    check your units. my hair is fine, but it isn’t 100nm fine!

    yawn. Sick of hearing about 3D printing. IMHO the fruits of this much heralded revolution in maker-dom is nothing more than hi-tech knick knack.

       Speaking as a skeptic of 3D printing generally, I’m still favorably impressed by this particular implementation. Working on this scale allows for a whole world of neat effects, and it’s comparatively fast.

    Not going to get 30nm resolution from near infrared (700 nm). Maybe 30 µm was meant?

    • John Vance says:

      My first thought as well, but check the scale bar in that image; the features are definitely submicron. Based on one of the company’s datasheets ( http://www.nanoscribe.de/data/Ressources/493_1-Data_Sheet_DiLL.pdf ), maybe they’re taking advantage of the laser’s intensity spread and have a substrate that only responds to the intensity at the very center? Or the rapid laser pulses mean they can work with photons as particles rather than waves?

      • Lionel Brits says:

        Agreed, sub-micron, but ~700nm is also sub-micron. I’m guessing that their feature size is slightly larger than the wavelength of the laser, i.e., close to diffraction limited.

    • subgranules says:

      The smallest reported spot (point-spread function) for the sort of laser they use is about 30nm, but to get that you have to play tricks with the material you excite (en.wikipedia.org/wiki/STED_microscopy). But its unclear to me if they can do anything like this.

      • Lionel Brits says:

        You can get beyond diffraction limits with things like multiple patterning: https://en.wikipedia.org/wiki/Multiple_patterning

    • AnthonyC says:

      It’s a two-photon polymerization process. The laser can only cure the resin (normally a UV process) near the very center of the beam. Hence the resolution boost.

    I hope they print a tiny gun.

    Nanites, here they come! (Just need to get the self-replicating part down, which I’m sure is just a minor wrinkle :) ).

  6. Boris Bartlog says:

    We’re down to the point where the feature size can be easily described in terms of the number of atoms, too. Those 30nm features are only a couple hundred atoms wide.

    German start-up Nanoscribe is commercialized a 3D “micro printer”

    Nanoscribe has commercialized, or is commercializing, make up your mind..

  8. AnthonyC says:

    *as long as it can be made of photopolymers

    Am I the only one who saw this and immediately thought ‘Drexel nanofingers’?
