality in a microscopic Christmas recording, the hassle demonstrates robust advances on the earth of supplies science: the power to control and contour supplies with nanoscopic accuracy. In truth, the DTU workforce believes the drill marks a big analysis advance, contemplating that the method may very well be utilized sooner or later to control different supplies to make issues like small magnetic subject sensors.
